齿轮油泵零件造型及结构设计
摘???要:齿轮油泵是通过一对参数和结构相同的渐开线齿轮的相互滚动啮合，将油箱内的低压油升至能做功的高压油的重要部件。是把发动机的机械能转换成液压能的动力装置。齿轮油泵由于其结构简单、制造容易、成本低，因此在国内是应用相当广泛的能用机械产品，而以外啮合泵应用最广。本分析报告中主要对油泵的齿轮、轴承、后盖、泵体进行分析，经过对零件的分析、测量和讨论，画出零件手绘图，；再经过查阅和分析有关参考书、手册、图表等技术资料，作出以下零件的功能、材料、尺寸、受CJK0615系列经济型数控车床进给伺服系统设计
摘要 ：数控机床在中国从产品范围、技术水平、质量和生产取得了很大的发展,也取得了重大突破领域的一些关键技术。但我国从80年代开始开始,先天不足,在项目开发上的高端机床落后于外国主流水平,现在还在追求发展的阶段。又由于目前我国资金短缺,行业规模较小的特点,规模较小的基金迅速改变落后的生产机械行业已成为一个必须的任务,和有效的方法来完成这一任务是经济型数控机床的推广应用。
经济型数控车床具有优越的价格,价格低,并具有更好的准确性和早期满足企业发展的需要,受到企业的青睐和私人。为我们的国家或经济欠发达,经济、合理、经济的数控车床符合中国国情。
伺服给水系统作为数控机床的重要组成部分,它是移动部件的位置和速度作为自动控制系统控制量,决定了工件的加工精度。

CJK0615 series economical nc lathe feed servo system design
Abstract:NC machine tool in China from both the product variety, technical level, quality and yield have achieved great development, A major breakthrough has been made on some key technology. But our country from twentieth Century 80 time just started,be congenitally deficient.Has been in the high-end machine tool project development lags behind theforeign mainstream standards, now still pursue development stage.And because our country at present the shortage of funds, the features of industrial scale is smaller, with a smaller funds quickly change the backwardproduction features of mechanical industry has become a must task, the effective ways to realize this task is the popularization and application ofeconomic NC machine tool.
Economic type CNC lathe has a superior cost-effective, low price, and has a high accuracy, to meet the needs of the beginning of the development of enterprises, by enterprise and private favor.For the Chinese economy is still not very developed, the economic type CNC lathe economic and reasonable, to meet the conditions of our country.
Servo feed system as an important part of the NC machine tool, it is based onthe moving parts of the position and speed of the automatic control system forthe control quantity, determines the machining accuracy of workpiece.

力和生产方式的分析，从国外先进技术和经验中吸取长处、积极探索，在设计中培养自己分析问题、解决问题的能力，力争独立思考、勇于创新，为今后的工作打下一个良好的基础。
齿轮油泵的发展历史：公元前100年左右就有了类似齿轮油泵的工业用具，据说是古希腊工匠克特西比乌斯发明的灭火泵是一种最原始的活塞泵，已具备典型活塞泵的主要元件，但活塞泵只是在出现了蒸汽机之后才得到迅速发展。
1840～1850年，美国沃辛顿发明泵缸和蒸汽缸对置的，蒸汽直接作用的活塞泵，标志着现代活塞泵的形成。然而随着需水量的剧增，从20世纪20年代起，低速的、流量受到很大限制的活塞泵逐渐被高速的离心泵和回转泵所代替.国内的第一台齿轮泵生产在原泊头市齿轮油泵总厂，在2005年已正式改名为河北恒盛泵业股份有限公司。早在1588年就有了关于四叶片滑片泵的记载，以后陆续出现了其他各种回转泵，但直到19世纪回转泵仍存在泄漏大、磨损大和效率低等缺点。
1689年，法国物理学家帕潘发明了四叶片叶轮的蜗壳离心泵。但更接近于现代离心泵的，则是1818年在美国出现的具有径向直叶片、半开式双吸叶轮和蜗壳的所谓马萨诸塞泵。现在的离心泵已经可以现实了自吸，多吸。立式以及卧式多种用途。1851～1875年，带有导叶的多级离心泵相继被发明，使得发展高扬程离心泵成为可能。
