PLANETARY GEAR PINION SHAFT SUPPORT STRUCTURE

摘要

The disclosed pinion shaft support structure allows attachment of pinion shafts in a phase-aligned state by one simple process not requiring special equipment or a staking step. The pinion shaft support structure is provided with pinion gears, pinion shafts for supporting the pinion gears, and a carrier with multiple shaft support holes for rotatably supporting the pinion shafts, wherein the pinion shafts are supported by the shaft support holes. The pinion shaft support structure is further provided with stepped sections formed on the end surfaces of the pinion shafts, and retaining washers capable of locking the stepped sections by being attached to the carrier. The retaining washers attached to the carrier can be locked in an arrangement in which the outer rim of a washers faces the stepped section of a pinion shaft inserted into a shaft support hole, and this allows positioning in the direction of rotation (phase alignment) of the multiple pinion shafts.
