Abstract

A wear member including a body including a leg having an inner face and a first pocket formed in the inner face of the leg. A second pocket may be formed in the inner face of the leg and spaced apart from the first pocket by a passage extending between the first pocket and the second pocket in a direction parallel to a main axis of the body. The second pocket may include a curved abutment surface generally facing away from the first pocket.

Claims

1. A wear member comprising:

a body including a leg having an inner face;

a first pocket formed in the inner face of the leg;

a second pocket formed in said inner face and spaced apart from the first pocket by a passage extending between the first pocket and the second pocket in a direction parallel to a main axis of the body, the second pocket including a curved abutment surface generally facing away from the first pocket.

2. The wear member of claim 1, wherein the first pocket includes laterally opposed feet extending inward from opposing lateral side surfaces, the feet defining longitudinally extending troughs.

3. The wear member of claim 1, wherein the first pocket includes a front surface, opposing lateral side surfaces, a top surface extending between the opposing lateral side surfaces, an open bottom and an open rear.

4. The wear member of claim 3, wherein the open rear of the first pocket is formed in the rear surface of the body.

5. The wear member of claim 4, wherein a recess is formed in the top surface of the first pocket extending longitudinally from the passage to the rear surface.

6. The wear member of claim 5, wherein a depth of the recess is greater adjacent the rear surface than a depth of the recess adjacent the passage.

7. The wear member of claim 1, wherein the second pocket has a width W₃ and the passage has a width W₄, the ratio of the width W₃ of the second pocket to the width W₄ of the passage is greater than 2.0.

8. The wear member of claim 1, wherein the curved abutment surface of the second pocket extends laterally in a direction perpendicular to the main axis of the body.

9. The wear member of claim 1, wherein the curved abutment surface of the second pocket extends laterally outward on both sides of the passage.

10. The wear member of claim 1, wherein the curved abutment surface of the second pocket has a constant radius and extends at least 180°

around a center axis.

11. The wear member of claim 1, wherein the curved abutment surface of the second pocket is concave.

12. A wear member comprising:

a first leg and second leg defining a slot therebetween and converging at a front end, the slot configured to receive a lip of a bucket and the first leg having an inner face defining a first pocket configured to receive a boss therein and a second pocket, the second pocket including a curved abutment surface generally facing the front end and having a width W₃; and

a partition between the first and second pockets, the partition defining a passage between the first pocket and second pocket, the passage having a width W₄, wherein the ratio of the width W₃ of the second pocket to the width W₄ of the passage is greater than 2.0.

13. The wear member of claim 12, wherein the curved abutment surface of the second pocket extends in a direction generally perpendicular to the passage.

14. The wear member of claim 12, wherein the curved abutment surface of the second pocket extends laterally outward on both sides of the passage.

15. The wear member of claim 12, wherein the curved abutment surface of the second pocket has a constant radius and extends 180°

or more around a center.

16. The wear member of claim 12, wherein the curved abutment surface of the second pocket is concave.

17. A wear member comprising:

a front end defining a front edge;

a first leg extending rearward from the front end;

a second leg extending rearward from the front end and spaced from the first leg to define a slot therebetween;

a first pocket formed in an inner face of the first leg;

a second pocket a second pocket formed in said inner face and spaced from the first pocket along a main axis of the first leg, the second pocket including a curved abutment surface generally facing the front end, the curved abutment surface having a generally constant radius and extending greater than 180°

around a center of the circle; and

a partition between the first and second pockets, the partition defining a passage extending between the first pocket and second pocket.

18. The wear member of claim 17, wherein the curved abutment surface of the second pocket is concave.

19. The wear member of claim 17, wherein the curved abutment surface of the second pocket extends laterally outward on both sides of the passage.

20. The wear member of claim 17, wherein a recess is formed in a top surface of the first pocket, the recess extending longitudinally from the passage to a rear surface of the wear member, and wherein a depth of the recess is greater adjacent to the rear surface than a depth of the recess adjacent to the passage.
