Torque limiting tolerance ring
A torque limiting tolerance ring that is configured to be installed between an inner component and an outer component is disclosed. The torque limiting tolerance ring can include a generally cylindrical body that can have a sidewall. The sidewall can include an unformed section and a plurality of projections can extend from the unformed section of the sidewall. The projections can be configured to engage the inner component or the outer component. During use, the torque limiting tolerance ring can move from an engaged configuration, in which the inner component is statically coupled to the outer component, to a disengaged configuration, in which the inner component is disengaged from the outer component.
1. An assembly, comprising:
an inner component;
an outer component at least partially surrounding the inner component, wherein the inner component comprises an outer cylindrical surface formed with a plurality of voids or the outer component comprises an inner cylindrical surface formed with a plurality of voids; and
a torque limiting tolerance ring installed between the inner component and the outer component, the torque limiting tolerance ring comprising:
a generally cylindrical body having a sidewall, wherein the sidewall includes:
an unformed section;
a plurality of projections extending radially inward or outward from the unformed section of the sidewall toward the voids formed in the inner component or toward the voids formed on the outer component,
wherein the torque limiting tolerance ring is rotatable between an engaged configuration, in which the inner component is coupled to the outer component, and a disengaged configuration, in which the inner component is disengaged from the outer component, wherein the plurality of projections engage the inner or outer cylindrical surface of the outer or inner component in the engaged configuration, and wherein the plurality of projections extend at least partially into the voids formed in the inner or outer component in the disengaged configuration.
2. The assembly according to claim 1 , wherein each void includes a bore extending radially inward or radially outward with respect to a longitudinal axis.
3. The assembly according to claim 1 , wherein each void comprises a circumferential width, W D , measured at a widest portion of each void, and each projection comprises a circumferential width, W P , measured at a widest portion of each projection the projection and W P ≦W D .
4. The assembly according to claim 1 , wherein each void comprises a circumferential width, W D , measured at a widest portion of each void, and each projection comprises a circumferential width, W P , measured at a widest portion of each projection and W P ≧W D .
5. The assembly according to claim 1 , wherein the torque limiting tolerance ring comprises a metal.
6. The assembly according to claim 1 , wherein the projections are equally spaced apart around a circumference of the torque limiting tolerance ring.
7. The assembly according to claim 1 , wherein each projection has a rounded cross-sectional shape as viewed along a cross-section perpendicular to an axis of rotation of the assembly.
8. The assembly according to claim 1 , wherein each of the plurality of voids does not fully penetrate the inner component or outer component.
