Title:
JOINT CROSS-TYPE UNIVERSAL JOINT YOKE
Document Type and Number:
WIPO Patent Application WO/2015/174433
Kind Code:
A1
Abstract:
A joint cross-type universal joint yoke in which the formation directions of a through-hole (17a) and a screw hole (18a) are inclined relative to the central axis of circular holes (19a, 19a) formed in a pair of engagement arm parts (12, 12). In addition, by tightening a bolt (32) and by first and second flange parts (14a, 15a) approaching one another, a force is made to act on the coupling arm parts (12, 12) in a direction that is inclined relative to the central axis of the circular holes (19a, 19a) and in the direction in which the flange parts approach one another. Thus, cap bearings (29) incorporated in the circular holes (19a, 19a) are pressed onto the end parts of shaft parts (28a) that constitute a joint cross (27). Thus, it is possible to suppress rattling between the bearings incorporated inside the circular holes and the end parts of the shaft parts of the joint cross, said end parts being rotatably supported by the bearings.
