摘　　要：以圆弧齿线圆柱齿轮为研究对象,为了获得圆弧齿线圆柱齿轮的啮合接触冲击特性。基于接触动力学相关理论和齿轮传动物理模型,提出了圆弧齿线圆柱齿轮传动啮合接触冲击的假说,并建立齿轮啮合接触冲击模型;给出可以解决冲击碰撞问题的有限元分析方法,通过圆弧齿线圆柱齿轮齿面数学模型建立精确三维数字样机,进而建立啮合接触冲击显示动态有限元模型,研究冲击速度、冲击位置与冲击应力、冲击合力以及冲击时间的关系。研究表明冲击速度和冲击位置的变化对冲击应力、冲击合力和冲击时间均产生了一定的影响。研究结果为圆弧齿线圆柱齿轮的动态设计和工业应用提供了理论基础。Taking circular arc tooth trace(CATT)cylindrical gears as a study object,in order to get CATT cylindrical gears’mesh contact impact features,the mesh contact impact hypothesis of CATT cylindrical gears was put forward based on the contact dynamics theory and the gears transmission physical model to establish a gears’mesh contact impact model.A finite element method was proposed to solve this contact impact problem.According to the tooth surface mathematic model of CATT cylindrical gears,the accurate 3-D digital prototype was established,then the dynamic finite element model to reveal the mesh contact impact process was built to study relations among impact velocity,impact location,impact stress,impact resultant and impact time.The results showed that impact velocity and impact location have a certain influence on impact stress,impact resultant and impact time.The study results provided a theoretical basis for dynamic design and industrial applications of CATT cylindrical gears.
