Title
(EN) WEAR ASSEMBLY
(FR) ENSEMBLE D'USURE
Abstract
(EN)
A wear assembly for use on various kinds of earth working equipment that includes a base with a supporting portion, a wear member with a cavity into which the supporting portion is received, and a lock to releasably secure the wear member to the base. The supporting portion is formed with top and bottom recesses that receive complementary projections of the wear member. These recesses and projections include aligned holes so as to receive and position the lock centrally within the wear assembly and remote from the wear surface. The hole in the wear member is defined by a wall that includes a retaining structure provided with an upper bearing surface and a lower bearing surface for contacting and retaining the lock against upward and downward movement in the hole.

L'invention concerne un ensemble d'usure s'utilisant sur divers types d'équipements de terrassement, et qui comprend une base comportant une partie de support, un élément d'usure comportant une cavité dans laquelle la partie de support est reçue, et un verrou pour fixer libérable l'élément d'usure à la base. La partie de support est formée de manière à comporter des évidements supérieurs et inférieurs, destinés à recevoir des éléments saillants complémentaires de l'élément d'usure. Ces évidements et parties saillantes comprennent des trous alignés en vue de recevoir et de positionner le verrou d'une manière centrale dans l'ensemble d'usure, et distante par rapport à la surface d'usure. Le trou de l'élément d'usure est défini par une paroi, qui comprend une structure de retenue pourvue d'une surface portante supérieure et d'une surface portante inférieure entrant en contact avec le verrou et qui retiennent celui-ci afin de l'empêcher d'effectuer un mouvement vers le haut et vers le bas dans le trou.
