固定式等速自在継手
Document Type and Number:
Japanese Patent JP5128139
Kind Code:
B2
Abstract:
The present invention provides a fixed-type constant velocity universal joint that can sufficiently interpose a lubricant between a torque transmitting ball and a guide groove, and reduce frictional force. The fixed-type constant velocity universal joint of the present invention includes an outer joint member 1 that is filled with a lubricant and on which a guide groove 1b that extends in an axial direction is formed on a spherical inner circumferential surface 1a, an inner joint member 2 provided on an inner diameter side of the outer joint member 1 and on which a guide groove 2b that extends in the axial direction is formed on a spherical outer circumferential surface 2a, a torque transmitting ball 3 interposed between opposing guide grooves 1b and 2b of the outer joint member I and the inner joint member 2 such as to roll freely, and a cage 4 that holds each ball 3. Numerous miniscule recesses are randomly formed on a surface of the ball 3.
