摘要
基于现代先进汽车电动助力转向(Electric Power Steering,EPS)系统对转向传动的特殊要求,传动平稳、噪声小、成本低的尼龙斜齿轮钢蜗杆传动得到大量应用,但由于其材料特殊,传统的蜗轮蜗杆设计方法准则并不适用。通过分析尼龙斜齿轮钢蜗杆传动的特殊情况,综合考虑性能、结构、成本等因素,借助Kisssoft软件对给定条件下的斜齿轮蜗杆传动机构的结构参数、安全系数进行了设计分析;按照易加工、不失效、等强度的原则,提出了其合理变位系数的取值及斜齿轮蜗杆各参数的设计方法,并利用Workbench软件对设计出的模型进行了仿真验证。结果表明,优化后的尼龙斜齿轮钢蜗杆传动满足设计要求,综合性能较优。
Based on special requirements of modern advanced automobile electric power steering(EPS)for steering transmission,the nylon helical gear steel worm transmission with stable transmission,low noise and low cost has been widely used.However,due to its special material,the traditional design method of worm gears is not applicable.In this study,by analyzing the special situation of the nylon helical gear steel worm transmis-sion,considering some factors such as performance,structure and cost,structural parameters and safety factors of the helical gear worm transmission mechanism under given conditions are designed and analyzed by Kisssoft software.According to the principle of easy processing,no failure and equal strength,the value of reasonable modification coefficient and the design method of each parameter of helical gear are put forward,and the model is simulated and verified by Workbench software.The results show that the optimized nylon helical gear steel worm transmission meets the design requirements and has better comprehensive performance.
