Abstract

A new type of externally pressurized infinite stiffness gas bearing is proposed. This bearing is constructed with a movable bush, a spring plate and two restrictors in series. This paper describes the bearing construction applying to a circular thrust bearing, working principle and analysis of the bearing performance. Calculated results show that the bearing has infinite stiffness in the neighbouring region of designed load. This is caused by the fact that the spring stiffness is linear but the change of bearing pressure is not linear to the shaft displacement.
