Abstract
A method and device for monitoring a bearing arrangement, having at least one bearing, in a housing of a roller journal bearing of a roller in a continuous casting installation are designed to initiate upkeep or repair work on the bearing arrangement at the correct time. The method involves measuring a value of a process quantity at the bearing or in an area adjoining the bearing, providing an evaluation device with the measured value of the process quantity, comparing the measured value with a stored preset value, and triggering a signal as soon as the measured value exceeds or falls below the stored preset value.
Claims28
A method for monitoring a bearing arrangement in a continuous casting installation which includes a plurality of rollers each provided with a journal seated in a housing by way of said bearing arrangement, the bearing arrangement having at least one bearing, the method comprising:
- measuring a value of a process quantity at the bearing or the housing by way of a sensor mounted in the bearing arrangement or the housing;
- providing an evaluation device with the measured value of the process quantity;
- comparing the measured value with a stored preset value;
- and
- triggering a signal when the measured value exceeds or falls below the stored preset value.
A continuous casting installation which processes metal from a casting die, comprising:
- a plurality of rollers each provided with a roller journal seated in a housing by way of a bearing arrangement, the bearing arrangement including at least one bearing;
- at least one sensor mounted in the bearing arrangement or the housing which monitors a value of a process quantity at the bearing or the housing;
- conducting means for conducting the monitored value of the process quantity to an evaluation device;
- comparing means for comparing the monitored value with a stored preset value;
- and
- means for triggering a signal when the measured value exceeds or falls below the stored preset value.
A continuous casting installation comprising;
- a plurality of rollers each provided at its ends with a bearing arrangement seated in a housing, the bearing arrangement including at least one bearing;
- at least one sensor positioned in the bearing arrangement or the housing to monitor a value of one of:
- a force acting on the bearing;
- moisture in the bearing or a moisture content of lubricant in the bearing;
- temperature prevailing in the bearing;
- deformation of the housing;
- vibration frequency or vibration amplitude of the bearing;
- vibration property of the bearing;
- number of revolutions of the bearing,
- comparing means for comparing the monitored value with a stored preset value;
- and
- means for producing a signal when the measured value exceeds or falls below the stored preset value.
