Diagnostic research of adaptive hydrodynamic segmental bearings with elastic ring in a rotor system

Abstract

Research object which is described in this article is adaptive hydrodynamic bearing with connecting moving ring which connects segments. This construction of the bearings gives more stable work of the rotors in the wider diapason of rotation frequencies. These bearings have two flows of lubricant: carrying and circulating. Elastic ring is damping whirls of circulating flow and decreasing the in-fluence of rotor rotation frequencies on excitation of vibra-tion. A mechanism of experimental research and method-ology of experimental research is given. Results of the experimental research are obtained, they are discussed and conclusions are formulated.
