Abstract

See full text

A self-acting air bearing for a pressurized spindle air bearing includes a bearing that is located within a cavity of a housing. The bearing and cavity may be shaped as a segment of a sphere. The spindle may be connected to a pressurized air source which creates an air bearing within a gap that separates the bearing from the housing. The bearing is attached to a shaft that is rotated by a motor. Rotation of the bearing creates a flow of air within the gap. The cavity and/or bearing may have a slot which cooperates with the air flow to increase the pressure of the air bearing.
