Method and device for monitoring a bearing arrangement
First Claim
1. A method for monitoring a bearing arrangement in a stand in a rolling mill train that mills metal, the stand including a plurality of rollers, at least one of the rollers provided with a roller journal seated in a mounting element 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 mounting element by way of a sensor mounted in the bearing arrangement or the mounting element;
providing the measured value of the process quantity to an evaluation device;
comparing the measured value of the process quantity with a stored preset value; and
triggering a signal when the measured value of the process quantity exceeds or falls below the stored preset value.

Abstract
A method and a device for monitoring a bearing arrangement, having at least one bearing, in a mounting element of a roller journal bearing of a roller in a stand of a rolling mill train are designed to initiate upkeep or repair work on the bearing arrangement at the correct time. The method involves measuring 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.
