Abstract
The invention provides a connecting structure of compressor pump and shell, comprising compressor shell and upper bearing on the compressor mechanical part. There are screw holes set on the peripheral part of said upper bearing in mean space. Cone circular hole is set on the position of said shell relative to said screw hole on the upper bearing and bolt is screwed into said screw hole of upper bearing through said circular hole. Sealing surface is formed between shell screwed by bolt and bolt and shell is fixed to the upper bearing. Said screw is the one with cone surface. The benefit of the invention is that by the connecting structure of compressor pump and shell, thermal stress generated by uneven heating during welding process is avoided; shell deformation by welding heat is prevented by bolt screwed out of the shell; leakage of cool medium is avoided. Compared with original three-point welding technology it is provided with higher machining efficiency and improves the quality of compressor production.
Description
Technical field
The invention provides a kind of compressor pump and casing connecting structure.
Background technique
In general, compressor is a kind of machine of compressed fluid.This compressor is by the seal container with certain inner space, is installed in the electromechanical part that can produce driving force in the seal container and can utilizes the driving force of electromechanical part and the compression mechanical portion of compressed fluid constitutes.Fig. 1 is the rotary compressor longitudinal construction sectional drawing of prior art.As shown in Figure 1, the seal container of this rotary compressor equidistantly is formed with the cylindrical housing 1 of three welding holes and loam cake and lower cover by the bottom along its circumference and constitutes.One side of shell 1 is provided with the refrigerant import, and the center portion of loam cake then is provided with refrigerant exit.The electromechanical part on seal container top mainly by be fixed on the cylindrical housing inwall stator and the center of stator and can by and stator between the rotor that is rotated of electromagnetic action form.The compression mechanical portion that is positioned at the seal container bottom then mainly comprises cylinder and is installed in the upper bearing and the lower bearing of cylinder upper and lower end face respectively.Bent axle runs through the center of rotor and cylinder, and it can together rotate with rotor, thereby the rotating force that electromechanical part produces can be passed to compression mechanical portion.The bottom of bent axle is formed with eccentric part, the outside of eccentric part then be with can be rotated in the inside cavity of cylinder and compressible refrigerant roll ring.Because the center of gravity of rolling ring does not overlap with the rotating center of bent axle, thus the power energy imbalance can appear during high speed rotating when bent axle in compressor, thus become the vibrative main cause of compressor.In order to address this problem, to add in the upper end portion of rotor usually and load onto equilibrium block and come trimming moment.But there is following point in this rotary compressor: compression mechanical portion is to adopt three spot welding connections by three welding holes that form on housing 1 peripheral wall housing 1 and upper bearing directly to be welded together, because the input of the welding heat of this connecting means is bigger, thereby upper bearing and cylinder easily produce thermal distortion, and weld strength and quality are all bad, thereby might cause problems such as coolant leakage and moving element friction, therefore can influence the performance of compressor.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the purpose of this invention is to provide a kind of compressor pump and housing linkage structure, adopt screw to twist to connect compressor pump is connected with housing, avoided leakage, and speed is very fast, the manufacturing equipment condition is simple.
For achieving the above object, the technical solution used in the present invention provides a kind of compressor pump and housing linkage structure, includes the upper bearing of compressor housing and compressor Machinery Ministry, wherein:
On the periphery of described upper bearing, be provided with at interval uniform screw hole, be provided with conical surface circular hole at described housing and described upper bearing screw hole corresponding section, the circular hole that passes on the described housing by screw is screwed in the described upper bearing screw hole, between housing that screw passes and screw, form sealing surface, and housing is fixed on the upper bearing.
Described screw is the screw that has the conical surface under the nut of described screw.
Effect of the present invention is to adopt compressor pump and housing linkage structure, avoided in the original welding process because the uneven thermal stress that produces of being heated, because utilized screw to be screwed into from the outside of housing, prevented to cause the distortion of housing owing to welding heat, stopped the generation of coolant leakage.Compare with former three spot welding technologies, higher work efficiency is arranged, and improved the quality of compressor product.

Embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated compressor pump of the present invention and casing connecting structure.
Shown in Fig. 2,3,4, the structure of compressor pump of the present invention and casing connecting structure is the upper bearing that includes compressor housing and compressor Machinery Ministry, on the periphery of described upper bearing 3, be provided with at interval uniform screw hole, be provided with conical surface circular hole 6 at described housing 2 with described upper bearing screw hole corresponding section, the circular hole that passes on the described housing 2 by screw 5 is screwed in the described upper bearing screw hole, between the conical surface circular hole 6 of the housing that screw 5 passes and screw 5, form sealing surface, and housing 2 is fixed on the upper bearing 3.Described screw 5 is to select the screw that has the conical surface under the nut for use.
The structure of compressor pump of the present invention and casing connecting structure is to realize like this.
At first, process screw hole on the periphery with the upper bearing 3 of the fixing compressor pump housing, screw hole evenly is no less than three holes at interval, and this determines according to the axis of a cylinder bearing structure.Then, process conical surface circular hole 6 at described housing 2 with upper bearing screw hole corresponding section, the conical surface circular hole 6 that passes on the described housing 2 by screw 5 is screwed in the described upper bearing screw hole, between the conical surface circular hole 6 of the housing that screw 5 passes and screw 5, form sealing surface, because used screw 5 is to select the screw that has the conical surface under the nut for use, fit with the circumference of the conical surface circular hole 6 of housing.Like this housing 2 is fixed on the upper bearing 3, technological operation is simple, quick, fastness is reliable.
Claims (2)
