Abstract
A method for determining an operating condition of at least one plain bearing includes measuring, by a sensor, structure-borne noise arising from a toothed engagement of a first gear and a second gear, wherein the first gear is rotatably mounted via the plain bearing and meshes with the second gear. The method further includes assigning, to a signal of the sensor, a variable that correlates with the operating condition of the plain bearing.
