摘要：
The scroll profile of variable base circles with internal and external starting angles was studied. Based on whether the opening angle started on x axis, the external and internal profile equations of two types of variable base circles were given. The expression of eccentric distance was deduced and the relation between two types of base circles with changing radius profile equations was analyzed. The scroll profile of variable base circles was modified in double arc and the modified profile equations of double arc were given. The relation between two types of modified profile equations was analyzed and the influences of the modified opening angles on the modified tooth profile and compression ratio were explored, which may provide a reference for further studies on variable base circle scroll profiles. © 2019, Editorial Department of Journal of Northeastern University.
