Abstract
A wear assembly includes an adapter with a nose, a wear member with a socket to receive the nose, and a lock to secure the wear member to the adapter. The nose and socket include complementary rails and grooves that vertically diverge as they extend from the front of the nose. The lock can have a tapered construction.
Claims134
A wear assembly comprising:
- an adapter having a rear mounting end for securing the assembly to a wear surface and a forwardly extending nose;
- a wear member defining a longitudinal axis and including a front working end and a rearwardly opening socket for receiving the nose, the socket being defined by opposed converging surfaces each extending at an inclination to the longitudinal axis and by side surfaces, each side surface including a side bearing surface between the converging surfaces to engage the adapter, wherein each side bearing surface faces toward a different one of the converging surfaces and extends generally in the same inclined direction relative to the longitudinal axis as the converging surface the side bearing surface faces;
- and
- a lock to hold the wear member to the adapter.
A wear assembly comprising:
- an adapter having a rear mounting end for securing the assembly to a wear surface and a forwardly extending nose having a pair of rails;
- a wear member defining a longitudinal axis and including a pair of converging walls extending to a narrowed front working end, a pair of sidewalls, and a rearwardly opening socket defined by the converging walls and the sidewalls, the socket having a groove in each of the sidewalls for receiving the rails on the nose, wherein the grooves diverge from each other and from opposite sides of a plane aligned with the longitudinal axis and extending along the narrowed front working end as they extend rearward, and wherein the grooves are generally aligned with each other along the plane at a front end of the socket;
- and
- a lock for securing the wear member to the adapter.
A wear assembly comprising:
- an adapter having a rear portion adapted to be secured to a wear surface;
- a wear member having a pair of converging walls and a pair of sidewalls;
- wherein one of the adapter and wear member includes a nose, the nose having a pair of converging walls and a pair of sidewalls, and the other of the adapter and wear member includes a socket for receiving the nose;
- wherein one of the nose and socket includes a generally longitudinal rail along each of the sidewalls, and one of the rails is inclined generally in the same direction as each of the converging walls;
- and
- wherein the other of the nose and socket includes a pair of grooves to receive the rails;
- and
- a lock to hold the wear member to the adapter.
A wear assembly comprising:
- an adapter having a rear mounting end adapted to secure the wear assembly to a wear surface, and a forwardly extending nose;
- a wear member including a front working end and a rearwardly opening socket having a longitudinal axis, wherein the socket has over at least a portion of its length a generally Z-shaped cross-sectional configuration when considered generally perpendicular to the longitudinal axis;
- and
- a lock for securing the wear member to the adapter.
A wear assembly comprising:
- an adapter including a rear mounting end for securing the wear assembly to a wear surface and a forwardly extending nose;
- a wear member defining a longitudinal axis and including a front working end and a rearwardly opening socket for receiving the nose;
- the nose and socket including plurality of cooperating linear rails and grooves that require the wear member to rotate generally about the longitudinal axis when installed and removed from the nose;
- and
- a lock to hold the wear member to the adapter.
A wear assembly comprising:
- an adapter including a rear mounting end for securing the wear assembly to a wear surface and a forwardly extending nose having longitudinal rails, with only one rail on each side;
- a wear member including a front working end and a rearwardly opening socket defined by side surfaces and converging surfaces, the socket having a groove on each of the side surfaces for receiving the rails, the grooves each being defined by one of the converging surfaces on one side of the groove and a side bearing surface on the other side of the groove, wherein the side bearing surfaces face in opposite directions and are spaced from each of the converging surfaces;
- and
- a lock for holding the wear member to the adapter.
A wear assembly comprising:
- an adapter including a rear mounting end for securing the wear assembly to a wear surface and a forwardly extending nose;
- a wear member including a front working end and a rearwardly opening socket defined by side surfaces and converging surfaces, wherein the side surfaces diverge as they extend toward the front working end;
- and
- a lock for holding the wear member to the adapter.
A wear member defining a longitudinal axis and including a front working end and a rearwardly opening socket for receiving the nose, the socket being defined by opposed converging surfaces each extending at an inclination to the longitudinal axis and by side surfaces, each side surface including a side bearing surface between the converging surfaces to engage the adapter, wherein each side bearing surface faces toward a different one of the converging surfaces and extends generally in the same inclined direction relative to the longitudinal axis as the converging face the side bearing surface surfaces.
A wear member defining a longitudinal axis and including a pair of converging walls extending to a narrowed front working end, a pair of sidewalls, and a rearwardly opening socket for receiving a nose of an adapter, the socket being defined by the converging walls and the sidewalls, the socket having a groove in each of the sidewalls for receiving rails on the adapter nose, wherein the grooves diverge from each other and from opposite sides of a plane aligned with the longitudinal axis and extending along the narrowed front working end as they extend rearward, and wherein the grooves are generally aligned with each other along the plane at a front end of the socket.
A wear member including a front working end and a socket opening in a rear end of the wear member and having a longitudinal axis, wherein the socket has over at least a portion of its length a generally Z-shaped cross-sectional configuration when considered generally perpendicular to the longitudinal axis.
A wear member including a front working end and a rearwardly opening socket defined by side surfaces and converging surfaces, the socket having only one groove on each of the side surfaces for receiving the rails, the grooves each being defined by one of the converging surfaces on one side of the groove and a side bearing surface on the other side of the groove, wherein the side bearing surfaces face in opposite directions and are spaced from each of the converging surfaces.
A wear member in accordance with claim 1100 wherein the side bearing surfaces extend generally at the same inclination as the converging surface which it faces.
A wear member comprising a front working end and a rearwardly opening socket defined by side surfaces and converging surfaces, wherein the side surfaces diverge as they extend toward the front working end.
A lock for a wear assembly for an excavator having an adapter and a wear member, the lock comprising:
- an elongate body that tapers toward one end along at least a substantial length of the body;
- and
- a movable lock member that extends laterally from the body to secure the lock in the wear assembly.
A wear assembly for an excavator having a digging edge comprising:
- a nose fixed to the excavator and projecting forward from the digging edge to a front end, the nose having first and second walls converging toward the front end, and a pair of opposite sides interconnecting the first and second walls, each said side including a rail, a first one of the rails being oriented in the same general inclination as the first wall, and a second one of the rails being oriented in the same general inclination as the second wall;
