  • Double shaft drilling apparatus with hanger bearings
    Patent number: 9309720
    Abstract: A drilling apparatus includes a housing that defines a longitudinal axis. A power section of the apparatus includes rotor adapted to move with eccentric rotary motion with respect to the longitudinal axis in response to the passage of drilling fluids through the power section. A power transmission shaft has an upper end coupled to the rotor and movable with the eccentric motion of the rotor, and a lower end constrained to rotate in a concentric manner with respect to the longitudinal axis. A generally rigid torsion rod has upper and lower ends constrained to rotate in a concentric manner, and the upper end of the torsion rod is coupled to the lower end of the power transmission shaft. A mandrel including a connection for a drill bit is interconnected with the lower end of the torsion rod such that a torque may be transmitted from the torsion rod to the mandrel to drive a drill bit.
