外国文学史(上)的诗歌

外国文学史(上)的诗歌

(田晓菲 译)
没有听她说一个字
坦白地说,我宁愿死去 当她离开,她久久地 哭泣;她对我说 “这次离别,一定得 忍受,萨福。我去,并非自愿” 我说:“去吧,快快活活的 但是要记住(你清楚地知道) 离开你的人戴着爱的镣铐 和所有那些紫罗兰色的头饰 围绕在你年轻的头上的 一串玫瑰花蕾、莳萝和番红花 芬芳的没药撒在你的 头上和柔软的垫子上,少女们 和她们喜爱的人们在一起 如果没有我们的声音 就没有合唱,如果 没有歌曲,就没有开花的树林。
萨福诗 残诗三十一首(frg. 31)《给所爱》
• • • • • • • • • • • • 在我看来,他的享受好似天神 无论他是何人,坐在 你的对面,听你娓娓而谈 你言语温柔,笑声甜蜜 啊那是让我的心飘摇不定 当我看到你,哪怕只有 一刹那,我已经 不能言语 舌头断裂,血管里奔流着 细小的火焰 黑暗蒙住了我的双眼, 耳鼓狂敲 SAPPHO AND PHAON 冷汗涔涔而下 我颤栗,脸色比春草惨绿 我虽生犹死,至少在我看来—— 死亡正在步步紧逼 但我必须忍受 因为□ □ □ 既然贫无所有□ □ □
一百一十六首
我不承认两颗真心相恋 会遭遇阻挠:爱不算是爱, 如果发现情形改变就跟着改 变, 或看到对方变心就打算走开。 啊,不!爱是永远坚定的明 灯, 面对着风暴而永不摇荡; 爱是指引飘流船只的明星, 其高度可测,其奥秘不可衡 量。 爱不是“时间”的玩物,虽 然朱唇粉颊 逃不脱他弯弯镰刀的割芟 ; 爱不跟随流转的韶光而起变 化, 爱抵抗“时间”到世界末日 的尽端。 假如这话不对,而且引我 为证, 我算是没写过诗,没人有 过爱情。 梁实秋译
山部赤人《望不尽山歌一首并短歌》 (约724-736,不尽山即富士山)
天地初分时, 富士骏岭悬。 圣洁神瑞气, 高临骏河湾。 仰望灵峰立广宇; 骄阳为其隐光影, 皓月清辉敛玉颜, 白云不行伫峰顶, 瑞雪不时飘九天。 后世永称颂, 崇高富士山。 反歌

英语中不定式(todo)的6种成分和2种独立用法

英语中不定式(todo)的6种成分和2种独立用法

英语中不定式(todo)的6种成分和2种独立用法非谓语是英语学习的重点也是难点,很多同学对这个语法知识一直是处于比较懵的状态。

其实只要掌握非谓语所充当成分的用法就可以运用自如了。

非谓语,顾名思义就是不做谓语的动词的变化形式,即to do ,doing,done。

除了谓语,句子成分中还有主语、宾语、表语、宾语补足语、定语和状语。

下面看看不定式(to do)充当这6种成分的用法:一、不定式作主语1.To see is to believe. (这种情况不常用)2. It is important to learn English well.It 是形式主语,真正的主语是 to learn English well. 这种用法是常用的而且是考点!考点!考点!二、不定式作表语:常说明主语的内容、性质和特征或表动作将要发生。

1. My job is to keep the children safe.2.My task is to type the article.三、不定式做宾语1.He prefers to eat white bread and rice.2.He wants to play football.3.动词feel, find, make, think等后面,可以用it作形式宾语代替真正的宾语——动词不定式,句子结构是...feel / find / make / ... it+adj. / n.+to do...。

如:I find it difficult to remember everything.常接动词不定式作宾语的动词有:(需要记住)agree, afford, appear, ask, attempt;care, choose, claim;dare,decide,demand,deserve,determine;expect, fail, get, guarantee;hate, hesitate, hope, hurry;intend, learn, manage, offer,plan, prepare, pretend, promise;refuse, seem, tend, threaten;want, wish 等四、不定式做宾语补足语1.I'd invite her to have dinner at my house.2 . We should allow the children to choose their own clothes.Note 1: 带to的动词不定式作宾语补足语的动词主要有:要求允许提议(ask, allow, advise),期望邀请鼓励(expect, invite, encourage),教导告诉想要(teach, tell, want),等待希望愿意(wait for, wish, would like / love)。

只要顺应自然,人人皆可长寿Comply with the Nature, Share a LongLifespan国医大师李振华认为,一个人的寿命与饮食有极大的关系,吃太多油腻的食物,会导致许多疾病,寿命自然不会长久,因此,他建议大家多吃素食,这对于养生保健有极大的帮助。

Li Zhenhua, master of traditional Chinese medicine, considers that people’s lifespan concerns with their diet greatly, say taking too much greasy food will raise high risk of suffering diseases which doesn’t ensure you longevity. Therefore, he suggests all intake more vegetarian food which will benefit a lot to health preservation and promotion.我们提倡素食,并不是要大家放弃所有动物性食品,放弃油脂,每天用蔬菜和水果代替所有的食品,而是要在食物多样化的前提下,控制脂肪的摄入量;主食以谷类为主;多吃蔬菜水果;经常吃奶类、豆类和适量的鱼、禽、疍、瘦肉。

只有这样,才能保证饮食中的蛋白质、脂肪等营养素满足人体基本的需要。

否则,营养不均衡,对健康十分不利。

尤其是对孩子,单纯、过分的素食甚至可能对发育产生负面影响。

Advocating for vegetarian food doesn’t require everyone to quit having all animal food, oil and fat, taking place all food with vegetable and fruit, but on the precondition of food variety, controlling fat intake; having cereal food as staple food; taking more vegetable and fruit; frequently having milk, beans and proper amount fish, chicken, egg and meat. Only by doing these, it can guarantee protein, fat and other nutrition in food to satisfy basic needs of human body. Otherwise, uneven nutrition will harm your health, especially to children, pure and excessive intaking vegetarian food could have negative effect to their growth.注重形象,树立个人品牌Pay Attention to Image, Set upPersonal Brand人在职场,个人的形象很重要,因为我们的个人形象,代表着我们所在企业形象、企业的产品形象、企业的服务形象。

This course will give you an introduction to SKF bearings and consists of three sections: Functions and parts,Applications and bearing types,and Designations.Module 1: Functions and partsWhy bearings?Bearings are an essential component of almost all machinery. They transmit loads between, support, guide and locate, machine elements that are required to move relative to each other with a minimum of friction, e.g.a rotating or oscillating shaft, pivot or wheel.Friction: Page 1Friction counteracts the movement between two surfaces. It is essential for the success of many operations, such as a car tyre gripping a road. In most machines however, friction is undesirable since it causes power loss, heat generation, wear and noise. SKF bearings help reduce friction.Friction: Page 2The earliest bearings were mostly made of wood and consisted of a shaft rotating in a hole in a housing, or a wheel rotating on a stationary shaft. Because the components were sliding over each other, friction was relatively high and wear rather rapid.This type of bearing is called a plain bearing and, made of modern materials, is still used in some applications today where speeds and loads are relatively low.Friction: Page 3The introduction of rolling elements between the shaft and the housing greatly reduces friction.Friction: Page 4Today, typical SKF rolling bearings combine maximum load capacity with minimum friction, using hardened steel or ceramic rolling elements, hardened steel inner and outer rings and a cage to guide and separate the rolling elements.Loads: Page 1A bearing can be under radial load, perpendicular to the shaft, or under axial load, acting in the direction along the shaft, or a combination of both radial and axial load, a combined load.Loads: Page 2Large bearings support heavier loads than small bearings can support, and roller bearings support heavier loads than ball bearings can support. Raceway contactThe basic difference between ball bearings and roller bearings is in the contacts between the rolling elements and the raceways. Balls have point contact; rollers have linear contact with relatively larger area.Bearing partsA typical rolling bearing consists of an inner ring, an outer ring and rolling elements contained by a cage. The most common type of rolling bearing is the deep groove ball bearing. These bearings can, as shown here, be supplied with integral seals to retain the lubricant and resist the ingress of contamination.Selection factorsThere are many factors, which will affect the choice of a bearing. These are: Available space, load, required service life, misalignment, speed, stiffness, axial displacement and clearance.Selection factors: SpaceSpace can be an important factor in bearing selection. Where radial space is limited a bearing with small diameter rolling elements, such as a needle roller bearing, may be needed.Selection factors: LoadWhen selecting a bearing, it is important to consider the direction of the load, and the amount of load the bearing will have to carry. A bearing can be under radial load, axial load, or a combination of both.Selection factors: Required service lifeThe life of a bearing can be expressed in terms of: the number of revolutions before failure, the number of operating hours before failure, or the distance covered (for cars and trucks). A bearing is considered to have failed when it shows the first sign of fatigue in a rolling element or raceway, or damage to other parts such as the cage or the seals. Service life is the real life that an individual bearing achieves in a particular application before it has to be replaced. It depends on a variety of influencing factors, including lubrication, the degree of contamination, misalignment, proper installation, and environmental conditions.Because service life cannot be calculated or predicted, bearings are selected using calculated rating life. SKF rating life L10m, a reference value calculated according to statistical methods, using modification factors for lubrication conditions and degree of contamination, and applying the same concept of a fatigue load limit as used in ISO 281, to estimate the life, with 90% reliability, that a sufficiently large population of apparently identical bearings might achieve when all are operating in an identical application.Selection factors: MisalignmentWhere a bearing is likely to be subject to angular misalignment, for example the shaft might bend due to operating loads, appropriate bearings need to be selected. Self-aligning bearings can accept a degree of operational misalignment and can also compensate for limited initial alignment errors in mounting.Selection factors: SpeedThe maximum speed that a bearing can be run in an application is limited by the maximum operating temperature for the materials used in its manufacture, or the lubricant. For high-speed applications minimum possible friction is important, so ball bearings are generally used. Selection factors: StiffnessElastic deformation occurs under load. Usually this deformation is very small and can be ignored. However, in some applications, stiffness is an important factor. Roller bearings have higher stiffness than ball bearings due to the larger area of the line contact.Selection factors: Axial displacementSome applications require bearings that allow the shaft to move axially relative to the bearing. This is called axial displacement. Most often, a shaft is supported by a locating bearing and a non-locating bearing. The locating bearing does not allow axial displacement and keeps the shaft in position. The non-locating bearing supports the shaft and allows displacement to prevent the bearings from being stressed. Cylindrical and CARB toroidalroller bearings can accommodate a limited degree of axial internal displacement.Selection factors: ClearanceThe amount of initial internal radial clearance required in a bearing depends mainly on the fits and temperature gradient between the inner and outer rings of the bearing in the particular application. Operational internal radial clearance is almost always less than initial internal clearance. SKF manufactures bearings with the following ranges of radial internal clearances:•C1 radial internal clearance less than C2•C2 radial internal clearance less than Normal•-- Normal radial internal clearance•C3 radial internal clearance greater than Normal•C4 radial internal clearance greater than C3SummaryIn this lesson, you have learnt about the functions of a bearing. These are: reducing friction, transmitting loads, locating and guiding moving parts. You have also been introduced to the different parts of a bearing: outer and inner rings, rolling elements, cage, and seals and their respective functionalities.Finally, you have also explored the different selection factors, which will affect your choice of bearing: available space, load, required service life, misalignment, speed, stiffness, axial displacement and clearance.Module 2: ApplicationsIntroductionIn this section you will be introduced to the most common bearing types offered by SKF.Electrical motors can be found almost anywhere there is mechanical movement.Motor: Page 2In this drawing you can see that the shaft is supported by two different bearings.Motor: Page 3Cylindrical roller bearings are simply bearings with cylindrical rollers. They can usually accommodate heavy radial loads and can operate at relatively high speeds.Motor: Page 4It is now time to choose the right side bearing.Motor: Page 5Deep groove ball bearings have deep uninterrupted raceways and close osculation between balls and raceways. This enables them to take axial loads in both directions.Pump: Page 1A pump is a device for lifting, transferring or moving fluids by suction or pressure from one position to another. This picture shows a medium-duty process pump, which is often used in refineries.Pump: Page 2In this drawing you can see that the shaft, which is running the impeller, is supported by one deep groove ball bearing to the right, and another bearing or bearings to the left.Single row angular contact ball bearings are widely used in medium and heavy-duty centrifugal pumps. They have raceways arranged at an angle to the bearing axis.Pump: Page 4Single row angular contact ball bearings can only take axial load in one direction. Therefore they are nearly always mounted as pairs in back to back or face to face arrangement at either end of a shaft, or as shown here, universally matchable bearings mounted immediately adjacent to each other.Fan: Page 1This is an industrial fan, in which SKF bearings are commonly used. Industrial fans can either be designed for light loads and high speeds, or for heavy loads and moderate speeds.Fan: Page2A fan is designed with two bearings along its shaft, placed between the fan and the motor. Both bearings carry radial loads and the bearing closest to the fan (on the left hand side here) also needs to be a locating bearing, keeping the shaft and the fan in a fixed position.Fan: Page 3Spherical roller bearings have two rows of rollers with a common raceway in the outer ring. The two inner ring raceways are inclined at an angle to the bearing axis.Fan: Page 4Returning to the fan application again, you now know which bearing is suitable as the locating bearing and here you have to make a guess concerning the non-locating bearing.CARB [ka:b] is a single row toroidal roller bearing with long, slightly crowned, rollers and concave raceways in both the inner and outer rings. Fan: Page 6The complete application looks like this with one spherical roller bearing and one CARB toroidal roller bearing.Separator: Page 1Alfa Laval, a Swedish company, has developed a range of machines specifically designed for rigorous oil processing duties. An example of this would be separators.Separator: Page 2The separation process creates imbalance due to the mud, which is distributed unevenly inside the separator and this makes the spindle bend. Separator: Page 3Self-aligning ball bearings have two rows of balls and a common concave sphered raceway in the outer ring. This makes the bearing insensitive to angular misalignments of the shaft relative to the housing. Self-aligning ball bearings accommodate high speeds due to the point contact between balls and raceways.Refiner: Page 1SKF bearings can be used in refiners in the production of mechanical pulp and other high-yield pulps.Refiner: Page 2In the process wood chips are ground at high mechanical pressure between a stationary disc and a rotating disc, which is powered by an electrical motor. The shaft between the motor and the grinding discs is supported by three bearings.Refiner: Page 3The high production capacity of the refiners is directly related to the demands on the bearing arrangement. The bearings have to provide high stability, operate at high speed, carry high thrust loads and handle deflections of the shaft.Refiner: Page 4The spherical roller thrust bearing incorporates a large number of asymmetrical, spherical rollers and has specially designed raceways. The load is transmitted from one raceway to the other at an angle to the bearing axis and the bearing can carry heavy axial load in one direction and some simultaneously applied radial load as well.Refiner: Page 5This is how the spherical roller thrust bearings are situated in the refiner application.Screw conveyor: Page 1Machines used in the agricultural industry often require bearings that can easily be changed and that can handle misalignments.Screw conveyor: Page 2This is a drawing of a screw conveyor attached to an agricultural machine. The bearings are the only contact between the screw conveyor and the machine.Screw conveyor: Page 3A Y-bearing unit consists of two parts: a housing and a bearing. The bearing is based on the deep groove ball bearing and can carry light radial and axial loads. It has a convex-sphered outside diameter, which allows the bearing to take up misalignment between the shaft and housing at the assembly stage. They are available with a wide range of highly effective,integral seals and a range of different methods for easy mounting to the shaft.Screw conveyor: Page 4This is what the Y-bearing unit looks like in the screw conveyor.Front wheel: Page 1SKF bearings are used in front wheels of commercial vehicles. These applications require bearings that can handle very heavy loads.Front wheel: Page 2This drawing shows how a truck front wheel arrangement is designed and where its bearings are situated. The bearings must carry a large part of the weight of the vehicle and the induced forces when driving, which means that they have to handle heavy loads in both radial and axial directions.Front wheel: Page 3Tapered roller bearings have tapered rollers running in tapered inner and outer ring raceways. This design makes them suitable for handling heavy combined loads.A tapered roller bearing can only carry axial loads in one direction and, for this reason, they are generally fitted in pairs.Front wheel: Page 4See how the tapered roller bearings are mounted in the front wheel of a commercial vehicle.SummaryIn this lesson, you have studied the most common SKF bearing types. Now click on each bearing picture to repeat the most important characteristics of each type. If you want to read more about SKF bearings, enter the SKF Interactive Engineering Catalogue on line at .Module 3: DesignationsIntroductionSKF bearing designations describe a bearing’s or component’s type, design, and variants. The designation can be found both on the box and on the bearing itself.Basic designations: Page 1A bearing designation for metric size bearings can either consist of a basic designation alone or a basic designation plus one or more supplementary designations, called prefixes and suffixes.The basic designation identifies the product type and size, while the supplementary designations identify design, special variants and bearing components.Basic designations: Page 2Each SKF bearing of standard metric design is given a basic designation, which normally consists of three, four or five figures.Basic designations: Page 3For example, the basic designation 22206 denotes a spherical roller bearing with the width series 2, diameter series 2 and a bore diameter of 30 mm.Supplementary designations: Page 1The supplementary designations consist of both prefixes and suffixes. Supplementary designations: Page 2Prefixes are used to identify component parts of a bearing and are usually followed by the designation of the complete bearing.Supplementary designations: Page 3Suffixes are used to identify designs, which differ in some way from the original design. The suffixes are divided into four main groups: Internal design, external design, cage design and variants, all of which are added to the basic designation in this order.End of course testNow it’s time to see what you learned.If you pass the test on-line then you’ll be able to print your course completion certificate.。

由败诉方承担律师费的中英文条款

由败诉方承担律师费的中英文条款

由败诉方承担律师费的中英文条款The concept of the losing party bearing the attorney's fees is a contentious issue in the legal landscape. This clause, often incorporated into contracts and legal agreements, has been the subject of much debate and discussion. In this essay, we will delve into the nuances of this provision, exploring its implications and examining its application in both the Chinese and English legal systems.Firstly, it is essential to understand the rationale behind the losing party bearing the attorney's fees clause. The primary objective of this provision is to discourage frivolous or groundless litigation and to incentivize parties to resolve disputes in a more efficient and cost-effective manner. By shifting the financial burden of legal representation to the party that is ultimately deemed unsuccessful, the clause aims to deter individuals or organizations from pursuing claims that lack merit or are primarily intended to inflict financial harm on the opposing side.In the Chinese legal system, the principle of the losing party bearingthe attorney's fees is codified in the Civil Procedure Law of the People's Republic of China. Article 84 of this law stipulates that the losing party shall be responsible for the reasonable expenses incurred by the winning party, including legal fees. This provision is designed to promote fairness and discourage the abuse of the legal system. Furthermore, the Chinese courts have the discretion to adjust the amount of attorney's fees to be borne by the losing party based on the specific circumstances of the case, such as the complexity of the legal issues and the overall conduct of the parties.Conversely, in the English legal system, the approach to attorney's fees is somewhat different. The general principle in England and Wales is that the "costs follow the event," meaning that the unsuccessful party is typically ordered to pay the legal costs of the prevailing party. This principle is codified in the Civil Procedure Rules, which govern the conduct of civil litigation in the English courts. However, the courts have the discretion to depart from this general rule and apportion the costs in a manner that they deem appropriate, taking into account factors such as the conduct of the parties, the reasonableness of their respective positions, and the overall proportionality of the costs incurred.It is worth noting that the application of the losing party bearing the attorney's fees clause can have significant implications for the parties involved. For the winning party, this provision can provide a sense offinancial security and a deterrent against frivolous claims, as they are assured of recovering their legal expenses. Conversely, for the losing party, the financial burden of bearing the attorney's fees can be a significant and potentially crippling consequence, which may deter individuals or organizations from pursuing claims, even if they believe they have a strong case.Moreover, the implementation of this clause can have broader societal implications. By discouraging the abuse of the legal system and promoting more efficient dispute resolution, the losing party bearing the attorney's fees clause can contribute to the overall effectiveness and integrity of the judicial process. This, in turn, can foster greater public confidence in the legal system and promote a culture of responsible and ethical litigation practices.In conclusion, the clause of the losing party bearing the attorney's fees is a complex and multifaceted issue that has been approached differently in the Chinese and English legal systems. While the underlying rationale of promoting fairness and discouraging frivolous litigation is shared, the specific implementation and application of this principle can vary. As with any legal concept, it is essential to consider the nuances, implications, and broader societal impact of this provision to ensure that it is applied in a manner that upholds the principles of justice and the rule of law.。

信用证英语:against

信用证英语:against

在国际贸易中,进⼝⼈和出⼝⼈都不愿意把货或钱先交给对⽅,为了解决这⼀⽭盾,避免风险,就出现了信⽤证付款的信⽤⽅式,即信⽤证(Letter of Credit,简称L/C )。

信⽤证⽀付⽅式是⽬前国际贸易中最主要的付款⽅式,我国⽬前近百分之七⼗的进出⼝货物都是靠信⽤证结汇完成的。

在对信⽤证的实际操作中,业务员由于专业及英语⽔平层次不⼀,对信⽤证特别条款理解不深或理解错误,给企业或所在单位造成不应有的损失的事情时有发⽣。

信⽤证的内容⼀般来说较为复杂,长句⼦多,涉及到⾦融、保险、商检、报运、银⾏等多项专业知识。

信⽤证的审核既需要英语⽔平,还需要多年积累的经验。

单证审核也是⼀项专门技术。

下⾯我们就对信⽤证条款中的⼀些关键英⽂词语做必要的翻译和分析,供⼤家参考。

今天我们先来看看against。

我们常见的against 是介词,通常意为“反对”( indicating opposition) ,例如:Public opinion was against the Bill. 舆论反对此法案。

The resolution was adopted by a vote of 30 in favour to 4 against it. 决议以30 票赞成、4 票反对获得通过。

另外还有“⽤…… 交换,⽤…… 兑付”之意。

如:“the rates against U. S. dollars”中的against 就是指美元兑换率。

但在信⽤证中常出现的against 这个词及词义却另有所指,⼀般词典⽆其释义及相关⽤法。

注意以下两个出现在信⽤证句中的against 之意,其意思是凭…… ”、“以…… ”(“take as the basis” or “by”),⽽不是“以…… 为背景”、“反对”、“对照”、“兑换”或其他什么意思。

1. This credit valid until September 17, 2001 in Switzerland for payment available against the presentation of following documents… 本信⽤证在2001年9⽉17⽇在瑞⼟到期前,凭提交以下单据付款……2. Documents bearing discrepancies must not be negotiated against guarantee and reserve. 含有不符之处的单据凭保函或在保留下不能议付。

2.1. 4 原因分析
机车概论
轴承在正常的条件下使用, 套圈和滚动体的滚动面因不停地重复地受到压力,
亦会发生材料疲劳, 以致造成剥离而无法使用。滚动轴承一旦承受负荷, 其 滚动体与套圈接触面就会发生局部永久变形。该变形量随负荷增大而变大, 若超过某种限度, 则会影响正常运转。轴承烧伤、磨损、裂纹缺口、卡死、 生锈等都有可能使轴承无法使用,但这应称为轴承故障, 须与轴承寿命区分开 。轴承选型不当, 安装欠妥, 润滑不良及密封不好等都是发生轴承故障的原 因, 排除这些原因便可避免轴承发生故障。

Sleeve Bearing Lubrication Mike JohnsonPlain BearingsThere are two broad types of bearings used in machinery today: plain and rolling element bearings. This article targets the special lubrication requirements of plain bearings, also known as sleeve bearings and journal bearings.The plain bearing consists of a shaft, also called a journal, and a supporting component, which may be a shell around the shaft called a sleeve, a half shell that the shaft fits into, two half shells (top and bottom parts) or a multipart shell.See Figure1Plain bearings are used for high radial loads (perpendicular to the axis of the shaft) and low to high speeds. Typical applications include turbines, large milling systems, engine cranks, compressors, gearboxes, shaft bearing supports, etc.Every journal bearing has some common design characteristics as shown inFigure 2.The components that are separated by the oil film in a plain bearing are the bearing liner and the shaft. The shaft is composed of high-quality, wear-resistant, structurally strong steel. The bearing liner may be made of a single layer or multiple layers, depending on the design features of the equipmentLubrication RegimeUnder normal operating conditions, the lubrication regime will be a hydrodynamic full-fluid film. A hydrodynamic film occurs when there is sufficient lubricant between the lubricated surfaces at the point of loading to form a fluid wedge that separates the sliding surfaces. In this state, the lubricated components do not touch each another, reducing friction and wear.This condition is represented by the equation ZN/P, where Z = viscosity, N = speed (rpm) and P = load. This equation is represented by Figure 4.The curve on this graph is called the Stribeck Curve. It is the classical representation of the relationship between speed, load and friction.Mixed film conditions occur when a loss of the film resulting in momentary contact between the two surfaces is apparent. This can occur in response to momentary variations in loading, called shock-loading, that can collapse the film, resulting in physical contact of opposing asperities.Another condition that can occur is boundary film lubrication. This is when the film that separates the surfaces undergoes significant loss resulting in a high load of metal-to-metal contact. This happens any time the relative motion of component surfaces are slow and no oil film is formed.Lubrication Needs of a Plain BearingOperating under proper speed, surface area, viscosity and oil volume, a plain bearing can support very heavy loads. The balance between these conditions is important. If the load or the speed changes, the lubricant viscosity must be adjusted to compensate for the change. There is no simple formula that is used to calculate the viscosity requirements for oil lubricated plain bearings, but the ZN/P formula demonstrates the results of complex calculations used to arrive at the proper clearance.Criteria to consider once you have identified the proper viscosity grade include oxidation stability, corrosion inhibition, wear protection, water and air separation properties, etc. Because plain bearings can be used in a variety of applications, there is no single set of criteria that should be used. Selection depends on the equipment design and operating conditions.Plain bearings are normally oil lubricated, but may be lubricated with grease for slow-speed equipment, particularly if they are subject to frequent starts and stops or the bearings may be physically difficult to reach.The type and amount of grease depends on continuous replenishment of the body of grease that is held within the dynamic clearances (empty spaces while the bearing is turning) in order to maintain effective lubricant condition and hydrodynamic lift. Equipment with poor sealing characteristics may require a heavier body of lubricant and more frequent replenishment cycles.Under manual (intermittent) relubrication, the volume and the frequency are influenced by operating conditions, grease quality and available time for the task. Grease selection begins with consideration of the oil to be used. Heavy oils are used to formulate greases used to manually lubricate plain bearings in high-duty service.After the proper viscosity oil has been selected, then the soap thickener, oxidation and rust characteristics, worked consistency properties, pumpability (for automatic systems) and load-bearing (EP/AW) properties are considered. For long intervals and very heavy loading, solid additives such as molybdenum disulfide or graphite may be incorporated. The solid additives would serve to mechanically prevent metal contact in mixed film and boundary lubrication conditions.The grease should be pumped into the bearing in front of the load zone and at the location of the grease grooves used for lubricant distribution (Figures 5 and 6).Figure 6Wear and Failure Modes in Plain BearingsThere are several factors that can wipe or damage a plain bearing surface. Abrasive wear is one of the most common. If the wear is caused by a hard particle rubbing between the lubricated surfaces, it is called three-body wear. Wear caused by an asperity on one surface cutting the other surface is called two-body abrasion.Wear can also result from insufficient volume of lubricant (starvation leading to boundary conditions), overheated lubricant (viscosity at operating temperature cannot support the load causing frictional heat and additional oil thinning), rough surfaces (asperities on the journal cause rubbing), imbalance (improper loading of the support element causing shock loading), journal eccentricity (egg-shaped journal causing rubbing on the high spots), and metal fatigue from improper metallurgy. Journal bearing wear can be effectively monitored by oil and ferrographic analysis.See Figure7The telltale indicators that may point to high wear conditions include high metallic particle counts (two levels above norm), darkened metal surfaces, blued metal surfaces and wear metals formed into spirals or platelets. As oils age and become contaminated with moisture or acidic oxidation compounds, we can see evidence of corrosion and metallic oxidation on stationary surfaces in the reservoir.。
