Abstract: Systems and methods include providing a tolerance ring with a friction enhancement feature on at least one surface of the tolerance ring to increase at least one friction-related property of the tolerance ring. The friction enhancement feature provides the tolerance ring with an increased retention force while providing an optimum radial force that allows a component secured by the tolerance ring to move freely while reducing or altogether preventing axial movement of the component.

Abstract: 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.

Abstract: 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.
