摘要： A combined insulator and conductor assembly is for a bearing disposable between a shaft and a housing and includes an annular insulator disposeable about the bearing outer ring. The insulator is configured to prevent electric current flow between the outer ring and the housing and includes one or more axial mounting tabs. An electrical conductor has an outer radial end, an inner radial end and at least one retainer, the at least one retainer being engageable with the at least one mounting tab to releasably couple the conductor with the insulator. Each retainer includes a radially-extending prong engageable with a separate tab. 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 being conductively engageable with the shaft so as to provide a conductive path between the shaft and the housing.

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 electrical insulator and conductor assembly for a bearing disposable between a shaft and a housing includes an annular insulator disposable about the bearing outer ring and configured to prevent electric current flow between the outer ring and the housing and including a plurality of projections extending axially along and spaced circumferentially about a centerline. A conductor includes a conductive disk with an outer radial end engageable with the housing inner surface, an inner radial end defining a central opening for receiving the shaft and openings each receiving a separate one of the plurality of projections of the insulator such that the disk is axially displaceable relative to the insulator. An annular conductive brush subassembly is coupled with the conductive disk and includes a plurality of electrically conductive fibers contactable with the shaft outer surface so as to provide a conductive path between the shaft and the disk.

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.
