Title:
差動減速機及び差動減速機の製造方法
Document Type and Number:
Japanese Patent JP7266492
Kind Code:
B2
Abstract:
To provide a differential speed reducer capable of increasing rigidity and a manufacturing method for a differential speed reducer.SOLUTION: In a differential speed reducer comprising an internal gear, a first carrier member 4a, and a plurality of pins 25 integrally coupled to the first carrier member 4a, a pin hole 27 formed in the first carrier member 4a comprises a first press-fit part 31 into which the pin 25 is press-fitted when viewed from an input side in a central axis direction, and a relief part 30 having an inner peripheral surface that is not in contact with the pin 25. Since the first press-fit part 31 is formed at a position closer to an external gear than the relief part 30, the rigidity of the pin can be increased and the rigidity of the differential speed reducer can also be increased.SELECTED DRAWING: Figure 3
