Abstract
The utility model relates to a refrigerating screw compressor rotor which comprises a female rotor with two asymmetrical sides and a male rotor, wherein a composition curve for the female rotor and the male rotor comprises a circular arc and an envelope thereof, the number of teeth ratio of the female rotor and the male rotor is 6:5, and a clearance is formed between the female rotor and the male rotor; and the refrigerating screw compressor rotor is characterized in that the center point of the female rotor is taken as the origin of coordinate, the clearance between the female rotor and the male rotor is 0.02-0.06 mm, and the rotor manufactured according to the actual profile coordinate has the characteristics of convex-convex, large rotor and low rotational speed. Compared with the prior art, the utility model can fully achieves the purpose of convex-convex sealing, thereby being helpful to form a hydrodynamic lubricating film, the lateral leakage during passing through the contact strip is reduced and the efficiency of the compressor is improved; and the processing and the inspection performances of the rotor are improved, and due to the adoption of the design thinking of large rotor and low rotational speed, the noise and the vibration can be reduced, the rigidity of the rotor is enhanced, the service life is prolonged, and the sensitivity to the machining precision, the foreign impurities and the oil carbide is relatively reduced.
Description
Technical field
The utility model relates to a kind of rotor, relates in particular to a kind of refrigerant 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 refrigerant rotor of helical lobe compressor, and 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, reduce transverse leakage, improve compressor efficiency by 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 6: 5, 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:
Male rotor
Female rotor
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 refrigerant 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:
