Abstract

PURPOSE: To obtain a planetary geared reduction mechanism which is compact and easy to assemble by putting a common ring gear in mesh with multiple-staged planetary gears.
CONSTITUTION: A drive shaft 12 is rotated by reciprocating a piston 21 over a bent axial part 11 of a hydraulic motor. Around the drive shaft 12 are lining up a sun gear 28 at the first stage, a planetary gear 29, a sun gear 35 at the third stage from a carrier 30, a planetary gear 36, multiple-staged planetary gears up to a carrier 37, the sun gear 28 at the first stage is incorporated with the drive shaft 12, and the carrier 37 at the final stage is linked with a mechanical frame 16 at the trunk part on the fixing side. A ring gear 31 plays a common role to the planetary gears at each stage, which offers the output rotation of the reduction mechanism. The commonage of a ring gear 31 facilitates overall compact centering. In concurrence of disengaging an edge plate 43 with disengaging the mesh of the sun gear 28 out of the planetary gear 29, the ring gear 31 on the output side can be rotated irrespectively of the drive shaft 12
