Rotor with damping structure and compressor

The invention discloses a rotor with a damping structure and a compressor, and aims to solve the dynamic problem of a slender shaft rotor of a high-speed multi-stage compressor. A blind hole is formed in the middle of the end face of a shaft head of the rotor, the shaft end is detachably connected with the shaft head, the damping ring is arranged on the shaft head through a ring bush, the damping ring shell is arranged outside the damping ring, the damping ring shell, the shaft head blind hole and the damping ring form a transition cavity, a first oil way is formed in the bearing body, and a second oil way is formed in the damping ring. A third oil way is formed in the side wall of the shaft head end face blind hole, the first oil way, the second oil way and the third oil way are communicated, and an outlet of the second oil way is located at the ring lining. The compressor comprises a compressor shell, the rotor with the damping structure is located in the compressor shell, and a supporting bearing is arrang
