立式数控铣床主传动系统设计
[摘要]本文介绍了数控铣床的一些基本概况，简述了数控机床主传动系统方面的原理和类型，分析了各种传动方案的机理。数控铣床主传动系统包括了主轴电动机、主轴传动系统和主轴组件三部分组成。本文详细介绍了数控铣床主传动系统的设计过程，该数控铣床主轴变速箱是靠齿轮进行传动的，主轴箱传动系统采用齿轮传动，传动形式采用集中式传动，主轴变速系统采用多联滑移齿轮变速。齿轮传动具有传动效率高，结构紧凑，工作可靠、寿命长，传动比准确等优点。文中介绍了数控铣床主传动系统各种传动方案优缺点的比较、主传动方案的选择和确定、主传动变速系统的设计计算、主轴组件的设计、轴承的选用基润滑、关键零件的校核、以及主轴电动机的控制等设计过程。
