Description
Technical field
The utility model relates to the upper support structure of a kind of rotor-type compressor stator and rotor.
Background technique
In order to improve concentricity and the system reliability of operation etc. of stator and rotor in rotor-type compressor, existing coping style is mainly the air gap adopting between clearance gauge control stator and rotor, thereby reach the motor stator object concentric with rotor, and increasing the diameter of axle of bent axle by employing, the measures such as the thickness of upper cylinder cover axle journal length, thickness and upper cylinder cover flange strengthen system reliability of operation.
Existing motor mounting process is that stator is fixed by hot jacket and housing, housing is through radio frequency heating, then by stator sleeve on housing internal diameter, housing is cooling to be held stator tightly afterwards, then rotor is put in diameter of stator bore, ensure that by clearance gauge the air gap between rotor is consistent, then the pump housing is welded on housing by upper cylinder cover or cylinder.
The compressor drum top of this structure is unsettled, has reduced system operation reliability, and high to the rigidity requirement of bent axle, and particularly to high speed and high pressure contracting machine, electromagnetism sound occurrence probability is very large, also can increase power consumption simultaneously; Stator is fixedly connected with housing, and the bad adjustment control of concentricity of stator and rotor affects the performance of compressor, and stator directly contacts with housing, and compressor operating noise is had a great impact.
Summary of the invention
Technical problem to be solved in the utility model is to provide the upper support structure of a kind of rotor-type compressor stator and rotor, this upper support structure has effectively improved the concentricity of stator and rotor in compressor and has been convenient to adjust to be controlled, improve compressor operating noise, strengthen reliability, improved the performance of compressor.
For solving the problems of the technologies described above, the upper support structure of the utility model rotor-type compressor stator and rotor comprises housing, stator, rotor, upper cylinder cover and bent axle, described upper cylinder cover is fixed in described housing, described stator is located in described housing and bottom surface is positioned at described upper cylinder cover end face, described rotor is located in described stator, this upper support structure also comprises dunnage and axle sleeve, described axle sleeve is located at described dunnage center, described dunnage is located at described stator end face and periphery is twisted and is fixed in described upper cylinder cover end face by bolt, the upper axial of described bent axle is located in described axle sleeve.
Because the upper support structure of the utility model rotor-type compressor stator and rotor has adopted technique scheme, be that this upper support structure comprises housing, stator, rotor, upper cylinder cover and bent axle, described upper cylinder cover is fixed in described housing, described stator is located in described housing and bottom surface is positioned at described upper cylinder cover end face, described rotor is located in described stator, this upper support structure also comprises dunnage and axle sleeve, described axle sleeve is located at described dunnage center, described dunnage is located at described stator end face and periphery is twisted and is fixed in described upper cylinder cover end face by bolt, the upper axial of described bent axle is located in described axle sleeve.This upper support structure has effectively improved the concentricity of stator and rotor in compressor and has been convenient to adjust to be controlled, and has improved compressor operating noise, has strengthened reliability, improves the performance of compressor.
Brief description of the drawings
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is the upper support structure schematic diagram of the utility model rotor-type compressor stator and rotor;
Fig. 2 is that the A-A of Fig. 1 is to view.
Embodiment
As depicted in figs. 1 and 2, the upper support structure of the utility model rotor-type compressor stator and rotor comprises housing 1, stator 2, rotor 3, upper cylinder cover 4 and bent axle 5, described upper cylinder cover 4 is fixed in described housing 1, described stator 2 is located in described housing 1 and bottom surface is positioned at described upper cylinder cover 4 end faces, described rotor 3 is located in described stator 2, this upper support structure also comprises dunnage 6 and axle sleeve 7, described axle sleeve 7 is located at described dunnage 6 centers, described dunnage 6 is located at described stator 2 end faces and periphery is twisted and is fixed in described upper cylinder cover 4 end faces by bolt 8, the upper axial 51 of described bent axle 5 is located in described axle sleeve 7.
This upper support structure arranges an axle sleeve at dunnage center, the upper axial of bent axle is positioned at axle sleeve, thereby effective supporting effect is played in bent axle top, so just can limit bent axle top degrees of freedom radially, make the motor of compressor become as a whole with the pump housing, fully improve the reliability of compressor operating; In the time of assembling, can first stator, dunnage and upper cylinder cover prepackage, by adjusting dunnage position, until after the concentricity of stator and rotor meets the demands, tighten the bolt between upper cylinder cover and dunnage, so stator is fixed by bolt and upper cylinder cover, dunnage is fixed by bolt and stator, form an entirety, thereby reach in the time of compressor operation, also can guarantee the concentricity of stator and rotor.
This upper support structure is applied on compressor, contrast the rotor-type compressor of hot jacket fixed stator in the past, the reliability of compressor obviously improves, when compressor operation, the air gap of rotor is more excellent, reach the concentric object of rotor, the performance of compressor is improved, and meanwhile, the compressor operating noise of upper support structure is better than conventional rotors formula compressor.
Following table is the application rotor-type compressor of this upper support structure and the performance test data table of comparisons of conventional rotors formula compressor:
As seen from the above table, when compressor high speed operation, the impact of performance of this upper support structure compressor is more excellent, this upper support structure compressor is joined the performance of A serial motors and traditional compressor, and to join the overall performance of D serial motors suitable, D serial motors is compared with A serial motors poor performance 3% left and right,, while adopting same motor and the pump housing, this upper support structure compressor performance will improve 3%.
Following table is the application rotor-type compressor of this upper support structure and the noise test data table of comparisons of conventional rotors formula compressor:
From upper watch test result, when the high rotating speed of compressor, the OA value of this upper support structure compressor roughly maintains an equal level with contrast compressor one, but lower than reduced pressure contracting machine two, noise reduction is more excellent.
