Description

Rotating shaft for compressor, compressor with rotating shaft and automobile with rotating shaft

Technical Field

The utility model relates to a pivot production technical field especially relates to a compressor, car that are used for pivot of compressor and have it.

Background

The rotation of the motor rotor is converted into the rotation of the refrigerant compressing part by the rotating shaft of the compressor, and the compressor always works in a high-speed rotation state. The core pivot of present compressor comprises pivot and the pin two parts of pivot, and the pin pressure equipment is to the pivot hole in, and what lean on is the interference fit in pin and hole, and this structure can have the instability in the equipment, hardly guarantees the straightness that hangs down and the depth of parallelism of pin and pivot, if the cooperation of assembly is not good, will lead to the pivot phenomenon such as the pin drops when high-speed rotation, causes bad consequence. It becomes important to solve this problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a compressor, car that is used for pivot of compressor and has it adopts the integral type structure through pivot and pin, reduces assembly process, improves structural stability, has solved the problem that the pin easily drops when the high-speed rotation of pivot

The utility model provides a pivot for compressor, including the pivot, the pivot is circular solid of revolution, and the pivot divide into head, middle part, afterbody, pivot head end face is equipped with the pin, pin and the central line eccentric settings of pivot, and pivot and pin adoption integral type are processed.

The further improvement lies in that: the diameter of the head of the rotating shaft is R1, the diameter of the middle of the rotating shaft is R2, the diameter of the tail of the rotating shaft is R3, the diameter of the pin is R4, R2 is more than or equal to R1 and more than R3 and more than R4, R1 is phi 20mm-20.001mm, R2 is phi 20mm-20.045mm, R3 phi 11.93mm-12mm and R4 is phi 6mm-5.992 mm.

The further improvement lies in that: the joints of the head part, the middle part and the tail part of the rotating shaft adopt bent angle structures.

The utility model also provides a compressor, including above the pivot.

The utility model also provides an automobile, including above the compressor.

The utility model has the advantages that: the utility model changes the rotating shaft and the pin from an assembled type into an integral type, reduces the cost generated by the assembly process and the assembly, reduces the size deviation, can be integrally processed and then quenched to improve the strength of the rotating shaft, and has better stability; meanwhile, the size stability is good, the surface roughness is high, the processing procedures are few, and the cost is low. The compressor is stable in operation, the stability of the compressor is improved, the overall performance of the compressor is improved, and the satisfaction degree of automobile users is further improved.
