Abstract
The invention discloses an auxiliary bearing structure for a magnetic levitation motor. The auxiliary bearing structure comprises a rotor, a housing, a base, a lower auxiliary bearing bracket, a pressing plate and an auxiliary bearing. The housing is connected with the base through screws. The lower auxiliary bearing bracket is connected with the base through screws. The auxiliary bearing is arranged in the lower auxiliary bearing bracket. The pressing plate is connected with the lower auxiliary bearing bracket through screws and fixes the auxiliary bearing into the lower auxiliary bearing bracket. The rotor is rotatably arranged in the auxiliary bearing. The auxiliary bearing structure for the magnetic levitation motor has a simple structure and the bearing is directly mounted in the lower auxiliary bearing bracket. The auxiliary bearing structure has advantages of simple and reliable mounting, and high convenience in detachment.
