Abstract
A torque limiting one-way clutch assembly including a bearing housing having a central bore and a number of grooves around the bore, each groove including a recess at one end, a ramp inclined toward the recess, a roller in each of the grooves, a spring assembly mounted on one end of the housing, the spring assembly including a flexible member extending into each of the grooves for bearing the rollers towards the recess, and a torque ring mounted on the outside surface of bearing housing and having an internal diameter smaller than the bearing housing to provide a frictional fit between the torque ring and the outside surface of the bearing housing.
Claims10
A torque limiting one-way clutch assembly for transferring rotary motion from a rotor having a central bore to a shaft extending through said bore, said clutch comprising:
- a bearing housing positioned in said central bore, said housing having an outer cylindrical surface, an axial bore and a number of grooves around said axial bore;
- each groove including a ramp inclined toward one end of said groove;
- a roller in each of said grooves;
- a spring assembly mounted on one end of said housing, said spring assembly including means extending into said grooves for biasing said rollers toward said one end;
- and
- a torque ring mounted on said outside surface of said housing and having an internal diameter smaller than said bearing housing to provide a friction fit between said torque ring and the outside of said bearing housing whereby said bearing housing will slip in said ring when a predetermined torque is applied to said ring.
A one-way clutch assembly for incrementally advancing a shaft in one direction comprising a bearing housing having an axial bore for the shaft,
- said bearing housing including three axially extending grooves equally spaced at predetermined intervals around said bore and three axially extending slots,
- a roller mounted in each groove,
- means on one side of each groove for camming said rollers toward the axis of said bore in said housing,
- a spring assembly mounted on said housing, said spring assembly including a cap for closing one end of said bearing housing, an extension extending into each of said grooves and a flexible tab at the end of each extension for biasing said rollers toward the axis of said bore,
- means extending into said slots for preventing movement between said spring assembly and said bearing housing, and
- means mounted on said bearing housing for retaining said rollers in said grooves.
