Compressor and refrigeration apparatus having compressor

Abstract

The invention discloses a compressor and a refrigeration apparatus having the compressor. The compressor comprises a housing, a motor, wherein the unidirectional bearings are respectively arranged at two sides of a rotor, a first balancing piece is arranged on the rotor, two compression mechanism parts, wherein the two compression mechanism parts comprises crankshafts and a cylinder module, each crankshaft is respectively connected with the unidirectional bearing with a corresponding side, and a second balancing piece is arranged on each compression mechanism. According to the compressor, the motor enables forward and reverse rotation, by arranging the first unidirectional bearing and a second unidirectional bearing, when the motor enables forward rotation, the first unidirectional bearing operates, when the motor enables reverse rotation, the second unidirectional bearing operates, the first unidirectional bearing enables idle running, the independent operation of two compression mechanism parts in the compressor is realized, and the compressor practicality is increased. According to the invention, a second balancing piece is arranged on two compression mechanism parts, the second balancing piece, the first balancing piece and the eccentric parts in the compression mechanism parts can realize dynamic balance, and the stable operation of the compression mechanism parts can be guaranteed.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to a compressor and a refrigeration device with the same. Background technique [0002] Since the eccentric part is provided in the compression mechanism part of the compressor, a counterweight is generally arranged on the rotor of the motor to balance the eccentric mass of the eccentric part, thereby ensuring the operation stability of the compression mechanism part. When two compression mechanism parts are arranged in the compressor, each compression mechanism part corresponds to a one-way bearing, and the independent work of the two compression mechanism parts can be realized. Since the two compressor mechanism parts share one motor, the traditional way of setting the counterweight on the motor rotor cannot balance the mass of the two eccentric parts, so that the dynamic balance of the compressor mechanism part cannot be realized, and the compressor will generate great working vibrat...
