High-speed air bearing spindle using radial air bearing with nozzle and pocket-line

摘要

A plurality of pocket lines (7) having grooves arranged in a circumferential direction so as to maintain the pressure of the radial air bearings on the inner diametric side of the radial bearing are provided in the form of an integral pipe, not a method of assembling the orifices to the bearing body. And a plurality of air supply nozzles 6 (fine holes) formed as fine holes and spaced apart from each other by a predetermined distance are provided in the respective pocket lines 7, and a nozzle having a function as a radial air bearing and a lady The present invention relates to an air bearing and a high-speed air bearing spindle using the same.
