This book has been written to meet the course on tribology-friction, wear, lubrication and bearing of Mechanical, Civil, Automobile and Aeronautical Engineering Curriculum for the undergraduate and postgraduate students. The book is especially useful for the researchers, practicing engineers and professionals for their general requirements. The book provides a simple, clear and exhaustive treatment of friction, lubrication, bearing and wear data. The text in this volume covers the topics such as introduction, meaning, and disciplines of tribology; wear and its types; theories, causes, uses, and measurement methods of friction; properties, functions, advantages, and types of lubricants; design, journal, and materials of bearings; and surface topography and its techniques

    Tribology Price 2.99  |  2.99 Rewards Points

    Tribology, the concept which focuses on friction, wear and lubrication of interacting surfaces in relative motion. Tribology is based on that when two bodies moving, sliding on each other then friction occurs Fig. 1.1. Tribology in a traditional form has been in existence a well studied examples of how early civilizations developed in bearings and low friction surfaces. The study of tribology the basic laws of friction, such as the proportionality between normal force and limiting friction force. understanding of friction and wear in the surface of the bodies, to explain the underlying mechanisms. The relatively low priority of tribology concept that nobody really bothered what would happen when motion between the spheres and surfaces was in a downward direction. Tribology is the field of science which studies the improved friction control. The work of Reynolds initiated countless research efforts aimed at parts of improving the interaction between two contacting surfaces. As a result journal bearings are now designed to high level of sophistication. Wear and the fundamentals effect of friction are far more complex problems, the experimental investigation based on advanced instrumentation scanning electron microscopy and atomic forces microscopy. Tribology is according to the fig. 1.1 shows is the study of the wear, friction and lubrication.

    Wear Price 2.99  |  2.99 Rewards Points

    Wear is the erosion or damage of material from a solid surface by the mechanical action of another surface. It is related to surface interactions and more specifically the removal of material from a surface. Wear is occurred on the surfaces when friction is there between surfaces.

    Friction Price 2.99  |  2.99 Rewards Points

    Friction is the force resisting the relative motion of solid surfaces, fluid layers of particles or material elements sliding against each other when the surface are same or different materials. Friction is the “evil” of all motion. No matter which direction something moves in, friction pulls it the other way. Move something left, friction pulls right. Move something up, friction pulls down. It all depends on the movements of the objects. It appears as if nature has given us friction to stop us from moving anything from one side to another.

    Lubrication Price 2.99  |  2.99 Rewards Points

    Lubrication is the process, or technique employed to reduce wear when surfaces moving relative to each other, by interposing a substance called lubricant between the surfaces to carry or to help carry the load (pressure generated) between the opposing surfaces. The interposed lubricant film can be a solid, (e.g., graphite, MoS2)a solid/liquid dispersion, a liquid, a liquid-liquid dispersion or gasses exceptionally a gas.

    Bearings Price 2.99  |  2.99 Rewards Points

    Bearings are machine elements whose function is to bear load and promote smooth relative motion at low friction between solid surfaces. The surfaces might be in direct contact, but if they are not, the lubricant film separating them can be liquid, gaseous, or solid. Bearing which are used for the movements of the surfaces. The maximum film pressure is of the same order of magnitude as the specific bearing load, defined by P = W/A, where W is the external load and A is the projected (normal to the load) bearing area. The elastic deformation of the solid surfaces forms an essential component of the analysis of these bearings

    Surface Topography Price 2.99  |  2.99 Rewards Points

    A tribological system consists of the surfaces of two components that are in moving contact with one another and their surroundings. progress and extent of wear are determined by the materials and finishes of the components, any intermediate materials, surrounding influences and operating conditions.
