摘要： A wave plug of a wave generator of a wave gear device includes: a metallic outer hollow body with an elliptical wave plug outer circumferential surface formed thereon; a metallic inner hollow body with a wave plug inner circumferential surface formed thereon; and an intermediate hollow body sandwiched between the outer hollow body and the inner hollow body. The intermediate hollow body includes CFRP layers. It is possible to implement a light wave plug in which a big hollow portion can be formed while assuring a required rigidity. Using the wave plug makes it possible to implement a light wave gear device which allows jumping to occur at a high load torque and which includes a big hollow portion.

摘要： A concentric double axis actuator has a two-stage cross roller bearing, and a preceding-stage actuator and a subsequent-stage actuator which are linked in tandem. The front end of a subsequent stage rotary output shaft of the subsequent actuator, said subsequent stage rotary output shaft passing through a hollow section of the preceding-stage actuator and projecting forward, is linked and fixed to an inner ring of the two-stage cross roller bearing, and the inner ring functions as a subsequent-stage rotary output member. The output rotary side of the preceding-stage actuator is linked to an middle ring of the two-stage cross roller bearing, which functions as a preceding-stage rotary output member. The rotary output element of each stage is supported by the two-stage cross roller bearing, and surface oscillations of the rotary output member of each stage can be minimized, and the moment stiffness of the members can be increased.

摘要： A retainer of a crossed roller bearing has a retainer body plate of rectangular profile corresponding to a rectangular cross-section of a race. Rectangular side surfaces on either side of the retainer body plate are inclined planes that slant in a direction of approaching one another from one corner to another corner along a diagonal line of the surfaces, and extend towards a bearing center in a state of having been installed in the race. Recesses for accumulating grease are formed in center portions of the rectangular side surfaces, the recesses communicating via a through-hole. The rectangular side surfaces are in linear contact with the circular external circumferential surfaces of adjacent rollers and hold the rollers at a fixed spacing. There is obtained a retainer for an uncomplicatedly configured crossed roller bearing that allows adjacent rollers to be held at a fixed spacing and is provided with a grease accumulator.

摘要： There is performed a treatment including a grinding working step of grinding at least a portion of a rolling surface and a sliding surface of a motion guide device using a rolling member by a grinding working using a grinding stone, and a surface treating step of effecting a peening treatment to a friction surface formed by the grinding working to render a defect on the friction surface caused by the grinding working harmless. By manufacturing a motion guide device through such treating steps, a defect such as flaw generated on the friction surface is made harmless, the fatigue strength, sliding performance and lifetime of the device can be improved. Even in a travelling distance test, a travelling distance largely over a calculated lifetime could be achieved.

摘要： A cross-roller bearing with plug, which has the high stiffness enough to allow the cross-roller bearing to turn with causing no jar or wobble, and also the production process to realize the cross-roller bearing with plug with ease and accuracy. With the cross-roller bearing with plug, more than one roller fills the space between the outside and inside races through a loading bore cut in any one of the races, and then a plug fits into the loading bore. The plug experiences cutting on its outside surface at the same time with the cutting of the circular outside surface of the outside race at once. The inside surface of the plug is also worked together with the cutting of the raceway surface around the inside circular surface of the outside race at a time.
