摘要：
A new type of variable thickness scroll compressor line composed of circular involutes with different base circle radii is proposed, which is composed of a circular involute I+ circular involute II+ circular involute I. The method of generating the profile is discussed, the general equations of the profile are given, and a series of geometric models of the circular involute variable thickness scroll compressor are established. Aiming at the established geometric model, the influence of the control coefficientsθ, φ* and Ror on the geometric performance of the variable thickness scroll compressor is analyzed. Based on the circular involute Ⅰ, a geometric model of variable thickness scroll compressors with circular involute Ⅰ + higher-order curve + circular involute Ⅰ is constructed, and the geometric performance of two types of variable thickness scroll compressors is comprehensively analyzed. The results show that: θ taking the median value θM,φ* taking the value of φend-2(n1+1) π, and Ror taking the larger, the corresponding geometric performance is better. Higher-order curve variable thickness scroll compressors are similar to the circular involute variable thickness scroll compressors corresponding to the median valueθM, and can be substituted for each other. © 2020 Journal of Mechanical Engineering.
