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.
Claims8
A method of using a tolerance ring comprising:
- providing a tolerance ring of a resilient material comprising a first axial end and a second axial end, a body having a hollow cylindrical shape, a plurality of corrugated protrusions extending radially inward from the body towards a central longitudinal axis of the hollow cylindrical shape such that there are no protrusions that extend radially outward from the body, and a tapered guide portion extending axially from at least one segment of an outer circumference of the body having a guide surface coincident and contiguous with the body at a maximum guide diameter and extending to a minimum guide diameter at a free end of the guide portion forming the first axial end of the tolerance ring, wherein at least a portion of the body having no radial protrusions is disposed axially between the guide portion and the plurality of protrusions;
- inserting a shaft into the body of the tolerance ring so as to create an interference fit between the tolerance ring and the shaft by compressing the radially extended protrusions, and
- inserting the tolerance ring and the shaft axially into a bore of a housing, wherein the first axial end is inserted first into the bore of the housing such that the outer circumference surface of the body engages an interior surface of the bore, whereby creating a radial spring force between the shaft and the interior surface of the bore.
