Abstract
PURPOSE: To render the circulation of balls smooth and to increase the rigidity of a shaft, by forming projections on the outer surface of a retainer serving to hold the balls in place, and providing relief sections for preventing contact with the shaft.
CONSTITUTION: The spline shaft 20, fitted on the inner surface of the retainer 6 for holding the balls 14 in place, is axially formed with a ball-spline grooves 21 for holding balls 14 in place together with mating a ball rolling grooves 4 and a small relief sections 22 for preventing that lands 13 of the retainer 6 come into contact with the shaft. By thus positioning various elements by fitting projections 7 into unloaded ball guiding grooves 3 formed in outer sleeve 1, it is prevented that the retainer comes into contact with balls 14, and circulation of balls 14 can be rendered smooth. Further, since the relief sections 22 are provided for preventing contact of the lands 13 with the shaft, machining costs can be rendered low, and rigidity of the shaft can be increased since the section of spline shaft 20 is reduced greatly.
