Smooth surface

When should I use a GSZ series screw jack?GSZ series screw jacks are designed for applications where smooth surfaces are required. These screw jacks are easier to clean and thereforeideal for applications in the food processing industry.

NOTE:SHZ and MSZ series units made from cast iron and aluminium are available as spare partson request. We will be happy to offer advice on conversion to the new Z and GSZ types.

Heavy duty screwsThe screw diameter is a critical factor in long-stroke applications. Long-stroke screwshave to be overdimensioned to preventbuckling and other problems. However, increasing the diameter of the screw means that the gearbox also has to be oversized accordingly.

To overcome this problem, the Z-35 and the Z-50/Tr50 are specially designed with stronger screws to prevent buckling onapplications with long strokes. The screw doesnot therefore require overdimensioning andconsequently a compact gearbox can also beused on long-stroke applications.

2 Z series screw jacks KGT

Z series screw jacks KGT2


Pitch accuracy0.05 mm / 300 mmMaterial: 1.1213 (Cf 53), induction hardenedand polished.

No self-locking!Because of the lack of friction, a holding brakeis necessary: a motor brake or a springpressure brake is required.

Temperatures, duty cycleOperating temperature range -25°C to + 80°C.The duty cycle can be up to 4 times higherthan for trapezoidal screws (see diagrams), andat long strokes up to 2 times higher than fortrapezoidal screws.

Most screw jacks use trapezoidal screws Tr,because they are simple, robust and inexpensive.The proportion of screw jacks that use ballscrews is however constantly increasing.The reasons for this are primarily their pitchaccuracy, their high efficiency (less powerconsumption and less heat generation) and thehigher pitches available, which permit higherstroke speeds.

Service lifeHeavy loads reduce the service life of the KGT.Tell us the load and stroke speed and we willcalculate the service life.

ContaminationAll nuts are fitted with scrapers. For heavycontamination and fine dust/chips,we recommend fitting bellows or a spiralspring cover.

Escape/rotation protectionUnder no circumstances may the nut bescrewed off the screw. We therefore alwaysprovide escape/rotation protection onthe S version.

Start ramp / braking rampWe recommend using a frequency converteror a soft start device, especially for high leadscrew jacks. This allows regulation of the startramp / braking ramp. This ensures protectionfor the entire system.Safety clearance L3 can also be reduced at your own discretion, in particular for high pitches.

Grease nipplesThe standard position of the grease nipple onthe S version is on the gearbox face “C”.Optionally, face A is available. Faces B and Dare available on request.

Safety nut SIFA

FunctionA safety nut is designed for use wherestripping and break up of the thread couldcause a hazard to persons.A safety nut can also provide protection forother equipment against the consequences ofmachine failures and downtimes.

WearOnce the wear exceeds max. 25% of the screwpitch, the load nut (R) or the gearbox (S) mustbe replaced.

MonitoringWear and thread play should be checked anddocumented at regular intervals (depending onthe duty cycle).This allows the fitting of replacement parts tobe planned ahead, reducing unscheduledsystem downtime.

Electrical monitoringElectrical monitoring gives a signal when wearreaches approx. 25%. This signal can bedisplayed immediately at a central controlpoint. Replacement of the worn parts can thenbe scheduled.

WARNING! Switch S1At 25% wear the limit switch S1 trips.The customer must detect this signal.This enables substitution to be planned wellin advance and therefore prevents anyunnecessary downtime.

STOP! Switch S2If after the first signal operation of the jackcontinues, the nut will continue to wear untilthe thread is worn through. When the threadis worn through, the safety nut takes the load.The limit switch S2 trips.The customer must detect this signal and stop the system.

Pitch accuracy0.05 mm / 300 mmMaterial: 1.1213 (Cf 53), induction hardenedand polished.

No self-locking!Because of the lack of friction, a holding brakeis necessary: a motor brake or a springpressure brake is required.

Temperatures, duty cycleOperating temperature range -25°C to + 80°C.The duty cycle can be up to 4 times higherthan for trapezoidal screws (see diagrams), andat long strokes up to 2 times higher than fortrapezoidal screws.

Most screw jacks use trapezoidal screws Tr,because they are simple, robust and inexpensive.The proportion of screw jacks that use ballscrews is however constantly increasing.The reasons for this are primarily their pitchaccuracy, their high efficiency (less powerconsumption and less heat generation) and thehigher pitches available, which permit higherstroke speeds.

Service lifeHeavy loads reduce the service life of the KGT.Tell us the load and stroke speed and we willcalculate the service life.

ContaminationAll nuts are fitted with scrapers. For heavycontamination and fine dust/chips,we recommend fitting bellows or aspiral spring cover.

Escape/rotation protectionUnder no circumstances may the nut bescrewed off the screw. We therefore alwaysprovide escape/rotation protection on the Sversion.

Start ramp / braking rampWe recommend using a frequency converter or a soft start device, especially for high leadscrew jacks. This allows regulation of the startramp / braking ramp. This ensures protectionfor the entire system.Safety clearance L3 can also be reducedat your own discretion, in particular for high pitches.

Grease nipplesThe standard position of the grease nipple onthe S version is on the gearbox face “C”.Optionally, face A is available. Faces B and Dare available on request.

FunctionA safety nut is designed for use wherestripping and break up of the thread couldcause a hazard to persons.A safety nut can also provide protection forother equipment against the consequences ofmachine failures and downtimes.

WearOnce the wear exceeds max. 25% of the screwpitch, the load nut (R) or the gearbox (S) mustbe replaced.

MonitoringWear and thread play should be checked anddocumented at regular intervals (depending onthe duty cycle).This allows the fitting of replacement parts to beplanned ahead, reducing unscheduled systemdowntime.

Electrical monitoringElectrical monitoring gives a signal when wearreaches approx. 25%. This signal can bedisplayed immediately at a central controlpoint. Replacement of the worn parts can thenbe scheduled.

WARNING! Switch S1At 25% wear the limit switch S1 trips.The customer must detect this signal.This enables substitution to be planned wellin advance and therefore prevents anyunnecessary downtime.

STOP! Switch S2If after the first signal operation of the jackcontinues, the nut will continue to wear untilthe thread is worn through. When the threadis worn through, the safety nut takes the load.The limit switch S2 trips.The customer must detect this signal and stopthe system.

Function R version

The load is borne by the duplex nut.The safety nut runs alongside the duplex nut,bearing no load. If the nut thread is wornthrough due to wear, the SIFA takes the loadon the duplex nut.

Direction of loading, compressive or tensileA drawing showing the direction of loadingis necessary in order to ensure thesafety function.The SIFA-R operates in only one directionof loading.

Make sure you fit it the right way up:

Dimension A is approx. the original setting.Dimension A must be measured anddocumented by the customer, and referred towhen checking.This enables substitution to be planned well in advance and therefore prevents anyunnecessary downtime. When the thread isworn through, take the equipment out ofservice immediately.

Application:(Welded) fabrications often exhibit angularerrors, which lead to rapid wear of thetrapezoidal screw nuts. The self-aligning nut PMcan compensate small angular errors on theattachment face up to maximum +/-3°.A large grease reservoir increases the maintenanceintervals and extends the service life.

CAUTION:Self-aligning nuts cannot compensateparallelism errors between screws or betweenscrews and guides. Take care to ensure precisealignment. The attachment faces for thegearboxes must therefore be exactly at rightangles to the guides.

Fitting the bellows

AZ=ExtensionZD=Compression

The bellows protect the screw against dirt andmoisture.

PLEASE NOTE:The bellows must not be compressed to lessthan the ZD dimension nor extended beyondthe AZ dimension.If the stroke is longer than 1000 mm, fit abellows with an extension block. Take intoconsideration that when the bellows is fitted

horizontally it must not touch the screw: Risk of serious damage! Use support rings toavoid such damage.Protect the screws, especially during on-site assembly, against: building site dust,grinding dust from angle grinders,

Material: PVC, NBR (GSZ-2), operating temperature+70°C up to max. +85°C, cold fracture temperature -32°C, incl. 2 galvanised hose clips. CAUTION: For screw extensions, see Sections 2+3identical to the previous MSZ type

Fitting instructions:Spiral springs can be used on chip-generatingand non-chip generating machines.The illustrations show how to fit differenttypes of spiral spring covers to variousscrew jacks.Centring bushings are required when assemblingcombinations of different parts; we can includethese in our quotation on request.

IMPORTANT:Spiral springs must under no circumstances beallowed to uncoil. For technical reasons,please specify in your enquiry whether thespiral spring is to be installed horizontallyor vertically.

If installation is to be vertical, we recommendthat the larger diameter is at the top,

as shown; if it is to be horizontal, the tapershould be away from the direction of flow ofthe chips or other particulate.

A slight film of oil on the spiral springimproves its operation and extends itsservice life.

Pivoting – Z-5 to Z-25

Integrated pivot bearingSimple and economical design:Pivot bushes are incorporated in the gearbox housing.

LubricationThe bronze bushes are PTFE-coated and therefore require nolubrication in normal service. We recommend regularlubrication for high loadings.

Design tipFor large motors, long strokes and high load cycles, thevariant with the pivot bearing plate KAR is preferable,because the weight of the motor is then taken by the pivoting points and does not affect the screw.

Material: Cast steel, quenched and tempered, corrosion-resistant

Refer to thepermissible loadslisted in Section 8

F

Integrated pivot bearingSimple and economical design:Pivot bushes are incorporated in the gearbox housing.


From Z-500 the gearboxis mounted the oppositeway round, since thefootplate is broaderthan the rest of thehousing:

Pivot bearing plate from Z-35The use of the pivot mounts LB directly within the gearboxhousing is the best and most economical solution. Designconsiderations may in some cases necessitate the use of apivot bearing plate.

Other sizes of pivot arrangements “R” and “P” are availableon request.

MA distance between centres

Pedestal bearing: YES/NO?The installation situation is very importantwhen selecting shaft dimensions. For example,the cost of a larger diameter connecting shaftnot requiring additional pedestal bearingsupport can be considerably less than thecost of a smaller connecting shaft requiringcostly sub-structures for the additionalpedestal bearing.For this version we use the rigid hub version sothat no radial misalignment can occur in thepedestal bearing.

Three-phase AC motor Three-phase AC motor with brake

Ordering example:

90-P4-1.5-B5-B-2W SizeNumber of poles - speed4-pole = 1500 rpmPower [kW]Designwith brake (if required)with a second shaft end (if required)

*Power is higher than the IEC standard (progressive)

SpeedsThree-phase AC motors have differentrotational speeds depending on the number ofpoles. Generally we recommend our standardmotor with 1500 rpm (4 poles).Other numbers of poles are available onrequest. Pole-changing motors allow a choiceof 2 different rotational speeds.

Geared motorsGeared motors are available for particularprojects on request.

Operation with frequency convertersEspecially for larger screw jacks and systems,we recommend the use of a frequencyconverter to achieve smooth start-up andbrake ramps. This minimizes start-up noise andextends the service life of the gearbox.

When operating with a frequency converter,remember that if the motor is to be operatedfor extended periods at frequencies less than25 Hz, its fan must be driven separately. This isnecessary to ensure adequate motor cooling.

Connection arrangementThe motors usually have a terminal board with6 terminals and a protective earth terminal inthe terminal box. The stator winding can beswitched into star or delta connection usingthe connection links.Star/delta starting is not suitable for screwjack systems because full torque is requiredimmediately on starting.

Operating voltage 230 V delta:Motor windings 230/400 VOperating voltage 400 V delta:Motor windings 400/660 V

Direction of rotatingMotors can be arranged for either direction ofrotation When the line phases L1, L2, L3 areconnected to the motor terminals U1, V1 W1,the direction of rotation is clockwiseSwapping over two of the supply lines reversesthe direction of rotation.

When operating a braked motor with afrequency converter, a separate actuation linefor the brake must be provided via thefrequency converter.

Braked motorWe recommend using a braked motor tominimise the overrun time of the system.Where a screw jack is fitted with a ball screwor a double-pitch screw, a braked motor isabsolutely essential. We supply motor brakesas standard for a connection voltage of230V AC / operating voltage 205 V DC,with bridge rectifiers. Other connection voltages (24V DC, 400V AC,500V AC) are available on request.

Temperature monitoringGenerally we do not supply temperaturemonitoring because screw jack duty cycles arenormally quite low or the motor is adequatelydimensioned.Temperature control thermal resistor (PTC) orbimetal (TKÖ) is available on request.

Some types are available ex stock with thermalresistor (PTC).

Rotary pulse encoder DIGWe have developed an intelligent intermediateflange which greatly simplifies recording speedand direction of rotation as well as connectingto supervisory control system. Previously thisrequired complex assembly and additions tothe drive system; the intelligent flangeachieves this economically and is very easy tofit, even when retrofitting drives.

This magnetic pulse encoder is fitted as anintermediate flange between motor and motorflange. This considerably simplifies theintegration of incremental encoders in drivesystems, whether for purposes of speedmatching, of positioning control (e.g. for dosagecontrol) or for synchronisation.We supply a 2 m cable as standard.

Spring pressure brake FDB

FunctionA spring pressure brake is used:- when there is a lack of self-locking

characteristics (high-pitch, double-pitchscrews, ball screws KGT)

- where self-locking characteristics aredoubtful (as a safety precaution)

- for increased accuracy of stopping position,independent of the lubrication situation

GeneralThe braking torque is generated bycompression springs when the brake isdeenergised. The brake is releasedelectromagnetically by the application of DCvoltage. The protective rings shield the frictionfaces from external influences. The standard version has protection class IP 54.

Mode of operation

The compression springs (3) exert force on thearmature disc (4) which is free to move axiallyand which presses the brake rotor (5) againstthe flange (6). The brake rotor in turn is tightlymounted on the hub (2).The shaft is then braked. Application of DCvoltage to the field windings (1) in themagnetic body generates a magnetic forcewhich pulls the armature disc towards themagnetic body. The brake rotor is freed andthe brake is released.

In the event of an emergency stop or a powerfailure, the spring pressure brake ensures thatthe load is safely braked to a stop.

Electrical supplyThe spring pressure brake requires a DC supply.Half-wave and bridge rectifiers are available toprovide the power supply to the brakes fromthe AC mains supply.

Because of the inductance of the solenoid coil,the release of the armature disc on loss ofpower is not immediate. When the switchingoff takes place in the AC line from the rectifier,this delay is relatively long.The delay in switching off can be reduced ifthe connections available between the rectifierare used to switch the DC line (6 times faster).

If the switching is performed on the AC side,a bridge should be made to the switchcontacts.

Manual releaseIf a manual release lever is fitted, the brakecan be released mechanically, e.g. in the eventof a power failure.

Lubricants

Always use the correct lubricants for a longservice life!These lubricants have been carefully selected to suitthe screw jack requirements.Caution should be exercised in using other greases!A “good” grease may not always be the “right” grease.

The important question is whether it matches therespective requirements.

Infinitely adjustable from 1 to12 months metering time

Trapezoidal screwInspect the trapezoidal screw regularlyand regrease it depending on theoperating cycle. Use the grease that werecommend. These greases are ideallymatched to the operating requirements of our screw jack systems.

Standard grease:Castrol Tribol 4020/460-2 (up to size 150)Castrol Tribol 3020/1000-2 (from size 250)

As well as the standard greases we also offer greasesfor special applications:• High temperature/high duty cycle• Low temperature• Heavy duty• Food industry• Clean room• Vacuum, etc.

Most greases are available ex stock. The exactapplication and the load cycles are important whenmaking the selection. The best strategy is to send usthe completed enquiry checklist (Section 7).

Ball screw KGTLubricate the ball screw KGT every 300hours of effective operation. For heavy-duty systems every 100 hours.

Grease quantity:Guidance value approx. 1 ml per cm screw diameter.

Standard grease:Castrol Tribol 4747/220-2

Hot-rolled U-profiles

Rolled U-profilesThis U-profile is rolled and pickled in S235JRmaterial, in lengths up to approx. 8 m.

U-profiles are made of hot-rolled 18MnNb6in lengths up to approx. 12 m.The advantage compared to material S355J2G(St52-3) is that the elastic limit and tensilestrength are considerably higher. Our profiles are generally aligned.We supply all profiles in fixed lengths.

On request we can supply profiles in paintprimer finish or hot-dip galvanised. We will be happy to offer fully finishedprofiles to your requirements, e.g. drilled,milled, with welded-on elements.

Design advice

Parallelism and angular relationships

Attention must be paid to the parallelism andcorrect angular relationships of mountingsurfaces, gears, nuts and guides to each other.The same applies for exact alignment of gears,pedestal bearings, connecting shafts andmotors to each other.

GuidesGuide bush play in the screw jack gearbox canbe between 0.2 mm and 0.6 mm depending onthe size. This is just a secondary support anddoes not replace a guide system specificallyprovided to cater for lateral forces.

- Frequency converter serves to increase themotor speed to more than 1500 rpm.

Please note the maximum gearbox speed.

Slower:- Motors with more poles/lower speed

(6, 8, 10 or 12 poles)- Frequency converter

(CAUTION: if the motor is to be operated forextended periods at frequencies less than 25 Hz, adequate cooling must be assured,e.g.: separately driven fan)

- Geared motor (CAUTION: do not exceed the maximuminput torque)

- Bevel gearbox with gear reduction(only suitable for certain applications)

Temperature and duty cycleScrew jacks are generally not designedfor continuous operation. Refer to the diagram on the gearboxpages (Sections 2 + 3) for themaximum duty cycles (ED). These are reference values but vary accordingto usage conditions. In borderline cases,select a larger screw jack or contact ourproject technicians. Operating temperatures must not exceed 60°C(gearbox) or 80°C (screw) (higher valueson request).

Rotation protectionOn the version S, the translating screw is freerunning within the gearbox (worm wheel). The screw must be protected against rotation –otherwise it would rotate due to the friction inthe worm wheel. This can be achieved byfixing the screw to an external guidancesystem or by using our rotation protection (VS)(in the protective tube).

Design and specificationSelection and dimensioning is the customer’sresponsibility, because we are not familiar withthe design criteria such as installation locationand type of application. On request we canprovide support during selection andspecification and make proposals withsubassembly drawings and calculations basedon your application parameters. You can thenexamine and approve these drawings and theirparts lists.These then serve as basis for production andpreassembly and assist your employees duringinstallation and fitting. We guarantee thequality of the machine elements as describedin the catalogue. The gearboxes are designedfor industrial use at the loads and duty cyclesspecified in the catalogue.

If your requirements are not covered by ourcatalogue descriptions, please contact ourproject technicians. We generally deliveraccording to our current Terms of Sales andDelivery (Section 10).

Lifting speed

There are several parameters which affectthe lifting speed:

Faster:- double-pitch screw (not generally held in stock): This doubles the lifting speed (CAUTION: max. input torque, not self-locking - brake required!)- increased screw for the R version (next larger

size of gearbox): depending on the screwjack size, this will give a somewhat greaterpitch / lifting speed

- Ball screw: Various pitches are available (CAUTION: not self-locking– brake required!)

Direction of rotation and movement

Check the direction of rotation required forthe system and record this on the drawing orselect one of our standard system layouts(Checklists). With T bevel gearboxes, thedirection of rotation can be changed simply byturning the gearbox around.

Self-locking / overrunningScrew jacks with a single-pitch trapezoidalscrew have a limited self-locking capabilitywhich cannot always be relied upon, especiallywhere impact loads or vibrations are present(brake recommended).

The overrun after the motor has been switchedoff varies depending on the application.To minimize overrun, we recommend using abraked motor or a spring pressure brake FDB.A braked motor is essential for double-pitchscrews or ball screws, because these are notself-locking.

Safety distanceSafety distancesbetween moving andstationarycomponents must bemaintained otherwisethere is the risk ofthe screw jackreaching a blockedposition (see GearboxDimension Sheets).

AccuracyThe repetition accuracy of the gearbox can beup to 0.05 mm when moving to the sameposition again underthe same loadconditions. This requiresmeasures on thedrive side, such as a3-phase AC motorwith a brake inconjunction with afrequency converter,a rotary pulse encoder or a servomotor withencoder, etc.

The pitch accuracy for trapezoidal screws is 0.2 mm over a 300 mm screw length, and0.05 mm for ball screws over a 300 mm screw length.

Under alternating loads, axial play can be upto 0.4 mm on trapezoidal screws and 0.08 mmon ball screws (when new).

DriveWe recommendthe use of afrequencyconverter toachieve smoothstart-up andbrake ramps. This minimizes start-up noise and extends theservice life of the gearbox.

Trial runs!Trial runs without load and under load innormal operating conditions are necessary toensure reliable operation. Do not exceedsystem duty cycle when loaded. These on-site trial runs are necessary toachieve system alignment and to eliminateany factors which may impair operation.

Spare partsTo protect against loss of production causedby high duty cycles or high loads, werecommend keeping a set of screw jack spareparts (including screws, accessories and withassembly drawings) at your location or at yourcustomer’s location.

Theatre stage designWe supply lifting equipment which satisfiesthe current regulations on theatre stage design.

Land vehicles, aircraft and water craftOur extended warranty terms generally do notapply to machine elements used in any landvehicles, aircraft and water craft. Specialindividual terms may be agreed on inquiry.

Ambient conditionsPlease specify any ambient conditions that are outside normal industrial environmentalconditions (Checklists - Section 7).


Technical appendix8

Design advice

Additional features where alignment may be aproblem are the integrated pivot bushings in thegearbox or the pivot bearing plate KAR(see Section 4).

For steel and plant construction: We supply standard heavy-duty linear guidesincluding bearings. Their stability, long servicelife, avoidance of geometric errors and ability toaccept lateral side forces are decisive argumentsfor using such guides.

See Section 6 for linear guides.

LubricationAdequate lubrication isdetermine for theservice life of a screwjack. Therefore ensureadequate lubrication ofscrews, gearboxes androtation protection. The red lubrication stripfor rotation protection can be mounted inalternative positions to meet yourrequirements (please specify).

Please also refer to our lubricator and ourInstruction manual.

Lubrication for short stroke applicationsS version:For short strokeapplications (stroke < gearboxheight), take particularcare to ensurelubrication of thetrapezoidal screw. The simplest tactic is tospecify the screw jackwith a longer stroke than the gearbox height,and occasionally perform a lubrication stroke.Otherwise, contact our EngineeringDepartment for a suitable solution.

R version:If stroke length < nutheight, use a nut withlubrication capability(such as a duplexnut DM).

Instruction manualPlease refer to our Instruction manual duringthe design phase (www.zimm.at).

Design advice for steel and plantconstruction:Hardly any assembly problems arise whenscrew jacks are used in machine tools, becausethe relevant surfaces are machined faces.

In steel and plant construction however,frequent geometric errors can occur in weldedstructures, despite accurate fabrication work.The interaction between different componentscan also cause alignment issues.Attention must be paid to the following:

Parallelism / angular relationships:

Screws and guides must be parallel to eachother, otherwise the equipment can seize upduring operation. All mounting surfaces forthe gearboxes must be exactly at right anglesto the guides, jamming may occur, leading torapid wear and/or serious damage.

Squeaking noises can also occur on R versions.The mounting surfaces for the nuts must alsobe at right angles.

ZIMM has developed the self-aligning nut PM(see Section 4) to save time and costs here.

Printing errors, dimensional mistakes etc. and also technical changes and improvements are excepted. Drawings are valid only when they have beenchecked and approved by both partners in accordance with the order acknowledgement.

Critical whirling speed for R gearboxes

8

The maximum allowable screw speed must becalculated for R version gearboxes (withrotating screws) with long thin screws.To do this, read the theoretical critical speednkr from the diagram. Take into account alsothe additional lengths for screw covers etc.when calculating unsupported screw lengths.Now use the formula together with thecorrection factor for the screw bearingarrangement to calculate the maximumallowable screw speed.

If the calculated maximum screw speed islower than the required speed, select a largerscrew or a double-pitch screw with half thespeed. This must then be checked also.You have the option to use a “increased screw”for the R version (screw for the next largergearbox).

Bear in mind that a larger pitch demands ahigher drive torque.

CAUTION:Long, thin screws can tend to squeak eventhough they satisfy the critical whirling speed! Therefore allow a sufficient margin of safety in the calculation.

Technical appendix8

Drive torque for screw jacks - approximate calculation

CAUTION:We recommend multiplying the calculatedvalue by a safety factor of 1.3 to 1.5 (up to 2for small systems and for low speeds).The values stated assume equal distributionof the load across all gearboxes!

MR - Overall drive torquefor the entire system.

MG - Drive torque foran single gearbox

MA - Starting torque max. 1.5 x MR

Example (example from page 162, 12 kN per gearbox)

MR = MG x 4.9 = 5.97 Nm x 4.9 = 29.25 Nm x safety factor 1.4 = 40.95 Nm

MR = MG x 2.4

MR = MG x 2.1 MR = MG x 3.1 MR = MG x 3.6

MR = MG x 4.9 MR = MG x 7.1 MR = MG x 4.8

MR = MG x 3.5 MR = MG x 3.6

CalculationThe drive torque required for a lifting system isthe sum of the torques for the individual screwjacks and increases due to frictional losses ontransfer components such as couplings,connecting shafts, bevel gearboxes etc.

To simplify the calculation, the followingfactors are used to determine the drive torquefor the most common system layouts.

Technical appendix

Drive torque for screw jacks – precise calculation

8

The following calculation example takes account of the efficiencyof the connecting shafts (η 0.95) and bevel gearboxes (η 0.9).

Drive torque: MG = + ML [Nm]F [kN] . P [mm]

2 . π . ηgearbox . ηscrew

. i

Example:

1) MG = + 0.36 Nm = 5.97 Nm12 kN . 6 mm

2 . π . 0.87 . 0.391 . 6

3) 5.97 Nm + 6.28 Nm = 12.25 Nm 12.25 Nm . 1.5 = 18.38 Nm-> so KSZ-25-L is OK (see Section 5)

41.34 Nm –> we need a KSZ-50-L(see Section 5)

Motor selection: 132M-P4-7.5 kW (50 Nm)(for motors see Section 4)

Z-25-SNF = 12 kN (dynamic lift load per gearbox)ηgearbox = 0.87 ηscrew = 0.391P = 6 i = 6

Formula for the gearbox::

Efficiencies:Connecting shafts: η 0.95Bevel gearbox: η 0.90

2) = 6.28 Nm5.97 Nm

0.95 (efficiency of the connecting shaft)

4) = 13.61 Nm12.25 Nm

0.9 (efficiency of the bevel gearbox)

5) = 14.33 Nm13.61 Nm

0.95

6) 12.25 Nm + 14.33 Nm/0.9 = 29.53 Nm

7) 29.53 Nm . 1.4 = 41.34 Nm

We recommend multiplying the calculated valueby a safety factor of 1.3 to 1.5 (up to 2 for smallsystems and for low speeds).

A quicker methodThe tables on the following pages allow you tocalculate the required screw length andprotective tube extension length yourself.This lets you quickly calculate the fittingdimensions of your screw jack.

PrincipleDepending on the version and accessories usedthe screw (and the protective tube on the S version) are extended.These dimensions are minimum requirements.For special fitting situations, please provide adrawing or contact our project technicians.

Stroke + basic length (+ various extensions for variants/accessories)

Example S:

Z-25-SN, stroke: 250 mmBellows Z-25-FB-300 (ZD=70mm)Fixing flange BF (means the bellows do not require an fixing ring)Rotation protection VSLimit switch ES

Screw length Tr:

250 + 180 + 44 + 45 = 519 mmStroke Basic length Bellows Limit switch + Screw length

See Section 4 for the length calculation for connecting shafts.


Technical appendix8

Length calculation – screw, translating version S(The length calculation is identical for Z and GSZ)

1) The value will be added to or subtractedfrom the ZD dimension of the bellowsdepending on the sign and the result thenadded to the screw length. Applicable only to Tr single-pitch screws,not to double-pitch and KGT screws.

2) Limit switches ES are always used incombination with rotation protection VS(VS is included in the extension).

3) KGT 50: L6=82

4) KGT 50: L6=118

5) KGT 63: L6=90

6) KGT 63: L6=124

7) KGT 63: L6=118

Screw extension for spiral spring cover SF: Since the extension for spiral spring coversvaries according to the fitting, this variantmust be determined from a drawing. We wouldbe pleased to prepare this drawing for you.

Gearbox lubrication

Gearbox lubricationThe gearbox is sealed and isfilled with high-preformance syntheticgrease (gearboxes from Z-250 are oil-filled). The gearbox is lubricatedfor life in normal operation.

3 Trapezoidal screwInspect the trapezoidal screwregularly and regrease it depend-ing on the operating cycle.Use the grease that werecommend. These greases are ideally matchedto the operating requirements of our screwjack systems.

Ball screw KGTLubricate the ball screw KGT every300 hours of effective operation.For heavy-duty systems every100 hours.

Grease quantity: Guidance value approx. 1 mlper cm screw diameter.

Lubrication for short stroke applications

General

S version:For short stroke applications(stroke < gearbox height),take particular care to ensure lubrication of thetrapezoidal screw.

The simplest tactic is to specify the screw jackwith a longer stroke than the gearbox height,and periodically perform a lubrication stroke.Otherwise, contact our EngineeringDepartment for a suitable solution.

R version:If stroke length < nut height,use a nut with lubricationcapability (such as a duplexnut DM).

Special lubricantsFor special applications and for theearlier MSZ gearboxes we can offersuitable lubricants in each case. These include amongst others: - High-temperature grease- Low-temperature grease- Food grade grease- Clean room grease, etc.

Other greases, contaminationUsing multipurpose greases and other greases can significantly impair operation and shorten the service life.If the screw becomes dirty, clean and regrease it.

Long-life systemsThe grease used in long-life systems (such as working platforms and theatre stages) loses its lubricating properties after about 5 years.Dust and dirt penetration intensify this effect. We recommend complete cleaning and regreasing after 5 years.If mineral greases are used, this may benecessary after only 2-3 years.

Operational reliability and safety

8

Operational reliability and safetyOperational reliability and safetyare just as important forindustrial systems as for theatrestages and other systems.

Design and specificationDuring the design and specification phase,pay special attention to the load capacity ofthe drives and accessories in their proposedinstallation situation. Plan your system withappropriate safety for attachment, movementand transport elements.

Please note the design advice given inSection 8.

Where the system is safety-relevant, fit a safety nut SIFA.If the nut thread is stripped dueto wear, the SIFA takes the load.An electronic control is availableon request.

InstallationCorrect and careful installationis essential for trouble-free andsafe system operation. Please refer to our instructionmanual included with eachdelivery. You can download these from theInternet at www.zimm.at

Inspection and maintenanceRegular inspection andmaintenance are necessary tomaintain reliability.

Check the following during theregular inspections: Visual condition, attachments andconnections, wear on the trapezoidal thread and the level of lubrication.Comply with our lubrication instructionsand use only the lubricants we recommend.Please consider our automatic lubricator Z-LUB.

Spare partsTo protect against loss ofproduction caused by highduty cycles or high loads,we recommend keeping a set ofscrew jack spare parts (includingscrews, accessories and with assemblydrawings) at your location or atyour customer’s location. A screw jack canmost economically be repaired by acomplete exchange.

Technical appendix8

Temperature

Normal temperature(-20°C to +60°C)A normal temperature range is up toabout 60°C gearbox operatingtemperature. The highesttemperature rise is at the shaft sealring and on the trapezoidal screw.Various tests have shown that thetemperature rise of a Tr screw istwice that of the gearbox housing.

Example: At an ambient temperature of 20°C,the housing reached about 60°C (rise of 40°C)and the Tr screw about 100°C (rise of 80°C).

We recommend the temperature of Tr screwsshould not exceed 100°C when using standardgearboxes.

Low temperature (-20°C to -40°C): Seals and most of our greases arespecified in principle fortemperatures down to -40°C.Experience has however shown thatapplications below -20°C are critical.The grease becomes very viscous andhard to move and it becomesdifficult in particular to satisfy thebreakaway torque.Generally speaking, all components must besized adequately for minus temperaturesbecause the material strength is reduced(apart from aluminium).

We recommend low temperature grease fortemperatures less than -20°C. Our standardgearboxes up to size Z-150 are filled asstandard with a synthetic fluid grease that isalready suitable down to -40°C.

High temperatures (+60°C to +160°C):For ambient and operatingtemperatures (gearbox housing)higher than 60°C we recommendgearboxes with high-temperaturegrease and FPM seals. These cangenerally permit operatingtemperatures up to 160°C.

High temperatures (up to +200°C):At temperatures up to 200°C we useFPM seals and a special grease.

We offer appropriate heat-resistantcomponents for high temperatureapplications.

Temperature range of standard parts:

Standard screw jacks -25°C to +80°C (-40°C to +100°C)High temperature screw jacks up to 160°C, or 200°CRound bellows -32°C to +70°C (max. +85°C)Polygonal bellows -15°C to +70°C (no exposure to direct sunlight)Limit switch -30°C to +85°CRotary pulse encoder DIG -40°C to +80°CMotors above 40°C reduced power, e.g. factor 0.8 at 60°CConnecting shafts VWZ+KUZ-KK 0°C to + 70°C, reduced from -20°C to +100°C (max. +120°C)Couplings KUZ -20°C to +70°C, reduced from -40°C to +100°CBevel gearboxes -10°C to +90°CBall screws KGT -20°C to +80°C

For lower and higher temperatures, pleaserequest information on the component fromus, with your checklist (Section 7).

Ambient and operating temperatures:The ambient temperature is relevant forcomponents such as limit switches or bellows.For gearboxes, the operating temperature isslightly or considerably higher than theambient temperature, depending on theduty cycle.

The ambient temperature is very important forsystem operation.Always inform us about ambient temperatureand conditions, especially if these deviate fromthe usual 20°C to 25°C.

Food industry sectorThe foodstuffs sector operates at a very highlevel of automation. On the one hand thispromotes a very high level of hygiene, on theother hand it permits intelligent and efficientsystems for economic production

Resistant against corrosionOur Z and GSZ series are corrosion-resistantand are therefore very suitable for mostapplications in the food industry. The GSZgearbox with its smooth surfaces isparticularly suitable. The Z and GSZ series are not suitable forspecial applications where stainless steelis mandatory.

Screw jack systemsWe supply gearboxes and systems with foodgrade grease to the food industry. Our foodgrade greases are FDA-approved. Use thechecklist in Section 7 to enquire about thesystem you require and also specify theparticular requirements for your application.

SectorsVarious fields such as semiconductorproduction, flat screen production, optical andlaser technology, spacecraft production etc.demand high cleanliness, which means thatclean room standards must be maintained.

Clean roomA clean room is a room where theconcentration of particles in the air iscontrolled and satisfies defined cleanlinessclasses. It is important to keep the particlecontamination caused by work materials,lubricants and drives to a minimum.

Your systemUse the checklist in Section 7 to enquire aboutthe system you require and also specify theparticular requirements for your application.We can then offer you a system to meet yourrequirements.

Resistant against corrosion

Corrosion-resistant as standard - no need for paintingAll relevant components of the ZIMM –Z series and GSZ series are coated as standardwith various single-layer and multi-layersystems resistant against corrosion.This eliminates the need for time-consumingand cost-intensive painting.

The colours black, anthracite and silver arevisually neutral and fit in with any colourcombination. The coating are speciallymatched to the various base materials andtheir functions. This ensures high-qualityprotection against corrosion for manyapplication areas.
