1、 I 卧式车床主轴箱设计 摘 要 金属切削机床在国民经济现代化建设中起着重大的作用。机床技术水平的高 低已成为衡量一个国家工业现代化水平的重要标志之一。机床工业是机械制造业 的“装备部” ，对国民经济的发展起着重大作用。 本论文设计的主轴箱的变速级数是 12 级，传动比为 1.41，转速从 31.5r/min 到 1440r/min，加工工件的最大直径为 400mm， 。论文对箱体内结构进行方案设计， 并对传动方案、传动路线进行了分析，离合器、带轮、润滑系统、密封装置等进 行了设计、计算及校核。 本设计的主要内容包括：1.运动设计：确定主轴的转速、拟定合理结构式、结 构网和转速图、确定齿轮的齿

2、数、皮带轮的设计计算以及实际转速和标准速偏差 的校核等。2.动力设计：估算各传动轴的转速、估算各轴的直径、选择电动机、齿 轮强度验算、主轴刚度的校核、轴承寿命的验算、选择离合器。3.结构设计：确定 各传动组件的空间布置。 关键词：主轴箱，齿轮，摩擦式离合器 II HORIZONTAL LATHE SPINDLE BOX DESIGN ABSTRACT Metal-cutting machine tool in the modernization of the national economy plays an important role.
