ABSTRACT:
An unlimited sliding ball bearing spline assembly comprises a cylindrical outer sleeve, a pair of cage halves and a spline shaft. The cylindrical outer sleeve has outer peripheral grooves for guiding no-load carrying balls and inner peripheral grooves for guiding load carrying balls formed longitudinally in outer and inner walls of the outer sleeve, respectively, so that the outer peripheral grooves and the inner peripheral grooves are alternated with each other in the circumferential direction of the outer sleeve, each of the inner and outer peripheral grooves being provided with ball rolling surfaces at both sides, respectively. A pair of cage half includes outer guide members each of which has an inwardly projecting partition wall at a position corresponding to the longitudinal center line of the associated outer peripheral groove of the outer sleeve, ball rolling surfaces for guiding the no-load carrying balls formed at both sides of each of the partition walls, respectively, each of the ball rolling surfaces cooperating with the adjacent one of the ball rolling surfaces formed in each of the outer peripheral grooves of the outer sleeve, and inner guide members provided with slit grooves for guiding the load carrying balls at positions coincident with the ball rolling surfaces formed in the inner peripheral grooves of the outer sleeve, respectively.
