titleOfInvention A kind of double-screw compressor rotor flute profile
abstract The utility model discloses a kind of double-screw compressor rotor flute profile, the flute profile line of female rotor and the flute profile line of male rotor are smoothly connected by multistage conic section head and the tail to be formed, conic section include circular arc, pin tooth circular arc and arc envelope line, female rotor and each tooth of male rotor multistage tooth curve composition it is as follows, wherein:Seven sections of secondary tooth curves of each tooth of female rotor include what order was smoothly connected:Circular arc A 2 B 2 , circular arc B 2 C 2 , arc envelope line C 2 D 2 , parabolic envelope D 2 E 2 , pin tooth circular arc E 2 F 2 , arc envelope line F 2 G 2 , circular arc G 2 H 2 ;The curve of male rotor include order and be smoothly connected:Arc envelope line A 1 B 1 , arc envelope line B 1 C 1 , pin tooth circular arc C 1 D 1 , circular arc D 1 E 1 , arc envelope line E 1 F 1 , circular arc F 1 G 1 .The utility model leakage triangle is smaller, reduces the disturbance resistance of air-flow, reduces noise, is easy to process using gear hobbing, the length of contact line is relatively short, largely reduces the leakage of compressor, and relative efficiency is higher.
