The book reviews the physical and chemical aspects of grease lubrication, primarily directed towards lubrication of rolling bearings.The first part of the book covers grease composition, properties and rheology, including thermal and dynamics properties. Later chapters cover the dynamics of greased bearings, including grease life, bearing life, reliability and testing. The final chapter covers lubrications systems - the systems that deliver grease to the components requiring lubrication.Grease Lubrication in Rolling Bearings: Describes the underlying physical and chemical properties of grease. Discusses the effect of load, speed, temperature, bearing geometry, bearing materials and grease type on bearing wear. Covers both bearing and grease performance, including thermo-mechanical ageing and testing methodologies. It is intended for researchers and engineers in the petro-chemical and bearing industry, industries related to this (e.g. wind turbine industry, automotive industry) and for application engineers. It will also be of interest for teaching in post-graduate courses"--$cProvided by publisher. 410 0$aTribology in Practice Series 606 $aRoller bearings$xLubrication 606 $aLubrication and lubricants 615 0$aRoller bearings$xLubrication. 615 0$aLubrication and lubricants. 676 $a621.8/9 676 $a621.822 676 $a621.89 686 $aTEC006000$2bisacsh 700 $aLugt$b Piet M$01715384 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910830283203321 996 $aGrease lubrication in rolling bearings$94109970 997 $aUNINA
