圆弧齿线圆柱齿轮接触动力学特性分析

Analysis of the Contact Dynamics Characteristic of Cylindrical Gear with Arcuate Tooth Trace

基于UG建立了不同齿宽的圆弧齿线圆柱齿轮副的三维模型;借助ADAMS对齿轮副进行运动学、动力学比较分析,得出轮齿转速、啮合力在不同齿宽下的变化规律。通过对圆弧齿线圆柱齿轮进行运动学分析,验证了该齿轮传动的平稳性,且当1.3r_0<b<1.9r_0时,轮齿转速的误差最小;通过对圆弧齿线圆柱齿轮进行动力学分析,得出当1.2r_0<b<1.8r_0时,齿轮副传动平稳性最好,承载能力最强,性能最优。该分析方法为圆弧齿线圆柱齿轮在高速重载工作条件下的设计提供了理论依据,具有工程应用价值。

Based the UG,the three- dimensional models of different tooth width of cylindrical gears with arcuate tooth trace are established.The change rule of rotational speed and meshing forces are obtained through comparing and analyzing the kinematics and dynamics of different tooth width by help of ADAMS.By the kinematics analysis,the running steadiness of cylindrical gear with arcuate tooth trace is verified.When 1.3r0〈b〈1.9r0,the error of rotation speed is the smallest.By dynamics analysis,when 1.2r0〈b〈1.8r0,the gear pair has the best transmission stability,load capacity and the best performance.Therefore,the theoretical basis for the design of cylindrical gears with arcuate tooth trace under the high speed and heavy load condition is provided by this analysis method and has engineering applications value.
