Tolerance rings
First Claim
1. A tolerance ring for positioning between two radially spaced annular surfaces comprisinga metallic strip of resilient sheet metal of split ring shape having cylindrical side rims and a plurality of individual resilient corrugations extending from said strip and uniformly spaced around the periphery of the strip,said corrugations being positioned intermediate said rims and spaced from each other,the corrugations being of a plurality of heights of different dimensions whereby successively different radial spring actions are exerted upon force application on the corrugations in any individual direction, the corrugations of any specific height providing identical multiple spring actions when positioned between said radially spaced annular surfaces.

Abstract
A tolerance ring is provided having a plurality of corrugations of different heights to provide different available spring rates even if one or more of the corrugations of one height is crushed. The corrugations of different heights can be in a single row or in a plurality of rows.

6. A tolerance ring for positioning between two radially spaced annular surfaces comprising
a metallic strip of resilient sheet metal of ring shape having a pair of cylindrical side rims and a central cylindrical portion, a first row of individual resilient corrugations of a predetermined height uniformly spaced around said strip and disposed between one of said side rims and said central portion, a second row of individual resilient corrugations uniformly spaced around said strip of a different predetermined height and disposed between the other of said rims and said central portion, said rows of corrugations providing a plurality of spring actions in any individual radial direction and, dependent on the predetermined height, identical multiple spring actions in all directions when positioned between said radially disposed surfaces.
