Title:
SUPPORT PART STRUCTURE OF TRANSMISSION GEAR, SPEED REDUCER, AND ROTARY DEVICE
Document Type and Number:
Japanese Patent JP2020200913
Kind Code:
A
Abstract:
To provide a support part structure of a transmission gear which can inhibit generation of noise when power is transmitted, and to provide a speed reducer and a rotary device.SOLUTION: A support part structure of a transmission gear comprises a transmission gear 40, a support block, bearings 42A, 42B, and a displacement restriction part. The transmission gear 40 includes: a shaft part 40a which may rotate around an axis; a first gear part 40b which is formed at the shaft part 40a and engages with an input gear 33; and a second gear part 40c which is formed at a position spaced apart from the first gear part 40b of the shaft part 40a in an axial direction and engages with an output gear. The support block supports the transmission gear 40. The bearings 42A, 42B enable the support block to rotatably support the transmission gear 40. The displacement restriction part restricts axial displacement of the transmission gear 40.SELECTED DRAWING: Figure 1
