FIELD: machine building. ^ SUBSTANCE: gas bearing comprises bearing bush 23 surrounding space 22 accommodating supported body 34 and having its wall furnished with multiple feed channels 32, 33 made to feed compressed gas from outside. Said bearing bush 23 is made up of multiple elements 24, 25, 26, 27, 28. At least some feed channels 32, 33 are formed by grooves 32 in opposed surfaces 29 of adjacent elements 24, 25, 26, 27, 28. Invention covers also the method of fabricating said gas bearing that includes the following stages: a) producing multiple channels 24, 25, 26, 27, 28 to be communicated to form bearing bush 23 surrounding space 22; b) making grooves 32, 33, in at least one surface 29 of at least one of elements 25; 27 with its surface as-assembled faces surface of adjacent element 24; 26; 28; and c) jointing elements 24, 25, 26, 27, 28 together to make bearing bush 23. ^ EFFECT: minor cross section of feed orifices, stable geometry. ^ 19 cl, 7 dwg |
