The Role of Radial Clearance on the Performance of Foil Air Bearings Load capacity tests were conducted to determine how radial clearance variations affect the load capacity coefficient of foil air bearings. Two Generation III foil air bearings with the same design but possessing different initial radial clearances were tested at room temperature against an as-ground PS coated journal.

Radial Clearance Found To Play a Key Role in the Performance of Compliant Foil Air Bearings. By Kevin C. Radil. Get PDF ( KB) Abstract. Compliant foil air bearings are at the forefront of the Oil-Free turbomachinery revolution, which supports gas turbine engines with hydrodynamic bearings that use air instead of oil as the working fluid. For bearings such as single-row deep-groove ball bearings and spherical roller bearings, the mounted axial clearance or endplay is about 5 to 10 times the mounted radial internal clearance. In. Radil, K., Howard, S., Dykas, B., , “The role of radial clearance on the performance of foil air bearings,” STLE Tribology Transactions, 45, pp. – Foil air bearings can offer substantial improvements over traditional rolling element bearings in many applications and are attractive as a replacement to enable the development of advanced The Role of Radial Clearance on the Performance of Foil Air Bearings.

Load capacity tests were conducted to determine how radial clearance variations affect the load capacity coefficient of foil air bearings. Two Generation III foil air bearings with the same design. This article presents the results of experimental studies on the effects of mechanical preload and bearing clearance on the rotordynamic performance of lobed gas foil bearings (GFBs) for oil-free turbochargers (TCs). The lobed GFBs have a first-generation bump-type configuration within a lobe-like inner surface bearing housing. The Role of Radial Clearance on the Performance of Foil Air Bearings. Article. Two Generation III foil air bearings with the same design but possessing different initial radial clearances were.   The wing foil bearing has all the features required to achieve state-of-the-art performance (Gen III for radial bearings). This paper describes two radial foil bearings using the wing foil and the unique design features. Test data for a mm diameter bearing operating in air and in steam up to 42 krpm are presented to demonstrate the.
