Abstract
A device for monitoring the lubrication condition of the bearing of a track roller of a running gear of a tracked vehicle by means of temperature monitoring, wherein the track roller has at least one bearing journal, wherein the track roller is mounted in a frame of the tracked vehicle via the bearing journal, wherein a sensor arrangement is arranged in the region of the bearing journal, wherein the sensor arrangement is set up to transmit temperature data measured by the sensor arrangement wirelessly to a further processing device.
Claims15
A device for monitoring a lubrication condition of a bearing of a track roller of a running gear of a tracked vehicle, the track roller having at least one bearing journal, wherein the track roller is configured to be mounted within a frame of the tracked vehicle via the bearing journal, the device comprising:
- a sensor arrangement arranged in a region of the bearing journal, wherein the sensor arrangement is configured to transmit temperature data measured by the sensor arrangement wirelessly to a further processing device, wherein the sensor arrangement is arranged on a fastening screw, wherein the fastening screw is screwed into a threaded bore provided in the bearing journal, wherein the track roller is configured to be fastened to an element of the frame by the fastening screw, wherein the sensor arrangement includes a temperature sensor configured to measure instantaneous temperature data, wherein the sensor arrangement includes an RFID transponder for temperature data acquiring, wherein a reader is provided at a distance from the RFID transponder for reading out the acquired temperature data, and wherein the reader is configured for transmitting the temperature data to the further processing device for further processing.
A method for monitoring a lubrication condition of a bearing of a track roller of a running gear of a tracked vehicle, wherein the temperature monitoring is carried out during operation of the tracked vehicle by a sensor arrangement, wherein the track roller is mounted in a frame of the tracked vehicle via at least one bearing journal, wherein the sensor arrangement is arranged in a region of the bearing journal, wherein the sensor arrangement is arranged on a fastening screw, wherein the fastening screw is screwed into a threaded bore provided in the bearing journal, wherein the track roller is fastened to an element of the frame by the fastening screw, wherein the sensor arrangement comprises a temperature sensor with which instantaneous temperature data are measured, the method comprising:
- acquiring a temperature data by the sensor arrangement, wherein the sensor arrangement comprises an RFID transponder with which the temperature data are acquired;
- transmitting the temperature data wirelessly to a further processing device;
- reading out the acquired temperature data a reader which is arranged at a distance from the RFID transponder;
- and
- transmitting the temperature data from the reader to the further processing device for further processing.
