ABSTRACT:
A composite motion guide unit comprises a single shaft having ball screw groove and a ball spline groove in an outer peripheral surface thereof in an overlapped manner, a nut mounted on the shaft through a number of balls, and a spline outer sleeve mounted on the shaft through a number of balls. The composite motion guide unit is incorporated in a housing, as a composite motion guide device, in which the nut and the spline outer sleeve are rotatably mounted through respective pairs of support bearings incorporating a number of balls, and the nut and said spline outer sleeve are independently driven through power transmission members. The balls interposed between the nut and the shaft are pre-loaded in an axial direction thereof, balls incorporated in the support bearing in support of the nut are pre-loaded, and balls interposed between the spline outer sleeve and the shaft are pre-loaded in a substantially rotating direction thereof.
