Abstract

The utility model discloses a screw compressor rotor, comprising a female rotor (1) and a male rotor (2), which is characterized in that the doubling piece of the female rotor (1) and the male rotor (2) is asymmetry, the constitutive curve is a circular arc and the envelop curve of the circular arc, the gear ratio of the female rotor and the male rotor is 5:4. The utility model has the advantages that the utility model has a smooth mesh and reduces the wear and tear, has good tightness and is easy to be processed and detected, the vibration is small and the noise is low, so that the efficiency of the compressor is increased.

Description

A kind of rotor of helical lobe compressor
One, technical field: the utility model relates to a kind of rotor, relates in particular to a kind of rotor of helical lobe compressor.
Two, background technique: in the helical-lobe compressor, the shape of rotor has determined the performance of helical-lobe compressor substantially, the shape line of present existing rotor of helical lobe compressor is monolateral asymmetric cycloid-pin tooth circular arc line, because the distance of the Line of contact summit of negative and positive rotor and rotor tooth tip circle intersection point increases, axially tightness reduces, and efficient is low, there is cusp in the tooth root of male rotor, formation stress is concentrated, and is unfavorable for bearing big load, and is not easy to processing and detection.
Three, technology contents: the not enough face that the purpose of this utility model is to overcome above-mentioned existing technology provides a kind of engagement steady, reduces wear, and good airproof performance is convenient to processing and is detected, and vibrate for a short time, and noise is low, the rotor of helical lobe compressor of raising compressor efficiency.
The purpose of this utility model can reach by following measure: a kind of rotor of helical lobe compressor, he comprises female rotor 1, male rotor 2, it is characterized in that the bilateral asymmetric of female rotor 1 and male rotor 2, forming curve is circular arc and envelope thereof, and the gear ratio of negative and positive rotor is 5: 4.
The utility model can produce following good effect compared with the prior art:
1. the utility model composition tooth curve is circular arc, ellipse and envelope thereof, this makes the rotor flank of tooth change face seal into by linear sealing, can obviously improve sealing effect, help forming the hydrodynamic lubrication oil film and reduce tooth surface abrasion, Line of contact is short, engagement is steadily lowered the horizontal leakage by Line of contact, improves compressor efficiency.
2. smooth connection between the bent flank of tooth of the utility model does not have cusp on the molded lines, is convenient to processing and detection, and cleanliness is good, and noise is low.
3. adopt bilateral molded lines, root diameter is easy to adjust, and moment is distributed rationally between rotor, vibrates little.
4. rotor tooth depth radius and addendum are reasonable, and area utilization factor is big, and displacement and refrigerating capacity improve.
5. the negative and positive root diameter is more or less the same, and rotor rigidity is approaching, and the bearing capacity height has less thermal distortion and bending deflection, can be used for the bigger operating mode of pressure reduction and pressure ratio.
Four, description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Five, embodiment: embodiment of the present utility model is elaborated below in conjunction with accompanying drawing:
Embodiment: a kind of rotor of helical lobe compressor (referring to figure), it comprises the bilateral asymmetric of female rotor 1, male rotor 2, female rotor 1 and male rotor 2, form curve and be circular arc, ellipse and envelope thereof, the number of teeth of female rotor is 5, the number of teeth of male rotor is 4, the negative and positive gap between rotor is 0.07mm, the gapped actual profile coordinate of female rotor 1, male rotor 2 following (central point with female rotor is a coordinate points):
