- 摘要:
- 基于蜗杆传动的弹流润滑,建立了蜗杆传动的理论模型.采用复合直接迭代法求解最小油膜厚度,并利用MATLAB软件对最小油膜厚度进行了计算,探讨了蜗轮蜗杆的关键性参数对油膜厚度的影响.研究结果表明:在数值选取范围内,最小油膜厚度随蜗杆分度圆导程角、蜗杆头数、转速及蜗轮直径的增大而增大,随蜗杆输入功率和载荷系数的增大而减小; 蜗杆齿顶圆上的最小油膜厚度比齿根圆上最小油膜厚度大; 将本文的强度设计公式(5)和润滑设计公式(8)进行联立计算,得到摩擦学设计公式.
- Abstract:
- The theoretical model of worm drive is established by worm drive EHL theory. The composite direct iterative method is used for calculating minimum oil film thickness by MATLAB software.Key parameters of worm drive are used for researching the influence of minimum oil film thickness. The results show that in the range of effective parameters,minimum oil film thickness is more with increasing worm lead angle,number of threads, rotating speed, worm gear diameter and is less with increasing worm input power and load coefficient. Minimum oil film thickness of worm tooth crest is bigger than that of tooth root.Strength formula(5)and lubrication formula(8)are calculated to obtain friction formula.
