Abstract
A ball bearing/freewheel clutch is provided with an inner race member defining an inner race surface; an outer race member defining an outer race surface concentric with said inner race member; and a raceway between said inner and outer races. The inner and outer race members each have a series of short radially oriented sawtooth inclines on their respective inner and outer race surfaces at right angles to said raceway. A plurality of modified ball bearings are disposed in said raceway between said inner and outer race members, such that said modified ball bearings serve to prevent relative rotation of said inner and outer race members in one direction, and to transmit a torque between said inner and outer races. In the preferred embodiment of the invention, said modified ball bearings have flattened poles which engage said sawtooth inclines in one direction of rotation.
