摘要： An adapter includes a first leg, a second leg, and a throat portion that define a slot defining a direction of assembly onto a work implement assembly, a lateral direction that is perpendicular to the direction of assembly, and a vertical direction that is perpendicular to the direction of assembly and the lateral direction. The throat portion further includes a first throat side surface disposed along the lateral direction and a second throat side surface disposed on the opposite side of the throat portion along the lateral direction. The first throat side surface defines a first adapter cover receiving recess.

摘要： An adapter includes a first leg, a second leg, and a throat portion at least partially define a slot that defines a projection at the closed end of the slot that includes a flat middle portion straddled laterally by a first arcuate portion and a second arcuate portion, defining a lateral middle portion width. A projection protruding distance is measured along the direction of assembly from the closed end of the slot to the flat middle portion. The projection protruding distance ranges from 0.8 to 1.2 multiplied by the lateral middle portion width.

摘要： A tooth assembly having an adapter, a tooth, and a pin. The adapter and the tooth each have a first portion and a second portion. The first portion of the adapter is adapted to be combined with an earth-digging implement. The second portion of the adapter is adapted to be combined with the tooth. The second portion of the adapter has an opening adapted to receive an engagement member extending from the second portion of the tooth. The first portion of the tooth is adapted to engage the material being displaced by the implement and the second portion is adapted to be combined with the adapter. The second portion of the tooth has an opening adapted to receive an engagement member extending from the second portion of the adapter. The pin is inserted through openings in both the adapter and the tooth to secure the two components together during operation.

摘要： A tooth adaptor for a leading edge of excavation equipment has a body having legs defining a cavity, the body adapted to be mounted to the excavation equipment by the leading edge received in the cavity. A tooth interface is at a leading end of the body, a contact surface of the body being defined in the cavity and being configured to be opposite a leading surface of the leading edge and in contact with the leading surface. A boss projects in a trailing direction from the contact surface, wherein at least one of contact surfaces including a slot extending in a leading-to-trailing direction of the tooth adaptor. The slot may define a flaring section in which sidewalks) of the slot diverges from the leading-to-trailing direction. A trailing surface(s) at an end of the legs has a flaring geometry flaring away from the tooth interface.
