Abstract
Eccentric screw pump with a rotor of a drive shaft circulating essentially about a fixed axis in relation to the stator in a bearing block, a power train and a screw conveyor, which revolves in a rotating-oscillating manner in a screw flight of the stator, wherein the power train provides the screw conveyor with its drive torque and the power train adjusts the differences of the motion sequences of the screw conveyor and of the drive shaft, wherein the power train consists essentially of a one-piece rotational body, which has multiple weakening recesses, which interrupt its outer circumferential jacket surface more than only insignificantly and which provide it with that reversible elasticity, which it requires in order to rotate about an axis of rotation, which curves in a periodically recurring manner at least in sections.
