Abstract

The utility model relates to a rotor of a screw compressor, which comprises a female rotor with dissymmetrical double edges and a male rotor; the composite curve of the female rotor and the male rotor is a circular arc, the gear ratio of the curve to an envelope curve is 5: 4, and an interstice is formed between the female rotor and the male rotor. The utility model is characterized in that the center point of the female rotor is used as the origin of coordinates, and the interstice between the female rotor and the male rotor is from 0.02 to 0.06mm; the rotor manufactured by actual profile coordinates has the characteristics of curve face to curve face, big rotor and low rotating speed. Compared with the prior art, the utility model realizes the sealing of a curve face to a curve face so as to be helpful to forming hydrodynamic lubrication membrane, reducing transversal leakage through a contact zone, enhancing the efficiency of the compressor, and improving the processing property and the checking property of the rotor; the rotor of a screw compressor adopts the design clew of a big rotor and low rotating speed so as to decrease noise and vibration, enhance the rigidity of the rotor, extend the service life, improve machining accuracy and relatively decrease the sensitivity to impurities and oil carbide.

Description

A kind of rotor of helical lobe compressor
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 substantially, existing in the world at present representational molded lines of rotor mainly contains: the molded lines of certain company of Germany, the molded lines of Sweden company, and the molded lines of company such as Taiwan, Japan, these molded lines are chosen different curves and combination thereof, because the design orientation is different, and should each have their own pluses and minuses.But the common drawback that prior art exists is: the less rotating speed height that causes of root diameter can occur noise in actual applications, vibration is big, rigidity is not enough, thereby influence working life.
Summary of the invention
The purpose of this utility model is to provide a kind of novel rotor of helical lobe compressor, its design orientation is: realize the sealing of " curved surface is to curved surface " between rotor fully, and do not comprise the sealing of any " curve-curve ", help to form the hydrodynamic lubrication film, reduction improves compressor efficiency by the transverse leakage of contact zones; Improve the processibility of rotor, be convenient to adopt filing processing, also easier check; Greater trochanter, the slow-speed of revolution to reduce noise and vibration, improve the rotor rigidity, increase the service life.Receptance to machining accuracy, impurity and oily carbide is little.
For overcoming the above-mentioned deficiency of prior art, the utility model has adopted following technological scheme, this rotor of helical lobe compressor comprises female rotor, male rotor, female rotor and male rotor bilateral asymmetric, forming curve is circular arc and envelope thereof, the gear ratio of negative and positive rotor is 5: 4, has the gap between the negative and positive rotor, it is characterized in that: the central point with female rotor is a true origin, the negative and positive gap between rotor is 0.02-0.06mm, and its actual profile coordinate is as follows:

During concrete enforcement, the negative and positive gap between rotor is 0.05mm.
The utility model compared with the prior art, owing to adopted this molded lines to make the sealing that has realized " curved surface is to curved surface " between rotor fully, and do not comprised the sealing of any " curve-curve ", helped to form the hydrodynamic lubrication film, reduction improves compressor efficiency by the transverse leakage of contact zones.Owing to adopted circular arc or arc envelope line fully, thereby improved the processibility of rotor, be convenient to adopt filing processing, also easier check.After adopting greater trochanter, slow-speed of revolution mentality of designing, can reduce noise and vibration, improve the rotor rigidity, increase the service life, also reduce the receptance of machining accuracy, impurity and oily carbide is relative.
Description of drawings
Accompanying drawing is the utility model negative and positive rotor end surface shape schematic representation in rectangular coordinate system.
Embodiment
Below in conjunction with accompanying drawing specific embodiments of the present utility model is elaborated:
Embodiment: a kind of rotor of helical lobe compressor (referring to figure), it comprises female rotor 1, male rotor 2, female rotor 1 and male rotor 2 bilateral asymmetric, form curve and be circular arc or arc envelope line, the number of teeth of female rotor is 5, and the number of teeth of male rotor is 4, and the negative and positive gap between rotor is 0.05mm, consider the machining error problem, the gap can be relaxed to 0.02-0.06mm.
Central point with female rotor 1 is a true origin, and the gapped actual profile coordinate of female rotor 1, male rotor 2 is as follows:
