题目：Lubrication and Journal Bearing
正文:The object of lubrication is to reduce friction,wear,and heating of machine parts which move relative to each other.A lubricant is any substance which,when inserted between the moving surfaces,accomplishes these purposes.In a journal bearing,the relative motion is sliding. In an antifriction bearing,the main relative motion is rolling. A follower may
either roll or slide on the cam. Gear teeth mate with each other by a combination of rolling and sliding. Pistons slide within their cylinders. All these applications require lubrication to reduce friction, wear,and heating.
The field of application for journal bearings is immense. The crankshaft and connecting-rod bearings of an automotive engine must operate for thousands of kilometers at high temperatures and under varying load conditions.The journal bearings used in the steam turbines of power-generating stations are said to have reliabilities approaching 100 percent. At the other extreme there are thousands of applications in which the loads are light and the service relatively unimportant. A simple, easily installed bearing is required,using little or no lubrication,In such cases an antifriction bearing might be a poor answer because of the cost ,the close tolerances,the radial space required , the high speeds ,or the increased inertial effects . Instead , a nylon bearing requiring no lubrication ,a powder-metallurgy bearing with the lubrication " built in ," or a bronze bearing with ring-oiled , solid-lubricant film , or grease lubrication might be a very satisfactory solution . Recent metallurgy developments in bearing materials,combined with increased knowledge of the lubrication process, now make it possible to design journal bearings with satisfactory lives and very good reliabilities.

Five distinct of forms of lubrication may be identified:
(a) hydrodynamic;
(b) hydrostatic;
(c) elastohydrodynamic;
(d) boundary;
(e) solid-film.

Answer 1

润滑轴承
正文：对象的润滑是减少摩擦，磨损，并加热零件的相对移动而每个other.A润滑剂是任何物质，当插入移动之间的表面，完成这些purposes.In杂志轴承，相对议案滑动。在减摩轴承，主要的相对运动是滚动。追随者可能
要么卷或幻灯片的凸轮。齿轮牙齿与队友互相相结合的滚动和滑动。活塞幻灯片在其汽缸。所有这些应用需要润滑，减少摩擦，磨损，和取暖。
在应用领域的轴承是巨大的。曲轴与连杆轴承的汽车引擎必须运行数千公里在高温下和在不同负荷条件轴承所用的蒸汽涡轮机发电站据说有信度接近百分之百。在另一个极端有数以千计的应用软件，其中轻负荷和服务相对不重要。一种简单，易于安装轴承需要，利用很少或根本没有润滑，在这种情况下的减摩轴承可能是一个贫穷的答案，因为成本，密切公差，径向所需的空间，高的速度，或增加惯性的影响。相反，尼龙轴承无需润滑，粉末，冶金轴承润滑“建造”或青铜轴承环油，固体润滑膜，或润滑可能是一个非常令人满意的解决办法。最近的事态发展冶金轴承材料，加上增加知识的润滑过程中，现在能够设计轴承满意的生活和非常好的可靠性。

五个不同形式的润滑可确定：
（一）动力;
（二）静;
（三）弹;
（四）边界;
（戊）固态薄膜。
