摘要

现今的世界国家间的竞争已经全面转入科学技术的竞争,而机械工业直接反应一个国家的整体技术水平。无论是核工业还是农具,机械制造业是国家获取其他几乎一切行业设施和工具的来源。可以说人类文明史就是机械制造的历史。
我国的工业化建设情况,国际上众说纷纭,虽然在很多高技术项目上颇有建树,但在这次汶川地震中表现出中众多缺陷。包括规模较小,工艺粗糙,关键技术仍依赖国外等等。充分说明在向高技术领域进军的同时,低端产业也应该加强建设。
本说明书是为加工机械零件偏心套的加工过程而编写。偏心套以其偏心结构实现内孔直径可调,加上紧定螺丝,以达到内圈周向、轴向固定的目的。但因为内圈内孔是间隙配合,一般只用于轻载、无冲击的场合。是一种较为常见的机械零件。

关键词:偏心套 零件 加工过程


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
