ータ。[Claims for Utility Model Registration] (1) It has a first groove and a second groove placed back to back, and has an H-shaped cross section, and the opposing inner surface of each groove has an axial direction. a guide rail having a rolling element rolling groove; a first ball screw shaft disposed in the first groove of the guide rail and rotatably supported at both ends via bearings; a second ball screw shaft disposed within the concave groove and rotatably supported at both ends via bearings; A rolling element rolling groove in the axial direction opposite to the rolling element rolling groove of the guide rail is provided on both sides of the square nut having a circulation path for the balls, and a shaft serving as a rolling element passage is provided within the inner wall thickness thereof. through-holes are formed in the respective directions to correspond to the rolling grooves of the rolling elements, and end caps each having a curved groove that communicates the rolling grooves and the through holes are fixed to both front and rear end surfaces of the nut. The nut is provided with a rolling element endless circulation path, and a first one is loosely fitted into each of the first and second grooves of the guide rail.
Each of the second sliders is inserted into the rolling element endless circulation path of the slider, and is inserted into the rolling element rolling groove of the slider and the rolling element rolling groove of the guide rail opposite thereto according to the movement of the slider. a large number of moving rolling elements; an electric motor connected to an end of one of the first and second ball screw shafts; and an electric motor that controls the rotation of one of the screw shafts by the electric motor. The present invention is characterized by comprising a drive device comprising a transmission means for transmitting data to the shaft, and configured such that the first and second sliders and the guide rail move relative to each other in the axial direction at the same time when the drive device is driven. High-speed electric single-axis actuator. (2) The high-speed electrically conductive uniaxial actuator according to claim (1), wherein the transmission means of the drive device is a gear transmission device. (3) The high-speed electrically conductive uniaxial actuator according to claim (1), wherein the transmission means of the drive device is a belt transmission device.
