随着能源的日益紧张,节能已是一件十分重要的工作,在设计工作中进行节能的考虑是从根本上解决问题尤其重要。关于机床主轴轴系的设计,在过去的文献中往往考虑一个支承的功耗最小进行了很多工作,而在整个轴系中如何选择各种结构参数对节能最有利则考虑较少;本文主要叙述如何合理的选择轴承的长径比K/D,使整个轴系的功耗为较少。 As energy becomes more and more tense, energy conservation has become a very important task. Taking energy conservation into account in design work is a fundamental solution to the problem. Regarding the design of the spindle system of the machine tool spindle, a lot of work has been done in the past to consider the minimum power consumption of a support. However, it is considered that how to choose various structural parameters in the entire shaft system is most advantageous for energy saving. In this paper, How to choose a reasonable bearing aspect ratio K / D, the power consumption of the entire shaft system is less.
