【発明の名称】圧延機のスタンド内でロールを軸方向に移動させるための装置
Document Type and Number:
Japanese Patent JP2747029
Kind Code:
B2
Abstract:
In the hitherto known devices, the axial shifting of rolls in the stand of a rolling mill is carried out on slideways, the sliding friction resistances of the hydraulic shifting machinery arranged externally on the roll stand which occur in the slideways having to be overcome by increased energy consumption. In addition, these roll-shifting devices are of complicated structure and are hard to get at and difficult to maintain owing to the pressure and lever elements which are arranged externally on the roll stand and project a long way outwards. According to the invention, these disadvantages are eliminated in a simple way by the fact that the inner bearing ring (5), fastened to the bearing journal (2) of the roll (1), of the radial bearing (3) in the form of a roller bearing is arranged so as to be axially moveable with respect to the outer bearing ring (7, 8) of the radial bearing (3), and that the shifting system is integrated in the axial bearing (4) as a hydraulic pressure system (16, 20, 22, 23).
