An Experimental Study of a Self-Acting Foil Bearing at Low Values of Foil Tension

摘要

Theoretical solutions for the gap thickness in an infinitely wide foil bearing are reviewed. An experiment is described using a stainless steel foil wrapped about a high speed rotor. Details of instrumentation are included. Results are presented for the relation between gap thickness and foil stiffness for low values of foil tension. (Author)
