Abstract
A torque assembly including an inner member; an outer member; a first torque member disposed between the inner member and the outer member; and a second torque member disposed radially exterior or interior to the first torque member; where upon rotation in a first circumferential direction, the first torque member is allowed to generally freely rotate and in a second circumferential direction, the first torque member is radially shifted to impede or prevent rotation, and where the second torque member provides a circumferential slip interface between the inner member and the outer member to allow rotation in the second circumferential direction.
Claims14
A torque assembly comprising:
- an inner member;
- an outer member;
- a first torque member disposed between the inner member and the outer member;
- and
- a second torque member disposed radially exterior to the first torque member;
- wherein upon rotation in a first circumferential direction, the first torque member is allowed to generally freely rotate and in a second circumferential direction, the first torque member is radially shifted to impede or prevent rotation, and wherein the second torque member provides a circumferential slip interface between the inner member and the outer member to allow rotation in the second circumferential direction, wherein the first torque member has a first torque, T1, wherein T1 is the minimum torque at which the first torque member rotates in the first circumferential direction, wherein the first torque member has a second torque, T2, wherein T2 is the minimum torque at which the first torque member rotates in the second circumferential direction, wherein the second torque member has a third torque, T3, wherein T3 is the minimum torque at which the second torque member rotates in the second circumferential direction, and wherein T1<T3<T2.
A torque assembly comprising:
- an inner member comprising a shaft;
- an outer member comprising a housing;
- a first torque member comprising a bearing disposed between the inner member and the outer member;
- and
- a second torque member disposed radially exterior to the first torque member;
- wherein upon rotation in a first circumferential direction, the first torque member is allowed to generally freely rotate and in a second circumferential direction, the first torque member is radially shifted to impede or prevent rotation, and wherein the second torque member provides a circumferential slip interface between the inner member and the outer member to allow rotation in the second circumferential direction, wherein the first torque member has a first torque, T1, wherein T1 is the minimum torque at which the first torque member rotates in the first circumferential direction, wherein the first torque member has a second torque, T2, wherein T2 is the minimum torque at which the first torque member rotates in the second circumferential direction, wherein the second torque member has a third torque, T3, wherein T3 is the minimum torque at which the second torque member rotates in the second circumferential direction, and wherein T1 <T3 <T2.
