Paper Abstract

Profiles type selection is very important for scroll compressor. Inherent engagement mechanism was discovered in the study of scrolls. And a novel method for scroll profiles based on inherent engagement mechanism is proposed. The result shows that the engagement region angle (ERA) of odd regular polygon involutes is half of the characteristic-geometry exterior angle, and that of even regular polygon involutes is equal to the exterior angle to the moment. The corresponding ERA is reducing increasingly with the edge number increasing of characteristic geometry. The performance characteristics of scroll compressor tend towards the best correspondingly. Aiming at existed problems of profile design for scrolls, it developed a novel methodology to study scroll profile. Originality research was done for the further study of scroll profile. It is the fundamentality factor representing essence character of scroll profiles function itself.
