Method and device for monitoring the pivot bearings, particularly the rolling bearings, of continuous casting supporting rollers mounted in a supporting roller stand of metal, especially steel, continuous casting devices
First Claim
1. A method of monitoring the rotary bearings, especially the roller bearings, of continuous casting support rollers which are journaled at both ends and/or centrally in a roller support frame of a metal and especially steel continuous casting apparatus, by means of sensors arranged in their proximity, characterized in that, for the determining the residual life of roller and/or plane bearings a continuous measurement and storage of the mechanical and/or thermal stresses (load collective) is carried out on at least one or on a plurality of rotary bearings or on selected groups of rotary bearings or on a component influenced by the roller bearings, the digital measurement results are processed in an evaluation and storage unit, and, from the totality of all loads a ratio is calculated from the load collective and the limiting load capacity of the respective rotary bearing.

Abstract
The invention relates to a method and device for particularly the rolling bearing (3a), if continuous casting supporting rollers (2), which are mounted on both sides and/or centrally in a supporting roller stand (1) of metal, especially steel, continuous casting devices, by using sensors arranged in the proximity. The invention does not make the exchange of the pivot bearings (3) dependent on the occurrence of damages but targets it at the cost-effectiveness and the most-measurement and storage of the mechanical and/or thermal stresses (load collective) on at least one or more pivot bearings (3) or on selected groups of pivot bearing (3) or on a part 1a) that influences that pivot bearing 3) are effected for determining the remaining serviceable life of the rolling bearings and/or slide bearings (3a). In addition, the digital mearsurement results are processed in an evaluation and storage unit (5; 6), and a ratio consisting of the load collective and of the limiting load capacity or the respective pivot bearing (3; 3a) is calculated from the total number of all stresses.

10. A device for mounting the rotary bearings, especially the roller bearings of continuous casting support rollers which are journaled at both ends or centrally of a support roller frame of a metal, especially a steel, continuous casting apparatus by sensors arranged in the proximity thereof,
characterized in that, at one or more selected rotary bearings (3) of a continuous casting support roller (2) journaled by means of rollers and/or plain bearings (3a) or on a component (1a) influenced by the rotary bearing (3) respectively, a measurement element (4) is arranged for a mechanical and/or for a thermal stress and that the measurement element (4) is connected with an evaluating unit (5) and/or a storage unit (6).
