Available in PDF, EPUB and Kindle. Book excerpt: Flexible-surface thrust and journal foil-bearings of novel design were fabricated, and their performance was convincingly demonstrated, both individually and jointly as a unified rotor-support system. A versatile rig was constructed and instrumented, and experimental results are copiously documented with graphs and oscilloscopic data of trajectories, waveforms, and scans of amplitude response. The thrust bearings combine advantages of surface compliance with the superior load capacity of the spiral-groove configuration. The flexible supports provide means of deliberate control of clearance topography, in contrast to bearings in which the formation of the lubricating wedge is casual and incidental. At speeds of 40,000 to 45,000 rpm and a mean clearance of the order of 15 to 20 micrometers (600 to 800 micro in.), the resilient, air-lubricated, spiral-groove thrust bearings comfortably support a load of 127 N (29 lb; 13 kgf), equivalent to 3.0 N/sq. cm. (4.5 lb/sq in, 0.31 kgf/sq cm). The construction of journal foil-bearings is extremely simple. In one design, a coiled ribbon of plane foil and a retaining cartridge constitute the only components. In another design, the plane foil is integral with a section preformed to an open octagon with rounded vertices. A radical departure from operational characteristics of rigid gas bearings is achieved.

This book was released on 1972 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of foil journal bearings for a NASA Brayton Cycle Unit (BRU) is presented. The study represents an extension of previous work in that it includes the effects of thermal expansion of foil-bearing components, as well as an improved model of the influence of foil flexure. The results presented give the bearing film thickness, the bearing stiffness, and the foil tension as functions of the operating temperatures and the elasto-hydrodynamic and geometrical parameters pertinent to the design of BRU foil bearings. A computer program for the evaluation of design data and for parametric studies is included.

This book was released on 2018-08-20 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: IFToMM conferences have a history of success due to the various advances achieved in the field of rotor dynamics over the past three decades. These meetings have since become a leading global event, bringing together specialists from industry and academia to promote the exchange of knowledge, ideas, and information on the latest developments in the dynamics of rotating machinery. The scope of the conference is broad, including e.g. active components and vibration control, balancing, bearings, condition monitoring, dynamic analysis and stability, wind turbines and generators, electromechanical interactions in rotor dynamics and turbochargers. The proceedings are divided into four volumes. This first volume covers the following main topics: Active Components and Vibration Control; Balancing; Bearings: Fluid Film Bearings, Magnetic Bearings, Rolling Bearings and Seals; and Blades, Bladed Systems and Impellers.
