热弹耦合条件下的齿廓修形设计
Tooth profile modification under thermoelastic coupling
摘要
Abstract
To study the influence of thermal deformation on the characteristics of gear transmission, this work de-duced the thermal deformation calculation formula of any point in the involute profile along the meshing line. On the basis of the formula,the influences of thermal deformation on the intertooth load-sharing ratio,transmission er-ror,and tooth profile modification were studied. Piecewise modification and continuous modification were proposed under thermoelastic coupling,and an expression on the modification amount in the two methods was obtained. The load-sharing ratio and the transmission error of the modification system in two different ways were also analyzed. Results show that piecewise modification could properly maintain the continuity of the load-sharing ratio in the mes-hing process,extinguish load mutation,reduce the fluctuation of the transmission error, and stabilize the absolute error. In continuous modification,the load-sharing ratio was continuous,the load mutation disappeared,the single-tooth meshing area increased slightly, and the fluctuation of the transmission error was slightly larger than that of piecewise modification. This research could effectively reduce vibration and noise in the process of gear transmis-sion and demonstrated application value.关键词
