LUBRICATION

CHAPTER 2 : LUBRICATION What is Lubrication?? Wear is a major cause of material wastage,so any reduction of wear can effect considerable saving. Friction is a principal cause of energy dissipation and considerable savings are possible by improved friction control. The most effective mean of controlling wear and reducing friction. Lubrication as part of tribology, which is the science and technology of friction lubrication an wear. Lubrication Principle To reduce friction between any two relatively moving or sliding surfaces by the interposition of a lubricant between them. The act of applying lubricants and lubrication substances which are capable of reducing friction between moving mechanical parts. Type of lubrication Fluid or hydrodynamic lubrication Thin film or boundary  Extreme pressure  Type of lubricant Solid lubricant Semi solid lubricant Liquid lubricant Emulsion lubricant Type of automatic lubrication syste
