Abstract
A tolerance ring has a hollow band with outwardly extending corrugated protrusions forming waves that engage an inner surface of a bore of a housing. 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 assist the insertion of a shaft into the hollow band during assembly of the ring into the bore of the housing.
Claims9
A method of using a tolerance ring, the method 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 outward from the body away from a central longitudinal axis of the hollow cylindrical shape such that there are no protrusions that extend radially inward from the body, and a tapered guide portion extending axially from at least one segment of an inner circumference of the body having a guide surface coincident and contiguous with the body at a minimum guide diameter and extending to a maximum 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 radially outwardly extending protrusions;
- inserting the tolerance ring axially into a bore of a housing such that the plurality of radially outwardly extending protrusions contact an interior surface of the bore;
- and
- inserting a shaft into the guide portion and through the body of the tolerance ring after inserting the tolerance ring, whereby creating a radial spring force between the shaft and the interior surface of the bore and creating an interference fit between the tolerance ring and the shaft.
