Abstract
The monitoring device is constructed in such a way that the temperature measurement takes place directly at the bearing and there is no need for detaching connecting lines during changing of rolls. The main features of the monitoring device for roll bearings, installed, for example, in the chock (1) of the work roll (3) of a roll stand, reside in a thermal limit value pickup (6) in contact with the roll bearing (7), as well as in a mechanical, spring-loaded transmission member (8) locked in place in the chock (1) by way of the limit value pickup, for acting on a signal generator (9) arranged outside of the chock (1) in the roll stand, this signal generator being actuated to shut down the rolling mill by automatic outward movement of the transmission member (8) after releasing its locking device by the limit value pickup (6) upon reaching a limit temperature of the roll bearing (7). The monitoring device is preferably intended for use in thin-gage strip and foil rolling mills having high rolling speeds.
