  • Tapered roller one-way clutch
    Patent number: 5653320
    Abstract: A tapered roller one-way clutch for use with vertical shafts having an outside surface comprising a clutch housing having a bore extending through the housing and the vertical shaft rotatably inserted into the bore, a plurality of roller pockets are formed on the inside surface of the bore, the roller pockets extend axially along the inside surface of the bore from near the top of the bore to near the bottom of the bore and are spaced equally around a circumference of the bore, each roller pocket further comprises a roller landing tapering away from the axis of the bore to a roller shoulder formed along a diameter of the bore, a tapered roller having an outer surface is rotatably held in each roller pocket by the shaft outside surface, the roller landing is inclined to the axis of the bore to allow the outer roller surface to roll along the shaft outside surface and hold the tapered roller at an angle to maximize surface contact, the roller landing having an arcuate or helical shape from the roller shoulder t
