Abstract:
A drilling system includes a magnetic coupling and an oscillation absorber. The magnetic coupling has a rotor that rotates about an axis of rotation. The oscillation absorber is in operable communication with the magnetic coupling and includes an outer layer coupled to a separator layer of the magnetic coupling to form an enclosed area. An absorber shaft of the oscillation absorber is at least partially within the enclosed area and is coupled to the rotor. The absorber further includes an outer mover arranged such that rotation of the absorber shaft causes the outer mover to rotate due to interaction of inner absorber shaft magnets and outer mover magnets.
