This book was released on 1969 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the first twelve month's effort on a program that has as its objective the development of improved self-contained, solid lubricated ball bearings capable of long-term operation under high speed - high load - high temperature conditions. The program encompasses a temperature range of -40 to 1500 deg F and speeds up to 30,000 rpm. A maximum load combination of 250 lbs thrust/250 lbs radial is being investigated. Studies to date have established the feasibility of operating 207 system solid lubricated ball bearings at 10600 rpm and 600 deg F for at least 90 hours under a combined load of 250 lbs thrust/250 lbs radial. In addition, improvements in retainer design, fabrication techniques, and composite properties have resulted in increasing the life of the 204 and 207 system at 600 deg F from an average of 200 hours to an operating life of 370 and 456 hours respectively. The bearings were operated at a speed of 10600 rpm under a 50 lb thrust/50 lb radial load. Finally, the operating life of the 204 bearing system at 20000 rpm and 600 deg F was increased to 101 hours from the maximum life of 2.7 hours obtained in the prior program. The bearing carried a 100 lb thrust/25 lb radial load and conformed in design to that derived from a computerized bearing design analysis performed for this program. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This report describes a thorough analysis of the heat transfer characteristics of solid lubricated bearings. Two major aspects are investigated. These are heat generation within the bearing, and bearing cooling techniques. Bearing heat generation was studied, both analytically and experimentally. Computerized heat generation predictions were made and compared to actual performance data. Bearing component experiments were conducted in order to determine material and geometric effects and the significance of the various heat transfer modes. In addition, the importance of bearing operating conditions upon heat generation was also determined. A number of bearing cooling techniques were investigated. The influence of bearing geometric changes and cooling medium supply methods were determined. Much of the data is presented in nondimensional form. In general, it was found that heat generation was more a function of bearing operating conditions, especially speed and thrust load, than bearing internal geometry. Direct jet impingement cooling appears to be the most effective bearing cooling technique.

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.
