蜗轮蜗杆减速器设计

摘要

通过对减速器的简单了解，开始学习设计齿轮减速器，尝试设计增强感性认知和对社会的适应能力，及进一步巩固已学过的理论知识，提高综合运用所学知识发现问

题、解决问题，以求把理论和实践结合一起，为以后的工作和更好的学习积累经验。学习如何进行机械设计，了解机械传动装置的原理及参数搭配。学习运用多种工具，比如CAD等，直观的呈现在平面图上。通过对圆柱齿轮减速器的设计，对齿轮减速器有个简单的了解与认知。齿轮减速器是机械传动装置中不可缺少的一部分。机械传动装置在不断的使用过程中，会不同程度的磨损，因此要经常对机械予以维护和保养，延长其使用寿命，高效化的运行，提高生产的效率，降低生产的成本，获得最大的使用效率。

关键词：机械传动装置、齿轮减速器、设计原理与参数配置
