I電主軸的機械設計摘要 本文主要介紹了電主軸的工作原理、軸的設計、軸承技術以及關鍵技術等。電主軸就是直接將空心的電動機轉子裝在主軸上，定子通過冷卻套固定在主軸箱體孔內，形成一個完整的主軸單元，通電后轉子直接帶動主軸運轉。它主要應用在復合加工機床、多軸聯動、多面體加工機床和并聯機床中。本設計通過利用網絡工具、圖書館的書籍和各類期刊、雜志查閱了電主軸的相關知識，確定本設計符合要求，滿足需要。設計方法有：查閱資料產生電主軸機械設計的基本思路，確定合理的電主軸結構；重點對電主軸的軸進行了設計，對軸承進行了分析選配，確定了電主軸軸承的選配原則；且充分利用相關知識按要求對本課題進行具體設計。本設計采用的方法是理論設計與經驗設計相結合的方案，所運用的資料來源廣泛，內容充足。實現本方案的可行性高。實踐表明，所設計的 MS24015 銑床主軸滿足使用要求。關鍵詞 電主軸 定子 轉子 關鍵技術 動平衡The mechanic designs of electric spindlesIIAbstract 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 satisfies the request. Keywords: Electrical main shaft Stator Rotor Crucial technology Dynamic balancing
