Abstract
Rotary bell cup atomizing apparatus driven by a turbine mounted on a rotatable motor shaft supported within an air bearing assembly is provided. The air bearing assembly includes a cylindrical main air bearing supporting the motor shaft, a proximal, annular, disk-shaped thrust bearing and a distal, annular, disk-shaped thrust bearing supporting the turbine, and including vibration-damping “O”-rings positioned adjacent the bearings. In operation, air supplied to the apparatus drives the turbine and supports the turbine and motor shaft such that all rotating surfaces of the atomizing apparatus are supported in air, and universal, 3-dimensional vibration damping, both axial and radial, of all rotating components is provided.
