Abstract :
According to the finite differential method, the influences of the spiral angle and eccentricity ratios on moving of cavities of novel spiral oil wedge hybrid journal bearing are presented. Numerical results show that moving of cavities is great related with spiral angle and eccentricity ratios, then the change of them make moving direction of cavities entirely inverse, and make the rupture location great different. And that it makes us know well the position of the cavities erosion before the test measurement.
