Abstract

The article discusses unconventional bearing systems for high-speed rotors, which are used in micro-power turbomachines. Various bearing systems are presented in the subsequent sections of the article, with an indication of their main properties, advantages and disadvantages as well as restrictions associated with their use. Particular attention has been paid to gas foil bearings and bearings lubricated with the vapours of a low-boiling medium. In addition, the results of our own research related to the two above-mentioned bearing types are presented. The research was carried out under the framework of works aimed at selecting bearing systems for vapour microturbines suitable for the operation in ORC systems. The information given herein may be helpful for re-searchers or engineers who need to select a bearing system for a novel high-speed fluid-flow machine that has to withstand harsh operating conditions.
