Effects of Rotor Centrifugal Expansion on the Static and Dynamic Characteristics of Porous Gas Journal Bearing

Lubricants
As the rotational speed increases, the centrifugal expansion of the rotor will significantly affect the performance of the porous gas bearing. However, this rotor’s centrifugal effect has not been studied thoroughly.

Static characteristics of porous journal bearings with nonuniform permeability.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1988
The static characteristics of oil-filled porous journal bearings with nonuniform permeability are theoretically investigated. In this analysis, three types of nonuniform distribution of permeability are analyzed. For the first typed, the permeability varies in a radial direction, i.e., the permeability of the inside part is lower than that of the ...

Static characteristics of porous journal bearings with anisotropic permeability.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1988
The static characteristic of oil filled porous journal bearings with anisotropic permeability are theoretically investigated. Considering anisotropic permeability, the Reynolds equation for the oil film is modified to include the effect of tangential velocity slip at the interface between the oil film and the porous medium, and the pressure equation ...

Modeling and simulation of porous journal bearings in multibody systems

, 2013
A specific cost-efficient type of plain journal bearing is the porous journal bearing, which possesses a pervious bush that serves as a lubricant reservoir. The current work is concerned with modeling porous journal bearings in multibody systems, for which dynamical models are needed to investigate the bearing’s behavior.
