摘要： An improved drive train for a progressive cavity device is disclosed. The progressive cavity device has a rotor, a stator, means for fluid to enter between said stator and rotor, and means for fluid to exit therefrom. The rotor is adapted to roll with respect to the stator. The improved drive train comprises means attached to the rotor, for rotation substantially about a single axis, whereby the rolling of said rotor and the rotational motion about said single axis are directly connected and are at different speeds. At least a portion of said means attached to the rotor is aligned with the true center of the rotor.
