Abstract
The apparatus has a housing which is secured to the lower end of a drilling motor body and carries an arbor that is secured to the output shaft of the motor. The arbor has three segments serially connected by gimbals. The upper segment is axially fixed by the bearings of the motor and has a lower end that extends when actuated to push the center segment downward. Axial movement of the center segment actuates a cam to move it laterally. The lower segment extends from the housing as an output shaft. It is arranged to tilt relative to the housing and its upper end is moved laterally by the gimbal connected center segment. The resulting tilt of the rotating axis of the output shaft causes an attached drill head to drill a deflected well bore.
