<p>PROBLEM TO BE SOLVED: To transmit the rotation of a ball spline shaft to a rotating member such as ball screw shaft provided on a table by rotatably supporting a slide on the table through a roller bearing, and arranging the slider on the spline shaft in such a manner as to be slidable and integrally rotatable. SOLUTION: A ball spline shaft 15 rotatably mounted on a bed is rotated, and a slider 24 is also rotated to rotate another part through a rotating member provided on the slider 24. Since the slider 24 is rotatably supported through a roller bearing 30 by an outer ring 25 fixed to the table, the slider 24 is relatively moved in axial direction or on the plane to the ball spline shaft 15 according to the movement of the table. The rotating movement can be transmitted to the rotating member relatively moved in the axial direction by the slider 24 and the roller bearing 30, and the structure itself can be made compact.</p> |
