Investigation of oil whip and whirl influence rotor system with hydrodynamic adaptive segmental bearing of working stability

Abstract

This paper presents tests of the effects oil creates to working performance of bearing rotor system. The object of investigation is rotor system, rotor-oil-hydrodynamic adaptive segmental bearings with segments connecting elastic elements. Elastic elements inhibit the oil flow turbulence and so reduce rotor vibration alarm. With such structure of bearing can achieve stable rotation of the rotor work in a wider range of frequencies. These bearings have two oil streams: the carrying and circulation. It is presents separate models of bearing segments being different load cases. It is used stand with special diagnostic equipment for experimental research. Investigations were carried out rotor systems working range from 0 to 6000 rev/min. After investigations is determined influence in the bearing of lubricant whirls for the stability and reliability of rotor system work.
