摘要： A method of installing a wear member on a lip of an excavator wherein the lip has a through-hole and a boss on each side of the lip includes the steps of placing a wear member including a pair of rearwardly extending legs, each of the legs having a longitudinal slot and a transverse opening, on a lip such that the legs straddle the lip; moving the wear member rearward relative to the lip such that each boss moves axially into one of the slots until reaching a mounting position where the opening in the wear member is generally aligned with the through-hole in the lip; and placing a lock into the opening and the through-hole. Also disclosed is a boss to be fixed to a lip of an excavating bucket for supporting a wear member attached to the lip. The boss comprises a main body to be received in a slot of the wear member, the main body having an inner surface to set against a face of the lip and a pair of opposite sidewalls; and a stem extending generally outward from the inner surface to fit within a hole in the lip.

摘要： Coupling assemblies for releasably holding separable parts together, and in particular for releasably securing a wear member to a support structure in excavating equipment are formed so as to provide increased take up to ensure a tight fit of the wear member on the support structure even if considerable deviation between the parts exists due to wearing, manufacturing variations or the like. The coupling assemblies are suitable for securing points, adapters, shrouds, or other replaceable component to various excavating equipment. The components of the coupling assembly include a wedge and a spool that pivots about a fulcrum when the wedge is driven into assembly for increased take up capabilities. The spool is rotatably engaged around a fulcrum of the support structure and has a bearing portion that bears against and moves the wear member to be secured to thereby take up any gaps between the engaging surfaces of these members. A movable insert may be provided to improve the cooperation between the wedge and the spool to further increase the available take up.

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： In a wear assembly for securing wear members to excavating equipment, a spool iis used with a wedge to hold the wear member in place. The spool is formed with at. least one laterally extending arm at its upper end in lieu of an axial arm such as useid in a conventional C-shaped spool. In this way, the spool can be easily supported in the assembly as the wedge is installed. The spool does not fall through the opening and no special care is needed to prevent it from falling. The spool also holds itself in place when the wedge is driven into the passage. As a result, installation of the wear assembly is easier and less hazardous. In addition, the lateral support reduces the risk that the spool will suffer spreading.
摘要翻译： 在用于将磨损构件固定到挖掘设备上的磨损组件中，卷轴i与楔形件一起使用以将磨损构件保持就位。 阀芯由at形成。 至少一个横向延伸臂在其上端代替轴向臂，例如在传统的C形卷轴中使用。 通过这种方式，可以在安装楔子时轻松地将阀芯支撑在组件中。 阀芯不会从开口落下，也不需要特别注意防止其掉落。 当楔子被推入通道时，阀芯也保持在原位。 因此，磨损组件的安装更容易且危害更小。 另外，侧向支撑减少了线轴将会传播的风险。

摘要： A wear member that includes a pair of legs defining a slot straddles the digging edge of a piece of excavating equipment. In one construction, the slot is formed at its front end with a pair of inclined surfaces and a laterally extending ridge that is fit within a complementary channel on the digging edge. A lock is received within an opening in the wear member to releasably secure the wear member to the digging edge.

摘要： A dredge cutterhead has a plurality of helical arms (32) interconnecting a hub (28) and a ring (30). Each of the arms (32) has a front leading edge (40) for attachment of cutting teeth (34). In one aspect, each of the arms (32) has a trough (44) portion, and the arm (32) is shaped such that dredged material is directed toward the ring (30) along the center of the trough portion (44). In another aspect, the ring (30) of the cutterhead defines an annular channel (66) for receiving loosened material.

摘要： A wear assembly for attaching to a digging edge of an excavator includes a boss, a wear member and a lock. The boss (24) is fixed to the excavator and defines a T-shaped coupling structure. The adapter (10) includes a rearwardly extending mounting leg (54) and a forwardly extending working end (56). The leg includes a T-shaped slot adapted to be received over the T-shaped structure of the boss. The adapter leg further includes an opening for receiving a lock (26). The lock (26) includes an adjustment assembly (92) for eliminating any looseness which may exist between the adapter (10) and the boss (24).

摘要： A wear assembly that includes a wear member and a boss (20) to define an opening for receiving a lock (56) forward of the front edge face of the lip (12) which can mount the wear member in a stable and balanced manner without a through-hole in the lip (12). The wear member includes an aperture and a rib to define bearing faces on opposite sides of a central plane of the lip (12). The boss (20) includes rails to hold the wear member in place, and a brace at the rear end, which supports the rails on the boss (20), abuts the rear of the wear member to reduce the loading on the lip (12), and deflects earthen material away from the wear member under reverse loading.
