Abstract
The utility model discloses a screw compressor rotor. The screw compressor rotor comprises a male rotor and a female rotor. The screw compressor rotor is characterized in that double sides of the male rotor and the female rotor are asymmetrical, constitute curves of the male rotor and the female rotor are circular arc or circular arc envelope lines, the gear ratio of the male rotor and the female rotor is 4:5, and the gap between the male rotor and the female rotor is in a range from 0.08mm to 0.12mm. By means of the screw compressor rotor, problems in prior art can be effectively solved, the rotate speed is high, the noise is low, the service life is long, the compressor efficiency can be improved, and the detection is convenient.
Description
Technical field
The utility model relates to a kind of rotor, relates in particular to a kind of rotor of helical lobe compressor.
Background technique
In the helical-lobe compressor, the shape of rotor has determined the performance of helical-lobe compressor basically, and existing representational molded lines of rotor mainly is distributed in Germany, Sweden, Japan and Taiwan in the world at present.These representational molded lines of rotor are different because of Orientation of design, choose different curves and combination thereof, cut both ways.From in general, the common shortcoming that prior art exists is: root diameter is little, and linear velocity is higher, and gear ratio is more.The noise height can occur in actual applications, vibration is large, and special rotor tooth form is thiner, and rigidity is not enough, thereby has influence on work efficiency, compression efficiency, working life etc. one the row problem.The problems referred to above need to be solved by technological innovation.
The model utility content
The utility model technical issues that need to address provide a kind of enhancing rigidity, reduce linear speed, the rotor of helical lobe compressor that gear is little and noise is low.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of rotor of helical lobe compressor, comprise male rotor and female rotor, it is characterized in that: male rotor and female rotor bilateral asymmetric, its constituent curve is circular arc or arc envelope line, the gear ratio of positive and negative rotor is 4: 5, gap between male rotor and the female rotor is 0.08~0.12mm, and take the center of male rotor as initial point, the coordinate of male rotor, the gapped actual molded line of female rotor is as follows:
Compared with prior art, the utility model has following advantage:
One, the transfer of torque mode adopts the involute way of contact that is similar to gear between the yin, yang rotor, is the way of contact of line and line, compares with the way of contact of point with the point that existing a lot of designs are adopted, and has improved the reliability that moment of torsion transmits between the rotor.
Two, rotor is realized the sealing of " curved surface is to curved surface " fully, in whole contact process, remain good sealing between rotor, and the leakage triangle area is less, the relative movement of rotor contact surface produce friction minimum, help to form the hydrodynamic lubrication film, reduce the transverse leakage by contact zones, improve the compression efficiency of compressor.
Three, adopt male rotor and 4: 5 ratio of the female rotor number of teeth, improved the processibility of rotor, be convenient to adopt filing processing, improve work efficiency and correcting efficiency.
Four, air-breathing area is large, and it is little to the conjugation power of base pressure survey that rotor overcomes the high pressure side, and the moment of torsion of transmission is smaller, and the air displacement of compressor is larger.
Five, the more abundant powerful female rotor of female rotor profile of tooth, rotor is more steady at the volley, reduced because of rotor deformation produce kill may.
Description of drawings
Fig. 1 is the utility model embodiment's structural representation.
Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
In conjunction with Fig. 1, the utility model relates to a kind of rotor of helical lobe compressor, comprise: male rotor 1 and female rotor 2, wherein, male rotor 1 and female rotor 2 are bilateral asymmetric, its constituent curve is circular arc or arc envelope line, the number of teeth of male rotor 1 is 4, and the number of teeth of female rotor 2 is 5, and the gap between male rotor 1 and the female rotor 2 is 0.10mm, take the center of male rotor 1 as initial point, the coordinate of male rotor 1 and female rotor 2 is:
The utility model can effectively solve the problem of prior art, rotating speed height and noise is low, and the life-span is long, can improve compressor efficiency and be convenient to and detect.
