摘要： A composite flexible torsion bar coupling is used to connect the orbiting rotor of a Moineau-type motor to the concentrically rotating output drive shaft. The two-piece torsion bar coupling is hollow, to allow fluid passage through the rotor. This permits large quantities of fluid flow through the bit without passing all the fluid through the motor. The torsion bar is connected to the rotor at an inside surface adjacent to a power-producing surface of the rotor. This configuration provides the shortest possible coupling distance, thereby considerably reducing the overall length of the motor without decreasing its power output.
