Profit from CAVEX in many ways:

Continuous range of worm gear units up to 360,000 Nm in 18 sizes

Specially high torques and efficiencies and long lifetime due to unique gear tooth geometry

High ratios

High overload capability

Rugged design

Low noise levels

Custom and sector-specific solutions

In conformance with ATEX

A worm gear is not just a worm gear. CAVEX proves this over and over again. For more than 50 years. In a wide range of industrial sectors world-wide. The decisive advantage over conventional worm gears is their unique gear tooth geometry.

Intelligent gear tooth geometryThe name CAVEX is well-known and is made up of the Latin word concavus, the worm profile, and convexus, the worm wheel profile. Thanks to the worm teeth with concave flank profile (hollow-flank worm) coupled with convex-shaped worm wheels, CAVEX Worm Gear Units are far superior to compa-rable gear units of the same size. Gear tooth pairing ensures better flank meshing and an extremely low specific gear flank pressure (Hertzian pres-sure). The result: higher torques of up to 360,000 Nm, excellent efficienci-es of up to 95% and a significantly longer lifetime as a result of lower wear.

Complete CAVEX range CAVEX GmbH & Co. KG offers you a complete range of CAVEX Worm Gear Units in 18 sizes from 100 to 360,000 Nm. From single-stage or multi-sta-ge units, in a wide variety of standard versions, as sector-specific solutions or adapted to your specific requirements.

Unique when it comes to efficiency, torque and lifetime

5.6 Backstop

For certain requirements the gear unit is equipped with a mechanical backstop.

Information:

Differentiation is made between two versions:

Version A:

Attention!


The gear unit is a single stage worm gear unit with CAVEX-teething.

yellow

red

white

On worm gear units equipped with ventilators, the ventilator is arranged on the fast running worm shaft of the gear unit and secured against unintentional contact by a ventilator cover. The ventilator sucks in air through the protective grid of the ventilator cover and leads it past the gear casing through the lateral air channels. This cools the air surrounding the gear casing.

Contamination of the ventilator cover and the casing surface especially in the area of the worm drive significantly reduces the cooling effect (See Chapter 10. Maintenance and Service).

As a general rule, elastic couplings should be installed for the drive and output of the gear unit.

If rigid couplings are planned, approval must be obtained from the manufacturer. For the operation of the couplings, the special operating instructions of the couplings must be followed.

For shaft-mounted gear units with hollow shaft in shrink disc version, a shrink disc Type HSD-32 is intended as frictional tension connection between the hollow gear shaft and the machine.

The backstop is installed in the lid on the ventilator side. The backstop is installed oil-proof over an intermediate flange on the gear unit and is integrated in its oil circuit.

Ensure that the air intake on the ventilator cover is not blocked.

During operation, only the pre-determined direction is allowed. This is indicated by a directional arrow on the gear drive side.

5.7 Assembly of IEC-Motors

When installing IEC-Motors, pay attention to the instruction manual of the motor.

6. Assembly

6.1 General assembly information

Information: Follow the instructions in Chapter 3. Safety information.

6.2. Description of the assembly

Attention!

Attention!


When using cleaning agents the relevant regulations and guidelines, for example according to ISO 14001, as well as the laws of the countries and states must be followed. Adhere to the regulations of the manufacturer of the cleaning agents.

Agreement with CAVEX GmbH & Co. KG is necessary to change the rotation direction later on, as this is only possible with high level of technical effort.

In order to avoid damage or destruction of the backstop, attention must be paid to ensure that the motor is not driven against the locked backstop!

Any motor must not be used that exceeds the determined rotation speeds of the gear unit, as this may damage the gear unit.

This version is intended if a later change of rotation direction is expected and no ventilator is required for the gear unit.

The backstop is not integrated in the oil circuit. Separate lubrication is not necessary.

The assembly must be performed such that the gear unit is not distorted during assembly and operation.

The possibility of checking the oil level must be ensured.

Foundations and connection constructions must be made such that no vibrations are transferred from neighbouring components and parts.

A careful alignment to the output and drive side machine must be ensured, so that if necessary, elastic distortions due to the operating forces are taken into consideration if necessary.

Fixing screws or nuts must be tightened with the determined torque. The tightening torque is listed in relevant tables. Screws with the minimum strength class 8.8 shall be used.

If exterior forces influence the gear unit it is useful to prevent dislocation by lateral fixings.

The cooling of the CAVEX gear units must not be influenced. Pay attention to free convection and open air flow during ventilator operation.

To guarantee sufficient lubrication during operation, the installation position stated in the order placement must be adhered to.

Remove corrosion protection paint on the shaft ends and connecting surfaces with cleaning agents.

Protect against burning by hot parts!

Please follow the instruction manual of the part to be assembled.

Mount couplings and similar connecting parts onto the shaft ends and secure them. If they are to be mounted warm, the necessary joining temperatures shall be requested from the manufacturer of the parts to be mounted.

Warming can be performed, if not described otherwise, by induction, with a burner or in the oven.

The gear shaft ends have thread drillings at the front ends with which couplings, disc, gears or similar can be mounted.

For better disassembly we recommend installing a connection for pressurized oil at the shaft end of the machine. To do this, provide a drilled hole that ends at the turned end of the hollow shaft.

The shaft end of the machine must be equipped with a fitted key according to DIN 6885 part 1 Form A and should have a centring device according to DIN 332 Form DS (with thread) on the front end.

The parts to be mounted shall be assembled with help of suitable equipment to prevent damage of the shaft bearing due to axial joining force. The usage of appropriate hoisting devices must be ensured. Ensure that the shaft sealing rings and the surface of the shaft are not dama-ged when mounting the elements.

Any fitting by impact or force is not permissible, as this may damage the rolling bearing, sealing rings and similar parts.

Cleaning agents must not be allowed to penetrate beneath the sealing lips of the shaft sealing rings.

Protection of the cleaned contact surfaces with an appropriate lubricant that prevents fretting corrosion.

Check the hollow and machine shaft for damage to the intakes or edges. If necessary, refinish parts with an appropriate tool and clean them again.

Assembly of the hollow shaft gear unit onto the machine shaft can be performed with an end disc and securing ring, insofar these parts were included in the delivery.

Cover plate End plate (Dismounting disc)

Screw Securing ring

By turning the end plate and using an appropriate screw, the end plate can be used as dismounting disc.

When using cleaning agents, adhere to the relevant regulations and guide-lines, for example according to ISO 14001, as well as the laws of the countries and states. Follow the regulations of the manufacturer of the cleaning agent.

Cleaning agents must not be allowed to penetrate beneath the sealing lips of the shaft sealing rings.

Any lifting by impact or force is not permissible, as this can damage the rolling bearings, securing rings and similar parts.

The hollow shaft may only be drawn against a machine shaft collar on models with torque support, as the bearings would be distorted on other models.

The hollow shaft must be aligned with the machine shaft, so that jamming is prevented.

Remove the corrosion protection coating on the shaft ends and connecting surfaces with a cleaning agent.

Mounting with installed slide bush

Mount drive with nut and threaded spindle. Support is given by the hollow shaft.

The drilling of the hollow shaft and the exterior diameter of the machine shaft must be thoroughly cleaned in the area of the shrink disc position. Both surfaces must be absolutely free of grease.The safety of the torque transfer is highly dependant on this. Contaminated cleaning agents and cloths are inappropriate for degreasing the surfaces.

The hollow shaft must be aligned with the machine shaft, so that jamming is prevented.

On flange gear units, the hollow shaft may not be axially and radically distorted, as the bearings may fail due to excessive load.


Instead of the shown nut and threaded spindle you may also use a hydraulic puller.

The axial securing of the hollow shaft on the machine shaft is performed by the shrink disc connection.

Subsequently, only the interior gliding surfaces of the shrink disc need to be lubricated again.

When using cleaning agents and lubricants, adhere to the relevant regulations and guidelines, for example according to ISO 14001, and the laws of the countries and states. Pay attention to the regulations of the manufacturer of the cleaning agent and the lubricant.

Loosened shrink discs do not need to be taken apart and greased again prior to renewed tensioning.

Shrink discs only need to be disassembled and cleaned when they are dirty.

The exterior surface of the hollow shaft can be greased in the area of the shrink disc location.

Never tighten the tightening screws before the machine shaft is installed, as the hollow shaft will distort.

In order to prevent overload of the individual screws the maximum tightening torque (see Table 6.1) may not be exceeded, the alignment of the front ends is priority. If this alignment is not achieved during tightening, check the tolerance of the insert shaft.

The tightening screws can be tightened in several turns in sequence, until the front surfaces of the exterior and interior rings are aligned.

The tensioning screws are loosened in several turns in sequence.

If the exterior ring does not loosen off the interior ring by itself, unscrew some tightening screws and screw them into the neighbouring dismounting threads.

Easy detensioning is then possible.

Pull off the shrink disc from the hollow shaft.

On gear units with torque support, the support of the torque is achieved by bolts and brackets (see the following drawing). The gear unit must be mounted on the machine shaft without tension. The torque support must be achieved in a manner that the torque support is only tangentially and longitu-dinally stressed when the gear unit is operated. Adhere to the permissible angle for the assembly of the bracket on the torque support.

In the case of misalignment of the machine shaft, attend to the coupling displace-ment on the drive shaft.

Observe the special instruction manuals for the motors and the couplings for the installation of the motors and the couplings.

7. Start up


7.1 Oil filling

Attention!

Attention!


Gear will be supplied without oil filling. Before initial operation, anti-corrosion agent must be discharged and gear must be filled with oil.

When using cleaning agents and lubricants, adhere to the relevant regulations and guidelines, for example according to ISO 14001, as well as the laws of the countries and states. Follow the instructions of the manufacturer of the cleaning agent and lubricants.

Prior to start up, check the oil level. The oil must be filled at least to the middle of the oil level window, as a maximum to the upper edge of the oil level window or up to the lower edge of the oil level opening. The upper locking screw must be replaced with the included ventilation screw.

The oil viscosity to be maintained is listed on the rating plate of every gear unit. If other oils must be used, it is more permissible to use thicker oils than thinner oils. The only oils permissible for use are those listed in the lubricant table in Chapter 10, or according to the lubricant table on the website of CAVEX GmbH & Co. KG.

7.2 Lubrication of bearings

Bearings located above the oil level are equipped with grease filling.

7.3 Installation and assembly parts

7.3.1 Gear units with backstop

Installed or assembled backstops are automatically lubricated.

Attention!In order to avoid damage or destruction of the backstop, ensure that the motor is not driven in the locking direction of the backstop!

Prior to start up, check whether the backstop can be turned in freewheeling without increased effort. The rotational direction arrows on the gear units must be adhered to.

For CAVEX gear units with special additional installations (e.g. pumps, filter-oil cooler, spring-applied brakes, multi-disc clutch or similar) the specific operating instructions must be followed.

The oil quantity stated on the type plate is a reference value. When filling the oil, wait until the oil has become evenly distributed and thus the final oil level is displayed.

7.5 Start Up

8. Operation


Attention!If irregularities occur during operation, the cause must be determined using the fault table (see Chapter 9.). The fault table contains possible faults, their causes and suggestions for solutions. If the cause cannot be determined resp. if it is not possible to repair the unit with own means, we recommend contacting CAVEX GmbH & Co. KG.

Work on the terminals and live parts may generally only be performed by specially trained personnel. Follow the safety instructions.

During operation, check the CAVEX gear unit for:

high operating temperature

different gear unit sounds

possible oil leaks

During start up, ensure that the ventilation screw with cap is installed; if necessary, remove the plastic screw cap or lock screw.

Subsequently, the gear unit is to be operated initially in intermittent duty, meaning operated under normal operating stress for a few minutes, alternating with breaks lasting several times the length of the operating duration. The active periods can be gradually increased up to normal operation, where-by the operating temperature needs to be monitored. Operating temperatures of up to approx. +100C are permissible.

We include a circuit diagram in the terminal box of every E-Motor showing how the motor must be connected. When connecting, ensure that the system voltage corresponds to that stated on the rating plate.

In general, usage of a motor protection switch is recommended for protection against overload or phase failure. The overcurrent relay must be set to the correct rated input current assigned to the respective nominal voltage (see rating plate). Ground or protective wires must be connected with the included ground terminal.

If the motor runs in the wrong rotation direction, 2 phases of the mains connection must be swapped over.
