摘要:
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 having a pair of grooves each on opposite sides of the socket for receiving the rails, wherein each groove diverges from a plane aligned with the longitudinal axis and extending along the narrowed front working end; and a lock for securing the wear member to the adapter.

An assembly for mounting an excavating tooth (30) particularly suited for a dredge cutterhead includes a base (52), an adapter (34), and a lock (36). The base (32) includes a convex, curved bearing surface that abuts a concave, curved bearing surface on the adapter. The curved bearing surfaces are able to maintain substantially full contact with each other under transverse loading.

A wear assembly includes an adapter (14) with a nose (18), a wear member (12) with a socket (53) to receive the nose (18), and a lock (16) to secure the wear member (12) to the adapter (14). The nose (18) and socket (53) include complementary rails (35) and grooves (65) that vertically diverge as they extend from the front of the nose (18). The lock (16) can have a tapered construction.

A mounting bracket (90) for mounting a working device (12) to a boom (40) of a carrier includes a base (92), flanges (94) for attaching the bracket (90) to the boom (40), and ears (98) for attaching the working device (12) to the bracket (90). The ears (98) each define a hole (111) for pivotally coupling the working device (12) thereto for free pivotal movement about a single axis to alleviate the generation of excessive side forces. The bracket (90) further includes stops (117) to limit the free angular movement so that the working device (12) can be oriented at an inclination and so that it may be used to pry pieces of the worked material.

L'invention se rapporte à une tête (27) de dent excavatrice, qui comporte une ouverture (37) destinée à recevoir une broche, une cavité (40) contenue dans la tête et communiquant avec l'ouverture ainsi qu'un organe de verrouillage résilient (32) servant à bloquer en position la broche (31) dans la cavité.
摘要:
An assembly of wear element (11) for installation on the wearable part of a structure engageable with abrasive material including a relatively elongated base element adapted to be secured to the wearable part and a relatively elongated wear element releasably, reversibly mounted on the base element, each of the elements having longitudinally spaced apart dovetail surfaces (30) in one outstanding wall portion and at least one surface in a second opposed outstanding wall portion positioned between the spaced art dovetail surfaces. A method of designing the dovetail connection through a repeating pattern is also disclosed.
