1、轴承套圈专用车床主轴箱设计摘要作为主耍的车削加工车床，轴承套圈专用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、短轴类、套类等零件，在该机床上采用多把刀具同时加工零件，也可采用仿型刀架加工各种成型表而。本设计主要针对液压卡盘多刀仿型车床主传动系统进行设计。主传动系统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、变向等。主传动系统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，釆用齿轮传动副；后者用来使主轴变速，釆用滑移齿轮变速机构，•其结构简单紧凑
2、，传动效率高。开停装置用于控制主轴的起动和停止。换向装置用于改变主轴的旋转方向。设计的内容主耍冇机床主要参数的确定，传动方案和传动系统图的拟定，对双向片式摩擦离合器进行设计，它是主轴的起动和停止以及换向装置，对离合器的主要零件摩擦片进行计算和验算，利用CAD绘图软件进行零件的设计和处理。关键词：车床，床头箱，换向，离合器。HYDRAULICMULTI-CHUCKLATHEBEDPROFILINGTOOLBOXDESIGNABSTRACTAsthemainlatheworklathe,speciallathesbearingringsarcsuita
