Disclosed is a support roll for a rolling mill, such as a plate rolling mill, flat rolling mill, or similar, comprising a jacket and a roll shaft which is embodied in several parts. The invention also relates to a method for producing a support roll.

Method for producing a support roll for a rolling mill

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 (&#x3b1;) 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 ().

Drive spindle for the main drive of a roll stand

An overload safety coupling, especially for the main drivetrains on rolling stands, which bridges a toothed spindle section and a spindle section with a permanent seat. The coupling includes a rotating-and-sliding sleeve, which has internal toothing at one end to hold the spindle section in a way that allows axial displacement. At the other end, the sleeve holds an inner sleeve, which is permanently seated on the spindle section. A pressure sleeve and a pressure gap pretensioned with pressure fluid produce a nonrotatable connection between the rear sleeve-like extension and the inner sleeve, which frictional connection gives way in the event of an overload.
