Abstract
Based on the mechanism analysis of comer contact,the method for the system model of gear error-deformation calcula- tion is established on the line of action.According to the distributive law of key transmission errors,the effective system error is obtained along the line.The synthetic tooth compliance of the point lying in comer contact is inversed based on the theory of en- gagement and the curve of tooth synthetic compliance load-history.Combined the effective error for gear system with complex deflection of engaging teeth,the standard of the point situated at comer contact is probed.The key data of the position and impact force from the beginning point of comer contact obtained,and the impact velocity and forces,from the beginning to the end position situated at comer contact,are calculated accurately.Due to the key data,the lash model during comer contact is founded,and the impact friction force and coefficient of engaging points are calculated.Compared with the relative studies,the above model,calc u- lating method and analytical conclusions are reliable.The results could be referenced to study frictional performance of tooth profile and damp and denoise.
