Abstract

A wear assembly for securing a wear member to excavating equipment that includes a base having a nose and a wear member having a socket. The nose and socket are each provided with one or more complementary stabilizing surfaces in central portions thereof.

Claims (16)

1. A wear assembly for excavating equipment comprising:

a base fixed to the excavating equipment and having a supporting nose and a bearing surface;

a wear member including a front end to contact materials to be excavated by the excavating equipment, a rear end, a socket opening in the rear end for receiving the supporting nose of the base, and an opening, the socket being defined by a top wall, a bottom wall and side walls and including a longitudinal axis, at least one of the top and bottom walls including a pair of centrally located stabilizing surfaces inclined relative to each other in different transverse directions so as to laterally converge toward a central location along the respective top or bottom wall and positioned to bear against complementary surfaces on the nose to resist both vertical and horizontal loads during excavating, each said side wall including a pair of side stabilizing surfaces inclined relative to each other in different transverse directions so as to laterally converge toward a central location along the respective side wall and be positioned to bear against complementary surfaces on the nose to resist both vertical and horizontal loads during excavating, and each said stabilizing surface and each said side stabilizing surface axially extending substantially parallel to the longitudinal axis; and

a lock received into the opening of the wear member and in contact with the bearing surface of the base to hold the wear member to the excavating equipment.

2. A wear assembly in accordance with claim 1 wherein the top and bottom walls of the wear member each includes a pair of said stabilizing surfaces to bear against the complementary surfaces on the base.

3. A wear assembly in accordance with claim 1 wherein each said pair of stabilizing surfaces and said pair of side stabilizing surfaces of the wear member collectively defines a V-shaped formation.

4. A wear assembly in accordance with claim 1 wherein each said pair of stabilizing surfaces and said pair of side stabilizing surfaces of the wear member collectively defines a curved formation.

5. A wear assembly in accordance with claim 1 wherein each said pair of stabilizing surfaces and said pair of side stabilizing surfaces of the wear member defines a projection that fits within a recess defined in the nose.

6. A wear assembly in accordance with claim 1 wherein the stabilizing surfaces and the side stabilizing surfaces of the wear member are located near the rear end of the wear member.

7. A wear member for excavating equipment comprising a front end to contact materials to be excavated by the excavating equipment, a rear end, a socket opening in the rear end for receiving a supporting nose fixed to the excavating equipment, and an opening for receiving a lock to releasably hold the wear member to the nose, the socket being defined by a top wall, a bottom wall and side walls and including a longitudinal axis, at least one of the top and bottom walls including a pair of centrally located stabilizing surfaces inclined relative to each other in different transverse directions so as to laterally converge toward a central location along the respective top or bottom wall and be positioned to bear against complementary surfaces on the nose to resist both vertical and horizontal loads during excavating, each said side wall including a pair of side stabilizing surfaces inclined relative to each other in different transverse directions so as to laterally converge toward a central location along the respective side wall and be positioned to bear against complementary surfaces on the nose to resist both vertical and horizontal loads during excavating, and each said stabilizing surface and said side stabilizing surface axially extending substantially parallel to the longitudinal axis.

8. A wear member in accordance with claim 7 wherein the top and bottom walls each includes a pair of said stabilizing surfaces.

9. A wear member in accordance with claim 7 wherein each said pair of stabilizing surfaces and said pair of side stabilizing surfaces collectively defines a V-shaped formation.

10. A wear member in accordance with claim 7 wherein each said pair of stabilizing surfaces and said pair of side stabilizing surfaces collectively defines a curved formation.

11. A wear member in accordance with claim 7 wherein each said pair of stabilizing surfaces extends from one side wall to the other side wall.

12. A wear member in accordance with claim 7 wherein each said pair of stabilizing surfaces and said pair of side stabilizing surfaces defines a projection that fits within a recess defined in the nose.

13. A wear member in accordance with claim 7 wherein the stabilizing surfaces and the side stabilizing surfaces are located near the rear end.
