Abstract
A tip defining a cavity for being attached to a work implement comprises a body that defines a cavity with a cavity upper flat portion length ranging from 5 mm to 20 mm, or a cavity side transition surface configured to avoid interference with a tip adapter, or a cavity first lower planar surface that forms an oblique angle with the cavity second lower planar surface.
Claims10
A tip defining a cavity for being attached to a to a work implement, the tip comprising:
- a body including a closed end and an open end;
- a forward working portion disposed proximate the closed end;
- and
- a rearward connecting portion disposed proximate the open end, the rearward connecting portion defining a cavity extending from the open end toward the closed end, the cavity including a plurality of surfaces defining a direction of assembly and the tip defines a Cartesian coordinate system having a X-axis, Y-axis and a Z-axis and defining a X-Y plane, a X-Z plane, and a Y-Z plane, wherein the X-axis is parallel with the direction of assembly:
- wherein the cavity is defined by a cavity upper surface, a cavity lower surface and a cavity side surface extending substantially from the cavity upper surface to the cavity lower surface, the cavity side surface including a cavity side transition portion configured to avoid interference with a tip adapter and the cavity is further defined by a side bearing surface and the cavity side transition portion includes a planar portion disposed proximate the open end and a radial portion blending the planar portion to the side bearing surface along the direction of assembly.
