Lock for a wear assembly
Wear members for wear assemblies include a lock configured to secure the wear member to a base, where the lock has two engagement positions, namely: (a) a first position that secures the lock to the wear member, and (b) a second position that secures the wear member to the base. The locks are further configured to be unlatched and removed from the wear member in two phases, a first retraction of the latching mechanism, followed by a rotation of the lock itself with removal from the wear member.
1. A lock for securing a wear member to ground-engaging equipment comprising:
a lock body including a front bearing surface for contacting a base on the ground-engaging equipment and a rearwardly-opening recess for receiving a complementary support in a hole in the wear member;
an actuator member movably coupled to the lock body; and
a latch member movably coupled to the actuator member and the lock body such that movement of the actuator member relative to the lock body moves the latch member between a latched position in which a portion of the latch member extends outward in a direction to engage a wear member and an unlatched position in which the latch member is retracted relative to the latched position.
2. A lock according to claim 1 including a resilient member for biasing the latch member toward the latched position.
3. A lock according to claim 1 wherein the actuator member rotates in the lock body on a first axis, and the latch member is pivotable about a second axis between the latched and unlatched positions.
4. A lock according to claim 3 wherein the first axis and the second axis are parallel and non-aligned.
5. A lock according to claim 3 wherein the first axis and the second axis are non-parallel.
6. A lock according to claim 3 wherein the first axis diverges from the second axis at an angle from 0° to 45° as measured in a plane to which both axes are projected.
7. A lock according to claim 1 wherein the actuator member includes a first end having a tool interface and a second end opposite the first end, wherein the second end includes a cam for engaging the latch member and translating motion of the actuator member to the latch member for moving the latch member between the latched and unlatched positions.
