Abstract
The invention relates to a shell structure of an oil-free air compressor, which comprises a shell body, a shell supporting part and a cylinder supporting part, wherein the shell supporting part and the cylinder supporting part are connected to the outer surface of the shell body and are integrally formed with the shell body; the cylinder sleeve supporting parts are uniformly distributed at four corners; the invention is used for the oil-free air compressor, has simple structure, convenient installation and good heat dissipation, is beneficial to improving the production efficiency, prolonging the service life of the product and reducing the cost.
Description
Technical Field
The invention relates to the technical field of compressor shells, in particular to a shell structure of an oil-free air compressor.
Background
At present, a common large-stroke swinging piston type oil-free air compressor in the market selects a smaller connecting rod ratio for ensuring the sealing of a piston in the operation process, and the length of the connecting rod is very long due to a larger eccentric distance. The long metal pipe is used as an effective support for connecting the shell and the valve plate, the volume clearance of the compressor is guaranteed, and the metal pipe is hollow and used for fastening the cylinder cover, the valve plate and the shell through bolts. Because the distance between the shell and the valve plate is long, the length of the cylinder is long. The structure is simple, so the compressor is widely applied to the existing compressor, but because the cylinder cover, the valve plate and the shell are fastened by more bolts for one compressor, generally, 8-12 bolts are used, and therefore, the production efficiency is low. And because the cylinder is longer, the heat in the cylinder outside the piston cavity is difficult to dissipate, the temperature of the cylinder is higher, and because the piston ring is formed by processing polytetrafluoroethylene, the degradation speed of the polytetrafluoroethylene is accelerated along with the temperature rise, so the service life of the piston ring is shortened due to the high temperature of the cylinder.
Disclosure of Invention
The invention aims to solve the defects of the prior art and provides a shell structure of a compressor, which has the advantages of simple structure, convenience in installation and good heat dissipation.
The invention adopts the following technical scheme to realize the purpose: the utility model provides an oilless air compressor's shell structure, includes casing main part, casing supporting part and cylinder supporting part are connected on the casing main part surface, with casing main part integrated into one piece, the casing main part is the cylinder, a plurality of ventilation windows have been seted up in the casing main part, the both sides of casing supporting part are provided with a plurality of strengthening ribs, a plurality of louvres have been seted up on the upper portion of casing supporting part both sides, the top of casing supporting part is the valve plate supporting part, is connected with oilless air compressor's valve plate bottom surface.
The cylinder sleeve supporting parts of the shell are uniformly distributed at four corners.
The invention adopts the technical proposal to achieve the following beneficial effects:
the supporting part and the shell body are integrally cast, the structure is simple, the original shell lengthened metal tube structure is replaced, the number of assembly parts is greatly reduced, the assembly efficiency is improved, and the cost is reduced.
The outer side of the support part of the shell is provided with the plurality of reinforcing ribs, so that the overall structural strength of the shell is improved, and the shell cannot deform due to the screw locking force during subsequent bolt assembly.
The shell integrally lengthens the cylinder supporting part, the length of the cylinder is reduced, the side surface of the cylinder body supporting part of the shell is provided with the plurality of radiating holes, the radiating performance is improved, the temperature of the cylinder is reduced, and the service life of a piston ring is prolonged.

Detailed Description
The invention is described in further detail below with reference to the figures and the examples.
As shown in fig. 1, 2 and 3, the casing structure of the oil-free air compressor according to the present invention includes a casing main body 15, a casing supporting portion 11 and an air cylinder supporting portion 12, wherein the casing supporting portion 11 and the air cylinder supporting portion 12 are connected to an outer surface of the casing main body 15 and are integrally formed with the casing main body 15, the casing main body 15 is a cylindrical body, a plurality of ventilation windows are formed on the casing main body 15, a plurality of reinforcing ribs 14 are disposed on both sides of the casing supporting portion 11, a plurality of heat dissipation holes 13 are formed on upper portions of both sides of the casing supporting portion 12, and a valve plate supporting portion 16 is disposed at a top end of the casing supporting portion 12 and is connected to a bottom surface of a.
As shown in fig. 4, the oil-free air compressor housing of the present invention has a schematic top view structure; the extension of the cylinder support portion 12 of the housing 1 reduces the height of the cylinder and reduces the cost. Meanwhile, the cylinder supporting parts 12 of the shell 1 are uniformly distributed at four corners, and the space outside the four corners forms an airflow passage, so that the heat inside the cylinder 2 outside the piston cavity is easily dissipated, the temperature of the cylinder is reduced, and the service life of the piston ring is prolonged.
A plurality of radiating holes 13 are distributed on two sides of the shell supporting part 11, so that heat between the cylinder 2 and two sides of the shell supporting part 11 is easy to radiate, the temperature of the cylinder is further reduced, and the service life of the piston ring is prolonged.
The above embodiments are only for illustrating the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby, and any modification made on the basis of the technical scheme according to the technical idea proposed by the present invention falls within the protection scope of the present invention; the technology not related to the invention can be realized by the prior art.
