Apparatus for determining the actual state and/or the remaining service life of structural components of a work machine

An apparatus for determining an actual state and/or a remaining service life of structural components comprising large-diameter rolling bearings of a work machine, wherein the work machine comprises a construction machine, a material-handling machine and/or a conveyor machine, comprising:

• a sensor system for acquiring state information relating to a structural component, wherein the sensor system comprises at least one sensor from the group of sensors consisting of:
• oscillation sensors, temperature sensors, lubricant sensors, structure-borne sound sensors, acceleration sensors, displacement sensors and speed sensors;
• an evaluation device for evaluating acquired state information and determining the actual state and/or the remaining service life by a comparison with predetermined damage characteristics;
• an active database device for storing the damage characteristics;
• a determination device for determining the damage characteristics from design data of the structural component, wherein the design data comprises a number of rolling elements, a number of rows, and an intended speed;
• and
• an adjustment device for adjusting the predetermined damage characteristics on the basis of the state and/or the remaining service life information determined by the evaluation device, wherein the adjustment device is configured to adjust the damage characteristics stored by the active database device depending on at least one signal from the at least one sensor;
• wherein the adjustment device and the determination device are connected to the active database device.
