Tip to adapter interface

Abstract

Tooth assemblies having a tip attached to an adapter by a retaining mechanism is normally utilized in order to readily replace the tip which is a high wear element. It is advantageous to have a tip that due to its interface with the adapter allows effective transfer of forces being subjected to the tip directly to the adapter without creating undesired resultant forces trying to force the tip from the adapter. In the subject arrangement, a tip has a cavity with a load bearing bottom surface at the bottom of the cavity and a pair of parallel spaced apart load bearing surfaces adjacent thereto. The tip also has an ear extending from one of the side walls thereof, a longitudinally extending groove defined therein, and a pin receiving opening 56 defined therein that extends through a top wall, the one side wall and a bottom wall of the tip and intersects the longitudinally extending groove. The adapter has a forward end which mates with the load bearing bottom surface and the pair of parallel spaced apart load bearing surfaces of the tip and has a raised lug on one side thereof which is disposed, upon assembly, in the longitudinally extending groove. A pin is forced through a pin receiving opening and contacts the raised lug to secure the tip to the adapter.
