摘要

現(xiàn)今的世界國家間的競爭已經(jīng)全面轉(zhuǎn)入科學(xué)技術(shù)的競爭，而機(jī)械工業(yè)直接反應(yīng)一個國家的整體技術(shù)水平。無論是核工業(yè)還是農(nóng)具，機(jī)械制造業(yè)是國家獲取其他幾乎一切行業(yè)設(shè)施和工具的來源。可以說人類文明史就是機(jī)械制造的歷史。
我國的工業(yè)化建設(shè)情況，國際上眾說紛紜，雖然在很多高技術(shù)項目上頗有建樹，但在這次汶川地震中表現(xiàn)出中眾多缺陷。包括規(guī)模較小，工藝粗糙，關(guān)鍵技術(shù)仍依賴國外等等。充分說明在向高技術(shù)領(lǐng)域進(jìn)軍的同時，低端產(chǎn)業(yè)也應(yīng)該加強(qiáng)建設(shè)。
本說明書是為加工機(jī)械零件偏心套的加工過程而編寫。偏心套以其偏心結(jié)構(gòu)實現(xiàn)內(nèi)孔直徑可調(diào)，加上緊定螺絲，以達(dá)到內(nèi)圈周向、軸向固定的目的。但因為內(nèi)圈內(nèi)孔是間隙配合，一般只用于輕載、無沖擊的場合。是一種較為常見的機(jī)械零件。

ABSTRACT
Nowadays,the competition of world countries has shift to the competition of new science and technology completely,In this age , level of development for the machine industry has become the most important criteria in the judgement in a country’s level of development.From Nuclear industry to dead stock,ALL the establishment and facilities,hat our country need and consume, depend on our machine industry .The histroy of mankind is the histroy of the machine building
Consider chinese industry construction,Many argumentations has been bring forward in the globality organization.We enjoy our achievement in some new technologes.But in these serious earthquake in WENCHUAN,we discovered our weakness: dimensions, asperous technics,core technology depend on other countries.So notwithstanding these is the age of advanced krowlage,we must improve our well-rounded technologies.
These instruction book is for machine hardware eccentric bushing’s processing cycle . The eccentric bushing with their proprietary composition accommodate inside diameter ,use the screw to realize the accommodate of inner ring’s lock-up.Byt bacause their clearance fit composition, they apply to non- or light- load.They are a type of frequently-used machine hardware.

Key word : eccentric bushing , machine hardware, processing cycle
