重庆理工大学毕业设计 锅炉链条炉排变速器锅炉用链条炉排变速器锅炉用链条炉排变速器 毕业设计毕业设计摘摘要要锅炉链条炉排传动的变速箱是一种专用于为锅炉配套的机械传动设备链条炉排变速箱。本次设计运用行星齿轮传动的质量小、体积小、传动比大、承载能力大以及传动平稳和传动效率高等优点，采用 2K-H 型行星齿轮传动。它主要用于与锅炉主机呈直联侧安装形式，由电动机、一级圆柱齿轮副减速机构、过载安全保护装置、少齿差减速机构、联轴器等组成。安装时它直接安装在锅炉炉排的侧面，与炉排联结为一个整体，可统一试车，整体运输，避免用户二次安装引起的安装误差等弊端。设计由传动比入手设计内外齿轮及输入输出轴，后校验个零件的设计参数，生成CAD 装配图，最后生成 UG 三维图。关键词：少齿差 行星齿轮变速器 链条炉排变速器 UG重庆理工大学毕业设计 锅炉链条炉排变速器ABSTRACTGearbox drive chain grate boiler is a boiler dedicated to supporting mechanical equipment - chain grate gearbox. It is mainly used for direct connection with the boiler was the host side mounting form. It consists of motor, a cylindrical gear reduction mechanism, the overload protection device, small teeth difference deceleration mechanism, couplings and other components. It is mounted directly on the installation side of the boiler grate, coupled with the grate as a whole, can be unified test, the overall transport, to avoid user secondary installation errors and other defects caused by installation.The planetary gear drive design using quality, small size, large transmission ratio, load capacity and stable transmission and transmission efficiency advantages, the use of 2K-H planetary gear transmission, starting from the design of internal and external gear transmission ratio and the input and output shafts , a part of the design after the calibration parameters to generate CAD assembly diagram UG last generation of three-dimensional map.Keywords: small teeth difference planetary gear transmission chain grate transmission UG重庆理工大学毕业设计 锅炉链条炉排变速器目录目录一.绪论.31.课题背景.32 .发展概况.33.研究手段和可行性.3二.结构设计.31.电动机和变速器的选择及确定 .32.齿轮传动设计.33. 轴的设计.34.轴的验算.35.键的选择与强度校核.36.机构传动效率计算.37.变速器机座设计及其附件设计 .3三.三维绘图.31.绘图工具.32.主要零件的绘图.33.变速器装配图.3四.变速器的保养和维护.31.变速器润滑与冷却.32.润滑油的选用和方式的确定 .33.润滑油的使用要求.34.润滑油的维护.35.变速器的冷却.36.变速器的各项要求.3五.结论.3 致谢.3 参考文献.
