Research on the Influence of Gear Shift and Modification on the Tooth Contact Temperature

Yu Dongyang;Zhang Chao;Ye Shengjian;Li Wei;Fu Wenbin;Yu Fangdi;No.703 Research Institute of CSIC;School of Mechanical Engineering,University of Science and Technology Beijing;  
The calculation method of tooth surface temperature is studied,based on the model of thermal shock and Hertz contact theory,the calculation formula of instantaneous contact temperature on tooth surface is derived,the calculation problem of gear body temperature and the flash temperature are discussed,the influence of gear shift coefficient and modification parameters on transient contact temperature of gear tooth is analyzed,the change rule of the flash temperature along the meshing line is revealed,the research results show that the proper choice of gear shift coefficient and modification parameters can significantly improve the resistance scuffing performance of gear transmission system,avoid scuffing failure.
