High performance implement wear member

摘要

A wear member for an earth-working implement includes a body having front, rear, top, bottom, inner side and outer side portions. A cutting edge is defined along at least a portion of a bottom interface. The wear member includes a contoured upper front surface, which extends between a top edge along a top interface between the front portion and the top portion, an outer side edge along an outer side interface between the front portion and the outer side portion, a ridge on the front portion, and a spearhead edge along the bottom interface. The wear member includes a contoured lower front surface formed on the front portion of the body adjacent the contoured upper front surface, which is between an inner side edge, which is disposed along an inner side interface between the front portion and the inner side portion, the cutting edge, and the ridge.

1. A wear member for an earth-working implement, the wear member comprising:
a body having front, rear, top, bottom, inner side and outer side portions, wherein a cutting edge is defined along at least a portion of a bottom interface between the front portion and the bottom portion; a contoured upper front surface defined on the front portion, the contoured upper front surface extending between:
a top edge disposed along a top interface between the front portion and the top portion,an outer side edge disposed along an outer side interface between the front portion and the outer side portion,a ridge disposed on the front portion, anda spearhead edge disposed along the bottom interface between the outer side portion and the cutting edge; a contoured lower front surface formed on the front portion of the body adjacent the contoured upper front surface, the contoured lower front surface defined between an inner side edge, which is disposed along an inner side interface between the front portion and the inner side portion, the cutting edge, and the ridge; and a rear surface defined on the rear portion and defining a rear surface plane, the rear surface plane substantially parallel to a normal-lateral plane, wherein a spearhead vertical angle, measured between the normal-lateral plane and the contoured upper front surface adjacent the spearhead edge, is in a range between about 10 degrees and about 25 degrees.
