Description

A kind of rotor combination of 75-150 horsepower double-screw air compressor
Technical field
The utility model relates to a kind of Air Compressor compression assembly.
Background technique
Double-screw air compressor utilizes female rotor, the male rotor of conjugation engagement running in the cavity to export pressurized air continuously.The characteristics of female rotor, male rotor end face molded lines have determined the performance and the efficient of compressor.The manufacturer of double-screw air compressor all is devoted to the molded lines research of yin, yang rotor flute profile now; It is ZL 200820056997.2 that for example Chinese utility model patent specification CN201180654Y discloses the patent No.; Name is called the technological scheme of " double-screw air compressor screw rotor ", proposes this screw rotor and comprises a pair of intermeshing female rotor and male rotor; Wherein: female rotor is established 6 teeth, and its end face molded lines is made up of three circular arc lines, arc envelope line, straight line (junction of this arc envelope line and this straight line is an isolated point), a cycloid and two circular arc lines to the top circle of next tooth from the top circle of a tooth in order; Male rotor is established 4 teeth, and its end face molded lines is made up of two arc envelope lines, two circular arc lines, two cycloids, a circular arc line (junction of a back cycloid and this circular arc line is an isolated point) and circular arc lines to the root circle of next tooth from the root circle of a tooth in order.The document discloses the coordinate analytic value of forming each section of female rotor profile of tooth curved section and the coordinate analytic value of forming each section of male rotor profile of tooth curved section.The disclosed technological scheme of the document has can reduce fluid dynamic loss and reduction noise, and the leakage triangle area is little.Laterally reveal advantages such as little; But its female rotor and male rotor molded lines contain isolated point, even straight line, are difficult for processing.
The model utility content
The utility model aims to provide the rotor combination that a kind of female rotor and male rotor molded lines do not contain isolated point and straight line, are prone to the 75-150 horsepower double-screw air compressor of processing.
The technological scheme of the utility model is: a kind of rotor combination of 75-150 horsepower double-screw air compressor, a pair of intermeshing female rotor and male rotor are arranged, and female rotor is established 6 left-handed teeth, and male rotor is established the tooth of 5 dextrorotation; The coordinate analytic value of forming each section of female rotor profile of tooth curved section is:

Each tooth is provided with tooth top circular arc ab, connection circular arc bc, arc envelope line cd, arc envelope line de, arc envelope line ef, pendulum point protection circular arc fg on the said female rotor; On the said male rotor each tooth be provided with respectively with above-mentioned female rotor on the corresponding circular arc of each circular arc of each tooth: tooth root circular arc AB, arc envelope line BC, transition arc CD, tooth top circular arc DE, pendulum point protection circular arc EF, arc envelope line FG.
It is 5 that the male rotor number of teeth is adopted in the combination of the rotor of the utility model 75=150 horsepower double-screw air compressor, and the female rotor number of teeth is that 6 number of teeth combination can make the pressure reduction between element volume reduce, and the suction and discharge orifice area increases and helps improving compressor efficiency.The molded lines structure that adopts the coordinate figure of above-mentioned yin, yang rotor to form, the sealability between the yin, yang rotor tooth, between the volume stops pressurized gas to leak to low voltage terminal by the sealing strip of three broads; And selected less leakage triangle for use; All the tooth curve is formed by circular arc and arc envelope line, and each tooth curve has been stopped isolated point, straight line; Improve the rotor processibility, be convenient to adopt gear hobbing, mill, grind processing processing.The rotor combination of the utility model 75-150 horsepower double-screw air compressor; Adopt above-mentioned molded lines to form; Not a linear sealing in the above-mentioned molded lines engagement process but realize the flank of tooth multi-sealed to the flank of tooth in several zones fully; Help and form the hydrodynamic lubrication oil film, reduce transverse leakage through Line of contact.Above-mentioned molded lines adopts less circular arc excessive, and leakage triangle is little, leaks few.Adopt the tooth top circular arc both to protect potted line to form point, be convenient to measure the male rotor external diameter again.Adopt the male rotor tooth top three-arc to connect, female rotor do not adopt circular arc take all of arc way and to the tooth top three-arc entirely with the arc envelope line engagement, the pump-absorb action of having avoided tooth curve moment engagement moment to throw off is of value to and forms oil film and reduce noise.It is streamlined that the moon, all tie points of male rotor molded lines all are that rounding off is, and resistance of air is little, reduced the fluid dynamic loss and reduced noise.All cycloids form point all has the circular arc protection, therefore has better comprehensive performance.
Description of drawings
Fig. 1 is a rotor set unification embodiment's of the utility model 75-150 horsepower double-screw air compressor an end-face structure schematic representation.
Fig. 2 is the local enlarged diagram of T portion among Fig. 1.
Embodiment
A rotor set unification embodiment's of the utility model 75-150 horsepower double-screw air compressor end-face structure, as shown in Figure 1, this rotor set is combined into a pair of intermeshing female rotor 1 and male rotor 2, and the end-face structure of this rotor combination is as shown in Figure 1.Female rotor 1 is established 6 left-handed teeth, and male rotor 2 is established the tooth of 5 dextrorotation.On the female rotor 1 on the helix angle numerical value of each tooth and the male rotor 2 the helix angle numerical value of each tooth be 46.04 °; On the female rotor 1 on the length of toothed region and the male rotor 2 length of toothed region be 269 millimeters; The tooth depth of male rotor 2 is 32.23 millimeters, and the tooth depth of female rotor 1 is 32.23 millimeters.The external diameter of female rotor 1 is 131.832 millimeters, and the external diameter of male rotor 2 is 166.966 millimeters.
The coordinate analytic value of forming female rotor 1 each section of profile of tooth curved section is:

The molded lines structure that adopts the coordinate figure of above-mentioned female rotor 1, male rotor 2 to form, as shown in Figure 2: on the female rotor 1 each tooth be provided with tooth top circular arc ab, connect circular arc bc, arc envelope line cd, arc envelope line de, arc envelope line ef, pendulum point protection circular arc fg.On the male rotor 2 each tooth be provided with respectively with above-mentioned female rotor 1 on the corresponding circular arc of each circular arc of each tooth, tooth root circular arc AB, arc envelope line BC, transition arc CD, tooth top circular arc DE, pendulum point protection circular arc EF, arc envelope line FG.
Sealability between female rotor 1 and male rotor 2 between cog, the volume; Sealing strip by three broads stops pressurized gas to leak to low voltage terminal; And selected less leakage triangle for use, and all the tooth curve is formed by circular arc and arc envelope line, and each tooth curve has been stopped isolated point and straight line.Not a linear sealing in the above-mentioned molded lines engagement process but realize the flank of tooth multi-sealed to the flank of tooth in several zones fully that adopt less circular arc excessive, leakage triangle is little, leaks few.Male rotor 2 tooth top three-arcs connect, and female rotor 1 tooth top three-arc meshes with arc envelope line entirely.It is streamlined that all tie points of molded lines of female rotor 1 and male rotor 2 all are that rounding off is, and all cycloids form point all has the circular arc protection.
The above is merely the utility model preferred embodiment, does not limit the scope that the utility model is implemented with this, and the equivalence of doing according to the technological scheme and the description of the utility model changes and modification, all should belong to the scope that the utility model is contained.
