Claims16
A system for coupling equipment components, the system comprising:
- a tooth point;
- an adapter comprising a recess formed therein;
- and
- a magnetic coupling assembly configured to couple the tooth point to the adapter, the magnetic coupling assembly configured to be received at least partially within the recess formed in the adapter, and the magnetic coupling assembly comprising:
- an insert configured to be placed within the recess of the adapter, the insert comprising a first internal recess;
- and
- a magnetic coupler configured to be received within the first internal recess of the insert, the magnetic coupler comprising:
- a magnetic core comprising a magnetic material;
- and
- a shield at least partially enclosing the magnetic core, the shield substantially preventing magnetic attraction between the magnetic core and the tooth point.
