Title:
Planet roller type gearbox
Document Type and Number:
Japanese Patent JP6278235
Kind Code:
B2
Abstract:
A first radial bearing (19) and a second radial bearing (20) are respectively disposed in two rows between the outer periphery of a pin (16) and the inner periphery of a corresponding planet roller (13) so as to face each other in the thrust direction. A first inner ring (31) of the first radial bearing is fitted onto a first region (22) of the pin by interference fit. A second inner ring (36) of the second radial bearing is fitted onto a second region (23) of the pin by clearance fit. The second region is closer to a carrier main body (10) than the first region is. An elastic member (50; 100) is interposed between the second radial bearing and the carrier main body. The elastic member elastically presses the second inner ring in a first thrust direction.
