Problems solved by technology

[0007] If the capacity of the compressor with the balance weight is large, the weight of the balance weight is relatively heavy, which will cause the deformation of the rotor 35. Such deformation of the rotor 35 will hinder the rotation of the rotor 35, resulting in a loss of motor performance.

Abstract

The invention discloses a rotary balance device of a hermetic scroll compressor, which belongs to an arc engagement rotary piston pump. The invention comprises a drive motor which is arranged inside a shell to generate rotary force; a compression mechanism part which is arranged on a rotational axis of the drive motor and combined with an eccentric part to compress refrigerant; at least more than one balance device which are arranged to counterbalance the rotary imbalance generated on the eccentric part while the rotational axis conducts the rotary motion, wherein, the balance device comprises a main body part which has appointed weight and a combining part which leads the main body part to be combined on the rotational axis, moreover, the balance device is combined with the rotational axis. Therefore, stators of the invention can stably rotate, and the performance loss of the motor can be avoided, thereby providing the compressor with higher reliability.

Description

technical field [0001] The present invention relates to an arc meshing type rotary piston pump, more specifically, it is a rotary balance device for a hermetic scroll compressor which is used to counteract the unbalanced rotation on the eccentric part and prevent the performance loss of the motor. Background technique [0002] figure 1 It is a schematic diagram of the longitudinal section structure of the conventional hermetic scroll compressor; figure 2 yes figure 1 Schematic enlarged longitudinal section of the balance weight combination structure. As shown in the figure, the compressor includes a casing 11 with a sealed storage space inside, and a compression mechanism part 21 that compresses refrigerant inside the casing 11 is housed inside the casing 11 to provide driving force for the compression mechanism part 21. motor. [0003] One side of the casing 11 is equipped with a suction pipe 13 and a discharge pipe 15 for sucking and discharging the refrigerant, and i...
