Abstract
The invention concerns a drive spindle () for the main drive of a rolling stand, which has: a first shaft () for transmitting torque from a drive motor () to a coupling element, especially to a multiple spline profile, and a second shaft () for transmitting the torque from the coupling element, especially the multiple spline profile, via a swivel joint () to a roll () of the rolling stand, wherein the swivel joint () has a wobbler (), which is rotationally rigidly connected with the roll (), and a second spindle head (), which is rotationally rigidly connected with the second shaft (), and wherein the rotational connection between the wobbler () and the spindle head () is produced by sliding bearings and a journal (), which is rotationally rigidly connected with the spindle head () but is supported in a way that allows an angle of inclination (α) between the axis of rotation () of the roll () and the axis of rotation () of the second shaft (). In order to achieve improved transmission of axial forces by the swivel joint, the invention provides that a bearing element () for absorbing forces in the direction of the axes of the second shaft () and the roll () is arranged between the wobbler () and the spindle head (), such that a push rod () for transmitting axial forces between the wobbler () and the spindle head () is arranged between the two bearing elements ().
