Abstract

Floating ring bearing has the characteristics of simple structure, low power consumption and high efficiency. It is suitable for high speed and light load occasions. It has been widely used in high speed rotating machinery such as turbo charger, aviation engine and so on. Firstly, the materials of each component of the turbocharger rotor system are selected. Secondly, parameterized model of turbocharger floating ring bearing was established by the software DyRoBes-Beperf, when ring ratio is constant analysis of oil film pressure distribution for floating ring bearing were conducted, and eccentricity, oil film stiffness, damping variation with speed. The calculation in this paper provides some reference for the design and analysis of the turbine rotor and the floating ring bearing.
