ABSTRACT:
A clutch/bearing assembly includes an outer ring having an inner circumference which is formed with an annular groove and a plurality of juxtaposed inclined ramps. The assembly also include an inner ring having an outer circumference which is formed with an annular groove and a juxtaposed flat. An annular frame formed with a plurality of grips is positioned between the inner and outer rings to hold a plurality of ball bearings in the grooves for rotation of the inner ring relative to the outer ring. Also, an annular casing is positioned between the inner and outer rings to hold a plurality of roller bearings between the flat of the inner ring and a respective inclined ramp on the outer ring. Specifically, the casing allows each roller bearing to separate from its respective inclined ramp and thereby permit a unidirectional rotation of the inner ring relative to the outer ring. On the other hand, a counter-rotation of the inner ring compresses each roller bearing between the flat and an inclined ramp to prevent the counter-rotation of the inner ring relative to the outer ring.
