Problems solved by technology

[0002] The current rotor compressor housing and the upper cylinder head are two parts, which need to be welded to fix them together. During the installation process, when the upper cylinder head is welded or assembled, the concentricity is not easy to ensure, which will affect the performance of the compressor. A certain influence makes the working efficiency of the compressor decrease, and the gap between the stator and the rotor is not very uniform

Embodiment 1

[0018] like figure 1 As shown, the integrated design of the rotor compressor structure includes an upper shell cover 1, a stator 2, a rotor 3, a crankshaft 4, an integrated frame 5, a cylinder 6, a piston 7, a lower cylinder cover 8, and a lower shell cover 9. The air intake connecting pipe 10, the upper part of the integrated frame 5 is connected with the upper shell cover 1, and the lower part is connected with the lower shell cover 9, and fixed by laser welding. The upper part of the integrated frame 5 is provided with a ring Groove 51, the bottom of stator 2 falls in annular groove 51, crankshaft 4 and piston 7 are integrated, integral frame 5 is by metal material, such as cast iron (FC250) by one-shot molding.

Embodiment 2

[0020] see figure 1 , an integrally designed rotor compressor structure, wherein the upper part of the integrated frame 5 is connected to the upper casing cover 1, and its lower part is connected to the lower casing cover 9 and fixed by glue, and the rest of the structure is the same as that of the embodiment 1 is the same.

Abstract

The invention relates to an integratedly designed rotary compressor structure which comprises an upper shell cover cap, a stator, a rotor, a crankshaft, a shell, an upper cylinder cover, a cylinder, a piston, a lower cylinder cover, a lower shell cover cap and an air inflow connecting pipe, wherein, the upper cylinder cover and the shell are rolled into one and formed an integrated frame through one-shot forming. Compared to the prior art, the invention has the following advantages: a gap between the stator and the rotor is uniform, coaxial parts have good coaxiality, etc.

Description

technical field [0001] The invention relates to a rotor compressor, in particular to an integrally designed rotor compressor structure. Background technique [0002] The current rotor compressor housing and the upper cylinder head are two parts, which need to be welded to fix them together. During the installation process, when the upper cylinder head is welded or assembled, the concentricity is not easy to ensure, which will affect the performance of the compressor. A certain influence makes the working efficiency of the compressor decrease, and the gap between the stator and the rotor is not very uniform. Contents of the invention [0003] The object of the present invention is to provide an integrated rotor compressor structure with relatively uniform clearance between stator and rotor and good coaxiality between coaxial components in order to overcome the above-mentioned defects in the prior art. [0004] The purpose of the present invention can be achieved through th...
