Abstract:

In the study of general scroll profiles and its conjugation profiles for scroll compressor, the general scroll profiles equation based on functional analysis was given using the intrinsic equation of curvature radius and curve differential coefficient. The scroll profiles pitch line and controll equation were researched.The conjugation scroll profiles of orbiting and fixed scroll discs were deduced through scroll profile controll equation. The conclusion is that the scroll profile controll equation is the necessary condition to create the scroll profiles for the scroll compressor,not the sufficient condition. While the profiles are just the scroll profiles for scroll compressor, the controll equation can create the conjugation scroll profiles of the orbiting and fixed scroll discs. On the contrary, only knowing scroll profile controll equation,but the profiles do not belong to the scroll profiles for scroll compressor, the scroll profile controll equation can not create the scroll profiles for scroll compressor.
