ABSTRACT:
A light and compact slide-type constant velocity universal joint has a maximum operating angle of 30° or more through optimization of a ball contact angle relative to ball grooves, a ball contact ratio, and a cage offset amount. In the slide-type constant velocity universal joint, a ratio of ball diameter to outer ring outer diameter is 0.21 to 0.25, a ratio of ball pitch diameter to outer ring outer diameter is 0.64 to 0.68, a contact angle of the ball groove is 30° to 35°, a contact ratio of the ball groove is 1.02 to 1.08, and a ratio of cage offset amount to ball pitch diameter is 0.07 to 0.09.
