1、CK514立式数控车床X向进给传动系统设计摘要随着世界科技进步和机床工业的发展，数控机床作为机床工业的主流产品，已成为实现装备制造业现代化的关键设备，是国防军工装备发展的战略物资。数控机床的拥有量及其性能水平的高低,是衡量一个国家综合实力的重要标志，所以发展数控机床的水平是现时代赋予我们机械类人员的使命。本课题是关于CK514立式数控车床X向进给传动系统的设计，设计内容包括：确定系统的负载，确定系统脉冲当量，运动部件惯量计算，空载起动及切削力矩计算，确定伺服电机，绘制机械部分装配图及零件工作图等。设计从传动方案的确
2、定，传动结构的选择，以及传动部件的选型等等方面逐一开展。进给传动伺服系统可分为三种：开环、半闭环和闭环伺服系统。通过比较，按照使用要求选用半闭环伺服系统。机械传动结构选用同步齿形带连接伺服电动机和丝杠，这种结构简单，传动扭矩大，并且传动误差小，经济性能好，符合设计要求。传动部件的选择包括导轨类型的选择及其使用要求，滚珠丝杠螺母副选型和伺服电动机的选择。关键词:数控车床进给系统导轨丝杠19X-axisfeedingsystemdesignofCK514CNClatheAbstractAlongwiththeworld
