Download or read book Factors Affecting Simulated Service Tests of Greases written by Sidney M. Collegeman and published by . This book was released on 1949 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: There have been many attempts to establish a reliable means for predicting the service life of a grease. Greases have been selected on the basis of composition, physical characteristics, and operation in actual equipment. More recently, simulated-service tests have been used and have been accepted as a dependable means of evaluating greases. These tests are in most cases less time consuming than those in actual standard equipment. However, there is still a need for a means of accelerating testing to obtain results in a shorter time without reducing their reliability. This paper deals with our attempts to accomplish this objective. The initial work on the evaluation of greases by performance tests led to the development of the Navy Grease Machine. This work was described by Adams and Patten in 1941. This machine was abandoned when reports from the field indicated that the premises on which its evaluation of greases was based were invalid. It then was necessary to devise a test which would more nearly simulate service conditions. Simulated-service testing of greases under conditions of high temperature and high speed was started with an apparatus designed to rotate a No. 204, grease-lubricated ball-bearing at 10,000 rpm. while maintaining any desired temperature. A Specification for High Temperature Water Resistant Grease was subsequently written around this apparatus using as the criterion of acceptability a minimum of 300 hr. satisfactory bearing operation at a temperature of 300 F. This work was summarized last year by Adams and Collegeman. The information and experience gained with this apparatus were used to design and construct an improved tester which permits better control of more variables. This apparatus has been given the name of Universal Grease Tester, a single unit of which is illustrated in Fig. 1. This apparatus recognizes and provides control of four variables: temperature, speed, bearing size, and bearing load, both radial and axial. Permissible temperatures with this installation range up to 500 F., speeds up to 20,000 rpm., bearing sizes up to 60-mm. bore, and bearing loads up to 50 lb. The radial-load range can be extended readily by modification of accessories without changing the basic design of the unit. In order to obtain in a reasonable time sufficient replicate runs for appraisal of both the magnitude and the variability of the results, thirty units of this tester have been installed. Two views of the assembly are shown in Figs. 2 and 3.

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 2013-02-18 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.

Download or read book A Journal Bearing Test Rig With Reduced Uncertainty written by D. Wale and published by . This book was released on 2007 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents results from a design study for a new journal bearing test rig intended to set new standards of accuracy. The paper summarizes a review of previous rigs and experimental techniques, with consideration and selection of the general design features most likely to give high accuracy in a new rig. Certain sources of error are identified and described, including those associated with the measurement system and build errors. A numerical assessment of the sensitivity to errors in selected experimental configurations is presented. In addition, methods of controlling uncertainties are discussed. This paper would be of interest to practicing engineers and researchers, either already involved, or new, to experimental journal bearing testing.

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 Strengthening Forensic Science in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-07-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.
