Abstract
Disclosed is a vibratory apparatus for a drilling apparatus comprising: a housing, a rotor operable to rotate relative to the housing, the rotor comprising one or more sets of magnets, a shuttle engaged to enable movement longitudinally, the shuttle comprising one or more follower magnets, each arranged relative to a corresponding set of magnets in the rotor, wherein each set of magnets comprises magnets arranged around the rotor with a lateral spread such that on rotation the corresponding follower magnet on the shuttle will move longitudinally to follow one or more rotating magnets of the set, thus oscillating the shuttle longitudinally.

A vibratory apparatus for a drilling apparatus comprising:
- a housing
- a rotor operable to rotate relative to the housing, the rotor comprising one or more sets of magnets,
- a shuttle engaged to enable movement longitudinally, the shuttle comprising one or more follower magnets of a first polarity, each arranged relative to a corresponding set of magnets in the rotor of a second opposite polarity,
- wherein each set of magnets on the rotor comprises magnets that are arranged around the rotor and displaced longitudinally across the rotor so that the magnets are arranged in a curvilinear sequence that curves in the longitudinal direction such that on rotation the corresponding follower magnet on the shuttle will move longitudinally due to following the curvilinear longitudinal displacement across the rotor by way of magnetic attraction of one or more rotating magnets of the set of the second polarity, thus oscillating the shuttle longitudinally.
