Available in PDF, EPUB and Kindle. Book excerpt: Oil lubricated bearings have been widely used in variety of turbo machinery, though it has its own limitations such as thermal degradation of oil over temperature, complicated oil lubrication system and their maintenance. Commercial application of the air foil bearing (AFB) in Microturbomachinery have been acknowledged. Microturbomachinery term is used in applications with shaft power less than 1000KW and shaft diameter less than 100mm. Microturbomachinery has demanded light weighted, compact, extreme temperature and high speed operation. DN number for oil lubricated bearings and rolling element bearings is very less when compared to foil bearings. Absence of external pressurizing and lubricating system makes the system light and compact. Simple construction, low friction drag and reliability at high speed operations are few more advantages of the foil bearings. With all these advantages, foil bearings appears to be the one of the most effective techniques for Microturbomachinery. With the relentless demand for machines capable of operating at greatest speeds, high power densities and temperatures, foil gas bearings represent an enabling technology for advanced oil free system. While air foil journal bearings have been advanced significantly in past decades, very few literature data are available and not much experimental work has been conducted on foil thrust bearings. There is comparatively less information on air foil thrust bearings due to challenges in design, manufacturing and assembly. This research focuses on development of foil gas thrust bearing test rig which will operate at high temperature and speed. The test rig developed is equipped with thermocouple, optical probe, load cell which provides temperature, axial load, torque and high speed data by using NI labview. Design, manufacturing and assembly of air foil thrust bearing are detailed. The test rig has a push/pull mechanism which makes the stiffness measurement much easier. By evaluating parameters such as load capacity, steady state temperature, structural stiffness, and start stop friction torque will help to enhance the performance of the air foil thrust bearing.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An oil conditioning system was designed and fabricated to be used in a research project for hydrodynamic thrust bearings. Once fabrication was completed, the system was integrated into a new hydrodynamic thrust bearing (HTB) testing system. The oil conditioning system was designed to function with specifications provided by the project sponsor Miba Bearings US, LLC. This thesis covers details of flow schematics, CAD models, Mechanical and thermal simulations, simulated heat load testing, and in-service HTB testing of the oil conditioning system

Download or read book A Foil Thrust Bearing Test Rig for Evaluation of High Temperature Performance and Durability written by and published by . This book was released on 2008 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new test rig is designed to evaluate the start-stop cyclic durability of high-temperature solid lubricant coatings applied to foil thrust bearing systems. This test rig also allows the characterization of low speed thrust bearing performance, augmenting existing high speed test capabilities. The Low-Speed Thrust Bearing Rig is designed to test foil thrust bearings at speeds up to 21,000 rpm and temperatures up to 540 deg C (1000 deg F), with variable thrust loads. Thrust bearings can be subjected to tens of thousand of start-stop cycles to simulate decades of service in a turbomachinery application. Initial testing has validated the rig capabilities by subjecting a bearing and thrust runner to more than two thousand start/stop cycles at a temperature of 430 deg C (800 deg F).

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.
