内容简介：

电主轴的机械设计 摘要 本文主要介绍了电主轴的工作原理、轴的设计、轴承技术以及关键技术等。电主轴就是直接将空心的电动机转子装在主轴上，定子通过冷却套固定在主轴箱体孔内，形成一个完整的主轴单元，通电后转子直接带动主轴运转。它主要应用在复合加工机床、多轴联动、多面体加工机床和并联机床中。本设计通过利用网络工具、图书馆的书籍和各类期刊、杂志查阅了电主轴的相关知识，确定本设计符合要求，满足需要。设计方法有：查阅资料产生电主轴机械设计的基本思路，确定合理的电主轴结构；重点对电主轴的轴进行了设计，对轴承进行了分析选配，确定了电主轴轴承的选配原则；且充分利用相关知识按要求对本课题进行具体设计。本设计采用的方法是理论设计与经验设计相结合的方案，所运用的资料来源广泛，内容充足。实现本方案的可行性高。实践表明，所设计的MS24015铣床主轴满足使用要求。关键词 电主轴 定子 转子 关键技术 动平衡The mechanic designs of electric spindlesAbstract The designs and working principle of electric spindles 、bearing technical as well as crucial technology and so on was introduced in this paper . Electrical spindles is being made by a direct motor rotor of be hollow pack in main shaft on and stator knows super-cooling but cover fixes, which form a complete unit of main shaft in the casing hole of main shaft, and then the electricity rotor directly drive the operation of main shaft. Its main application is being compound process machine tool and much axle to unite to move, polyhedron processing machine tool and the machine tool of parallel connection in. This design cut the related knowledge of central fuselage according with requirement through using network tool and magazines , each kind of periodical and the books in the library and then determining the design, which satisfies the needs. The design method is as follows: First, look up information to produce the basic thought of the electrical mechanical design of main shaft, determine the reasonable electrical structure of main shaft. Then, the key axle for electrical main shaft is designed, and analyze and choose the match for bearing, the electrical bearing of main shaft choose to match principle have determined; Use related knowledge finally fully press requirement for this program carry out specific design. The method of designing adopted the scheme theoretical design and experience design, and the data sources utilized was adequate content extensively. Feasibility of realize the scheme is high. Practice shows that the MS24015 main shaft of milling machine design
