A wear assembly for excavating equipment includes a base fixed to the excavating equipment, a wear member fit over the base, and a lock to releasably hold the wear member to the base. The wear member includes side relief to reduce drag on the system. The wear member and the base each includes a hemispherical front end and a generally trapezoidal rear portion. The base includes a nose and a stop projecting from the nose to cooperate with the lock without an opening being needed to receive the lock into the nose. The lock is an elongate lock positioned generally in an axial direction and which holds the wear member to the base under compressive loads.

La présente invention concerne un assemblage d'usure pour équipement d'excavation qui comprend une base fixée à l'équipement d'excavation, un élément d'usure installé par-dessus la base, et un dispositif de verrouillage pour maintenir l'élément d'usure sur la base de façon libérable. L'élément d'usure comprend un allègement latéral pour réduire la traînée sur le système. L'élément d'usure et la base comprennent chacun une extrémité avant hémisphérique et une partie arrière généralement trapézoïdale. La base comprend un nez et une butée qui fait saillie à partir du nez pour coopérer avec le dispositif de verrouillage sans qu'une ouverture ne soit nécessaire pour recevoir le dispositif de verrouillage dans le nez. Le dispositif de verrouillage est un dispositif de verrouillage oblong positionné généralement dans une direction axiale et qui maintient l'élément d'usure sur la base sous des charges de compression.
