This book was released on 1963 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The best operating lifetimes in a vacuum were achieved with oil and grease lubricants. Of the 37 tests conducted with 28 oils, double-shielded bearings with vacuum impregnated paper base phenolic retainers lubricated with 4 oils (one low-volatility petroleum base oil and 3 halo genated silicones) gave lifetimes of over 1 year. Of 13 greases evaluated in 16 tests, 4 greases, composed of silicone oils in shielded bearings showed lifetimes of over 1 year. On the basis of coast times, torque was abousame for oil lubricated bearings with phenolic retainers as for the grease-lubricated bearings with metal ribbon retainers. Of the total oil tests in a vacuum, 1 oil (Apiezon K) has achieved 18,297 hours of test time and is still running. Of the total grease tests in a vacuum, 1 grease (Aero shell-15) has achieved 13,364 hours and is still running. Of the 29 tests conducted, on different dry-film lubricants, 15 showed poor reproducibil ity and all had limited lifetimes under a 100% duty cycle. The maximum lifetime achieved was 2,213 hours. However, similar tests on the same material gave test times of 876, 245, 342, and 132 hours. Eight self- lubricating retainer materials were evaluated in 19 tests. Two poly tetrafluoroethylene compositions gave the best results: 5,000 and 3,000 hours. (Author).

Download or read book Fundamentals of Fluid Film Lubrication written by Bernard J. Hamrock and published by CRC Press. This book was released on 2004-03-15 with total page 747 pages. Available in PDF, EPUB and Kindle. Book excerpt: Specifically focusing on fluid film, hydrodynamic, and elastohydrodynamic lubrication, this edition studies the most important principles of fluid film lubrication for the correct design of bearings, gears, and rolling operations, and for the prevention of friction and wear in engineering designs. It explains various theories, procedures, and equations for improved solutions to machining challenges. Providing more than 1120 display equations and an introductory section in each chapter, Fundamentals of Fluid Film Lubrication, Second Edition facilitates the analysis of any machine element that uses fluid film lubrication and strengthens understanding of critical design concepts.

Download or read book Materials and Processes written by Barrie D. Dunn and published by Springer. This book was released on 2015-12-29 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this book is to assist scientists and engineers select the ideal material or manufacturing process for particular applications; these could cover a wide range of fields, from light-weight structures to electronic hardware. The book will help in problem solving as it also presents more than 100 case studies and failure investigations from the space sector that can, by analogy, be applied to other industries. Difficult-to-find material data is included for reference. The sciences of metallic (primarily) and organic materials presented throughout the book demonstrate how they can be applied as an integral part of spacecraft product assurance schemes, which involve quality, material and processes evaluations, and the selection of mechanical and component parts. In this successor edition, which has been revised and updated, engineering problems associated with critical spacecraft hardware and the space environment are highlighted by over 500 illustrations including micrographs and fractographs. Space hardware captured by astronauts and returned to Earth from long durations in space are examined. Information detailed in the Handbook is applicable to general terrestrial applications including consumer electronics as well as high reliability systems associated with aeronautics, medical equipment and ground transportation. This Handbook is also directed to those involved in maximizing the relia bility of new materials and processes for space technology and space engineering. It will be invaluable to engineers concerned with the construction of advanced structures or mechanical and electronic sub-systems.
