ABSTRACT:
A speed reducer construction for use with a drive motor which has a drive motor housing and a drive motor shaft which extends out of the housing comprises a reducer housing which is adapted to be coupled to the drive motor housing and encloses a portion of the motor drive shaft. The motor drive shaft is advantageously journalled in the reducer housing and it carries a worm made of a Nylatron material which is rotatable therewith. An output shaft extends transversely to the drive shaft and is journalled in the reducer housing and it carries a sleeve which is keyed thereto for rotation therewith. A gear is freely rotatable on the sleeve alongside a collar portion of the sleeve and is in meshing engagement with the worm. The drive of the motor through the worm to the gear and the output shaft is regulatable by a clutching device including a clutch spring which is biased against an end of the gear with a biasing force which is regulated by a torque adjusting wheel which is threaded on the sleeve. The arrangement permits some slippage between the drive gear and the drive shaft during overload. The worm shaft is adjustable relative to the gear by means of an adjusting knob which may be fitted into an opening in the reducer housing so as to become engaged with the motor drive shaft.
