摘要： A pulley device for a tensioner roller or winding roller of a transmission element, providing a pulley, and a bearing. The bearing includes a rotating outer ring mounted to the pulley, a fixed inner ring, and at least one row of rolling elements arranged between the rings. The inner ring of the bearing has at least one end portion protruding axially with respect to the outer ring. The pulley is provided with at least one pulley element that is C-shaped in axial section. One of the at least one pulley elements is provided with a lateral portion extending substantially radially to pass into the immediate vicinity of an outer surface of the axially protruding end portion of the inner ring.

摘要： A pulley device for a tensioner roller or winding roller of a transmission element, having a fixed inner element, a rotating outer element that is mounted to rotate coaxially about the fixed inner element, and an annular protective flange having a substantially radial portion bearing against a front surface of the fixed inner element. The flange includes an annular folded portion extending substantially axially from an outer edge of the flange and passing radially into the immediate vicinity of an axially protruding annular portion of the rotating outer element to form a narrow passage.

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 pulley device for a tensioner roller or winding roller of a transmission element, having a fixed inner element configured to receive a screw, a rotating outer element that is mounted to rotate coaxially about the fixed inner element and is intended to cooperate with the transmission element, and an annular protective flange bearing against a lateral surface of the fixed inner element. The fixed inner element provides a sleeve axially protruding from the lateral surface. The flange provides an inner axial portion mounted securely on an outer surface of the sleeve.

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.
