Abstract:
A pulley unit including:an inner shaft; an outer ring disposed concentrically about said inner shaft to define an annular space therebetween; a one-way clutch having a plurality of rollers disposed in the annular space between said inner shaft and said outer ring, and a clutch inner race outer surface which has a non-circular configuration which defines maximum and minimum clutch inner race radii, and which contacts said plurality of rollers and rotates with said inner shaft; first and second rolling bearings in said annular space on first and second opposing axial sides of said one-way clutch; and said one-way clutch including a cage defining rolling regions of the plurality of rollers, said cage having a cage inner circumferential surface for non-rotatably engaging said clutch inner race outer surface, said cage inner circumferential surface defining maximum and minimum cage inner radii, said minimum cage inner radius being not less than said minimum clutch inner race radius, and said minimum cage inner radius being less than an outer radius of a first bearing inner race surface of said first roller bearing.
