Abstract
A method of using a tolerance ring in conjunction with a relatively soft material while preventing deformation of the soft material is provided through the use of a split cylinder shim between the tolerance ring and the soft material. This arrangement can be used whether the soft material is surrounded by the tolerance ring, surrounds the tolerance ring or both.
Claims7
A tolerance ring and shim assembly for use in conjunction with a cylindrical surface of a relatively soft material, 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, one of said members being formed of a relatively soft material compared to said tolerance ring and said shim being in the form of a split cylinder with a smooth surface, comprising:
- said shim having a diameter sized to engage against said soft material cylindrical surface, and
- said tolerance ring having a diameter sized to engage against said shim on an opposite side of said shim from said soft material cylindrical surface,
- whereby, said shim will prevent said corrugations from deforming said soft material cylindrical surface.
A method of preventing deformation of a cylindrical surface in a relatively soft material by a tolerance ring 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, said tolerance ring being sandwiched between an inner cylindrical surface of an outer member and an outer cylindrical surface of an inner member at least one of said members being formed of a relatively soft material in comparison to said tolerance ring, comprising the step of inserting a shim in the form of a split cylinder having smooth cylindrical inner and outer surfaces between said tolerance ring and said relatively soft material.
