Patent ID: 7784380

Claim:
Drive spindle for the main drive of a rolling stand, which has: a first shaft ( 3 ) for transmitting torque from a drive motor ( 2 ) to a coupling element, and a second shaft ( 5 ) for transmitting the torque from the coupling element via a swivel joint ( 4 ) to a roll ( 6 ) of the rolling stand, wherein the swivel joint ( 4 ) has a wobbler ( 7 ), which is rotationally rigidly connected with the roll ( 6 ), and a second spindle head ( 8 ), which is rotationally rigidly connected with the second shaft ( 5 ), and wherein the rotational connection between the wobbler ( 7 ) and the spindle head ( 8 ) is produced by sliding bearings and a journal ( 9 ), which is rotationally rigidly connected with the spindle head ( 8 ) but is supported in a way that allows an angle of inclination (a) between the axis of rotation ( 10 ) of the roll ( 6 ) and the axis of rotation ( 11 ) of the second shaft ( 5 ), wherein a bearing element ( 12 , 13 ) for absorbing forces in the direction of the axes of the second shaft ( 5 ) and the roll ( 6 ) is arranged between the wobbler ( 7 ) and the spindle head ( 8 ), such that a push rod ( 14 ) for transmitting axial forces between the wobbler ( 7 ) and the spindle head ( 8 ) is arranged between the two bearing elements ( 12 , 13 ).
