毕业设计(论文)带式输送机v带传动及一级直齿圆柱齿轮减速器的设计

内蒙古化工职业学院毕业论文题目：带式输送机V带传动及一级直齿圆柱齿轮减速器的设计系部：测控与机电工程系专业：机电一体化班级：机电09-2班学号：学生姓名：指导教师：——内蒙古化工职业学院毕业设计(论文、专题实验)任务书摘要带式输送机一级圆柱齿轮的设计是我们的毕业设计题目。

也是我们对对大学所学课程的一次深入的的综合性连接，也是一次理论联系实际的训练。

更是我们全方面地进行机械传动系统运动学、动力学分析和机械结构的设计的一个十分重要实践性的环节。

因此它是我们的大学生涯中占有十分重要的地位。

我希望通过这次毕业设计可以对自己在将来从事的工作进行一次适应性的训练。

从中可以锻炼自己分析问题、解决问题的能力。

为今后参加工作打下良好的基础。

装订线一.设计任务书
给定电动机型号、鼓风机轴转速和一天工作时间，要求设计合适的V带传动装置，完成电动机功率向鼓风机的传递。

主要设计计算内容有：确定带的型号、长度、根数，带轮直径，带传动中心距，作用在轴上的压力等；结构设计内容有：V带轮的材料、结构形式、基本尺寸等。

二.传动方案的拟定及说明
主动带轮1装在电动机轴上，从动带轮2装在鼓风机轴上，两带轮中心的水平距离a约等于大带轮直径d2的2倍。

线F d0=121 N。

带轮材料选择HT150，主动轮和从动轮都选取腹板式带轮。
