Investigation Of Multiply Spirals Profile For Scroll Compressor

摘要

The multiply spirals performances such as displacement, pressure ratio, fiction velocity, wrap radius and leakage wire length, etc. of circle involute profile with different spirals are investigated and compared. In order to extend the range of meshing profile of multiply spirals, the regular polygon involute is proposed besides the circle involute. The involute of regular polygon with 2iZ(i =1,2,3, …) sides can be used as multiply spirals profile of Z spirals. For example, the 4,8,12, … regular polygon involute can be used as 2-spirals profile; and the 6,12,18, … regular polygon involute can be used as 3-spirals profile. What's more, other meshing profiles of polygon involute for multiply spirals are also obtained.
