  • Patent number: 11761495
    Abstract: The present invention aims at providing a cam clutch that prevents cams from unwanted wedging and enables smooth operation including the switching between operation modes without involving an increase in size or number of components and with a simple structure. The cam clutch according to the present invention uses first cams and second cams having different engaging directions as sprags for transmitting and interrupting torque between an inner race and an outer race. A cam interlock mechanism tilts the second cams to a disengaging direction with a tilting motion of the first cams toward an engaging direction, to separate engaging surfaces of the second cams from raceways of the inner race and/or the outer race.

  • Patent number: 9004449
    Abstract: A conical rotary valve for chromatographic applications is provided, including a valve stator, a valve rotor, a drive adaptor and a pair of stoppers each mounted to the stator. The drive adaptor is rotatable and coupled to the valve rotor for transmitting a rotating force thereto. The drive adaptor has a body and a pair of radial arms projecting from the body radially outward from the axis of rotation on opposite sides thereof. Each of the pair of radial arms is movable along a respective arcuate travelling course with respect to the stator. The stoppers are each positioned to obstruct one of the radial arms at an end of the corresponding travelling course. The stoppers are positioned to simultaneously engage the radial arms, thereby balancing the reaction forces created within the valve when the radial arms reach the ends of their travelling courses.

  • Patent number: 8967869
    Abstract: Particles, embedded into a sliding layer, have a coating, within which a lubricant, e.g., a liquid, is contained. A component with the sliding layer provides a sliding surface that can be used as a backup bearing to ensure emergency operating properties, for example, of a shaft that is mounted in a main bearing. When the shaft strikes the bearing surface, the coating of the particles that are exposed on the bearing surface are destroyed and the lubricant can exit. Advantageously, the sliding properties of the sliding surface are thereby improved.

  • Patent number: 8967870
    Abstract: A high-precision slide bearing includes a substrate of sintered metal and a synthetic resin layer. The bearing can be used for rotary shafts in compressors of room air-conditioners or in transmissions of motor vehicles and construction machines to support relatively large radial and axial loads. The resin layer is integrally superposed on the radially inner surface of the sintered metal substrate of the slide bearing, which is a cylindrical member. The resin layer is made of a resin composition of an aromatic polyetherketone resin containing a fibrous filler. The fibrous filler is made up of fibers dispersed in the resin layer and oriented such that their length directions intersect the rotational direction of the bearing at angles of 45 to 90 degrees. The resin layer has a thickness of 0.1 to 0.7 mm.

  • Publication number: 20150043847
    Abstract: A bearing assembly for rotatively holding a shaft with respect to a support member and comprises: a bearing, with a rotatable ring and a fixed outer ring to be immobilized within a housing of said support member. An encoder washer is fast in rotation with the rotating ring. At least one sensor is adapted to detect at least one rotation parameter of the encoder washer and a sensor body holds this sensor. An annular flange is used for mounting said sensor body with respect to the fixed outer ring. The annular flange has a first skirt and a second skirt which define, between them and a bottom wall of the flange, an annular recess for accommodating at least a part of the sensor body. In mounted configuration of the bearing assembly, the first and second skirts extend respectively towards the rotatable and fixed rings.
