Problems solved by technology

The stator of the motor is fixed on the mounting surface of the cylinder base by screws. There are still flatness tolerances on the mounting surfaces of the three mounting columns of the cylinder base. The existence of these dimensional and shape tolerances leads to inaccurate design of the clearance value of the motor stator and rotor. If it is too small, otherwise it may lead to failure of assembly or sweeping of the stator and rotor bore after processing, which limits the energy efficiency of the compressor to a certain extent.

Embodiment Construction

[0029] see in conjunction Figure 1 to Figure 3 As shown, a cylinder block according to an embodiment of the present invention includes:

[0030] Cylinder seat body 1;

[0031] The stator core 2 is integrally formed with the cylinder block body 1 .

[0032] The cylinder block of the present invention solves the problem of low assembly precision between the cylinder block and the stator core 2, and restricts the design of the gap value between the stator core 2 and the motor rotor 3, and the cylinder block main body 1 and the stator core 2 are integrally formed, reducing parts Quantity, the cylinder seat does not need to be machined to assemble the mounting surface, and there is only one machining error. The motor using this type of cylinder seat has higher installation accuracy, and the gap between the stator and the rotor can be designed to be smaller, without worrying that the stator and the rotor cannot Assembling or the problem of stator and rotor sweeping occurs, so tha...

Abstract

The invention provides a cylinder block and a compressor. The cylinder block comprises a cylinder block body (1) and a stator core (2), and the stator core (2) is integrally formed with the cylinder block body (1). The cylinder block solves the problem that the assembly precision of the cylinder block and a motor stator is low and the design of motor stator and rotor gap values is restricted, thereby limiting the improvement of the energy efficiency of the compressor.

Description

technical field [0001] The invention belongs to the field of air-conditioning equipment, and in particular relates to a cylinder block and a compressor. Background technique [0002] Refrigerator compressors currently on the market generally use a reciprocating crankshaft-connecting rod mechanism, including cylinder blocks, crankshafts, connecting rods, piston pins, pistons, valve groups, motor stators, motor rotors, support springs, and housings. The piston is installed in the cylinder hole of the cylinder block, the motor stator is fixedly connected with the cylinder block, and the motor rotor is fixedly connected with the crankshaft. When the compressor is running, the motor rotor drives the crankshaft to rotate, and the connecting rod drives the piston to reciprocate. Wherein the motor stator and the cylinder base are fixedly installed on the three mounting columns on the cylinder base through screws and screw gaskets. In order to ensure the stable operation of the com...
