Embodiment Construction

[0028] In each following embodiment of the present invention, all take Image 6 The horizontal direction in is the horizontal direction, Image 6 The vertical direction in is described as the vertical direction, which is only for the convenience of describing the structure, and does not limit the structure to be protected by the present invention.

[0029] see in conjunction Figure 1 to Figure 6 As shown, according to the embodiment of the present invention, a balance assembly is provided. The balance assembly includes a first balance piece 10 for fixing on the rotor 2 and a handle for adjusting the balance assembly that can be assembled on the first balance piece 10. The weight and / or the second balance of the distance from the center of gravity of the assembly to the centerline of rotation of the rotor 2 . The present invention can adjust the weight of the balance assembly and / or the distance between the center of gravity of the balance assembly and the center line of rot...

Abstract

The invention provides a balance assembly, a rotor assembly and a compressor. The balance assembly comprises first balance pieces used for being fixed to a rotor and second balance pieces which can beassembled to the first balance pieces and used for adjusting the weight of the balance assembly and/or the distance from the gravity center of the balance assembly to a rotating center line of the rotor. According to the balance assembly, the rotor assembly and the compressor, due to the fact that the first balance pieces are provided with the second balance pieces which can adjust the weight ofthe balance weight and/or the distance from the gravity center of the balance assembly to the rotating center line of the rotor, when the balance assembly is assembled to the rotor, the number and theassembling manner of the first balance pieces and the second balance pieces can be adjusted according to the weights of the crank shaft eccentric part and the roller part of the rotor assembly and the distance from the gravity center of the eccentric part to the rotating center line of the rotor, and the balance coefficient design target is achieved. According to the balance assembly, the balanceassembly can be adjusted according to the demands of the rotor assembly, and therefore the balance assembly is universal and suitable for different types of compressors.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a balance assembly, a rotor assembly and a compressor. Background technique [0002] The compressor needs to design an eccentric part on the crankshaft to realize the function of the compressor, and the center of gravity of the eccentric part of the crankshaft and the roller part has a certain distance from the rotation axis of the crankshaft. When the compressor is running, the eccentric part of the crankshaft and the roller part will produce An unbalanced rotating centrifugal force. [0003] In order to eliminate the adverse effect brought by the mass of the eccentric part of the crankshaft and the roller part (centrifugal force and the moment generated by the centrifugal force), two parts of balance weights are usually installed on the upper and lower sides of the compressor motor rotor to offset the crankshaft when the compressor is running. Centrifugal force...
