摘要： A wear assembly for excavating equipment which includes a wear member and a base each with upper and lower stabilizing surfaces that are offset and at overlapping depths to reduce the overall depth of the assembly while maintaining high strength and a stable coupling. The nose and socket each includes a generally triangular-shaped front stabilizing end to provide a highly stable front connection between the nose and wear member for both vertical and side loading. The lock is movable between hold and release positions to accommodate replacing of the wear member when needed, and secured to the wear member for shipping and storage purposes.

摘要： Disclosed are various exemplary embodiments of a lock for a ground engaging tool. In one exemplary embodiment, the lock may include an upper portion having a tool interface configured to receive a tool for applying torque about a lock rotation axis, a lower portion including a base located opposite the tool interface along the lock rotation axis, and an insert layer positioned between the upper portion and lower portion. The insert layer may be configured to allow the upper portion to move relative to the lower portion without shearing when torque is applied to the tool interface of the upper portion.

摘要： Disclosed are various exemplary embodiments of a retainer bushing for use with a lock in a ground engaging tool. The retainer bushing may include a skirt extending around a retainer axis, where the skirt may include an outer surface configured to mate with a lock cavity of the ground engaging tool and an inner surface configured to rotatably receive an outer surface of the lock. The retainer bushing may also include a detent projection extending radially inward from the inner surface with respect to the retainer axis and configured to engage a detent recess of the lock to releasably hold the lock. The detent projection may include a convex surface with a substantially constant radius, and a center of the radius of the convex surface may be positioned at a first distance from the retainer axis that is greater than a second distance between the retainer axis and the outer surface of the skirt.

摘要： A method and apparatus for installing and removing shrouds from the lips of an earth moving bucket. The lips have forwardly converging upper and lower surfaces which are engaged by correspondingly rearwardly diverging legs of the shrouds that overly and are in contact with the lip surfaces. A hole is provided in the lip and an oblong hole in one of the legs that is aligned with the hole and has axially extending, spaced-apart flat walls which define engagement ledges that face and overlap the bore. A connector for securing the shroud to the lip is placed in the bore and the hole and has shaped exterior surfaces for positioning between the walls so that the connector is axially movable along the walls and past the engagement ledges while relative rotations between the connector and the hole in the leg are prevented.

摘要： A tool for removing a chisel, in particular from a chisel holder, having a base element which receives an actuating member, wherein the actuating member has an expeller mandrel. The actuating member is adjustable along a displacement direction. In order to be able to perform the removal simply and rapidly, the actuating member of this invention is indirectly or directly coupled to a piston of a fluid-charged cylinder, or to an electric motor unit.

摘要： A replaceable wear point of excavating equipment, such as a tooth of an excavator bucket, is mounted on the bucket's nose piece using a conventional fastener arrangement plus an adhesive, preferably epoxy, injected into the tooth pocket to fill a gap between the nose piece and the tooth pocket. For injecting the epoxy, a hole is preferably formed through the tooth to communicate into the bottom of the tooth pocket. The injected epoxy preferably squeezes out of the tooth pocket opening and is smoothed to form an epoxy fillet along the junction of the tooth and the nose piece. The epoxy fills gaps, holds the tooth tight against wiggling on the nose piece, and seals out grit and water, to prevent or reduce interior wear of the tooth pocket and the nose piece, and to prevent or delay the tooth from falling off the nose piece.
