Example Embodiment

[0030] exist figure 1 A rolling device 100 , which is used, for example, in metallurgical technology, has rolls with roll bodies 11 and at least one cylindrical roll neck 10 . The roll neck 10 is mounted non-rotatably and with radial play in a receiving hole of the roll neck bush 20, which is complementary to the roll neck 10 and has a cylindrical shape. The radial gap between the roll neck bush 20 and the roll neck 10 is formed by a cavity 12 that is rotationally symmetrical or surrounds the roll neck 10 . The roll neck bushing 20 can easily be pushed onto the roll neck 10 or conversely into the roll neck bushing 20 through the radial gap. The radial play, which is the difference in diameter between the roll neck bush 20 and the roll neck 10 , is preferably in the range between 0.10 mm and 0.80 mm at most.

[0031] The wall thickness d of the cylindrical roll neck bush is between 10 mm and 75 mm without taking into account the optional rotationally symmetrical concave prof...

Abstract

The invention relates to a roll arrangement (100) for use in metallurgical technology, comprising a roll that has a roll barrel (11) and two roll necks (10), and at least one neck bushing (20) for accommodating at least one of the roll necks (10) in a rotationally fixed manner. A dog element (25) that functions as a form-locking rotationally fixed connection is arranged between the roll neck (10) and the neck bushing (20). In order to increase the load-bearing capacity of the roll bearing without increasing the size of or the mounting space for the roll bearing and at the same time ensure easy assembly, the roll neck (10) is mounted in the neck bushing (20) with some radial play such that a circumferential cavity (12) is formed between the neck bushing (20) and the roll neck (10) in the unloaded state as a result of the radial play. In order to increase the size of the cavity (12), the roll neck (10) or the inner surface (21) of the neck bushing (20) additionally has a concave contour (50) or profile.

Description

technical field [0001] The invention relates to a rolling installation in metallurgical technology having a roll with a roll barrel and two roll necks and at least one roll neck bushing for receiving at least one of the roll necks in a non-rotatable manner , wherein the peripheral surface of the roll neck and the inner peripheral surface of the roll neck bushing are configured in a cylindrical shape complementary to each other, and a transmission element is arranged between the roll neck bushing and the roll neck as a form fit non-rotatable connections. Background technique [0002] Rolling installations are known from the prior art in which roll necks are accommodated in cylindrical or conical roll neck bushings. In order to transmit the circumferential force, a transmission element is arranged between the roll neck bushing and the roll neck. [0003] For example, oil film bearings are used in rolling mills for supporting back-up rolls that receive rolling force from adju...
