5 Project Planning for Components on the Input Side5.1 Gear units with IEC or NEMA adapter AM

AM adapters are used for mounting motors built according to the IEC standard or NEMA(design C or TC) onto SEW helical, parallel shaft helical, helical-bevel and helical-wormgear units.

Adapters are available for sizes 63 to 280 for IEC motors. Adapters are available forsizes 56 to 365 for NEMA motors.

The designation of the adapter size corresponds to the relevant IEC or NEMA motorsize.

Torque is transmitted between the motor and the gear unit via a positive and impactresistant dog clutch. Vibrations and shocks occurring during operation are effectivelyattenuated by an inserted polyurethane ring gear.

Backstop AM../RS

If the application requires only one direction of rotation, the AM adapter can be config-ured with a backstop. Backstops with centrifugal lift-off sprags are used. The advantageof this design is that the sprags move around inside the backstop without making contactabove a certain speed (lift-off speed). As a result, the backstops operate with no wearor power loss. They are maintenance-free and can be used at high speeds.

Dimensions:

The backstop is completely integrated in the adapter. This means there is no differencein dimensions between an adapter with or without a backstop (see dimension sheets inthe AM adapter section).

Locking torques:

Specify output direction of rotation when ordering

When you order a gear unit with adapter and backstop, it is necessary to indicate thedirection of rotation for the output shaft/output side. The direction of rotation is givenlooking onto the output shaft/output side of the gear unit. For drives with shaft ends atsides A and B, the direction of rotation must be specified as looking onto side A.

To avoid damage, the direction of rotation of the drive must be checked before startingup the machine.

5.2 AQ adapter for servomotors

An adapter with square flange is used for mounting servomotors onto SEW helical,parallel shaft helical, helical-bevel and helical-worm gear units.

The torque is transmitted via a dog clutch. Possible vibrations and shocks occurringduring operation are effectively attenuated and dissipated by an inserted polyurethanering gear.

Configuration variants

The clutch half on the motor side can be configured either with a clamping ring hub (non-positive, for smooth motor shafts) or a keyway (positive) as required.

• AQH = with clamping ring hub

5 AR adapter with torque limiting couplingProject Planning for Components on the Input Side

5.3 AR adapter with torque limiting coupling

SEW helical, parallel shaft helical, helical-bevel and helical-worm gear units aredesigned with adapter and torque limiting coupling to protect the machine and the driveagainst overload. IEC standard motors of sizes 71 to 180 can be mounted.

The torque is transmitted through a non-positive engagement involving friction ringpads. The slip torque of the coupling can be set using a setting nut and cup springs.Different slip torques are possible depending on the thickness and arrangement of thecup springs. In the event of an overload, the coupling slips and interrupts the power flowbetween motor and gear unit. This prevents damage to the machine and the drive.

Multi-stage gear units with adapter and torque limit-ing coupling

When used in conjunction with multi-stage gear units, the best place to install theadapter and torque limiting coupling is between the two gear units. Please contact SEW-EURODRIVE if required.


The unit sizes of the AR adapter with torque limiting coupling are the same as the AMadapter for IEC motors.

As a result, the gear unit can be selected using the selection tables for AM adapters. Inthis case, substitute the unit designation AM with AR and determine the required sliptorque.

Determining the slip torque

The slip torque should be about 1.5 times the rated torque of the drive. When determin-ing the slip torque, bear in mind the maximum permitted output torque of the gear unitas well as the variations in the slip torque of the coupling (+/-20 %) which are a featureof the design.

When you order a gear unit with adapter and torque limiting coupling, you have tospecify the required slip torque of the coupling.

If no information is given in the order, the unit will be set to the maximum permittedoutput torque of the gear unit.

Torques, slip torques

Speed monitor /W option

We recommend monitoring the speed of the coupling using a speed monitor to avoiduncontrolled slippage of the coupling and the associated wear to the friction ring pads.

The speed of the output end coupling half of the torque limiting coupling is detected in aproximity-type method using a trigger cam and an inductive encoder. The speed monitorcompares the pulses with a defined reference speed. The output relay (NC or NOcontact) trips when the speed drops below the specified speed (overload). The monitoris equipped with a start bypass to suppress error messages during the startup phase.The start bypass can be set within a time window of 0.5 to 15 seconds.

Reference speed, start bypass and switching hysterisis can be set on the speed monitor.

Slip monitor /WS option

In conjunction with VARIBLOC® variable speed gear units (see Variable Speed GearUnits catalog), the speed monitor is replaced by a slip monitor for monitoring the speeddifference between the input and output halves of the coupling.

The signal pick-up depends on the size of the variable speed gear unit and consists oftwo encoders or one encoder and an AC tachogenerator.

Connection The encoder is connected to the monitor using a 2 or 3-core cable (depending on theencoder type).

• Maximum cable length: 500 m with a line cross section of 1.5 mm2

• Standard incoming cable: 3-core / 2 m

• Route the signal lines separately (not in multicore cables) and shield them ifnecessary

• Enclosure: IP40 (terminals IP20)

• Operating voltage: AC 220 V or DC 24 V

• Maximum switching capability of the output relay: 6 A (AC 250 V)

5.4 Adapter with a hydraulic centrifugal coupling AT

SEW helical, parallel shaft helical, helical-bevel and helical-worm gear units can becombined with adapters and hydraulic centrifugal couplings for machines with highinertia starting (e.g. mixers, agitators, etc.). The hydraulic centrifugal coupling protectsthe motor and the driven machine against overload during the startup phase andensures that the machine starts up smoothly. The coupling is installed in a housing toprevent anyone touching it. Cooling of the coupling is ensured via ventilation openingsin the housing. It is possible to mount SEW motor sizes 71 to 180 (0.37 to 22 kW)1).

Preferred speeds are 1400 1/min and 2800 1/min, i.e. 4 or 2-pole attached motors.Please note the increased noise levels of 2-pole drive combinations.

5 Adapter with a hydraulic centrifugal coupling ATProject Planning for Components on the Input Side

Centrifugal coupling

The centrifugal coupling used is a hydrodynamic coupling that operates according to theFöttinger principle. The coupling is filled with oil and consists of a pump wheel (motorside) and a turbine wheel (gear unit side). The pump wheel converts the inputmechanical energy into fluid energy and the turbine wheel converts this energy back intomechanical energy.

The power which the coupling can transmit significantly depends on the speed. As aresult, it is necessary to distinguish between the starting phase and stationary operation.The motor starts up without load during the starting phase until the coupling transmitstorque. The machine is accelerated slowly and smoothly during this phase. Once thestationary operating condition has been reached, a level of operating slip is establishedbetween the motor and the gear unit which is determined by the functional principle ofthe coupling. The motor now only has to supply the load torque demand of the machine,while the coupling helps to absorb any load peaks.

The hydraulic centrifugal coupling is equipped with fusible safety plugs that allow theoperating fluid to be evacuated in the event of excessive temperature (severe overload,blockage). This protects the coupling and the machine from damage.

The adapter with hydraulic centrifugal coupling can be configured with an SEW discbrake if the machine is to be braked in a defined manner. The brake is an electromag-netic disc brake with a DC coil which is released electrically and braked using springforce. As a result, the brake satisfies the safety requirement of braking in the event of apower failure. The braking torque can be varied by means of the type and number ofbrake springs used. The brake can be supplied with DC or AC voltage connection; theequipment needed for controlling the brake and the connection terminals are accommo-dated in a terminal box attached to the adapter.

Motor mounting platform AD.. /P

Belt drives can be set up in a compact configuration using an adjustable motor mountingplatform. The motor mounting platform is arranged in parallel to the input shaft and hastapped holes for IEC standard motors (versions without holes are available on request).The distance from the input shaft can be adjusted using threaded columns.

Selection note (available combi-nations)

See the following table for motors available for the various motor mounting platforms.

If the selected input shaft assembly (with motor mounting platform) cannot be combinedwith the reqired motor, please contact SEW-EURODRIVE.

Thermal limit power for gear units with input shaft assembly

The power values given in the selection tables for gear units with input shaft assembliesare mechanical limit powers. Depending on the mounting position, however, gear unitsmay become thermally overloaded before they reach the mechanical power limit. Formineral oils, corresponding cases are indicated in the selection tables by having themounting position specified (see the column shown in the illustration).

Please contact SEW if the mounting position you require is the same as one of thoseindicated. By considering the actual operating conditions, it will then be possible torecalculate the thermal limit rating based on the specific application. Alternatively, suit-able measures can be taken (e.g. using a synthetic lubricant with higher thermal stabil-ity) to increase the thermal limit rating of the gear unit. The following data are requiredfor the recalculation:
