Design and fast verification of pocket elliptical journal bearings
Abstract
Purpose
The purpose of this paper was to conceive a fast method to verify design and performance of elliptical pocket journal bearings.
Design/methodology/approach
The computer-aided verification of pocket journal bearings is performed by means of a suitable finite element analysis method.
Findings
The results of sample analyses indicate that the machining tolerances are very influential on elliptical pocket bearing performances, and they must be included among the input data.
Originality/value
Although elliptical pocket bearings are widely used in turbomachineries, the influence of their design on performance has not been specifically investigated. A lot of works about tribological models are available, but few of them focus on their application to bearing design at the industrial level.
Keywords
Acknowledgements
The author would like to acknowledge Alessandro Reppa and his Department of Ansaldo Energia (Genoa) for providing information on and measurements of the bearing in the study.
