Tool for motor reducer assembly machines

摘要

A tool (1) fittable to a spindle (15) of a machine (2) for assembling motor reducers (3); the machine (2) assembling a pinion (5) onto a shaft (4) of the motor reducer (3) by exerting compression, by means of the spindle (15), to force the pinion (5) onto the shaft (4) and form an interference fit. The tool (1) has a tubular body (23) with a cavity (25) for housing the pinion (5); and a number of lock devices (27) housed inside the tubular body (23), and each having a movable stop member (30) which projects inside the cavity (25) and on which rests a shoulder (32) of the pinion (5) to directly discharge the compression exerted by the spindle (15) downstream from the shoulder (32) which separates the toothed end portion (5b) of the pinion (5) from the rest of the pinion (5).
