Implement tooth assembly with tip and adapter
A ground engaging tip of a tooth assembly for a base edge of a ground engaging implement, is provided, wherein the tooth assembly includes an adapter configured for attachment to a base edge of the ground engaging implement and having a forwardly extending adapter nose. The ground engaging tip may have a substantially keystone-shaped contour providing additional wear material at the top surface for use in top-wearing earth moving applications.
1. An adapter of a tooth assembly for a base edge of a ground engaging implement, the adapter comprising:
a rearwardly extending top strap;
a rearwardly extending bottom strap having a top surface, wherein the top strap and the bottom strap define a gap therebetween for receiving the base edge of the ground engaging implement; and
a forward extending adapter nose comprising:
a bottom surface extending forward relative to the top strap and the bottom strap,
a front surface,
a top surface,
oppositely disposed side surfaces extending downwardly from the top surface to the bottom surface, wherein the side surfaces are generally planar and are tapered in a vertical direction such that a distance between the side surfaces decreases as the side surfaces extend downwardly from the top surface toward the bottom surface,
wherein each of the side surfaces includes a projection extending outwardly therefrom.
2. The adapter of claim 1 , wherein each of the side surfaces and a vertical line define a vertical taper angle, and wherein the vertical taper angles defined by the side surfaces are equal.
3. The adapter of claim 2 , wherein the vertical taper angles defined by the side surfaces are approximately 3°.
4. The adapter of claim 2 , wherein the vertical taper angles defined by the side surfaces are approximately 6°.
5. The adapter of claim 1 , wherein the side surfaces are tapered in a horizontal direction such that a distance between the side surfaces decreases as the side surfaces extend forward from the top strap and the bottom strap.
6. The adapter of claim 5 , wherein each of the side surfaces and a line parallel to a longitudinal axis of the adapter define a longitudinal taper angle, and wherein the longitudinal taper angles defined by the side surfaces are equal.
7. The adapter of claim 6 , wherein the longitudinal taper angles defined by the side surfaces are approximately 3°.
