Abstract

A corner segment, configured to be mounted to a work implement, may include a body having a plurality of surfaces including a rear surface, an upper surface, a front surface, a bottom surface, an outer side surface, an inner side surface, and a corner surface that is adjacent to each of the front surface, the outer side surface, the upper surface, and the bottom surface. A portion of the bottom surface forms a bottom surface wear zone, and a portion of the front surface forms a front surface wear zone, The corner segment may also include a plurality of protrusions provided on wear zones, the wear zones including the bottom surface wear zone and the front surface wear zone.

First claim

We claim:

1. A corner segment configured to be mounted to a work implement, the corner segment comprising:
a body having a plurality of surfaces including:
a rear surface;
an upper surface;
a front surface;
a bottom surface;
an outer side surface;
an inner side surface; and
a corner surface that is adjacent to each of the front surface, the outer side surface, the upper surface, and the bottom surface,
wherein a portion of the bottom surface forms a bottom surface wear zone, and a portion of the front surface forms a front surface wear zone; and

a plurality of protrusions provided on each of the bottom surface wear zone and the front surface wear zone, wherein the bottom surface includes a planar portion, a ridged portion adjacent to the planar portion, and an inclined portion that is adjacent to the ridged portion and to the front surface, and that is angled relative to the planar portion, the ridged portion and the inclined portion having the bottom surface wear zone with protrusions.

2. The corner segment of claim 1 , wherein the bottom surface wear zone is formed only on an outer half of the bottom surface that is adjacent to the corner surface.

3. The corner segment of claim 1 , wherein the front surface wear zone is formed only on an outer half of the front surface that is adjacent to the corner surface.

4. The corner segment of claim 1 , wherein the corner surface forms a corner surface wear zone and a portion of the outer side surface forms a side surface wear zone.

5. The corner segment of claim 4 , wherein the side surface wear zone is formed only on an edge of the side surface that is adjacent to the corner surface.

6. The corner segment of claim 4 , wherein front surface protrusions, of the plurality of protrusions, are provided on the front surface wear zone, and are aligned along a width of the front surface,
wherein bottom surface protrusions, of the plurality of protrusions, are provided on the bottom surface wear zone, and are positioned along at least one arc that extends across the bottom surface,
wherein side surface protrusions, of the plurality of protrusions, are provided on the side surface wear zone, and are positioned along at least one arc that extends across the side surface, and
wherein corner surface protrusions, of the plurality of protrusions, are provided on the corner surface wear zone, and are positioned along at least one arc that extends across the corner surface.

7. The corner segment of claim 1 , wherein the plurality of protrusions are evenly spaced from each other.

8. The corner segment of claim 1 , wherein the plurality of protrusions are formed of a material having a greater hardness than a material that forms the body of the corner segment.

9. A corner segment configured to be mounted to a work implement, the corner segment comprising:
a body including:
a mounting portion having a mounting portion outer side surface; and
a lip portion, integrally formed with the mounting portion, the lip portion having:
a lip portion front surface;
a lip portion upper surface;
a lip portion bottom surface; and
a lip portion outer corner surface that is adjacent to each of the lip portion front surface, the lip portion upper surface, the lip portion bottom surface, and the mounting portion outer side surface,

wherein a portion of the lip portion bottom surface forms a bottom surface wear zone, and a portion of the lip portion front surface forms a front surface wear zone; and
a plurality of protrusions provided on each of the bottom surface wear zone and the front surface wear zone, wherein the bottom surface of the lip portion includes an angled lip portion that extends at an angle relative to the bottom surface of the mounting portion, and a ridged portion.

10. The corner segment of claim 9 , wherein the bottom surface wear zone is formed only on an outer half of the lip portion bottom surface that is adjacent to the lip portion corner surface.

11. The corner segment of claim 9 , wherein the front surface wear zone is formed only on an outer half of the lip portion front surface that is adjacent to the lip portion corner surface.

12. The corner segment of claim 9 , wherein the corner surface forms a corner surface wear zone and a portion of the outer side surface forms a side surface wear zone.

13. The corner segment of claim 12 , wherein the side surface wear zone is formed only on an edge of the mounting portion outer side surface that is adjacent to the lip portion corner surface.

14. The corner segment of claim 13 , wherein front surface protrusions, of the plurality of protrusions, are provided on the front surface wear zone, and are aligned along a width of the lip portion front surface,
wherein bottom surface protrusions, of the plurality of protrusions, are provided on the bottom surface wear zone, and are positioned along at least one arc that extends across the lip portion bottom surface,
wherein side surface protrusions, of the plurality of protrusions, are provided on the side surface wear zone, and are positioned along at least one arc that extends across the mounting portion outer side surface, and
wherein corner surface protrusions, of the plurality of protrusions that are provided on the corner surface wear zone, are arranged in a staggered pattern on the lip portion corner surface.

15. The corner segment of claim 9 , wherein the plurality of protrusions are evenly spaced from each other.

16. The corner segment of claim 9 , wherein the plurality of protrusions are formed of a material having a greater hardness than a material that forms the body of the corner segment.
