圖紙和說明書都有

　摘要
　　　在機械制造工業(yè)中，由于被加工零件形狀和表面以及精度要求的不同而發(fā)展、產生了種類繁多的金屬切削機床。在生產實際中大量使用銑床、磨床、鉆床、鏜床以及直線運動機床等。
　　　數控機床是裝備制造業(yè)的工作母機，是實現制造技術和裝備現代化的基石，是保證高新技術產業(yè)發(fā)展和國防軍工現代化的戰(zhàn)略裝備。在全球倡導綠色制造的大環(huán)境下，機床數控化改造成為了熱點。
　　　課程設計是在學生學完相應課程及先行課程之后進行的實習性教學環(huán)節(jié)，是大學生的必修環(huán)節(jié)，其目的在于通過機床運動機械變速傳動系統(tǒng)的結構設計，使學生在擬定傳動和變速的結構方案過程中，得到設計構思，方案分析，結構工藝性，機械制圖，零件計算，編寫技術文件和查閱技術資料等方面的綜合訓練，樹立正確的設計思想，掌握基本的設計方法，并培養(yǎng)學生具有初步的結構分析，結構設計和計算能力。
　　　本次設計是對端面銑床主軸箱做了全面設計，對主軸箱內部各部件（包括傳動軸、主軸、齒輪、軸承等）做了詳細的設計與校核，使其滿足實際生產工作的需要。

Abstract
　　　In machine manufacture industry，because is processed the components shape and surface as well as the precision request different develops、has produced the type many metal cutting engine bed. Is producing actual massive uses the milling machine、the grinder、the drilling machine、the boring lathe as well as the translation engine bed and so on.
　　　NC(numerical control) machine tools is the Machine Tools and equipment manufacturing, is to achieve manufacturing technology and the cornerstone of modern equipment is to ensure that high-tech industry development and national defense modernization of the military strategy and equipment. Green Manufacturing in the global advocacy of the environment, transformation of CNC machine tools to become a hot spot.
　　　The curriculum design is the practice teaching link which carries on afterwards in the student study corresponding curriculum and the advance curriculum, is university student's compulsory link, its goal lies in through the engine bed movement power shifting transmission system structural design, causes the student in to draw up the transmission and in the speed change structure plan process, obtains the design idea, the plan analysis, the structure technology capability, the mechanical drawing, the components computation, the compilation technology document and aspect and so on consult technical data integrated trainings, set up the correct design concept, grasps the basic design method, and trains the student to have the preliminary structure analysis, the structural design and computation ability.
　　　This design is an end milling machine main axle box for a comprehensive design.Within the various parts of the spindle box (including shaft,gear,shaft,bearing)made a detailed design and proofread,to meet the needs of the actual production work.
