Anti-movement compressor

Abstract

An anti-movement compressor comprises a first annular magnet, a second annular magnet, a pump body assembly, a motor, a shell and a rolling bearing, the motor is arranged in the shell, the output end of the motor is connected with the pump body assembly, the end of the pump body assembly is connected with the rolling bearing, and the rolling bearing is connected to the shell; the first annular magnet abuts against the rolling bearing or the inner wall of the shell, the second annular magnet abuts against the pump body assembly or the motor, and the first annular magnet and the second annular magnet are installed in a mutual exclusion mode. The crankshaft is sleeved with the two mutually-exclusive annular magnets, one end of one annular magnet abuts against the inner ring of the rolling bearing, the other annular magnet abuts against the crankshaft or the motor rotor, and the two mutually-exclusive annular magnets apply acting force towards the auxiliary bearing to the crankshaft. According to the horizontal rotary compressor disclosed by the utility model, the end surface of the auxiliary bearing can be effectively matched with the thrust surface of the crankshaft, so that the axial movement of the compressor in a shutdown state is resisted.
