| 摘 要： | 考虑了齿轮体在各个方向的线振动和角振动,以及齿轮辐板和输入轴、输出轴的扭转变形,以弧齿锥齿轮传动系为对象,建立了一个多刚体多自由度的振动系统模型,推导了这一系统的参数激励微分方程组。再将方程组转化为线性定常的形式,并将参数激励转化为外激励,成功地求解了弧齿锥齿轮传动系统的振动过程。

| Abstract: | A dynamic model of tranxmission of spiral bevel gears is established.The model involves linear and angular vibrations of gears in every direction. Torsional deformations of webs of gears and input,output-shafts are considered.The governing equations of this model derived in this paper are multifreedom,timevarying and parametric differential equations。Purther,after neglecting the second order small components,they are transformed into constant coefficlent equa-tions,and:olved successfully. The dynamic responses and loads on gears in transmission are ob-tained.The dynamic loads at variable speeds of gears make up the dynamic behaviour of this pair of gears,which provides the basis for structural vibrations and strength analysis of spiral bevel gears. |
