Description of AMS.. adapters

AMS.. adapters are used for mounting motors in accordance with IEC standard or NEMA (type C or TC) to SEW-EURODRIVE helical gear units, parallel-shaft helical gear units, helical-bevel gear units, helical-worm gear units, and SPIROPLAN^® right-angle gear units.

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

The designation of the adapter size corresponds to the respective IEC or NEMA motor size.

The torque transmission between motor and gear unit is applied via a positive and puncture-proof claw coupling. Vibrations and shocks occurring during operation are effectively attenuated by an inserted polyurethane girth gear.

An extended adapter is used for certain AMS.. adapter combinations with parallel-shaft helical gear units to avoid collisions with the safety cover. This changes dimension Z5, see dimension sheet Dimensional deviations for certain AMS.. adapter combinations with parallel-shaft helical gear units.

AMS.. adapter with drain hole option (DH)

The drain hole option is only available for the M4 mounting position. It is recommended if moisture or liquids (water) can enter the adapter space due to external influences. The design provides 4 drain holes around the circumference of the spacer ring for this case. Incoming liquids encounter the installed oil flinger, which transports the liquids to the outside due to rotary motion. The medium can run off to the outside through the drainage slope when in idle state.

AMS.. adapter with backstop option (RS)

If the application requires only one permitted direction of rotation, the AMS.. adapter can be configured with an integrated backstop. Backstops with centrifugal lift-off sprags are used. The advantage of this design is that the sprags move around inside the backstop without making contact above a certain speed (lift-off speed). This means the backstops operate wear-free, without losses, maintenance-free and are suited for high speeds.

The backstop is completely integrated in the adapter.
