Calculation of Stress Concentration Factor Ys for External Gears
Wei Liren Department of Basic Courses
The reference  is mainly studied and the references , ,  are also re- ferred in this paper. The reasons concerning how to convert the nominal bending stress into teeth root partial stress, how to analyze various auxiliary values of Ys. how to set up specific mathematical model and how to pre- pare calculation program flowchart are all examined by the author. Making use of some tested data of correction factor X and teeth number Z, the program is successfully operated on an APPLE-i I computer and the ideal results of Ys are obtained.
