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.
Claims20
A method of using a tolerance ring comprising:
- providing a tolerance ring comprising a first axial end and a second axial end, a body having a hollow cylindrical shape, a plurality of protrusions extending radially outward from the body, and a guide having a guide surface contiguous with the body at a minimum guide diameter and extending to a maximum guide diameter coincident with the first axial end of the tolerance ring, wherein a portion of the body is disposed between the guide and the plurality of protrusions;
- inserting the tolerance ring into a bore of a housing;
- and
- inserting a shaft into the body of the tolerance ring so as to create an interference fit between the tolerance ring and the shaft.

A method of using a tolerance ring comprising:
- providing a tolerance ring comprising:
- a body;
- a plurality of protrusions extending radially outward from the body;
- and
- a guide contiguous with, and extending axially from, the body, wherein the guide comprises a guide surface inclined relative to a central axis of the tolerance ring and having a maximum guide diameter coincident with an axial end of the tolerance ring, and wherein the guide extends from an entire circumference of the body;
- inserting the tolerance ring into a bore of a housing;
- inserting a shaft into the body of the tolerance ring, comprising:
- inserting the shaft into the guide of the tolerance ring after inserting the tolerance ring into the bore, wherein a portion of the shaft is disposed within a volume defined by the guide, and wherein the portion of the shaft is entirely spaced apart from the guide;
- and
- continuing insertion of the shaft into the body of the tolerance ring such that the shaft forms an interference fit with the body of the tolerance ring.
