攀枝花学院本科毕业设计 矿车车轮轴承外圈拆卸机设计 学生姓名： 袁国洪 学生学号： 200310621093 院 （系）： 机电工程学院 年级专业：03机械设计制造及其自动化 指导教师： 杨光春 高级工程师 助理指导教师： 二〇〇七年六月 摘 要 矿车车轮轴承外圈拆卸机是针对拆卸矿车车轮锥轴承外圈的专用机械设备。目前，我国很多矿厂还采用原始的大锤敲击的方法来拆卸轴承外圈，随着在我国矿业现代化的发展，这种原始的拆卸方法已不能满足我国矿厂实际生产的需要，各矿厂经常因损坏的矿车不能及时被修好而影响生产。因此，设计矿车车轮轴承外圈拆卸机具有重要的意义。设计中着重进行了液压系统的设计、拉(推)爪的结构设计、拆卸机机架的设计，同时对液压系统、拉（推）爪、机架进行了必要的校核，进而实现了拆卸轴承外圈的功能。 关键词 拆卸机，结构，设计，液压系统  ABSTRACT The mine car wheel bearing addendum circle disassemblage machine isaims at the disassemblage mine car wheel awl bearing addendum circlethe special-purpose mechanical device. At present, our country verymany mines also use the method which the primitive sledgehammer rapsto disassemble the bearing addendum circle, along with in our countrymining industry modernization development, this primitivedisassemblage method has not been able to satisfy the our countrymine actual production the need, various mines frequently becausedamage the mine car cannot promptly fix affects the production.Therefore, designs the mine car wheel bearing addendum circledisassemblage machines and tools to have the vital significance. Inthe design emphatically carried on the hydraulic system design, haspulled the fingernail the structural design, the disassemblage machinerack design, simultaneously to the hydraulic system, pulled thefingernail, the rack has carried on the essential examination, thenhas realized the disassemblage bearing addendum circle function. Keywords disassemblage machine, structure, design, hydraulic system  目 录 摘 要……………………………………………………………………………………………Ⅰ ABSTRACT…………………………………………………………………………………… Ⅱ 1 绪论……………………………………………………………………………………………1 1.1 现状调查 …………………………………………………………………………………1 1.2 拆卸机设计的意义………………………………………………………………………1 2 方案设计……………………………………………………………………………3 2.1 装配图的分析………………………………………………………………………………3 2.2 方案设计…………………………………………………………………………………3 3 拆卸力的计算……………………………………………………………………5 3.1 计算最大过盈量…………………………………………………………………………5 3.2 计算拆卸力…………………………
