A double support internal meshing rotor mechanism suitable for gas working substance

Abstract

The application discloses a double-support inner meshing rotor mechanism suitable for gas working medium, which comprises an inner rotor and an outer rotor. The inner rotor and the outer rotor are matched through inner meshing curves, and the rotating centers of the inner rotor and the outer rotor are eccentrically arranged to form a periodically changed sealed chamber. The inner rotor is independently supported on a mechanism shell through an inner rotor supporting bearing of the inner rotor, and the outer rotor is independently supported on the mechanism shell through an outer rotor supporting bearing of the outer rotor, so that the inner rotor and the outer rotor are independent in spatial position. The inner rotor and the outer rotor are gap-matched, and there is no direct solid contact between the inner rotor and the outer rotor during the working process. The double-support inner meshing rotor mechanism further comprises an independent force transmission assembly. The force transmission assembly comprises a force transmission inner structure coaxially fixedly connected with the inner rotor and a force transmission outer structure coaxially fixedly connected with the outer rotor. The force transmission inner structure and the force transmission outer structure are meshed or contacted with each other, and are used for transmitting meshing torque between the inner rotor and the outer rotor. The double-support inner meshing rotor mechanism has the advantages of improving operation stability, service life and efficiency, and reducing maintenance cost.
