    摘要: Helical gears are used for a sun gear, planet gears, and an internal gear. Accordingly, when a load, which exceeds a preset torque, is applied to the internal gear, the internal gear is moved in a direction toward an input shaft or a direction toward an output shaft while making rotation in a direction different from that of the sun gear to automatically switch the speed reducing ratio.

    摘要: A ball screw mechanism is equipped with a ball screw shaft formed from a metallic material, a displacement nut inserted over an outer circumferential side of the ball screw shaft, steel balls installed between a first screw groove formed on the ball screw shaft and a second screw groove formed in the displacement nut, and a pair of first and second return members, through which the steel balls are circulated between one end side and another end side of the displacement nut. The first and second return members include main body parts mounted respectively onto one end and another end of the displacement nut, and cylindrical parts that project outwardly with respect to the main body parts. A return passage, through which the steel balls are circulated, is formed inside of the main body parts and the cylindrical parts.

    摘要: A tooth-skipping prevention mechanism includes a block, which is inserted displaceably into a first end block in an electric actuator. A cavity having a semicircular shape in cross section is formed in one end of the block facing toward an outer circumferential side of a drive pulley and recessed toward another end side of the block. In addition, the cavity is arranged at a predetermined distance with respect to an outer circumferential surface of a timing belt that is enmeshed with the drive pulley. When the timing belt is moved in a radial outward direction so as to separate away from the drive pulley, movement of the timing belt is restricted, whereby the enmeshed condition of the timing belt and the drive pulley is maintained.

    摘要: An automatic speed reduction ratio switching apparatus is equipped with a sun gear connected to an input shaft, first and second carriers connected to a feed screw shaft, planetary gears meshed with the sun gear and which are mounted rotatably in the first and second carriers, and an internal gear meshed with the planetary gears and which is capable of movement in an axial direction. A packing member is arranged between the internal gear and the second carrier, for regulating movement in the axial direction of the internal gear, while enabling movement of the internal gear in the axial direction when a thrust force is applied at or above a predetermined value.
