A method for producing a pendulum of a pendulum slide cell pump, comprising:
- providing a prefabricated pendulum body, and performing a post-machining operation on the pendulum body only at a plurality of contact locations at which the pendulum body contacts at least one of an inner rotor and an outer rotor of the pendulum slide cell pump.
A pendulum for a pendulum slide cell pump, comprising:
- a prefabricated pendulum body defining an outer contour and a plurality of contact locations disposed about the outer contour at positions, which the pendulum body contacts at least one of an outer rotor and an inner rotor;
- wherein the plurality of contact locations are post-machined as compared to a region of the outer contour spaced away from the plurality of contact locations.
A pendulum slide cell pump comprising:
- an inner rotor connected to an outer rotor via at least one pendulum, the at least one pendulum including:
- a prefabricated pendulum body defining an outer contour;
- a plurality of contact locations disposed about the outer contour and spaced apart from one another, the plurality of contact locations respectively defined by a portion of the pendulum body that contacts at least one of the inner rotor and the outer rotor;
- wherein the outer contour is post-machined only at the plurality of contact locations compared to a region of the outer contour spaced away from the plurality of contact locations.
