    IPC: F16D1/08

    Abstract: An assembly including an outer member; an inner member; and a tolerance ring disposed between the inner member and the outer member, wherein the tolerance ring is a split ring comprising opposing edges, where the edges engaged with at one of the inner member or the outer member so as to prevent or restrict movement between the tolerance ring and at least one of the inner member or the outer member, or where the tolerance ring is deformed as installed between the inner member and the outer member and forms at least one buckled region in the tolerance ring due to an interference fit between the inner member and the outer member, where in an uninstalled state, the buckled region is absent.

    IPC: F16D43/21

    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.

    Abstract: A tolerance ring can be disposed between an inner component and an outer component, the inner and outer components defining stepped sidewalls. In an embodiment, a preassembly can include an outer component defining a bore having a stepped inner sidewall, an inner component having a stepped outer sidewall, and a tolerance ring adapted to be disposed between the inner component and the bore. In an embodiment, an assembly can include an outer component defining a bore having a stepped inner sidewall, an inner component having a stepped outer sidewall, and a tolerance ring disposed between the inner component and the bore. In an embodiment, a hard disk drive preassembly can include an actuator arm defining a bore having a stepped inner sidewall, a pivot having a stepped outer sidewall, and a tolerance ring adapted to be disposed between the pivot and the bore.

    IPC: F16D7/02

    Abstract: A tolerance ring including a sidewall including a plurality of radially extending projections on a first radial surface and an unformed region on a second radial surface opposite the first radial surface, where the tolerance ring provides a first break-away torque, τ1, defined as the breakaway torque between the tolerance ring projections and an inner component or an outer component, where the tolerance ring provides a second break-away torque, τ2, defined as the breakaway torque between the unformed region and the other of the inner component or the outer component, and wherein 1.1 τ2≤τ1.
