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.
1. A wear member for excavating equipment comprising a front end and a rear end, the front end to contact materials to be excavated during digging by the excavating equipment, the rear end defining a rearwardly-opening socket to receive a supporting nose on the excavating equipment and being free of rearward projections to be received into the nose, the socket being defined by a top wall, a bottom wall and side walls and having a longitudinal axis, at least one of the top and bottom walls including a stabilizing projection extending into the socket along at least a central portion thereof, each said stabilizing projection having bearing surfaces facing generally away from each other to bear against opposite sides of a recess in the nose, each said bearing surface having a transverse inclination so as to resist loads applied in a vertical direction, and each said bearing surface axially extending substantially parallel to the longitudinal axis, each of the side walls including a side stabilizing projection for receipt within a recess in the nose, each said side stabilizing projection having side bearing surfaces facing generally away from each other to bear against opposite sides of a recess in the nose, each said side bearing surface having a transverse inclination to resist loads applied in a vertical direction, and each said side bearing surface axially extending substantially parallel to the longitudinal axis.
2. A wear member in accordance with claim 1 wherein each said stabilizing projection is spaced from the side walls and located near the rear end.
3. A wear member in accordance with claim 1 wherein each of the top and bottom walls includes one of the stabilizing projections.
4. A wear member in accordance with claim 1 wherein each said stabilizing projection has a generally V-shaped transverse configuration.
5. A wear member in accordance with claim 1 wherein each said stabilizing projection has a generally curved transverse configuration.
6. A wear member in accordance with claim 1 wherein each said side stabilizing projection spaced from the top and bottom walls.
7. A wear member in accordance with claim 1 wherein each said side stabilizing projection has a generally V-shaped transverse configuration.
8. A wear member in accordance with claim 1 further including at least one hole for receiving a lock to secure the wear member to the excavating equipment.
9. A wear member in accordance with claim 1 wherein at least one of the top and bottom walls includes a plurality of the stabilizing projections.
10. A wear member in accordance with claim 1 wherein each of the bearing surfaces of each said stabilizing projection and each said side stabilizing projection diverge rearwardly from the longitudinal axis by no more than about five degrees.
11. A wear member in accordance with claim 1 wherein each said stabilizing projection and each said side stabilizing projection has a generally curved transverse configuration.
12. A wear member in accordance with claim 1 wherein each of the bearing surfaces of each said stabilizing projection diverges rearwardly from the longitudinal axis by no more than about five degrees.
