Abstract

A shim for use with a wear member comprises a body that defines a first aperture that includes a closed end and an open end, wherein the first aperture is defined by at least three surfaces including two side surfaces and at least one surface that defines the closed end and that further defines a surface normal that points toward the open end, and a second aperture that includes a closed end and an open end, wherein the second aperture is defined by at least three surfaces including two side surfaces and at least one surface that defines the closed end and that further defines a surface normal that points toward the open end. The surface normal of the first aperture forms an angle with the surface normal of the second aperture that is greater than zero degrees.

Claims

1. A shim for use with a wear member, the shim comprising:

a body that defines;

a first aperture that includes a closed end and an open end, wherein the first aperture is defined by at least three surfaces including two side surfaces and at least one surface that defines the closed end and that further defines a surface normal that points toward the open end; and

a second aperture that includes a closed end and an open end, wherein the second aperture is defined by at least three surfaces including two side surfaces and at least one surface that defines the closed end and that further defines a surface normal that points toward the open end;

wherein the surface normal of the first aperture forms an angle with the surface normal of the second aperture that is greater than zero degrees.

2. The shim of claim 1 wherein the angle is approximately 180 degrees.

3. The shim of claim 1 wherein at least one of the apertures includes three straight surfaces that form angles with each other that are approximately ninety degrees.

4. The shim of claim 3 wherein the side surfaces of the first aperture are coplanar with the side surfaces of the second aperture.

5. The shim of claim 1 wherein the body defines a thickness that is the minimum dimension of the body and at least one aperture ends completely through the thickness.

6. The shim of claim 1 wherein the body includes a spine portion that is disposed between the apertures and wherein the spine defines a sweep axis for the body of the shim.

7. The shim of claim 6 wherein the body defines a third aperture that is similarly configured as the first aperture and a fourth aperture that is similarly configured as the second aperture wherein the first aperture is disposed on the same side of the spine as the third aperture and the second aperture is disposed on the same side of the spine as the fourth aperture.

8. The shim of claim 7 wherein the third and fourth apertures are spaced away from the first and second apertures the same distance along the sweep axis that is straight, forming a rectangular array.

9. The shim of claim 7, wherein the spine changes direction along the sweep axis that also changes direction.

10. The shim of claim 9 wherein the sweep axis comprises a first straight portion and a second straight portion that form an oblique angle with the first straight portion.

11. The shim of claim 9 wherein the oblique angle is approximately 170 degrees.

12. The shim of claim 7 wherein the body further comprises a plurality of projections that extend from the spine, defining the side surfaces of the apertures.

13. The shim of claim 12 wherein the body forms a substantially double H shaped configuration.
