Abstract

PURPOSE: To make circulation of the balls smooth, to simplify the assembling operation and to increase the rigidity of a shaft, by forming projections on the surface of a retainer, attaching end caps to the opposite ends of the retainer, and shaping the spline shaft to have a hexagonal section.
CONSTITUTION: Projections 7 to be fitted in unloaded ball guiding grooves 3 are formed on the outer surface of the retainer 6 where it is held in contact with the inner surface of an outer sleeve 1. End caps 15 are attached to the opposite ends of the outer sleeve 1 so that balls 14 rolled along U-turn grooves 12 of the retainer 6 are guided from the outside. With such an arrangement, positioning of various members can be made accurate by the function of projections 7 and circulation of balls 14 is rendered smooth. At the same time, assembling operation can be simplified by use of end caps 15. Further, machining is also simplfied since ball-spline grooves 21 are formed simply in the outer surface of a shaft having a hexagonal section, and rigidity of the shaft can be kept high since it is not required to reduce the section of ball-spline shaft 20 greatly.
