Abstract:
Aerostatic airbearing, comprisinga) a counter body (2) having a counter surface (21),b) a bearing body (1), havinga bearing surface (11) arranged opposing the counter surface (21),a nozzle channel (12) formed therein ending at the bearing surface (11) and being connected to a pressure source supplying a feed pressure, anda micro channel structure (13) formed therein which extends along the bearing surface (11) being open towards the bearing surface (11), runs into the nozzle channel (12) and extends along the bearing surface (11), in at least one direction of the bearing surface (11), over the most part of the extent of the bearing surface (11), andc) a static characteristic curve of the carrying force as a function of the gap width between the bearing surface (11) and the counter surface (21), which curve is defined by the structures of the bearing body (1) and of the counter body (2) and by the feed pressure, whereind) the cross sections of the micro channel structure (13) are such small, that, at operating states of the characteristic curve, at which the carrying force is less than 50% of the maximum carrying capacity, the overall volume of channels of the micro channel structure (13) is less then 10%, of the volume between the bearing surface (11) and the counter surface (21).
