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.

摘要： It is desired to reduce vibration of a speed reducer. The speed reducer includes a fixed internal gear (3), an input shaft (7) coaxial with the internal gear (3), and an eccentric disk (9) provided on the input shaft (7) and rotatable inside the internal gear (3). A cage (14) is provided at an end of an output shaft (12) coaxial with the input shaft (7) so as to be rotatable between the internal gear (3) and the eccentric disk (9). The cage (14) is formed with pockets (18) which are fewer in number than the internal teeth (4) of the internal gear (3). Rollers (19) are received in the respective pockets (18) such that when the input shaft (7) is rotated once, and the eccentric disk (9) is rotated together with the input shaft, each of the rollers (19) is pushed by the rolling bearing (11) fitted on the eccentric disk (9) and circumferentially moves by a distance equal to the width of one internal tooth (4) while kept in meshing engagement with the internal tooth (4), causing the output shaft to be rotated at a reduced speed. The root radius of the internal gear (3), the radius of the circumcircle of the rolling bearing (11), the circumcircle having a center lying on the center axis of the input shaft (7), and the outer diameter of the rollers (19) are measured beforehand, and determined such that the smallest one of roller gaps (20) defined between the rollers (19) and the tooth bottoms of the internal gear (3) are controlled to reduce vibration.

摘要： PROBLEM TO BE SOLVED: To prevent generation of an edge load due to contact between interference parts of an outside outer tube and an inside outer tube. SOLUTION: A cross-sectional shape in a cross section perpendicular to an axial direction of a side face 7a of each fitting groove 7 for interference of the inside outer tube 4 in contact with a side face 6a of a projection 6 for interference of the outside outer tube 3, is formed into a cross-sectional shape protrusive toward the side face 6a of the projection 6 for interference, whereby an edge load is prevented from occurring even when the interference parts contacts each other by decentering of the outside outer tube 3 and the inside outer tube 4 when a vibration-proofing material 5 is deformed.

摘要： PROBLEM TO BE SOLVED: To provide a link operating device provided with a link mechanism having high rigidity and large portable weight with a compact constitution. SOLUTION: This device has three pairs of link mechanisms 1 to 3 for rotatably connecting end part link members 1a to 3a and 1c to 3c to link hubs 4 and 5 provided on each of an input member 6 and an output member 7 and for rotatably connecting the end part link members 1a to 3a and 1c to 3c of each of an input side and an output side to center link members 1b to 3b. The input side and the output side are made geometrically the same in cross section at a center part of each link mechanisms 1 to 3. Resting mechanisms 11 for resting the output member 7 at an arbitrary position are provided in rotation parts in the rotation pairs of two pairs of link mechanisms 1 to 3 of the rotation pairs of each link mechanism 1 to 3 connected to the input member 6.

摘要： PROBLEM TO BE SOLVED: To provide a one-way clutch having inexpensive construction without using a ball bearing, for actuating sprags with high accuracy. SOLUTION: The one-way clutch includes the plurality of sprags 3 arranged between an outer ring 1 and an inner ring 2 coaxially arranged, in the peripheral direction, a cage 4 for holding the sprags 3 in the peripheral direction, and an elastic member 6 for energizing the sprags 3 in the direction engaging with the inner peripheral face 1a of the outer ring 1 and an outer peripheral face 2a of the inner ring 2. Between the sprags 3, 3 adjacent to each other in the peripheral direction, rollers 14 are arranged for abutting on the inner peripheral face 1a of the outer ring 1 and the outer peripheral face 2a of the inner ring 2. The rollers 14 are held in the peripheral direction by the cage 4, and the sprags 3 and the rollers 14 are held directly or indirectly in the axial direction by the inner-diameter-direction rising portion 10c of the outer ring 1.
