Abstract

PURPOSE:To obtain the same function as a hydraulic and neumatic cylinder with a simple structure by a method wherein a rotation of a ball screw shaft is blocked by a normal and reverse rotation of a rotor at a ball spline shaft part in order to make the ball screw shaft have a rectilinear motion. CONSTITUTION:A ball screw shaft 5 is solid with a ball spline shaft part 4 fitted in a center space of a hollow motor shaft 2 which has a ball screw nut 1. The ball screw shaft 5 is so supported as not to rotate by a ball spline outer cylinder 8 fixed to an outer shell 17 through the ball screw nut 1 and a ball spline bearing housing 6. According to a normal and reverse rotation of a rotor 3 fixed to the motor shaft 2, the ball screw shaft 5 makes right and left rectilinear motion.

、空圧シリンダーと同様の機能を果す事が出ｊｌｅる。In order to eliminate the above-mentioned drawbacks, the present invention has been designed to solve the above-mentioned drawbacks by using electrical control.To explain this with reference to the drawings, a ball spline shaft part is incorporated in the central space of a hollow motor shaft 2 holding a ball screw nut 1. A ball screw 1115 integrated with the rotor 3 is connected to the rotor 3 fixed to the ball spline outward 8 motor 1 which is fixed to the outer shell cylinder 7 via the ball screw nut 1 and the ball spline bearing housing 6. With the positive and shameful movements, linear movement can be made from side to side (since it is made of one piece, the ball screw shaft 5 can perform the same function as a hydraulic or pneumatic cylinder).

従って本発明は上記の如き借造によりボールねじ輔５に
