Tolerance ring and shim
First Claim
1. A tolerance ring and shim assembly, said tolerance ring being in the form of a split cylinder defining a longitudinal axis and having a plurality of laterally spaced, axially extending corrugations projecting radially from said cylinder, which is to be sandwiched between an inner cylindrical surface of an outer member and an outer cylindrical surface of an inner member an said shim being in the form of a split cylinder with a smooth surface, comprising:
- annular planished areas located between axial ends of said corrugations and axial ends of said tolerance ring;
at least one shim separate from said tolerance ring and having a diameter sized to cause the shim to engage against at least one of said planished areas, a combined thickness of said shim and planished area being less than a height of said corrugations, but being greater than a height representing a height, below which the corrugations, if crushed to that height, would be beyond their elastic limit.

Abstract
Improvements to tolerance rings are provided permitting them to be utilized in holding cylindrical members within sheet panels and providing positive axial retention of the ring in the sheet panel; permitting them to be used in centered and half-centered mounting arrangements without requiring the formation of shoulders on the engaged members, but rather through the use of an annular split ring shim; and permitting them to be used to restore the effective diameter of worn parts by providing the ring with a bowed shape.

10. A tolerance ring and shim assembly comprising:
-
a tolerance ring being in the form of a split ring cylinder defining a longitudinal axis and having a plurality of laterally spaced, axially extending and uniformly distributed corrugations which project radially from said cylinder and annular planished areas located between axial ends of said cylinder and said corrugations, said cylinder to be sandwiched between an inner cylindrical surface of an outer member and an outer cylindrical surface of an inner member; and a shim being in the form of a separate split smooth surface cylinder and having a diameter sized to cause said shim to engage against a planished area, a combined thickness of said shim and said planished area being less than a height of said corrugations, but being greater than a height at which the corrugations, if crushed to that height, would by beyond their elastic limit.

11. A tolerance ring and shim assembly comprising:
-
a tolerance ring being in the form of a split ring cylinder defining a longitudinal axis and having a plurality of laterally spaced, axially extending corrugations of equal height projecting radially from said cylinder and annular planished areas located between axial ends of said cylinder and said corrugations, one of said planished areas being in an elevated position relative to the other planished area, said tolerance ring to be sandwiched between an outer surface of an inner member and an inner surface of an outer member; and a shim being in the form of a separate split smooth surface cylinder and having a diameter sized to cause said shim to engage against a planished area, a combined thickness of said shim and said planished area being less than a height of said corrugations, but being greater than a height at which the corrugations, if crushed to that height, would be beyond their elastic limit.
