Problems solved by technology

[0004] Based on this, it is necessary to address the problem that the cross-section of the base of the existing main balance weight is susceptible to refrigerant resistance, and to provide a main balance weight that can reduce the resistance effect of high-pressure gas refrigerant and reduce the power loss of "wind resistance". The motor of the main counterweight, and the compressor containing said motor

Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the main balance weight, the motor and the compressor of the present invention will be further described in detail through the following embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] see Figure 5 to Figure 8 , the main balance weight 100 according to an embodiment of the present invention is used to balance the shafting of the compressor. The main balance weight 100 includes a base part 110 and a raised part 120 disposed on the base part 110 . Further, the cross-sectional shape of the base part 110 is C-shaped. The shafting of the compressor has the problem of eccentric mass, and the rotor 200 of the motor in the compressor is counterweighted through the cooperation of the raised part 120 and the...

Abstract

The invention provides a primary balance block, a motor and a compressor. The primary balance block comprises a base part and a projection part which is arranged on the base part. Both end parts of the base part are inclined surfaces. When the compressor works, a rotor of the motor is in high-speed rotation. The inclined surfaces of the base part of the rotor can buffer the resistance of a high-pressure gas refrigerant to reduce the power loss of windage. The input power of the compressor is reduced. The performance coefficient of the compressor is improved.

Description

technical field [0001] The invention relates to the field of compression equipment, in particular to a main balance weight used on a motor rotor, a motor containing the above main balance weight, and a compressor containing the above motor. Background technique [0002] At present, due to the problem of eccentric mass in the shafting of the rotary compressor, unbalanced force or unbalanced moment will be caused when the rotor of the motor rotates, and it is necessary to set up a balance weight to balance it. For a single-cylinder rotary compressor, in order to balance the force and moment caused by the eccentric mass, the mass and size of the main balance weight are relatively large, while the mass and size of the auxiliary balance weight (piece) are relatively small. see Figure 1 to Figure 4 , usually the main balance weight and the auxiliary balance weight (sheet) are manufactured separately, and then the main balance weight and the auxiliary balance weight are riveted to...
