【摘要】：精密伺服减速器具有体积小、精度高、回差小、刚度高等特点,被广泛应用于机器人、机床、医疗、军工和包装印刷等行业。但精密伺服减速器的齿轮模数较小、转速范围宽、承受变载荷,易发生疲劳破坏。针对精密伺服减速器的特点,利用动力学和有限元联合仿真的方法,得到行星传动系统齿轮动态啮合力和系统的疲劳寿命。结果表明作为系统薄弱环节的太阳轮能很好的满足设计使用要求。采用动力学和有限元联合仿真方法利用系统动态啮合力来分析精密伺服减速器的疲劳寿命,更加符合减速器的实际工况,能够为产品的设计开发提供依据。
[Abstract]:Precision servo reducer is widely used in robot, machine tool and medical treatment because of its small volume, high precision, small return difference, high stiffness and so on. Military industry and packaging and printing industries. But the precision servo reducer gear module is small, the speed range is wide, bear variable load, easy to fatigue damage. According to the characteristics of precision servo reducer. The method of dynamic and finite element simulation is used. The dynamic meshing force and fatigue life of the gear in planetary transmission system are obtained. The results show that the sun wheel, which is the weak link of the system, can meet the design requirements well. The dynamic meshing force of the system is used to analyze the fatigue life of the precision servo reducer. More in line with the actual working conditions of the reducer, can provide the basis for product design and development.
