摘要： A tolerance ring including a substrate, and an overlying layer including at least one of a thermal enhancement layer and a retention layer, the thermal enhancement layer including at least one of i) Vickers hardness 100 W/m·K, the tolerance ring being adapted to provide at least one of a) a thermal transfer between the inner member and the outer member, b) a coefficient of friction between the retention layer and the outer member, μ1, and a coefficient of friction between the substrate and the outer member, μ2, and where μ1>μ2, or c) a retention force, Rf, between the inner member and the outer member, and the assembly has an assembly force, Af, and where Rf>0.1 Af, wherein the tolerance ring includes a plurality of projections protruding radially inward or radially outward.

摘要： 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.

摘要： A tolerance ring has a hollow band with outwardly extending corrugated protrusions forming waves that engage an inner surface of a bore of a housing. At one end of the tolerance ring is an inwardly flared guide surface extending axially and radially from the band. The guide surface acts as a tapered entrance to assist the insertion of a shaft into the hollow band during assembly of the ring into the bore of the housing.

摘要： 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.

摘要： 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.
