ABSTRACT:
An unlimited sliding ball bearing spline assembly comprises an outer sleeve, a pair of cage halves and a spline shaft. The outer sleeve has a pair of outer peripheral grooves for guiding no-load carrying balls and a pair of inner peripheral grooves for guiding load carrying balls formed longitudinally in outer and inner walls of the outer sleeve, respectively, and alternated with one another in the circumferential direction of the outer sleeve. The grooves of each pair are symmetrically disposed in diametrical opposition to each other. Each of the inner and outer peripheral grooves being provided with semi-circular ball rolling surfaces at both longitudinal sides, respectively. Each of the cage halves 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, grooves for guiding the no-load carrying balls formed at both sides of each of the partition walls, respectively, each of the grooves cooperating with the adjacent one of the ball rolling surfaces formed in each of the outer peripheral grooves, and inner guide members provided with grooves for guiding the load carrying balls in cooperation with the ball rolling surfaces formed in the inner peripheral grooves of the outer sleeve, respectively. Each of the load carrying ball guiding grooves has a longitudinal slit.
