Abstract:
An excavating tooth assembly comprising:an adapter having an outer tapered surface configured with a substantially horizontal rearward land section and a substantially horizontal forward land section, said rearward and forward land sections each having a substantially similar and generally semicircular shape, each semicircular shape including a vertical wall configured to facilitate transmission of lateral forces acting on the tooth assembly; andan excavating tooth configured for attachment to the adapter and having a hollow mounting end defining a cavity configured to mate with the adapter, said hollow mounting end including an inner tapered surface adapted to mate with said outer tapered surface of the adapter, said inner tapered surface configured with a substantially horizontal rearward transmitting section adapted to mate with said rearward land section of the adapter, and a substantially horizontal forward transmitting section adapted to mate with said forward land section of the adapter, said rearward and forward transmitting sections each having a substantially similar and generally semicircular shape complementary to the semicircular shape of the rearward and forward land sections on said adapter, with each semicircular shape on said transmitting sections of said tooth including a vertical wall configured to mate with the substantially vertical wall on the rearward and forward land sections of said adapter to facilitate transmission of the lateral forces from the excavating tooth to the adapter.
