Abstract
A bearing arrangement which is to be used for supporting a rotatable shaft used in a system employing a pressurized medium at a pressure which is partially dependent on the speed of rotation of the shaft includes a main bearing sleeve mounted on a support and surrounding the shaft. The working medium is supplied between the shaft and the bearing sleeve to fully support the shaft in the bearing sleeve when the pressure of the working medium exceeds a predetermined value. The bearing arrangement further includes at least one, but possibly more than one, auxiliary bearing including a split bearing ring which has a conical outer circumferential surface and a stationary outer bearing ring surrounding the split bearing ring and having a conical inner ramp surface. A resilient spring acts on the split bearing ring in one axial direction of the shaft against pressure forces of working medium to cause the contact surface to slide on the ramp surface with an attendent reduction in the transverse dimensions of the split bearing ring to bring the inner surface of the split bearing ring into supporting contact with the shaft for the auxiliary bearing to furnish at least a portion of the required supporting effect when the pressure of the working medium is below the predetermined value.
