ABSTRACT:
The invention is directed to an improvement for a twin drive rolling mill wherein upper and lower rollers are connected with the rotor shafts of corresponding drive motors through respective transmission chains. An elevated bearing support platform is provided over which the upper-roller transmission chain is guided. Each transmission chain includes a coupling that permits longitudinal displacements, a spindle, and an axial pressure bearing. The upper-roller transmission chain further includes an intermediate shaft, a radial bearing mounted on the support platform for accommodating the intermediate shaft, and a support-beam structure arranged laterally of the spindle for supporting the spindle. The improvement includes a lever pivotally mounted on the elevated bearing support platform and a connection bolt for connecting the support-beam structure to the lever. The bolt is constructed to rupture upon the application of a predetermined force between the lever and the support platform to thereby prevent excessive forces from being transmitted to the latter.
