ABSTRACT:
A rotary drive assembly wherein a shaft is retained within a pinion against axial displacement therefrom by a projection on the shaft received in an annular recess in the pinion. The projection is forcibly urged axially from one end of the pinion bore therethrough into alignment with the recess whereupon the enlargement effectively locks the shaft to the pinion. Bearing portions may be provided on the shaft to be disposed outwardly of the opposite sides of the pinion for journaling the assembled shaft and pinion in suitable bearings. One bearing portion may be larger than the pinion bore so as to limit the relative movement therebetween. The bearing adapted to journal the larger bearing portion of the shaft is arranged to pass the shaft enlargement freely therethrough during assembly of the shaft to the pinion.
