ABSTRACT:
A two-stage speed reducer including a planocentric gear arrangement which has a rotatable output ring gear and a planet gear mounted within the ring gear for orbital movement. The teeth on the ring gear and the planet gear are tapered to permit axial adjustment of the planet gear with respect to the ring gear and thereby eliminate backlash between the two. Adjustment means is provided to permit axial adjustment of the planet gear with respect to the ring gear. After a period of use of the speed reducer, the planet gear may be readjusted axially relative to the ring gear to compensate for backlash created between the teeth of the planet gear and ring gear due to wear.
