Wear assembly

摘要

A wear assembly with strain relief protects exposed surfaces of excavating equipment such as a bucket lip. Wear components may include a seat where loads are applied, welding flanges flanking the seat on opposite ends of the component welded to the equipment, and strain relief areas between each welding flange and the seat. The strain relief balances stresses from loading in the wear assembly across the weld flange to limit cracking from stress concentrations. Strain relief may include modification of material properties or modification of component configuration to reduce stiffness of the component between the weld flanges and the seat.

主权项

1. A base for mounting a wear member to a digging edge of an excavating bucket including:
a seat to receive the wear member; inner and outer weld flanges rearward of the seat, each weld flange welded to one of an inner and an outer surface of the digging edge of the excavating bucket; an inner strain relief separating the seat and the inner weld flange; and an outer strain relief separating the seat and the outer weld flange;where the seat spaces and separates the inner and outer strain reliefs.
