Abstract
A bucket lip includes an elongate one-piece casting and each of a first lip wing projecting upward at a location adjacent to a first lateral edge and a second lip wing projecting upward at a location adjacent to a second lateral edge of the casting. The first lip wing and the second lip wing each include a base section that is laterally asymmetric, and a bucket wing attachment section. Embodied in a bucket lip assembly, wing shroud bosses may be attached to outboard sides of the first lip wing and the second lip wing.
Claims20
A bucket lip comprising:
- an elongate one-piece casting including an upper lip side having an upper lip surface extending in a lateral direction between a first lateral edge and a second lateral edge, and in a fore-aft direction between a forward lip edge and a back lip edge, and a lower lip side;
- a first lip wing projecting upward at a location adjacent to the first lateral edge;
- a second lip wing projecting upward at a location adjacent to the second lateral edge;
- and
- the first lip wing and the second lip wing each having an outboard transition surface defining a smaller radius of curvature, and an inboard transition surface defining a larger radius of curvature and transitioning to the upper lip surface.
A bucket lip comprising:
- an elongate one-piece casting including an upper lip surface, a first lateral edge, a second lateral edge, a forward lip edge, and a back lip edge;
- a first lip wing projecting upward at a location adjacent to the first lateral edge;
- a second lip wing projecting upward at a location adjacent to the second lateral edge;
- and
- the first lip wing and the second lip wing each having a base section attached to the upper lip surface, and a bucket wing attachment section extending upwardly from the respective base section;
- and
- the base section in each of the first lip wing and the second lip wing is laterally asymmetric about a midplane defined by the respective bucket attachment section.
A bucket lip assembly comprising:
- a bucket lip including an upper surface, a lower surface, a first lateral edge, a second lateral edge, a forward lip edge, and a back lip edge;
- the bucket lip further including a first lip wing projecting upward at a location adjacent to the first lateral edge and a second lip wing projecting upward at a location adjacent to the second lateral edge;
- the first lip wing and the second lip wing each having a laterally asymmetric base section attached to the upper lip surface, and a bucket wing attachment section extending upwardly from the respective base section;
- a first wing shroud boss attached to an outboard side of the bucket wing attachment section of the first lip wing;
- and
- a second wing shroud boss attached to the outboard side of the bucket wing attachment section of the second lip wing.
