SCREW COMPRESSOR GEARING |
摘要 |
FIELD: compressor technology. SUBSTANCE: gearing is formed by two parallel to rotors with interrounded screw surfaces and large and small numbers of starts each in end face section having tooth profile asymmetric to straight line running through tooth point and rotor rotation center. Tooth profile of rotor screw part with small number of starts on side of lower pressure from addendum circle to pitch circle is formed by successively located connected curves. Sections of profile of rotor screw part with large number of starts are rounding the respective rotor sections with small number of starts. EFFECT: higher efficiency of gearing due to increased length of gas throttling path over tooth point and increased pressure angle on profile from low pressure side. 3 dwg
