Rayleigh step bearing uses
WebDec 20, 2024 · Rayleigh, dating back to 1918.1 By application of cal-culus of variation, Rayleigh analytically optimised the bearing geometry of an infinitely wide slider operating under incompressible flow with the objective of max-imising the LCC. The result was a step-bearing geom-etry, nowadays referred to as the Rayleigh step bearing. WebAbstract. This paper presents a new hydrodynamic seal, in which the pressure drops caused by the reverse steps reduce the hydrodynamic film force, while they scarcely affect the film stiffness if the step recesses are deep enough. Thus, the clearance is controlled at high …
