Abstract
A kind of small compressor balance block of windage disclosed in the utility model, includes the main body in semi-annular shape, and the main body both sides are equipped with mounting hole close to the position on bottom edge, and the main body both sides bottom edge is arc transition；The main body front stage casing is equipped with exacerbation portion, it is overlapped with main body outer circle on the outside of the exacerbation portion, it is the Double-ladder structure containing side in inside top margin and inside on the inside of exacerbation portion, joint face in the inside top margin and inside between side is perpendicular, and the joint face in inside between side and the internal circle of main body is clinoplain；The exacerbation portion both sides bottom edge is bevel edge, and the angle between bevel edge and horizontal line is 20 °.The trapezoidal end faces of balance weight can reduce rotor and run at high speed disturbance of the balance weight raised face to air-flow at present, overcome the big defect of conventional balanced block structure flow resistance, reduce the windage effect that balance weight rotation generates, compressor power consumption is reduced, the heat exchange efficiency of electric system and the reliability of compressor operating are improved.
Description
Technical field
The utility model is related to balance weight fields, more particularly to a kind of compressor balance block that windage is small.
Background technology
Balance weight can offset compressor crank shaft and make to the radial direction of motor output shaft in the rotation process of compressor crank shaft
Firmly, and then the radial load that makes motor output shaft be subject in rotation process reaches equilibrium state, and ensure that motor stablizes fortune
Row.Traditional balance weight can form very big windage when rotating, and cause the power consumption of compressor to increase, and rotating speed is higher, power consumption is bigger.
Invention content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of compressor balance block that windage is small,
It solves the problems, such as that conventional balanced block structure flow resistance is big, reduces compressor power consumption, improve heat exchange efficiency and the compression of electric system
Machine reliability of operation.
Technical solution used by the utility model is：A kind of compressor balance block that windage is small, including be in semi-annular shape
Main body, the main body both sides close to bottom edge position be equipped with mounting hole, the main body both sides bottom edge be arc transition；Institute
The main body front stage casing stated is equipped with exacerbation portion, is overlapped with main body outer circle on the outside of the exacerbation portion, for containing interior on the inside of exacerbation portion
The Double-ladder structure on side in side top margin and inside, the joint face in the inside top margin and inside between side are vertical flat
Face, the joint face in inside between side and the internal circle of main body are clinoplain；The exacerbation portion both sides bottom edge is bevel edge, tiltedly
Angle between side and horizontal line is 20 °.
Further, the body thickness is 10mm, and the thickness in the exacerbation portion is 9.8mm.
Further, on the mounting hole it is below 45 ° of chamfereds, the length of side of upper chamfering is 0.5mm, lower chamfering
The length of side is 0.8mm.
In conclusion the compressor balance block that a kind of windage of the utility model is small, trapezoidal end faces can reduce motor
Rotor runs at high speed disturbance of the balance weight raised face to air-flow at present, overcomes the big defect of conventional balanced block structure flow resistance, subtracts
The windage effect that small balance weight rotation generates, reduces compressor power consumption, improves the heat exchange efficiency and compressor fortune of electric system
Capable reliability.

Specific implementation mode
Embodiment 1
The utility model is as shown in Figure 1 and Figure 2, and a kind of compressor balance block that windage is small, includes the main body in semi-annular shape
1, the main body both sides are equipped with mounting hole 2 close to the position on bottom edge, and the main body both sides bottom edge is 3 transition of circular arc；It is described
Main body front stage casing be equipped with exacerbation portion 4, is overlapped with main body outer circle 5 on the outside of the exacerbation portion, exacerbation portion inside is containing interior
The Double-ladder structure on side 8 in side top margin 7 and inside, the joint face in the inside top margin and inside between side are vertical flat
Face, the joint face in inside between side and the internal circle 6 of main body are clinoplain；The exacerbation portion both sides bottom edge is bevel edge 9,
Angle between bevel edge and horizontal line is 20 °.
In the present embodiment, the body thickness is 10mm, and the thickness in the exacerbation portion is 9.8mm.
In the present embodiment, on the mounting hole it is below 45 ° of chamfereds, the length of side of upper chamfering is 0.5mm, is fallen down
The length of side at angle is 0.8mm.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not
Be confined to this, any one skilled in the art within the technical scope disclosed by the utility model, according to this practicality
Novel technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
