Abstract
A wear member includes a first leg, a second leg, and a throat portion connecting the first leg to the second leg. The first leg defines a first leg thickness, and the throat portion defines a throat portion thickness disposed adjacent to the first leg thickness. A ratio of the throat portion thickness to the first leg thickness ranges from 1.1 to 1.2.
Claims20
A wear member configured to be attached to a work implement, the wear member comprising:
- a first leg;
- a second leg;
- and
- a throat portion connecting the first leg to the second leg;
- wherein a first portion of the first leg extends from a rear surface defined by the first leg,
- wherein a second portion of the first leg extends from an end of the second leg and to the first portion of the first leg,
- wherein the second leg extends from the end of the second leg and to the throat portion,
- wherein a third portion of the first leg extends from the second portion of the first leg and to the throat portion,
- wherein a combined length of the first portion of the first leg and the second portion of the first leg is longer than a length of the third portion of the first leg,
- wherein the first portion of the first leg includes a projection that extends to the rear surface, that projects above a topmost surface of the second portion of the first leg, and that extends laterally across a midplane of the wear member,
- wherein the first leg defines a first leg thickness,
- wherein the throat portion defines a throat portion thickness disposed adjacent to the first leg thickness, and
- wherein a ratio of the throat portion thickness to the first leg thickness ranges from 1.1 to 1.2;
- and
- a lifting eye extending from the throat portion to the first portion of the first leg.

A shroud configured to be attached to an edge of a work implement, the shroud comprising:
- a top leg with a rear surface having a rear gate blemish;
- a bottom leg with a bottom surface having a bottom gate blemish;
- and
- a throat portion including:
- a first beveled portion extending from the top leg,
- a second beveled portion extending from the first beveled portion to the bottom leg, and
- a rib that is spaced away from a first lateral side of the throat portion and a second lateral side of the throat portion,
- wherein a first portion of the top leg extends from the rear surface,
- wherein a second portion of the top leg extends from beyond an end of the bottom leg and to the first portion of the top leg,
- wherein the bottom leg extends from the end of the bottom leg and to the second beveled portion,
- wherein a third portion of the top leg extends from the second portion of the top leg and to the first beveled portion,
- wherein a combined length of the first portion of the top leg and the second portion of the top leg is longer than a length of the third portion of the top leg,
- wherein the second portion of the top leg defines a top leg thickness,
- wherein the first beveled portion defines a first beveled portion thickness that is greater than the top leg thickness, and
- wherein the first portion of the top leg includes a projection that projects above a topmost surface of the second portion of the top leg, that extends to the rear surface, and that extends laterally across a midplane of the shroud.
