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.

Model-based method and system for monitoring the condition of a sliding bearing, particularly for wind turbines

In a planetary gear arrangement with a planetary gear which includes a rotating part and a non-rotating part, and with a sensor module for sensing properties of the planetary gear, the sensor module includes a sensor as well as a first sending/receiving unit and a second sending/receiving unit, wherein the sensor and the first sending/receiving unit are coupled and arranged at the rotating part, and wherein the second sending/receiving unit is arranged at the non-rotating part, wherein the first sending/receiving unit and the second sending/receiving unit are configured for being inductively coupled, wherein the first sending/receiving unit includes an energy storage, wherein the energy storage is configured for being charged during each turn of the rotating part for powering the sensor via the first sending/receiving unit in order to perform measurements.
