Flexible support structure between portion's movement and shell.
Background technology
Refrigeration compressor is installed on domestic or commercial refrigerator or refrigerator.When work, refrigerant is by air intake duct, air-breathing
Muffler, cylinder, discharge chamber, interior comb, exhaust pipe enter refrigeration system.In this process, piston can move back and forth,
To make movement generate vibration, vibration is transmitted to shell along the support construction of movement and interior comb respectively.Existing movement support knot
Structure generally comprises gasket, upper bushing, spring, lower bushing and stud, and movement is mainly subtracted by spring along the vibration of support construction
It shakes.In general, technical staff reduces the vibration of compressor by adjusting the rigidity of spring and interior comb.But with spring rate
It reduces, the displacement that movement occurs when startup is increasing, and compressor can occur when serious and hit shell phenomenon.
Invention content
The technical problem to be solved by the utility model is to propose that one kind is laid between compressor movement and shell, lead to
It while the support stiffness for reducing movement is crossed to reduce vibration of compressor, and can avoid that the compressor that compressor hits shell phenomenon occurs
Movement flexible support structure.
In order to solve the above technical problems, a kind of compressor movement flexible support structure of the utility model includes gasket, elasticity
Element, upper bushing, lower bushing and stud, the gasket are set to the upper end of the upper bushing, and the lower bushing is placed on the stud
On, the lower part of the elastic element is placed on the lower bushing, and the upper bushing is inserted into the top of the elastic element, it is described on
There are overlapping region, the lower part of the upper bushing and the tops of the lower bushing to exist for the lower part of bushing and the top of the lower bushing
There are certain intervals in overlapping region.
The intermediate region of a kind of above-mentioned compressor movement flexible support structure, the elastic element is in corrugated tube shape, described
Elastic element is equipped with gas vent on the top of intermediate region.
The bottom of a kind of above-mentioned compressor movement flexible support structure, the lower bushing is equipped with oil leaking hole.
A kind of above-mentioned compressor movement flexible support structure, the largest cross-sectional sized of the lower edge outer ring of the upper bushing
Less than the smallest cross-sectional size of the top edge inner ring of the lower bushing.
A kind of above-mentioned compressor movement flexible support structure, the smallest cross-sectional size of the lower edge inner ring of the upper bushing
More than the largest cross-sectional sized of the top edge outer ring of the lower bushing.
A kind of above-mentioned compressor movement flexible support structure, the elastic element are made of high damping material.
A kind of above-mentioned compressor movement flexible support structure, the elastic element are metal spring.
Plastic material system is respectively adopted in a kind of above-mentioned compressor movement flexible support structure, the upper bushing and lower bushing
At.
The utility model is as a result of above-mentioned technical pattern, the corrugated tube shape among high damping material combination elastic element
Design, keeps the axial rigidity of entire elastic element smaller than spring（The metal elastic that rigidity can certainly be used smaller
Spring can equally reduce the coupling stiffness between movement and shell）.Although compressor start moment movement will produce larger water
Square to displacement, but since there are the overlapping regions of certain altitude with lower bushing top for upper bushing lower part, to limit movement
Larger horizontal direction displacement amplitude is will produce, movement is avoided to hit shell.Simultaneously as plastics are respectively adopted in upper bushing and lower bushing
Material is made, and the two mutually collides and not will produce abnormal sound.Compressor can both be reduced using the utility model flexible support structure
Coupling stiffness between movement and shell, to achieve the effect that reduce vibration of compressor, and can be to avoid compressor start when
Hit shell problem.

Specific implementation mode
As depicted in figs. 1 and 2, the utility model compressor movement flexible support structure 1 is set in compressor housing 8.Please
Shown in Fig. 3, stator 9 is fixed on crankcase 10 by compressor movement support construction 1 by screw 2.It is first when installation
Gasket 3 is first put on screw 2, and stator 9 is fixed on crankcase 10.After installation, then upper bushing 5 is pressed on screw 2,
Entire movement installs.
As shown in figure 3, the utility model compressor movement flexible support structure 1 includes gasket 3, elastic element 4, upper bushing
5, lower bushing 6 and stud 7.Elastic element 4 is made of high damping material, such as high-damping rubber.The middle area of elastic element 4
Corrugated tube shape is presented in domain, and the variation of volume occurs in order to the internal cavity of elastic element 4.The intermediate region of elastic element 4
Top is provided with gas vent, in order to which the gas outside the gas and cavity in 4 cavity of elastic element moves, to which consumption is shaken
Energy.The smallest cross-sectional size of gas vent is d2.Plastic material may be used in the making material of upper bushing 5 and lower bushing 6, such as
PBT, the two mutually collide and not will produce abnormal sound.The lower edge outer ring largest cross-sectional sized d3 of upper bushing 5 is less than lower bushing 6
