Book Description
Lubricants used in space mechanisms must be throughly tested prior to their selection for critical applications. Traditionally, two types of tests have been used: accelerated and full scale. Accelerated tests are rapid, economical, and provide useful information for gross screening of candidate lubricants. Although full-scale tests are more believeable because they mimic actual spacecraft conditions, they are expensive and time consuming. The spiral orbit tribometer compromises between the two extremes. It rapidly determines the rate of tribochemically induced lubricant consumption, which leads to finite test times, under realistic rolling/pivoting conditions that occur in angular contact bearings.

Book Description
Discusses the selection of bench tests and testing conditions to model the lubrication and wear properties of fluids used in industrial machines and components, such as compressors, pumps, chain drives, transmissions, and bearings. Based on a June 2000 symposium held in Seattle, the 23 papers are di

Book Description
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.
