摘要:
A device for adjusting a brush roll relative to a work roll in roll stand, particularly a roll stand for hot-rolling of aluminum includes pivotable supports mounted on both sides of the brush roll. The brush roll is rotatable in a direction opposite the direction of rotation of the work roll. The brush roll is displaceable in translatory movements parallel to the work roll. The pivot bearing of each brush roll support is arranged on a work roll chock, wherein the support includes a pivoting lever which is located between a controllable actuating element and a restoring support element. The actuating element is mounted in the balancing block or bending block of the roll stand and the support element is mounted in the chock.

The invention relates to a rolling device (1) comprising at least two working rolls (2, 3) which are respectively mounted in a roll stand (6) by means of working roll assembly pieces (4, 5). At least one of the working rolls (2, 3) is adjustable relative to the other working roll (2, 3) within the roll stand (6), especially in a vertical direction, so as to adjust a desired rolling gap. At east one working roll (2, 3) is effectively connected to bending means (7), with the aid of which said working roll (2, 3) can be impinged upon by a bending moment. The working roll assembly piece (4, 5) is provided with arms (9, 10) that laterally protrude relative to the axis (8) of the working roll (2, 3) to absorb the force generated by the bending means (7). In order to improve the adjustability of the rolling device to a large ascent, a pressure-transmitting element (12) which can be displaced relative to the roll stand (6), particularly in a vertical direction, is disposed between a pressure-generating element (11) of the bending means (7), especially a piston, and the protruding arm (9, 10) of the working roll assembly piece (4, 5).

The invention relates to an overload security coupling, in particular for main drivetrains on rolling stands, forming a bridge between a toothed spindle section (1) and a spindle section (6), with an interference fit. According to the invention, the security coupling for axial overload may be combined with a rotational fixing against torsional overload, whereby the same is embodied with a rotating sliding sleeve (3), housing the spindle section (1) with internal toothing in an axially-displaceable manner at one end and enclosing the spindle section (6) with an inner sleeve (4) in the interference fit at the other end and the rear sleeve-like projection (13) thereof generates a fixed functional connection which gives way in case of overload with a pressure sleeve (5) and a pressure gap (14), tensioned by pressure medium. In order to combine the security coupling of axial overload with a rotational fixing of torsional overload, the spindle section (1) is embodied with a fixed beating point (2) and the spindle section (6) is embodied with a movable bearing point (8).

The invention concerns a drive spindle (1) 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, especially to a multiple spline profile, and a second shaft (5) for transmitting the torque from the coupling element, especially the multiple spline profile, 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 (α) between the axis of rotation (10) of the roll (6) and the axis of rotation (11) of the second shaft (5). In order to achieve improved transmission of axial forces by the swivel joint, the invention provides that 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).

摘要:
Rolling device with two work rolls supported in a rolling stand by a chock and with at least two additional rolls supported in the rolling stand by an additional chock. At least one of the work rolls and at least one of the additional rolls is adjustable for adjusting a desired roll gap relative to the other work roll or relative to the other additional roll. The work rolls have axial shifting devices for axial shifting and holding the work rolls into a desired axial position relative to the rolling stand. The work rolls are operatively connected with bending devices, by which a bending moment can act on the work rolls. The axial shifting devices are arranged and act between the rolling stand and the work roll locking mechanism. The bending devices are arranged or act between the work roll chock and the chock of the additional roll.
