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 tolerance ring having a first axial end and a second axial end, comprising:
- a body having an axis, a hollow cylindrical shape, a body diameter, and an interior of the body defines a body load bearing area;
- a plurality of protrusions, all of which extend radially outward from the body relative to the axis, having a maximum protrusion diameter that exceeds the body diameter, and the protrusions define a protrusions load bearing area;
- and
- a guide surface having a tapered shape extending from a maximum guide diameter that does not exceed the maximum protrusion diameter toward a minimum guide diameter coincident with the body, wherein the guide surface is contiguous with the body load bearing area, the maximum guide diameter is coincident with the first axial end, and the first axial end is closer to the maximum guide diameter as compared to the minimum guide diameter,
- wherein:
- the body is spaced apart from the first axial end of the tolerance ring;
- the guide surface is disposed between the body and the first axial end;
- a portion of the body is disposed between the guide surface and the plurality of protrusions;
- and
- at least two protrusions of the plurality of protrusions lie along a same circumferential row.
