Wraps. Zustand: Good. Second printing [stated]. vii, [1], 511, [1] pages. Wraps. Covers have some wear and soiling. Ex-library with usual library markings. Stamp and ink mark on front cover. Ink mark inside rear cover. The two authors were associated with the Lewis Research Center in Cleveland, Ohio. Chapter 5 on Gas-lubricated…bearings was by J. A. Ausman and Chapter 7 on Liquid Lubricants was by Douglas H. Moreton. All other chapters were written by one or the other of the principal authors. Bisson retired from NASA in 1973 and was noted as the scientist who decades earlier had introduced Tribology to the National Advisory Committee on Aeronautics (the predecessor of NASA.) A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts. Most bearings facilitate the desired motion by minimizing friction. Bearings are classified broadly according to the type of operation, the motions allowed, or to the directions of the loads (forces) applied to the parts. Rotary bearings hold rotating components such as shafts or axles within mechanical systems, and transfer axial and radial loads from the source of the load to the structure supporting it. The simplest form of bearing, the plain bearing, consists of a shaft rotating in a hole. Lubrication is often used to reduce friction. In the ball bearing and roller bearing, to prevent sliding friction, rolling elements such as rollers or balls with a circular cross-section are located between the races or journals of the bearing assembly. A wide variety of bearing designs exists to allow the demands of the application to be correctly met for maximum efficiency, reliability, durability and performance. The term "bearing" is derived from the verb "to bear"; a bearing being a machine element that allows one part to bear (i.e., to support) another. The simplest bearings are bearing surfaces, cut or formed into a part, with varying degrees of control over the form, size, roughness and location of the surface. Other bearings are separate devices installed into a machine or machine part. The most sophisticated bearings for the most demanding applications are very precise devices; their manufacture requires some of the highest standards of current technology.
