ABSTRACT:
An unlimited sliding ball spline comprising a spline bearing consisting of an outer cylinder, a ball retainer provided on the inner side of the outer cylinder, and a plurality of balls held by the ball retainer in a plurality of unlimited passages formed on the inner side of the outer cylinder, in such a manner that the balls can be rolled in the unlimited passages; and a spline shaft supported on the plural balls in the spline bearing. The ball spline is capable of making linear, axial reciprocating movements and torque-transmitting rotational movements separately or simultaneously. Especially, the outer cylinder of the spline bearing is provided on a substantially intermediate poriton of an outer surface thereof with a circumferential member used to combine the spline bearing with a third member, such as a housing, or transmit and receive power to and from a third member.
