THE PERFORMANCE CHARACTERISTICS OF COMPLIANT SHELL LEMON BORE BEARINGS

Lemon-bore bearings are quite popular in high speed applications. In this paper the effects ot bearing deformation on the performance characteristics of lemon shaped journal bearing systems are determined. Modifying the extent of film in each lobe with shell deformation, the results are cal- culated for wide range of operating eccentricity and different values of ellipticity ratio and defor- mation coefficient. This study reveals many favourable changes in performance characteristics of the journal bearing system if supported on flexible bearings.
