Abstract
A sensor arrangement is provided for measuring the load of a rolling bearing with an inner ring, an outer ring and rolling elements arranged between the inner ring and the outer ring. The sensor arrangement includes a first sensor device arranged on the inner ring and/or the outer ring and measuring a load over the entire circumference of the rolling bearing. The sensor arrangement further includes a second sensor device arranged within a rolling element and measuring a locally restricted load of the rolling bearing, the second sensor device being pre-calibrated and calibrates the first sensor device.
Claims11
A sensor arrangement for measuring the load of a rolling bearing, the rolling bearing including an inner ring, an outer ring and a plurality of rolling elements arranged between the inner ring and the outer ring, the sensor arrangement comprising:
- a first sensor device arranged on the inner ring and/or the outer ring and configured to measure a load over an entire circumference of the rolling bearing;
- and
- a second sensor device arranged within one of the plurality of rolling elements and configured to measure a locally restricted load of the rolling bearing, the second sensor device being pre-calibrated and further configured to calibrate the first sensor device.
A method for calibrating a sensor arrangement for measuring a load of a rolling bearing, the method comprising the steps of:
- providing a rolling bearing with an inner ring, an outer ring and a plurality of rolling elements arranged between the inner ring and the outer ring;
- providing a sensor arrangement including a first sensor device and a second sensor device;
- arranging the first sensor device on the inner ring and/or on the outer ring, the first sensor device being configured to measure a load over an entire circumference of the rolling bearing;
- pre-calibrating the second sensor device and arranging the second sensor device within a rolling element;
- measuring a locally restricted load of the rolling bearing using the second sensor device;
- and
- calibrating the first sensor device based on the measured locally restricted load of the rolling bearing.
