Abstract:
A method (100) for operating a gas bearing (1), wherein the gas bearing is formed by a rotor (11) and a stator (12), wherein when there is rotation against a stator (12) with a lift-off rotational speed nL the rotor (11) changes from mixed friction with the stator (12) into fluid friction with a medium (13) located between the stator (12) and the rotor (11), wherein the rotational speed of the rotor (11) is kept at or above an idling rotational speed nI, wherein—in response to a first information item (21), on the basis of which a change ΔF is to be expected in the acceleration forces F acting on the gas bearing (1), a new value of a safety factor rN:=nI/nL between the idling rotational speed nI and the lift-off rotational speed nL is determined (110), and/or—in response to a second information item (31), on the basis of which a change ΔnL is to be expected in the lift-off rotational speed nL, a new value nL,neu is determined for the lift-off rotational speed nL (120), wherein the idling rotational speed nI of the gas bearing (1) is adapted to the changed value of the safety factor rN, and/or to the changed value nL,neu of the lift-off rotational speed nL, (130). The invention further relates to an associated computer program.
