Download or read book Predicted and Experimental Performance of Jet Lubricated 120 Millimeter Bore Ball Bearings Operating to 2 5 Million Dn written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-08-06 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bearing inner- and outer-race temperatures and friction power losses were calculated using two computer programs. The values obtained were compared with previously reported experimental data for 120 mm bore bearings which operated at thrust loads to 22 240 N (5000 lb), shaft speeds to 20 800 rpm, and with two lubricant flow rates. One program severely underestimated the power loss, while the other, called SHABERTH, provided a good prediction of both race temperatures and power losses. Coe, H. H. and Zaretsky, E. V.

Download or read book Advanced Dynamics of Rolling Elements written by P.K. Gupta and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: In any rotating machinery system, the bearing has traditionally been a crit ical member of the entire system, since it is the component that permits the relative motion between the stationary and moving parts. Depending on the application, a number of different bearing types have been used, such as oil-lubricated hydrodynamic bearings, gas bearings, magnetic suspensions, rolling element bearings, etc. Hydrodynamic bearings can provide any desired load support, but they are limited in stiffness and the associated power loss may be quite large. Gas bearings are used for high-precision applications where the supported loads are relatively light, bearing power losses are very low, and the rotating speeds generally high. For super precision components where no frictional dissipation or bearing power loss can be tolerated, magnetic suspensions are employed; again, the load support requirements are very low. Rolling element bearings have been widely used for those applications that require greater bearing versatility, due to the requirements for high-load and high-stiffness characteristics, while allowing moderate power loss and permitting variable speeds. A study of the dynamic interaction of rolling elements is, therefore, the subject of this text. Texts covering the analysis and design methodology of rolling elements are very limited. Notable works include Analysis of Stresses and Deflections (Jones, 1946, Vols. I and II), Ball and Roller Bearings, Their Theory, Design and Application (Eschmann, Hasbargen, and Weigand, 1958), Ball and Roller Bearing Engineering (Palmgren, 1959, 3rd ed. ), Advanced Bearing Technology (Bisson and Anderson, 1965), and Rolling Bearing Analysis (Harris, 1966).

Available in PDF, EPUB and Kindle. Book excerpt: Plant engineers are responsible for a wide range of industrial activities, and may work in any industry. This means that breadth of knowledge required by such professionals is so wide that previous books addressing plant engineering have either been limited to only certain subjects or cursory in their treatment of topics. The Plant Engineering Handbook offers comprehensive coverage of an enormous range of subjects which are of vital interest to the plant engineer and anyone connected with industrial operations or maintenance.This handbook is packed with indispensable information, from defining just what a Plant Engineer actually does, through selection of a suitable site for a factory and provision of basic facilities (including boilers, electrical systems, water, HVAC systems, pumping systems and floors and finishes) to issues such as lubrication, corrosion, energy conservation, maintenance and materials handling as well as environmental considerations, insurance matters and financial concerns. One of the major features of this volume is its comprehensive treatment of the maintenance management function; in addition to chapters which outline the operation of the various plant equipment there is specialist advice on how to get the most out of that equipment and its operators. This will enable the reader to reap the rewards of more efficient operations, more effective employee contributions and in turn more profitable performance from the plant and the business to which it contributes.The Editor, Keith Mobley and the team of expert contributors, have practiced at the highest levels in leading corporations across the USA, Europe and the rest of the world. Produced in association with Plant Engineering magazine, this book will be a source of information for plant engineers in any industry worldwide.* A Flagship reference work for the Plant Engineering series* Provides comprehensive coverage on an enormous range of subjects vital to plant and industrial engineer* Includes an international perspective including dual units and regulations

Book excerpt: A beautiful model's death uncovers an ugly conspiracy stretching all the way to Westminster in Rosie Gilmour's darkest case to date. When Scots supermodel Bella Mason plunges to her death from the roof of a glitzy Madrid hotel, everyone assumes it was suicide. Except that one person saw exactly what happened to Bella that night, and she definitely didn't jump. But Millie Chambers has no one she can tell - an alcoholic and now sectioned by her bullying politician husband, who would believe her? And that's not all Millie knows. Being close to the heart of Westminster power can lead to discovering some awful secrets... Back in Glasgow, Rosie's research into Bella's life leads to her brother. Dan is now a homeless heroin addict, but what he reveals about Bella's early life is electrifying: organised sexual abuse in care homes across Glasgow. Bella had tracked him down so that they could tell the world their story. And now she's dead. As Rosie's drive to expose the truth leads her closer to Millie and the shameful secrets she has kept for so many years, it becomes clear that what she's about to discover could prove fatal: a web of sexual abuse linking powerful figures across the nation, and the rot at the very heart of the British Establishment...
