Frame of hermetic compressor

Abstract

The invention is about a frame of closed type compressor. It comprises parts as follows: a frame main body made of sheet material; bended linking leg part on two ends of the main body which is formed in one piece with the main body; a fixing plate on the front end of the linking leg part, extended along the outer direction of the linking leg part and bended; bending part arranged on the frame main body and linked to the fixing plate and linking leg part, and a reinforced rib making the sheet material concave on one side and convex on the other side by forcing. The invention can improve the strength of the linking leg part and the whole frame, reduce the weight of the whole frame and simplify the making procedure.

Description

technical field [0001] The invention relates to a hermetic compressor in the general engineering field, in particular to a hermetic compressor installed inside a hermetic container on which various accessories constituting the compressor are fixed, which can improve the strength of the machine frame and at the same time Frame for hermetic compressor that reduces the weight of the frame and simplifies the manufacturing process. Background technique [0002] see figure 1 Shown is a schematic cross-sectional view of the internal structure of an existing common compressor according to the prior art. As shown in the figure, the above-mentioned existing common compressor mainly includes the following structural components: [0003] An airtight container 1 composed of an upper container 1 t and a lower container 1 b is provided with a frame 2 attached to the inside of the airtight container 1 . A stator 3 is fixed on the frame 2, and the frame 2 is arranged inside the airtight c...

AI Technical Summary

Problems solved by technology

[0011] However, in the prior art, the connecting legs 16 formed at both ends of the frame 15 are relatively weak in strength.

That is, the strength of the above-mentioned upper and lower ends of the connecting legs 16 bent at right angles is particularly weak, and therefore, the distance between the connecting legs 16 at the two ends may be short or long during installation or operation.

In order to solve the above problems, it is generally to select thicker materials to make the frame 15, but this will not only increase the weight of the frame 15, but also be unfavorable for its manufacturing process.

[0012] In addition, if the strength of the above-mentioned frame 15 cannot be ensured, deformation will easily occur when components such as the cylinder portion 6 or the stator 3 are fixed to the frame 15, thereby the air gap between the stator 3 and the rotor 4 cannot be accurately formed ( Air Gap)

In addition, during the operation of the compressor, because the above-mentioned frame 15 will undergo elastic deformation, the relative positions of the various components fixed on the frame 15 will be changed, thereby increasing the wear and noise of the components.

[0013] This shows that the frame of above-mentioned existing hermetic compressor still has many defects, and urgently needs to be further improved
