小轴承套圈专用车床主传动系统设计摘要作为主要的车削加工车床，轴承套圈车床是适合大批量生产，大功率，高效率的半自动化车床它主要用于轴承套圈的车削加工，也可用于加工盘类、套类等零件，在该机床上采用多把刀具同时加工零件，也采用仿型刀架加工各种成型表面。本设计主要针对轴承套圈车床床头箱进行设计。床头箱的功用是支撑主轴和传动其旋转并使其实现起动、停止、变速等。床头箱中的传动机构包括定比机构和变速机构两部分，前者仅用于传递运动和动力，或进行升速、降速，采用齿轮传动副；后者用来使主轴变速，采用塔轮和滑移齿轮变速机构，其结构简单紧凑，传动效率高。设计的内容主要有机床主要参数的确定，传动方案和传动系统图的拟定，对主要零件进行计算和验算，利用CAD绘图软件进行零件的设计和处理，最终完成对本课题的设计，并使其能够满足设计要求。关键词：数控机床，床头箱，轴承套圈BEARING DESING CNC LATHEABSTRACTAs a major turning lathe, Bearing ferrule lathe are suitable for mass production, high power, high efficiency is mainly used for semi-automatic lathe turning bearing ring can also be used in processing plates, short axis type, cover type and other parts in the machine tool bed, while the processing of multi-component, also used a variety of molding processing profiling tool carrier surface.This design is mainly for bearing ferrule lathe bed box. Headstock spindle function is to support and drive the rotation and make it start, stop, speed and so on. Headstock in fixed ratio transmission mechanism including the two institutions and the speed change mechanism, which is used only for the transfer movement and power, or acceleration, deceleration, with gear transmission; the latter used to make the spindle speed, sliding gear speed change mechanism, its simple and compact, high transmission efficiency. Designed mainly to determine the main parameters of a machine, transmission drive system diagram of the development program and, on the main parts of the calculation and checking friction plate, using CAD drawing software to design parts and processing, the final completion of the design of this issue and make its ability to meet the design requirements.KEY WORDS: Bearing ferrule lathe, bed box, bearing ring目　录前　言1第1章概述21.1设计目的21.2机床用途21.3滚动轴承套圈制造技术21.4滚动轴承滚动体制造技术5第2章机床运动分析92.1极限转速的确定92.2 转速系数公比的确定102.3 主电机功率的确定102.4 主传动系统的拟定11第3章主要零件的设计计算173.1 三角胶带传动的计算173.2传动轴的计算193.3 Ⅱ轴的计算203.4Ⅱ轴上轴承寿命验算283.5 主轴的计算313.6 齿轮的计算39第4章主轴箱的结构设计44第5章维修与保养455.1 润滑与密封455.2 其它问题45结　论46谢辞47参考文献48外文资
