2 Lubrication润滑Although one of the main purposes of lubrication is to reduce friction, any substance –liquid, solid, or gaseous—capable of controlling friction and wear between sliding surfaces(滑动表面) can be classed as (定义为)a lubricant.Varieties of lubricationUnlubricated(无润滑) sliding. Metals that have been carefully treated to remove all foreign materials(异物) seize and weld to one another when slid together. In the absence of(如果没有) such a high degree of cleanliness, adsorbed(吸附的) gases, water vapor, oxides(氧化物), and contaminants (杂质)reduce friction and the tendency to seize but usually result in severe wear, this is called “unlubricated” or dry sliding (干滑动).Fluid-film(流体膜) lubrication.Interposing a fluid film that completely separates the sliding surfaces results in fluid-film lubrication. The fluid may be introduced intentionally as the oil in the main bearing(主轴承) of an automobile, or unintentionally, as in the case of water between a smooth rubber tire(橡胶轮胎) and a wet pavement(路面). Although the fluid is usually a liquid such as oil, water, and a wide range of other materials, it may also be a gas. The gas most commonly employed is air.To keep the parts separated, it is necessary that the pressure within the lubrication film balance(与…保持平衡) the load on the sliding surfaces. If the lubricating film’s pressure is supplied by an external source, the system is said to be lubricated hydro-statically(静压地). If the pressure between the surfaces is generated as a result of the shape and motion of the surfaces themselves,however, the system is hydro-dynamically(动压地) lubricated. This second type of lubrication depends upon the viscous properties(粘度特性) of the lubricant.Boundary lubrication. A condition that lies between unlubricated sliding and fluid –film lubrication is referred to as(称作) boundary lubrication, also defined as that condition of lubrication in which the friction between surfaces is determined by the properties of the surfaces and properties of the lubricant other than viscosity(粘度). Boundary lubrication encompasses(包含) a significant portion of lubrication phenomena(润滑现象) and commonly occurs during the starting and stopping of machines.Solid lubrication. Solids such as graphite(石墨) and molybdenum disulfide(二硫化钼) are widely used when normal lubricants do not possess sufficient resistance to load or temperature extremes. But lubricants need not take only such familiar forms as fats, powders, and gases; even some metals commonly serve as sliding surfaces in some sophisticated(精密的) machines.Functions of lubricantsAlthough a lubricant primarily controls frictions and wear, it can and ordinarily does perform numerous other functions, which vary with the application and usually are interrelated.Friction control. The amount and character of the lubricant made available to sliding surfaces have a profound effect upon the friction that is encountered. For example, disregarding such related factors as heat and wear but considering friction alone between two oil-film lubricated surfaces, the friction can be 200 times less than that between the same surfaces with no lubricant. Under fluid-film conditions, friction is directly proportional to(与…成正比) the viscosity of the fluid. Some lubricant, such as petroleum derivatives(衍生物), is available in a great range of viscosities(具有较大的粘度范围) and thus can be satisfy a broad spectrum of functional requirements. Under boundary lubrication conditions, the effect of viscosity on friction becomes less significant than the chemical nature(化学性质) of the lubricant.Wear control. Wear occurs on lubricated surfaces by abrasion(磨蚀), corrosion, and solid –to-solid contact. Proper lubricants will help combat(克服) each type. They reduce abrasive and solid-to-solid contact wear by providing a film that increases the distance between the sliding surfaces, thereby lessening the damage by abrasive contaminants and surfaces asperities(粗糙不平).Temperature control.Lubricants assist in controlling temperature by reducing friction and carrying off(带走) the heat that is generated. Effectiveness(效果) depends upon the amount of lubricant supplied, the ambient temperature, and the provision for external cooling. To a lesser extent(在小范围内), the type of lubricant also affects surface temperature.Corrosion control.The role of lubricants in controlling corrosion of the surfaces themselves is twofold(双重的). When machinery is idle(闲置), the lubricants act as a preservative(防锈剂). When machinery is in use, the lubricant controls corrosion by coating lubricated parts with a protective film that may contain additives(添加剂) to neutralize(中和) corrosive materials. The ability of a lubricant to control corrosion is directly related to the thickness of the lubricant film remaining on the metal surfaces and the chemical composition(化学成分)of the lubricant.Other functionsLubricants are frequently used for purposes other than the reduction of friction. Some of these applications are described below.Power transmission. Lubricants are widely employed as hydraulic fluid(液压流体) in fluid transmission devices.Insulation.In specialized applications such as transformers and switchgear, lubricants with high dielectric constants(介电常数) act as electrical insulators. For maximum insulating properties, a lubricant must be kept free of(不能含有) contaminants and water.Shock dampening.Lubricants act as shock-dampening fluids in energy-transferring devices such as shock absorbers(减震器) and around machine parts such as gears that are subjected to high intermittent(间歇性的) loads.Sealing. Lubricating grease(润滑脂、黄油) frequently performs the special function of forming a seal(密封圈) to retain lubricants or to exclude contaminants.。

Some of the terms used in mechanics are defined below. Force Our earliest ideas concerning forces arose because of our desire to push, lift, or pull various objects. So force is the action of one body on another. Our intuitive concept of force includes such ideas as place of application , direction, and magnitude, and these are called the characteristics of a force.

Spur GearsGears , defined as toothed members transmitting rotary motion from one shaft to another , are among the oldest devices and inventions of man . In about 2600 B.C. , the Chinese are known to have used a chariot incorporating a complex series of gears . Aristotle , in the fourth century B.C. , wrote of gears as if they were commonplace . In the fifteenth century A.D. , Leonardo da Vinci designed a multitude of devices incorporating many kinds of gears .齿轮,在最古老的设备和发明人中,被定义为通过轮齿将旋转运动从一根轴传递到另一根轴,大约在公元前2600年,中国人就知道用战车组成一系列复杂的齿轮系。

西元前四世纪,亚里士多德记述了齿轮就好像是他们司空见惯的一样。

在十五世纪,达芬奇设计了大量的包含各种各样齿轮的设备。

Among the various means of mechanical power transmission (including primarily gears , belts , and chains ) , gears are generally the most rugged and durable . Their power transmission efficiency is as high as 98 percent . On the other hand , gears are usually more costly than chains and belts . As would be expected , gear manufacturing costs increase sharply with increased precision -- as required for the combination of high speeds and heavy loads , and for low noise levels . ( Standard tolerances for various degrees of manufacturing precision have been established by the AGMA , American Gear Manufacturers Association. )在众多的机械传动方式中(包括齿轮传动,带传动,链传动),一般来说,齿轮是最经久耐用的,它的能量传递效率高达98%。
