本科毕业设计(论文) 题目： 蜗轮蜗杆减速器的优化设计 摘要蜗轮蜗杆减速机是将电机的回转数减速到所要的回转数，并得到较大转矩的机构。目前用于传递动力与运动的机构中，应用范围相当广泛应用MATLAB软件对不同齿数和模数进行根切量的精确计算,并关键词：、蜗轮蜗杆减速器、蜗杆、蜗轮、键、 ABSTRACT This article of graduation design paper is about the worm gear and worm reducer optimization. Worm gearbox is the number of motor slowdown to turn to turn the number, and to get bigger torque of institutions. Currently used to deliver power and movement organization, application scope very wide. Therefore, the optimization worm gear and worm reducer to produce economic benefits and social resource conservation is very meaningful. This paper first through the required speed motor and power calculation, combine the look-up table choose the proper motor. Then, using software MATLAB and modulus of different number of parameters, such as cutting the precise amount root, and select the optimal parameters. According to the economic benefits to choose the appropriate material. Again, according to the material for input shaft and the design of the output shaft, check out with Ansys analysis, choose the right axis. Finally, according to the size of the load through calculation choose appropriate bearing and shaft parts. Do the seal and reducer to the life of gear reducer daily lubrication is very important also. Through optimizing design of worm gear and worm reducer in function, efficiency and ordinary worm gear and worm reducer, but in production through the choice of materials can prevent waste materials and the economic optimization. Key words: root cut, worm gear and worm reducer, worm and worm and keys, the speed 目录 摘要 I ABSTRACT II 1 绪论 1 1.1设计参数 1 1.2设计研究意义 1 1.3系统运动方案的设计 1 2 电动机的选择及传动比 3 2.1电动机类型的选择 3 2.2电动机功率选择 3 2.3确定电动机型号 3 2.4主要动力参数的计算 4 2.4.1传动参数的计算 4 2.4.2蜗杆蜗轮的转速 5 2.4.3功率 5 2.4.4转矩 5 3 传动零件的设计计算 6 3.1选择蜗杆传动类型 6 3.2选择材料 6 3.3蜗杆与蜗轮的主要参数与几何尺寸 6 3.4建立目标函数 7 3.5确定约束条件 7 3.5.1线形不等式约束条件 7 3.5.2非线性不等式约束条件 8 3.6蜗杆传动的热平衡计算 8 3.7编写程序 9 3.8结论 10 4 轴的设计计算 11 4.1高速轴(蜗杆轴)的设计计算 11 4.1.1先按扭转计算轴的最小直径 11 4.1.2联
