| Abstract: | As compared with other types of bearing, EP(exlernally pressurized) air bearing has some advantages-very tiny frictional coefficient, very high spindle turning accuracy and non-pollution etc. EP air bearings are widely used in precision machine. This paper solves load capacity and pressure distribution of EP air bearing by using finite element method and shows applications of EP air bearing to rainbow gratings and information memory in LASER. |
