Abstract: A
new method named nomal-equidistant-curve method is presented to generate
profile for scroll compressor. Theorem for generating profile is
demonstrated. General equation describing geometry of scroll is given.
The relationship between type of generatrix and profile of scroll is
discussed in detail. Advantages of nomal-equidistant-curve method versus
traditional generating method are summarized. The basic requirements
that generatrix of profiles should meet are explicated. A set of
formulas for calculating volume of symmetric compression chamber and gas
forces in it is offered. The nomal-equidistant-curve method and above
formulas could be applied in scroll compressor design and its
performance optimization.
