1、普通车床主轴箱设计 第 1 页 共 39 页毕 业 设 计 (论 文)专 业 机械设计制造及其自动化 班 级 机自 071 学生姓名 学 号 课 题 车床主轴箱设计 指导教师 2010 年 12 月 11 日普通车床主轴箱设计 第 2 页 共 39 页摘要普通中型车床主轴箱设计普通中型车床主轴箱设计，主要包括三方面的设计，即：根据设计题目所给定的机床用途、规格、主轴极限转速、转速数列公比或级数，确定其他有关运动参数，选定主轴各级转速值；通过分析比较，选择传动方案；拟定结构式或结构网，拟定转速图；确定齿轮齿数及带轮直径；绘制传动系统图。其次，根据机床类型和电动机功率，确定主轴及各传动件的计算转速
2、，初定传动轴直径、齿轮模数，确定传动带型号及根数，摩擦片尺寸及数目；装配草图完成后要验算传动件（传动轴、主轴、齿轮、滚动轴承）的刚度、强度或寿命。最后，完成运动设计和动力设计后，要将主传动方案“结构化” ，设计主轴变速箱装配图及零件图，侧重进行传动轴组件、主轴组件、变速机构、箱体、润滑与密封、传动轴及滑移齿轮零件的设计。【关键词】车床、主轴箱、变速系统、主轴组件。普通车床主轴箱设计 第 3 页 共 39 页ABSTRACTThe common and medium-sized lather principal axis box designCommon and medium-sized lat
