摘要 |
A motor, a ball screw shaft, etc. are accommodated within a frame that forms an outer frame. Direct-acting guides are provided on both sides of a groove-shaped opening defined in the frame. The ball screw shaft is centrally disposed within the frame. A table slides along the direct-acting guides under the action of rotation of the ball screw shaft. The ball screw shaft has ball-screw splines formed over its entire length and both ends thereof supported by the motor and a bearing. The center of rotation of the ball screw shaft is brought into alignment with the centers of rotation of the motor and the bearing by balls inserted into the ball-screw splines.
