This book was released on 1966 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stress patterns in lubricated rolling-contact elements have been computed from surface pressures and temperatures between pairs of rolling disks, both cylindrical or both crowned, measured by means of evaporated surface transducers. The maximum mechanical shearing stresses computed for both cylindrical and crowned disks proved to be nearly equal to these that would have occurred under static contact, but the calculated depth of those stresses was reduced for cylindrical rollers in dynamic contact. The maximum shear reversals computed for rolling cylindrical disks were noticeably below the corresponding shear differences for the static cases. Local pressure anomalies such as the pressure spike in the one particular case chosen for investigation, did not seem to alter significantly the shear-stress patterns. Thermal shearing stresses do not appear to be a significant portion of the maximum stress, but do dominate over mechanical shearing stresses near the surface of the elements. Since the pressure distributions under lubricated contact seem to be dominated by the Hertz pattern, with only minor differences appearing with changes of lubricant, some reconsideration has been given to film thickness which is known to vary significantly with lubricant. Explanations have been sought for the unexpectedly thin films observed with polyphenyl ether at high rolling speeds. A new organization of non-Newtonian film thickness theory shows fair correlation with film measurements. An alternate theory considering thermal disturbances is being sought. (Author).

Download or read book Grease Lubrication in Rolling Bearings written by Piet M. Lugt and published by John Wiley & Sons. This book was released on 2012-12-10 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: The definitive book on the science of grease lubrication for roller and needle bearings in industrial and vehicle engineering. Grease Lubrication in Rolling Bearings provides an overview of the existing knowledge on the various aspects of grease lubrication (including lubrication systems) and the state of the art models that exist today. 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.
