Abstract: A tolerance ring (10) for providing an interference fit between inner and outer components (36, 50) is disclosed. The tolerance ring (10) comprises a deformable band having a plurality of radially extending projections around its circumference, wherein the projections include a set of axially spaced protuberances (12, 13) separated by a unformed region (11) circumferentially adjacent to an axially elongate protuberance (15), the axial extent of which spans the axial extent of the set of axially spaced protuberances. This arrangement of protuberances facilitates the transfer of retention force to a component that is composed of a plurality of independent parts, e.g. two or more bearings (54, 56) separated by a spacer (58).

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 (15) extending axially from the band (16). The guide surface (15) acts as an enlarged entrance to the band (16) for a shaft (3) to be mounted in the bore (4) by insertion into the tolerance ring. The use of the guide surface (15) 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.

Abstract: A tolerance ring has a band with outwardly extending corrugated protrusions forming waves that engage an outer surface of a shaft. 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 a bore of a housing to assist during assembly.

Abstract: An apparatus includes an inner component, an outer component; and a tolerance ring located between the inner and outer components to provide an interference fit there between. The tolerance ring includes a strip of material having a plurality of radially extending projections. The strip of material is curved into a ring having a gap. The radially extending projections are compressible between the inner and outer components, and the stiffness of the radially extending projections varies around the circumference of the tolerance ring.
