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 (200) including a tolerance ring sidewall (404) including a plurality of waves (or bridges) (452) extending at least one of radially inward or outward and having first (416) and second end portions (420) terminating at first (417) and second ends (421), respectively, where the tolerance ring has a first radius of curvature Ri, measured at a point bisecting a circumferential length, LC, of the tolerance ring sidewall, and a second radius of curvature, R2, measured along one of the first and second end portions of the tolerance ring sidewall, and wherein at least one of: 1) Ri is greater than R2, or 2) wherein Ri is negative and R2 is positive.

Abstract: Systems and methods include providing a tolerance ring in an electric drive motor assembly having a housing and a stator disposed within the housing. The tolerance ring is disposed within the housing and retains or secures the stator within the housing and control movement of the stator within the housing. The tolerance ring includes an annular ring-shaped substrate formed from a metallic material and a plurality of projections protruding radially inward from an inner surface of the substrate or radially outward from an outer surface of the substrate. The tolerance ring optionally includes one or more cooling features formed in the substrate and configured to promote cooling between a fluid disposed in the housing and the stator.

Abstract: An electric motor or generator assembly includes a stator, a housing, and an annular member fit between the stator and the housing, where the annular member is radially compressed so as to exert a radial force outward onto the housing and inward onto the stator to maintain a positional relationship therebetween.
