2.6维修保养

由于采用了静液压传动系统,省去了液力传动推土机的变矩器、动力换挡变速器、中央传动、转向离合器及转向制动器等部件,大大简化了整机结构,使传动系统的维修保养非常方便。

为了便于对各液压系统测压,以助于维修保养,该机采用了集中测压方式,所有的测压点均设在左箱体内,打开箱体盖便可看见,非常方便。该机左右发动机罩、左箱体盖均采用油气弹簧支撑,打开时省时、省力。

机械设计 摘要:机器是由机械装置和其它组件组成的。它是一种用来转换或传递能量的装置,例如:发动机、涡轮机、车辆、起重机、印刷机、洗衣机、照相机和摄影机等。许多原则和设计方法不但适用于机器的设计,也适用于非机器的设计。术语中的“机械装置设计”的含义要比“机械设计”的含义更为广泛一些,机械装置设计包括机械设计。在分析运动及设计结构时,要把产品外型以及以后的保养也要考虑在机械设计中。在机械工程领域中,以及其它工程领域中,所有这些都需要机械设备,比如:开关、凸轮、阀门、船舶以及搅拌机等。 关键词:设计流程设计规则机械设计 设计流程 设计开始之前就要想到机器的实际性,现存的机器需要在耐用性、效率、重量、速度,或者成本上得到改善。新的机器必需具有以前机器所能执行的功能。 在设计的初始阶段,应该允许设计人员充分发挥创造性,不要受到任何约束。即使产生了许多不切实际的想法,也会在设计的早期,即在绘制图纸之前被改正掉。只有这样,才不致于阻断创新的思路。通常,还要提出几套设计方案,然后加以比较。很有可能在这个计划最后决定中,使用了某些不在计划之内的一些设想。 一般的当外型特点和组件部分的尺寸特点分析得透彻时,就可以全面的设计和分析。接着还要客观的分析机器性能的优越性,以及它的安全、重量、耐用性,并且竞争力的成本也要考虑在分析结果之内。每一个至关重要的部分要优化它的比例和尺寸,同时也要保持与其它组成部分相协调。 也要选择原材料和处理原材料的方法。通过力学原理来分析和实现这些重要的特性,如那些静态反应的能量和摩擦力的最佳利用,像动力惯性、加速动力和能量;包括弹性材料的强度、应力和刚度等材料的物理特性,以及流体润滑和驱动器的流体力学。设计的过程是重复和合作的过程,无论是正式或非正式的进行,对设计者来说每个阶段都很重要。 最后,以图样为设计的标准,并建立将来的模型。如果它的测试是符合事先要

液压系统及液压缸-外文翻译

液压传动 第十讲 制动器 力流体动力系统的优秀的特性之一是由电源产生,通过适当的控制和指导,并通过电线传输,就可以轻松转换到几乎任何类型的机械运动所需要用到的地方。使用一个合适的驱动装置,可以获得线性(直线)或者是旋转运动。驱动器是一种转换流体动力机械力和运动的装置。缸、马达和涡轮机是最常见的将流体动力系统应用于驱动设备的类型。这一章描述了各种类型的动作汽缸和他们的应用程序、不同类型的流体汽车和使用流体动力系统的涡轮机。 汽缸 制动汽缸是一种将流体动力转换成线性或直线、力和运动的装置。因为线性运动是沿着一条直线前后移动的往复运动。这种类型的制动器有时被称为一个往复、或线性、电动机。由ram或活塞组成的汽缸在一个圆柱孔内操作。制动汽缸可以安装,以便汽缸被固定在一个固定的结构,ram或活塞被连接到该机制来操作,或者是活塞和ram可能被固定到固定结构,汽缸附加到机械装置来操作。制动汽缸气动和液压系统的设计和操作是类似的。一些变化的ram和活塞式制动汽缸的内容将在后面的段落中描述。 冲压式缸 术语ram和活塞通常可以互换使用。然而,一个冲压式缸通常被认为是一个截面积活塞杆超过一半的截面积活动元件。在大多数这种类型的制动汽缸中,杆和活动元件各占一半。这种类型的活动元件经常被称为柱塞。冲压式缸主要是用来推动而不是拉。一些应用程序需要ram的一部分在平坦的外部来推动或升降单位操作。其他应用程序需要一些机械装置的附件,如一个U型夹或有眼螺栓。冲压式缸的设计在很多其他方面不同,以满足不同应用程序的要求。 单作用千斤顶 单作用千斤顶(如图:10-1)试用力只在一个方向。流体定向的汽缸取代ram 和他外部的弹性元件,将物体举起放在上面。

附录一英文科技文献翻译 英文原文: Experimental investigation of laser surface textured parallel thrust bearings Performance enhancements by laser surface texturing (LST) of parallel-thrust bearings is experimentally investigated. Test results are compared with a theoretical model and good correlation is found over the relevant operating conditions. A compari- son of the performance of unidirectional and bi-directional partial-LST bearings with that of a baseline, untextured bearing is presented showing the bene?ts of LST in terms of increased clearance and reduced friction. KEY WORDS: ?uid ?lm bearings, slider bearings, surface texturing 1. Introduction The classical theory of hydrodynamic lubrication yields linear (Couette) velocity distribution with zero pressure gradients between smooth parallel surfaces under steady-state sliding. This results in an unstable hydrodynamic ?lm that would collapse under any external force acting normal to the surfaces. However, experience shows that stable lubricating ?lms can develop between parallel sliding surfaces, generally because of some mechanism that relaxes one or more of the assumptions of the classical theory. A stable ?uid ?lm with su?cient load-carrying capacity in parallel sliding surfaces can be obtained, for example, with macro or micro surface structure of di?erent types. These include waviness [1] and protruding microasperities [2–4]. A good literature review on the subject can be found in Ref. [5]. More recently, laser surface texturing (LST) [6–8], as well as inlet roughening by longitudinal or transverse grooves [9] were suggested to provide load capacity in parallel sliding. The inlet roughness concept of Tonder [9] is based on ??e?ective clearance‘‘ reduction in the sliding direction and in this respect it is identical to the par- tial-LST concept described in ref. [10] for generating hydrostatic e?ect in high-pressure mechanical seals. Very recently Wang et al. [11] demonstrated experimentally a doubling of the load-carrying capacity for the surface- texture design by reactive ion etching of SiC

外文出处: 《Exploiting Software How to Break Code》By Greg Hoglund, Gary McGraw Publisher : Addison Wesley Pub Date : February 17, 2004 ISBN : 0-201-78695-8 译文标题: JDBC接口技术 译文: JDBC是一种可用于执行SQL语句的JavaAPI(ApplicationProgrammingInterface应用程序设计接口)。它由一些Java语言编写的类和界面组成。JDBC为数据库应用开发人员、数据库前台工具开发人员提供了一种标准的应用程序设计接口,使开发人员可以用纯Java语言编写完整的数据库应用程序。 一、ODBC到JDBC的发展历程 说到JDBC,很容易让人联想到另一个十分熟悉的字眼“ODBC”。它们之间有没有联系呢?如果有,那么它们之间又是怎样的关系呢? ODBC是OpenDatabaseConnectivity的英文简写。它是一种用来在相关或不相关的数据库管理系统(DBMS)中存取数据的,用C语言实现的,标准应用程序数据接口。通过ODBCAPI,应用程序可以存取保存在多种不同数据库管理系统(DBMS)中的数据,而不论每个DBMS使用了何种数据存储格式和编程接口。 1.ODBC的结构模型 ODBC的结构包括四个主要部分:应用程序接口、驱动器管理器、数据库驱动器和数据源。应用程序接口:屏蔽不同的ODBC数据库驱动器之间函数调用的差别,为用户提供统一的SQL编程接口。 驱动器管理器:为应用程序装载数据库驱动器。 数据库驱动器:实现ODBC的函数调用,提供对特定数据源的SQL请求。如果需要,数据库驱动器将修改应用程序的请求,使得请求符合相关的DBMS所支持的文法。 数据源:由用户想要存取的数据以及与它相关的操作系统、DBMS和用于访问DBMS的网络平台组成。 虽然ODBC驱动器管理器的主要目的是加载数据库驱动器,以便ODBC函数调用,但是数据库驱动器本身也执行ODBC函数调用,并与数据库相互配合。因此当应用系统发出调用与数据源进行连接时,数据库驱动器能管理通信协议。当建立起与数据源的连接时,数据库驱动器便能处理应用系统向DBMS发出的请求,对分析或发自数据源的设计进行必要的翻译,并将结果返回给应用系统。 2.JDBC的诞生 自从Java语言于1995年5月正式公布以来,Java风靡全球。出现大量的用java语言编写的程序,其中也包括数据库应用程序。由于没有一个Java语言的API,编程人员不得不在Java程序中加入C语言的ODBC函数调用。这就使很多Java的优秀特性无法充分发挥,比如平台无关性、面向对象特性等。随着越来越多的编程人员对Java语言的日益喜爱,越来越多的公司在Java程序开发上投入的精力日益增加,对java语言接口的访问数据库的API 的要求越来越强烈。也由于ODBC的有其不足之处,比如它并不容易使用,没有面向对象的特性等等,SUN公司决定开发一Java语言为接口的数据库应用程序开发接口。在JDK1.x 版本中,JDBC只是一个可选部件,到了JDK1.1公布时,SQL类包(也就是JDBCAPI)

外文资料 In recent years, the hydraulic motor with brachytely and big torsional moment has great changes, the new structure continuously appears. But, all these hydraulic motors can be divided into two broad categories of single and multi-role according to the role of the number of plunger in each turn. The motors also can be divided into radial and horizontal direction according to the arrangement of the plunger. And the radial motors can be divided into different types according to structure and the summon power way of the plunger. No matter single and multi-role, the plug-hole of radial-piston hydraulic motor is equated by circle, arrayed radial. The plunger displaced by the impulse of pressure oil, then the volume of the cylinder changed, the summon power formed the rotation of the motor, all of these above are the mechanism of action of the motors. The rotor of the single role hydraulic motor has a circle of rotation, each plunger worker once reciprocation. The principal axis is eccentric axis in all the radial-piston hydraulic motors. The multi-role hydraulic motor had a guide rail curve, whose numbers are the action times. The rotor had a circle of rotation, the plunger worker many times reciprocal at the same time. The radial motors can be divided into several categories of plunger, ball blocker, blade. The structure of the single-role motors is simpler, the machine element number of it is less, the technology is better, and the cost is less. But the structure dimension of the single-role motor is longer than the multi-role motor in the same displacement each turn (or output torsional moment), and the single-role motor also have fluctuation of the output torsional moment and rotary speed.The homonymy high-pressure column tune of the single-role motor had major radial unbalance force that causes the brachytely stabilization of the motor became worse. Only increasing the capacity of the bearing, it can meet the requirements of the operating life of the bearing at the same time.

塔式起重机外文翻译、中英对照、英汉互译

外文资料翻译译文 塔式起重机 动臂装在高耸塔身上部的旋转起重机。作业空间大,主要用于房屋建筑施工中物料的垂直和水平输送及建筑构件的安装。由金属结构、工作机构和电气系统三部分组成。金属结构包括塔身、动臂和底座等。工作机构有起升、变幅、回转和行走四部分。电气系统包括电动机、控制器、配电柜、连接线路、信号及照明装置等。 塔式起重机简称塔机,亦称塔吊,起源于西欧。据记载,第一项有关建筑用塔机专利颁发于1900 年。1905 年出现了塔身固定的装有臂架的起重机,1923 年制成了近代塔机的原型样机,同年出现第一台比较完整的近代塔机。1930 年当时德国已开始批量生产塔机,并用于建筑施工。1941 年,有关塔机的德国工业标准DIN8770 公布。该标准规定以吊载(t)和幅度(m)的乘积(tm)一起以重力矩表示塔机的起重能力。 我国的塔机行业于20 世纪50 年代开始起步,相对于中西欧国家由于建筑业疲软造成的塔机业的不景气, 上海波赫驱动系统有限公司我国的塔机业正处于一个迅速的发展时期。 从塔机的技术发展方面来看,虽然新的产品层出不穷,新产品在生产效能、操作简便、保养容易和运行可靠方面均有提高,但是塔机的技术并无根本性的改变。塔机的研究正向着组合式发展。所谓的组合式,就是以塔身结构为核心,按结构和功能特点,将塔身分解成若干部分,并依据系列化和通用化要求,遵循模数制原理再将各部分划分成若干模块。根据参数要求,选用适当模块分别组成具有不同技术性能特征的塔机,以满足施工的具体需求。推行组合式的塔机有助于加快塔机产吕开发进度,节省产品开发费用,并能更好的为客户服务。 塔机分为上回转塔机和下回转塔机两大类。其中前者的承载力要高于后者,在许多的施工现场我们所见到的就是上回转式上顶升加节接高的塔机。按能否移动又分为:走行式和固定式。固定式塔机塔身固定不转,安装在整块混凝土基础上,或装设在条形式X 形混凝土基础上。在房屋的施工中一般采用的是固定式的。 设备特点和安全装置 塔式起重机的动臂形式分水平式和压杆式两种。动臂为水平式时,载重小车沿水平动臂运行变幅,变幅运动平衡,其动臂较长,但动臂自重较大。动臂为压杆式时,变幅机构曳引动臂仰俯变幅,变幅运动不如水平式平稳,但其自重较小。 为了确保安全,塔式起重机具有良好的安全装置,如起重量、幅度、高度和载荷力矩等限制装置,以及行程限位开关、塔顶信号灯、测风仪、防风夹轨器、爬梯护身圈、走道护栏等。司机室要求舒适、操作方便、视野好和有完善的通讯设备。 塔式起重机的检验产要点 1) 检查金属结构情况特别是高强度的螺栓,它的连接表面应清除灰尘、油漆、没迹和锈蚀,并且使用力矩手或专用扳手,按装配技术要求拧紧。 2) 检查各机构传动系统,包括各工作传动机构的轴承间隙是否合适,齿轮啮合是不是良好及制动器是否灵敏。 3) 检查钢丝绳及滑轮的磨损情况,固定是否可靠。 4) 检查电气元件是否良好,名接触点的闭合程度,接续是否正确和可靠。 5) 检查行走轮与轨道接触是否良好,夹轨钳是否可靠。装设附着装置、内爬装置时,各连接螺栓及夹块是否牢固可靠。

段,即:20世纪50年代初到60年代初为起步阶段;60~70年代为专业化生产体系成长阶段;80~90年代为快速发展阶段。其中,液压工业于50年代初从机床行业生产仿苏的磨床、拉床、仿形车床等液压传动起步,液压元件由机床厂的液压车间生产,自产自用。进入60年代后,液压技术的应用从机床逐渐推广到农业机械和工程机械等领域,原来附属于主机厂的液压车间有的独立出来,成为液压件专业生产厂。到了60年代末、70年代初,随着生产机械化的发展,特别是在为第二汽车制造厂等提供高效、自动化设备的带动下,液压元件制造业出现了迅速发展的局面,一批中小企业也成为液压件专业制造厂。1968年中国液压元件年产量已接近20万件;1973年在机床、农机、工程机械等行业,生产液压件的专业厂已发展到100余家,年产量超过100万件,一个独立的液压件制造业已初步形成。这时,液压件产品已从仿苏产品发展为引进技术与自行设计相结合的产品,压力向中、高压发展,并开发了电液伺服阀及系统,液压应用领域进一步扩大。气动工业的起步比液压稍晚几年,到1967年开始建立气动元件专业厂,气动元件才作为商品生产和销售。含橡塑密封、机械密封和柔性石墨密封的密封件工业,50年代初从生产普通O型圈、油封等挤压橡塑密封和石棉密封制品起步,到60年代初,开始研制生产机械密封和柔性石墨密封等制品。70年代,在原燃化部、一机部、农机部所属系统内,一批专业生产厂相继成立,并正式形成行业,为密封件工业的发展成长奠定了基础。 进入80年代,在国家改革开放的方针指引下,随着机械工业的发展,基础件滞后于主机的矛盾日益突出,并引起各有关部门的重视。为此,原一机部于1982年组建了通用基础件工业局,将原有分散在机床、农业机械、工程机械等行业归口的液压、气动和密封件专业厂,统一划归通用基础件局管理,从而使该行业在规划、投资、引进技术和科研开发等方面得到基础件局的指导和支持。从此进入了快速发展期,先后引进了60余项国外先进技术,其中液压40余项、气动7项,经消化吸收和技术改造,现均已批量生产,并成为行业的主导产品。近年来,行业加大了技术改造力度,1991~1998年国家、地方和企业自筹资金总投入共约20多亿元,其中液压16亿多元。经过技术改造和技术攻关,一批主要企业技术水平进一步提高,工艺装备得到很大改善,为形成高起点、专业化、批量生产打下了良好基础。近几年,在国家多种所有制共同发展的方针指引下,不同所有制的中小企业迅猛崛起,呈现出

Analysis,Applications Of Cams INTRODUCTION It is absolutely essential that a design engineer know how and why parts fail so that reliable machines that require minimum maintenance can be designed.Sometimes a failure can be serious,such as when a tire blows out on an automobile traveling at high speed.On the other hand,a failure may be no more than a nuisance.An example is the loosening of the radiator hose in an automobile cooling system.The consequence of this latter failure is usually the loss of some radiator coolant,a condition that is readily detected and corrected.The type of load a part absorbs is just as significant as the magnitude.Generally speaking,dynamic loads with direction reversals cause greater difficulty than static loads,and therefore,fatigue strength must be considered.Another concern is whether the material is ductile or brittle.For example,brittle materials are considered to be unacceptable where fatigue is involved. Many people mistakingly interpret the word failure to mean the actual breakage of a part.However,a design engineer must consider a broader understanding of what appreciable deformation occurs.A ductile material,however will deform a large amount prior to rupture.Excessive deformation,without fracture,may cause a machine to fail because the deformed part interferes with a moving second part.Therefore,a part fails(even if it has not physically broken)whenever it no longer fulfills its required function.Sometimes failure may be due to abnormal friction or vibration between two mating parts.Failure also may be due to a phenomenon called creep,which is the plastic flow of a material under load at elevated temperatures.In addition,the actual shape of a part may be responsible for failure.For example,stress concentrations due to sudden changes in contour must be taken into account.Evaluation of stress considerations is especially important when there are dynamic loads with direction reversals and the material is not very ductile. In general,the design engineer must consider all possible modes of failure,which include the following. ——Stress ——Deformation ——Wear ——Corrosion ——Vibration ——Environmental damage ——Loosening of fastening devices

附录A Portal power China’s rapid economic growth in the past decade has resulted in a big increase in freight traffic through the country’s seaports . Old ports are being expanded and new ports built to handle the large growth in container and bulk cargo traffic all along the Chinese coastline. China’s port expansion programme has provided a strong boost to the domestic port equipment industry, which has enjoyed a strong increase in demand for port cranes of various types, including container cranes and portal cranes along with bulk cargo handling equipment. State-run China Harbour Engineering (group) Corporation Ltd, established under the ruling State Council, is China’s largest supplier of port cranes and bulk cargo handling equipment. The organization controls both Shanghai Zhenhua Port Machinery Co Ltd (ZPMC),the world’s largest manufacturer of quayside container cranes, and Shanghai Port Machinery Plant (SPMP), which specializes in the manufacturer of portal cranes and other cranes used in ports along with dry bulk cargo handling equipment. SPMP’s main market is China, although the company is looking to expand its overseas sales. Although less well known than its associate ZPMC, SPMP also operates large manufacturing facilities, and is due to move part of its production shortly to Changxing Island near Shanghai where ZPMC already operates a large container crane fabrication plant. Portal and other harbour cranes are SPMP’s major production item. During the past two years, the corporation has won contracts for 145 portal cranes from port authorities throughout China, both from new ports under construction and ports undergoing expansion. In recent years, SPMP has also supplied portal cranes to the United States, Iraq,and Myanmar.The port Rangoon of Myanmar in has purchased a 47m,40t portal crane while BIW of the United States has purchased three cranes-15t,150t, and 300t portal

液压系统液压传动和气压传动毕业论文中英文资料对照外文翻译文献综述

中英文资料对照外文翻译文献综述 液压系统 液压传动和气压传动称为流体传动,是根据17世纪帕斯卡提出的液体静压力传动原理而发展起来的一门新兴技术,1795年英国约瑟夫?布拉曼(Joseph Braman,1749-1814),在伦敦用水作为工作介质,以水压机的形式将其应用于工业上,诞生了世界上第一台水压机。1905年将工作介质水改为油,又进一步得到改善。 第一次世界大战(1914-1918)后液压传动广泛应用,特别是1920年以后,发展更为迅速。液压元件大约在 19 世纪末 20 世纪初的20年间,才开始进入正规的工业生产阶段。1925 年维克斯(F.Vikers)发明了压力平衡式叶片泵,为近代液压元件工业或液压传动的逐步建立奠定了基础。20 世纪初康斯坦丁?尼斯克(G?Constantimsco)对能量波动传递所进行的理论及实际研究;1910年对液力传动(液力联轴节、液力变矩器等)方面的贡献,使这两方面领域得到了发展。 第二次世界大战(1941-1945)期间,在美国机床中有30%应用了液压传动。应该指出,日本液压传动的发展较欧美等国家晚了近 20 多年。在 1955 年前后 , 日本迅速发展液压传动,1956 年成立了“液压工业会”。近20~30 年间,日本液压传动发展之快,居世界领先地位。 液压传动有许多突出的优点,因此它的应用非常广泛,如一般工业用的塑料加工机械、压力机械、机床等;行走机械中的工程机械、建筑机械、农业机械、汽车等;钢铁工业用的冶金机械、提升装置、轧辊调整装置等;土木水利工程用的防洪闸门及堤坝装置、河床升降装置、桥梁操纵机构等;发电厂涡轮机调速装置、核发电厂等等;船舶用的甲板起重机械(绞车)、船头门、舱壁阀、船尾推进器等;特殊技术用的巨型天线控制装置、测量浮标、升降旋转舞台等;军事工业用的火炮操纵装置、船舶减摇装置、飞行器仿真、飞机起落架的收放装置和方向舵控制装置等。 一个完整的液压系统由五个部分组成,即动力元件、执行元件、控制元件、辅助元

外文文献原文: Friction , Lubrication of Bearing In many of the problem thus far , the student has been asked to disregard or neglect friction . Actually , friction is present to some degree whenever two parts are in contact and move on each other. The term friction refers to the resistance of two or more parts to movement. Friction is harmful or valuable depending upon where it occurs. friction is necessary for fastening devices such as screws and rivets which depend upon friction to hold the fastener and the parts together. Belt drivers, brakes, and tires are additional applications where friction is necessary. The friction of moving parts in a machine is harmful because it reduces the mechanical advantage of the device. The heat produced by friction is lost energy because no work takes place. Also , greater power is required to overcome the increased friction. Heat is destructive in that it causes expansion. Expansion may cause a bearing or sliding surface to fit tighter. If a great enough pressure builds up because made from low temperature materials may melt. There are three types of friction which must be overcome in moving parts: (1)starting, (2)sliding, and(3)rolling. Starting friction is the friction between two solids that tend to resist movement. When two parts are at a state of rest, the surface irregularities of both parts tend to interlock and form a wedging action. To produce motion in these parts, the wedge-shaped peaks and valleys of the stationary surfaces must be made to slide out and over each other. The rougher the two surfaces, the greater is starting friction resulting from their movement . Since there is usually no fixed pattern between the peaks and valleys of two mating parts, the irregularities do not interlock once the parts are in motion but slide over each other. The friction of the two surfaces is known as sliding friction. As shown in figure ,starting friction is always greater than sliding friction . Rolling friction occurs when roller devces are subjected to tremendous stress which cause the parts to change shape or deform. Under these conditions, the material in front of a roller tends to pile up and forces the object to roll slightly uphill. This changing of shape , known as deformation, causes a movement of molecules. As a result ,heat is produced from the added energy required to keep the parts turning and overcome friction. The friction caused by the wedging action of surface irregularities can be overcome
