Abstract: A tolerance ring comprising a metallic band for spring features and a complementary low friction material for frictional considerations is disclosed. The tolerance ring is designed to operate within a precisely controlled torque or axial force band to provide a defined amount of resistance and sliding force control between components that move relative to each other. Isolated portions of the tolerance ring form regions of contact with adjacent ones of the components. Other surfaces of the tolerance ring comprise portions with spring features that have geometry suitable for their spring rate, rather than conforming to mating surfaces of the adjacent components.

Abstract: A tolerance ring is adapted to be deployed between inner and outer components. The tolerance ring includes a generally cylindrical body. The sidewall can include an undeformed portion. The sidewall can further include a plurality of wave structures. The wave structures can protrude radially from the undeformed portion. Some or all wave structures can protrude inwardly or can protrude outwardly. Furthermore, the tolerance ring when placed in an assembly having an inner component and an outer component can have a first torque break-point T1 in a first rotational direction. A torque break point for an assembly comprising an inner component, an outer component, and a tolerance ring is the torque at which slippage occurs.

Abstract: A tolerance ring has a band (16) with outwardly extending corrugated protrusions forming waves (2) which engage a surface (8) of the bore (4) in a housing (5). At one end of the tolerance ring is an outwardly flared guide surface (15a) extending axially from the band (16). The guide surface (15a) acts as an enlarged entrance to the band (16) from a shaft (3) to be mounted in the bore (4) by insertion into the tolerance ring. The use of the guide surface (15a) assists assembly and reduces or eliminates particle production. It is also possible for the corrugated portions to extend inwardly, for the guide surface to be inwardly flared, and for the tolerance ring to be mounted on the shaft prior to insertion in the bore.
