Backstopping Clutch With Torque Transmission Through Radial Surface of Outer Race

摘要

A backstopping clutch is provided having improved torque transmission. The clutch includes a housing, an inner race disposed within the housing and configured for coupling to a driven member for rotation about a rotational axis and an outer race disposed with the housing radially outwardly of the inner race. A plurality of torque transmission members are disposed between the inner and outer races such that the inner race is freely rotatable relative to the outer race in a first rotational direction, but the torque transmission members engage the inner and outer races and inhibit rotation of the inner race relative to the outer race in a second rotational direction. Friction discs are coupled to a radially inner surface of the housing and a radially outer surface of the outer race and configured to engage one another to transmit a braking torque.

1. A backstopping clutch, comprising:
a housing; an inner race disposed within said housing and configured for coupling to a driven member for rotation about a rotational axis; an outer race disposed with said housing radially outwardly of said inner race; a plurality of torque transmission members disposed between said inner and outer races, said inner race freely rotatable relative to said outer race in a first rotational direction, said torque transmission members configured to engage said inner and outer races and inhibit rotation of said inner race relative to said outer race in a second rotational direction; a first friction disc coupled to a radially inner surface of said housing; and, a second friction disc coupled to a radially outer surface of said outer race and configured to engage said first friction disc a first plurality of roller bearings engaging a first axial end of said outer race; and, a second plurality of roller bearings engaging one of a radially inner surface and said radially outer surface of said outer race.
