Research of the Dynamics of Varying-coefficient-shift-modification Gear based on ADAMS

以变变位齿轮传动系统为研究对象,对其进行了动态特性的研究。以MATLAB、Pro/E和ADAMS软件为工具,建立变变位齿轮传动的动力学仿真模型,得到其传动过程中的轮齿接触力变化曲线和振动特性曲线。仿真结果表明,变变位齿轮具有传动平稳、轮齿接触力及角加速度变化规律的特性,可有效地减小偏心齿轮因存在侧隙产生过大振动冲击的缺陷,在实际工程中具有重要的应用价值。

Taking the varying- coefficient- shift- modification gear transmission system as study object,the dynamic characteristics are studied. The dynamics simulation model of varying- coefficient- shift- modification gear transmission system is established based on the software of Matlab,Pro / E and ADAMS. The curves of changing contact force and vibration characteristic are obtained. The simulation results show that,the varying- coefficient- shift- modification gear has the characteristic transmission steady,contact force of gears and angular acceleration change regular. The vibration caused by the backlash of eccentric- involutes gears is effectively reduced,it has a strong application value in the practical engineering.
