1、.XX科技学院专科毕业设计论文题 目带式输送机传送装置学生姓名 李伟 专业班级 08机制三班 学 号 200824126 所 在 系 机械工程系 指导教师 杨晨 完成时间 2011年3月28日.带式输送机传送装置摘要运输机械用减速器/T9002-1999包括：二级传动硬齿面DBY和中硬齿面DBZ两个系列及三级传动硬齿面DCY和中硬齿面DCZ两个系列。第一级传动为锥齿轮,第二、第三级传动为渐开线圆柱齿轮。锥齿轮齿形为格里森弧线齿或克林根贝尔格延伸外摆线齿。齿轮及齿轮轴均采用优质合金钢锻件。硬齿面经渗碳、淬火磨齿,齿面硬度为：齿轮轴58-62HRC；齿轮54-58HRC。圆柱和圆锥齿轮精度分别不低
2、于GB/T10095和GB/T11365中的6级。中硬齿面减速器的锥齿轮采用硬齿面,圆柱齿轮采用调质、精滚,齿面硬度为：齿轮轴306-332HB,大齿轮273-314HB,齿轮精度为7级。这种减速器主要适用于运输机械,也可用于冶金、矿山、石油、化工等通用机械.其工作条件为：a. 输入轴最高转速不大于1500r/min；b. 齿轮圆周速度不大于20m/s；c. 工作环境温度为-4045度,当环境温度低于0度时,启动前润滑油应预热。从以上资料我们可以看出齿轮减速器结构紧凑、传动效率高、运行平稳、传动比大、体积小、加工方便、寿命长等等.因此,随着我国社会主义建设的飞速发展,国内已有许多单位自行设计和
3、制造了这种减速器,并且已日益广泛地应用在国防、矿山、冶金、化工、纺织、起重运输、建筑工程、食品工业和仪表制造等工业部门的机械设备中,今后将会得到更加广泛的应用。本文首先介绍了带式输送机传动装置的研究背景,通过对参考文献进行详细的分析,阐述了齿轮、减速器等的相关内容；在技术路线中,论述齿轮和轴的选择及其基本参数的选择和几何尺寸的计算,两个主要强度的验算等在这次设计中所需要考虑的一些技术问题做了介绍；为毕业设计写作建立了进度表,为以后的设计工作提供了一个指导。最后,给出了一些参考文献,可以用来查阅相关的资料,给自己的设计带来方便。关键词电动机,齿轮,轴,圆锥-圆柱齿轮传动减速器BEIYCONVEV
