Abstract
A kind of compressor balance block for high-speed electric expreess locomotive disclosed in the utility model, the balance weight are in semi-annular shape, are arc transition between balance weight outer circumferential edge and internal circle, mounting hole is equipped at left and right sides of balance weight；The positive Middle face of the balance weight is equipped with the circle convex platform overlapped respectively with internal circle with the outer circumferential edge of balance weight, the circle convex platform and balance weight integral forming, the circle convex platform both sides tail end is interior bevel edge transition, and the angle between the interior bevel edge and horizontal line is 14 °.The mounting hole lower edges are chamfered, and the aperture of the mounting hole is 9.6mm.The thickness of the balance weight is 8mm, and the width of the balance weight is 16.1mm.The bevel edge design of circle convex platform solves the problems, such as that conventional balanced block structure flow resistance is big, reduces compressor power consumption, electric system can be allowed to be maintained under high velocity environment and run.
Description
Technical field
The utility model is related to balance weight fields, more particularly to a kind of compressor balance block for high-speed electric expreess locomotive.
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, it is flat to provide a kind of compressor for high-speed electric expreess locomotive for the utility model
Weigh block, solves the problems, such as that conventional balanced block structure flow resistance is big by the bevel edge design of circle convex platform, reduces compressor power consumption, can allow
Electric system is maintained under high velocity environment and runs.
Technical solution used by the utility model is：A kind of compressor balance block for high-speed electric expreess locomotive, described is flat
The block that weighs is in semi-annular shape, is arc transition between balance weight outer circumferential edge and internal circle, mounting hole is equipped at left and right sides of balance weight；Institute
The positive Middle face of balance weight stated is equipped with the circle convex platform overlapped respectively with internal circle with the outer circumferential edge of balance weight, and the annulus is convex
Platform and balance weight integral forming, the circle convex platform both sides tail end are interior bevel edge transition, the interior bevel edge and horizontal line
Between angle be 14 °.
Further, the mounting hole lower edges are chamfered, and the aperture of the mounting hole is 9.6mm.
Further, the thickness of the balance weight is 8mm, and the width of the balance weight is 16.1mm.
In conclusion a kind of compressor balance block for high-speed electric expreess locomotive of the utility model, overcomes conventional balanced block
The big defect of structure flow resistance reduces the windage effect that balance weight rotation generates, reduces compressor power consumption, improve electric system
The reliability of heat exchange efficiency and compressor operating.

Specific implementation mode
Embodiment 1
The utility model is as shown in Figure 1-Figure 3, a kind of compressor balance block for high-speed electric expreess locomotive, the balance weight 1
It is 4 transition of circular arc in semi-annular shape, between balance weight outer circumferential edge 2 and internal circle 3, mounting hole 5 is equipped at left and right sides of balance weight；Institute
The positive Middle face of balance weight stated is equipped with the circle convex platform 6 overlapped respectively with internal circle with the outer circumferential edge of balance weight, the annulus
Boss and balance weight integral forming, the circle convex platform both sides tail end are 7 transition of interior bevel edge, the interior bevel edge and level
Angle between line is 14 °.
In the present embodiment, as shown in Fig. 2, the mounting hole lower edges are chamfered, the mounting hole
Aperture is 9.6mm.
In the present embodiment, the thickness of the balance weight is 8mm, and the width of the balance weight is 16.1mm.
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.
