A fastener () in the form of a strip () of material in the form of a ring which in plan view is profiled to conform to an annular gap (H) between a first component (A) bounded by the fastener () and a second component (B) bounding the fastener (); the ring member having ends providing a gap (G) in plan view; the strip of material having a first side () and a second side (); and having a series of integral fingers (-) spaced along the length of the ring and projecting, in plan view, outwardly from the ring whether from the first side (), the second side (), or both sides thereof. In a further version the ring includes a further series of discrete projections formed integrally from the strip and lying around the ring member in between members of the series of fingers.

Fastener

A combination mounting ring of resilient material, for connecting a shaft within a bore of a housing, has a hollow cylindrical part having radially extending projections. This part is for locating between the outer surface of the shaft and the inner surface of the bore, the radially extending projections being under compression and thus securing the shaft within the bore. The combination mounting ring further has an axial spring element extending radially inward from the cylindrical part and having two portions at different axial positions. The axial spring element is for locating between the shaft and a body axially displaced from the shaft, and serves to minimize axial movement of the shaft within the bore of the housing. The axial spring element may either be an annular part or a tab extending from an axial edge of the cylindrical part.

Combination mounting ring

A mounting assembly comprising mating inner and outer components () mounted together using a tolerance () is disclosed. The tolerance ring () has radially extending projections () that are configured to cause the tolerance ring () to operate into the plastic phase of its compression force/retention force characteristic. This can be achieved by using softer projections than those found in conventional tolerance rings. The force required to mount the tolerance ring and a range of retention forces exhibited by it for a given variance in sizes of mating components is thereby stabilized.
