摘要： A pulley device for a tensioner roller or winding roller of a transmission element, having a pulley, a bearing, and an annular protective flange. The flange provides a first radial portion of small diameter, the first radial portion bearing against a fixed inner ring of the bearing, a second radial portion of large diameter, and a substantially axial intermediate portion connecting the first and second radial portions. The intermediate portion forms a circumferential trough, the bottom of which is offset radially towards the inside of the pulley device compared with the outer edge of the fixed inner ring.

摘要： The pulley device for a tensioner roller or an idler roller of a transmission element having a pulley and a bearing. The bearing is provided with a rotating external ring mounted to the pulley, and with a fixed internal ring, a radial space being defined between the rings, with rear sealing means and front sealing means closing the radial space on each axial side, and with at least one row of rotating elements arranged in the radial space. The fixed internal ring is provided on its rear side with a circumferential groove for collecting pollution which is machined on an external surface of the ring, the circumferential groove being offset axially in relation to the rear sealing means outside the radial space.

摘要： A pulley device comprising a pulley and a bearing. The pulley has at least one “C-shaped” pulley part having an inner portion mounted on the bearing, an outer portion having an outer cylindrical surface dedicated to interact with a belt or a chain, and an intermediate portion extending substantially radially between axial ends of inner and outer portions on one axial side of pulley device. The outer cylindrical surface of outer ring is provided with at least one recess having in cross-section, a concave internal profile. The pulley part is provided with at least one protruding portion which inwardly extends beyond the inner cylindrical surface of inner portion. The protruding portion is received in a corresponding recess of outer ring so as to block the pulley part with respect to the outer ring in both axial directions.

摘要： A clutch release bearing for a motor vehicle includes a thrust element having an axial axis, a guide element supporting said thrust element, and a self-aligning sleeve including an annular body and a plurality of radial ribs extending towards the guide element from the body with a free end of each of the ribs radially contacting the guide element. The guide element includes angular retaining members for limiting angular movement of at least one radial rib of the plurality of radial ribs, which members may be integrally formed with the guide element or formed as separate elements attached to the guide element.

摘要： A combined electrical insulator and conductor assembly for a bearing disposable between a shaft and a housing. An annular insulator is disposeable about the bearing and configured to prevent electric current flow between an outer ring and the housing. An electrical conductor has retainer(s) releasably engaged with the insulator so as to couple the conductor with the bearing, an outer radial end and an inner radial end. The conductor outer radial end, or/and a portion of the conductor between the outer and inner ends, is conductively engageable with the housing and the conductor inner radial end is conductively engageable with the shaft so as to provide an electrically conductive path between the shaft and the housing. Preferably, the conductor includes a conductive disk having arcuate retainer clips engageable with an insulator groove of the insulator and a brush subassembly including conductive fibers engaged with the shaft outer surface.

摘要： A combined insulator and conductor assembly for a bearing disposable between a shaft and a housing includes an annular insulator disposeable about the bearing outer ring and having inner and outer circumferential surfaces and formed of an electrically insulative material or having one or more insulative layers to prevent electric current flow between the outer ring and the housing. A conductive carrier includes a cylindrical portion having an inner surface disposed about the insulator outer surface and an outer surface disposeable against the housing inner surface and a disk portion extending radially inwardly from the cylindrical portion having an inner radial end spaced outwardly from the shaft. An annular conductive brush subassembly is coupled with the carrier disk portion and includes a plurality of electrically conductive fibers contactable with the shaft outer surface to provide a conductive path between the shaft and the carrier, and thereafter to the housing.
