Description
Technical field
The utility model relates to compressor, especially relates to a kind of compressor upper support structure.
Background technique
In order to improve the concentricity of stator and rotor and the reliability etc. of system cloud gray model in rotor-type compressor, existing coping style mainly adopts the air gap between clearance gauge control stator and rotor, thus reach the motor stator object concentric with rotor, and by adopting the diameter of axle increasing bent axle, the measures such as the thickness of upper cylinder cover axle journal length, thickness and upper cylinder cover flange strengthen the reliability of system cloud gray model.
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 inner diameter, after housing cooling, stator is held tightly, then rotor is put in diameter of stator bore, ensure that the air gap between rotor is consistent by clearance gauge, then the pump housing is welded on housing by upper cylinder cover or cylinder.
The compressor drum top of this structure is unsettled, reduces system operation reliability, and high to the rigidity requirement of bent axle, and particularly to compressor when running up, electromagnetism sound occurrence probability is very large, also can increase power consumption simultaneously; Stator is fixedly connected with housing, and bad adjustment of the concentricity of stator and rotor controls, and affect the performance of compressor, and stator directly contacts with housing, has a great impact compressor operating noise.
In order to solve the problem, existing compressor is provided with upper support structure, and as shown in Figure 1, described upper support structure is made up of bearing support 2, supporting frame 3, bearing 4 and fixing bolt 1.Supporting frame 3 is by being welded to connect in compressor housing 8, and bearing 4 is embedded in bearing support 2, and adopt bolt 1 to fix between bearing support 2 and supporting frame 3, bent axle 5 stretches in bearing 4.This structure effectively improves the concentricity of stator and rotor in compressor and is convenient to adjust and controls, and improves compressor operating noise, enhances reliability, improves the performance of compressor.But said structure also exists following problem: bent axle is long, the long meeting of bent axle causes the difficulty of processing aspect.Bent axle is longer, the more difficult processing of central hole of the crankshaft; Bent axle is longer, and the straightness accuracy after the processing of bent axle major axis is poorer.Also may need in addition to be equipped with the larger equipment of processing stroke, cause Crankshaft Machining cost increase.
Summary of the invention
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and the compressor upper support structure that a kind of Crankshaft Machining is easy, precision is high, cost is low is provided.
The purpose of this utility model can be achieved through the following technical solutions: a kind of compressor upper support structure, described compressor comprises bent axle, rotor, motor stator, housing, described upper support structure comprises bearing support, supporting frame, bearing, wherein, described bearing is embedded in rotor, and described bearing support top is connected with supporting frame, and bottom is inserted in bearing, described bent axle is arranged in rotor, and is positioned at bearing support bottom part down.
Further, the cross section of described bearing support is T-shaped, and its top perimeter is erected on supporting frame, and is connected by fixing bolt, and the interior bearing with embedding this center hole of center hole stretching into rotor bottom it is connected.
Further, described bearing is positioned at the center hole top of electronics rotor.
Further, the described bearing support length stretched in rotor is not less than bearing support base diameter.
Further, described bearing exists with bearing support cooperation place and coordinates radial clearance, and monolateral gap is not higher than 10% of rotor air gap.
Further, described supporting frame is welded on compressor housing.
Compared with prior art, bearing support stretches in rotor by the utility model, can play and limit the centrifugal displacement of rotor when running up, thus control the concentricity of stator and rotor, ensure that the performance of compressor, bearing support stretches in rotor simultaneously, replace original part bent axle, therefore the length of bent axle significantly shortens, and Crankshaft Machining is easy, machining accuracy is high, and processing cost is lower.
Accompanying drawing explanation
Fig. 1 is existing compressor upper support structure schematic diagram;
Fig. 2 is the utility model compressor upper support structure schematic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
