SPLINE FITTING STRUCTURE, SLIDING TYPE TRIPOD CONSTANT VELOCITY JOINT, AND BALL-TYPE CONSTANT VELOCITY JOINT

摘要

PROBLEM TO BE SOLVED: To provide a spline fitting structure that can reduce maximum stress applied to splines without impairing connecting power to a shaft in press-fitting to a joint member different in rigidity according to a circumferential position, and to provide a sliding type tripod constant velocity joint and a ball-type constant velocity joint including this structure.;SOLUTION: The spline fitting structure includes the shaft 40 formed with outer splines 42, and the joint member formed with inner splines 23 and press-fitted to the shaft 40 through outer teeth 43 and inner teeth 24. A press-in allowance between respective press-in tooth flanks at pressure contact between the tooth flank of the outer tooth 43 and the tooth flank of the inner tooth 23 is set according to the circumferential position of the joint member.;COPYRIGHT: (C)2010,JPO&INPIT
