Abstract
A controlled slip torque transmitting apparatus comprises a first substantially cylindrical rotary member which is rigid and has a longitudinal axis of rotation. A somewhat compliant tubular rotary member snugly encircles the first member, the two members being rotatable relatively about that axis. The second member has at least three outwardly extending projections with free ends. An elastic band surrounds the projections so as to exert compressive loads on the body thereby pressing the body against the tubular member at the roots of the lobes so that the clutch has an inherent break away torque when the two members are moved relatively.
Claims8
A controlled slip torque transmitting apparatus comprising
- a substantially cylindrical first rotary member, said member being rigid and having a longitudinal axis of rotation;
- a compliant tubular second rotary member snugly encircling said first member, said members being rotatable relatively about said axis, said second member having at least three projections extending away from said axis and having ends, and
- an elastic hoop surrounding said projections so as to exert compressive loads on said second member so as to press said second member against said first member at the roots of said projections.
A controlled slip torque transmitting apparatus comprising
- a substantially cylindrical first rotary member having a longitudinal axis;
- a compliant tubular second rotary member snugly encircling said first member, said members being rotatable relatively about said axis, said second member having a plurality of radially outwardly extending lobes with free ends which define an imaginary circle concentric to said axis, and
- a flexible resilient hoop, said hoop having an inside diameter less than the diameter of said imaginary circle and encircling said lobes so that the hoop is stressed into a non-circular shape and presses the second member against the first member at the roots of said lobes.
