Development of Compliant-Mounted Gas-Lubricated Journal Bearings with High-Speed, High-Load Capability.

Abstract

The report describes the development of compliant-mounted or, more accurately, compliant-pivot journal bearings. Bearings of 1.4 inches and 1.8 inches in diameter (L/D = 1) operated without whirl at 76,000 rpm. An inadvertent test malfunction subjected the bearings to shock loading which they sustained without significant damage. The 1.4 inch diameter bearing was loaded to approximately 19 psi at 60,000 rpm when journal contact occurred. Overloading produced obvious bearing wipe, but the bearings was re-run without re-work and performed satisfactorily. (Author)
