摘要： A spring clutch is provided for which durability is improved by preventing a clutch spring from breaking due to fatigue. A cylindrical clutch spring made from a wire having a square section is mounted between a pulley and a pulley hub mounted in the pulley. An end of the clutch spring is coupled to the pulley hub. A clutch surface is formed on the inner periphery of the pulley and is formed with a large-diameter recess at a position opposite to the end portion of the clutch spring including the torque transmission end. When the pulley rotates in one direction, the clutch spring expands. At this time, the end portion of the clutch spring including the torque transmission end expands in the large-diameter recess, thus relaxing sharp torque produced in the clutch. This prevents local stress concentration on the clutch spring and breakage of the clutch spring and improves the durability of the clutch.

摘要： A speed reducer includes an internal gear, an input shaft coaxial with the internal gear, and an eccentric disk on the input shaft and rotatable inside the internal gear, and an eccentric disk on the input shaft and rotatable inside the internal gear. A cage at an end of an output shaft, coaxial with the input shaft, and rotatable between the internal gear and the eccentric disk has pockets fewer in number than the internal gear's internal teeth. Rollers are received in the respective pockets such that when the input shaft rotates once, the rollers circumferentially move by a distance equal to one internal tooth width, causing the output shaft to be rotated at a reduced speed. The root radius of the internal gear, the radius of the circumcircle of the rolling bearing, and the outer diameter of the rollers are determined such that roller gaps defined between the rollers and the tooth bottoms of the internal gear are controlled by reduce vibration.

摘要： A linkage system is provided which is equipped with a compact and high-rigidity link mechanism with a large load capacity. The linkage system includes three or more link mechanisms. Each link mechanism consists of a center link member and end link members rotatably coupled to the center link member and to link hubs that are provided to an input member and an output member, respectively. An input side and an output side of a center cross-sectional plane of each link mechanism are geometrically identical. One or more of revolute joints of two or more of the link mechanisms that are coupled to the input member are provided with a stopping mechanism for stopping the output member at a given position.
