Abstract
A retaining assembly includes a fastener and a first retaining member carried by the fastener. The first retaining member may have a generally planar surface and a curved abutment surface extending from the generally planar surface to form a generally semi-circular end profile of the first retaining member. The first retaining member may be configured to be received in a pocket of a wear member. A second retaining member may be carried by the fastener, the second retaining member spaced from the first retaining member along a main axis of the fastener.
Claims20
A retaining assembly comprising:
- a fastener;
- a first retaining member carried by the fastener and having a generally planar surface and a curved abutment surface extending from the generally planar surface to form a generally semi-circular end profile of the first retaining member, the first retaining member configured to be received in a pocket of a wear member;
- and
- a second retaining member carried by the fastener, wherein the second retaining member is spaced from the first retaining member along a main axis of the fastener, the second retaining member configured to engage a boss.
A retaining assembly comprising:
- a fastener having a first end and a second end, the fastener including a shank extending longitudinally between the first and second ends and a threaded portion adjacent the first end of the shank;
- a first retaining member carried by the fastener adjacent said first end, the first retaining member including a generally planar surface, a curved abutment surface extending from the generally planar surface to form a generally semi-circular end profile and a threaded bore, the first retaining member configured to be received in a pocket of a wear member, the threaded bore in the first retaining member engaging the threaded portion of the shank to secure the first retaining member to the fastener;
- and
- a second retaining member carried by the fastener adjacent the second end, the second retaining member having a curved abutment surface.
A wear assembly comprising:
- a boss secured to a bucket lip;
- a wear member including a body with a leg having an inner face;
- a first pocket formed in the inner face of the leg;
- and a second pocket formed in said inner face and spaced apart from the first pocket by a passage extending between the first pocket and the second pocket along a main axis of the leg, the second pocket including a curved abutment surface generally facing away from the first pocket;
- and
- a retaining assembly including a fastener;
- a first retaining member carried by the fastener and having a generally planar surface and a curved abutment surface extending from the generally planar surface to form a generally semi-circular end profile of the first retaining member, and a second retaining member carried by the fastener, wherein the second retaining member is spaced from the first retaining member along a main axis of the fastener, the second retaining member configured to engage the boss, wherein the curved abutment surface of the first retaining member is configured to contact the curved abutment surface of the second pocket, the retaining assembly acting to retain the wear member on the bucket lip.
