Abstract
A method for monitoring a condition of a sliding bearing operated with lubricating oil for a rotating component includes calculating, by a control unit as an output variable of a sliding bearing model, a calculated value of a minimum gap thickness of the sliding bearing. The calculated value is calculated by orbit analysis from at least one physical sliding bearing model to which at least a rotational speed of the rotating component, a bearing load, and a temperature of the sliding bearing are supplied as input variables. The method further includes measuring, with at least one sensor, a minimum gap thickness to provide a measured value of the minimum gap thickness, and comparing the measured value of the minimum gap thickness with the calculated value of the minimum gap thickness for the purpose of adjustment.
