UNIAXIAL ACTUATOR AND UNIAXIAL ACTUATOR DEVICE INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a uniaxial actuator which supports an input shaft with a compact structure while reducing a tensile force of a timing belt which is received by the input shaft of the uniaxial actuator.SOLUTION: A uniaxial actuator device 1 includes: a uniaxial actuator bracket 18 to which a uniaxial actuator body 10 is attached; a driven pulley 42 attached to a screw shaft (an input shaft) 21 of the uniaxial actuator body 10 which protrudes from the uniaxial actuator bracket 18 to the timing belt mechanism 40 side; and an angular contact ball bearing 45 disposed between the driven pulley 42 and the uniaxial actuator bracket 18. The driven pulley 42 is rotatably supported by the uniaxial actuator bracket 18 through the rolling bearing 45.SELECTED DRAWING: Figure 1
