Roll arrangement

摘要

The invention relates to a roll arrangement 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 without a clearance in a rotationally fixed manner. In order to increase the load-bearing capacity of the roll bearing without increasing the size of or the mounting space for the roll arrangement, a circumferential cavity is formed between the neck bushing (20) and the roll neck (10) in the unloaded state of the roll arrangement.

主权项

1. A roll arrangement (100) for use in metallurgy, comprising a roll having a roll barrel (11) and two roll necks (10);
at least one neck bushing (20) for receiving at least one roll neck (10) for joint rotation therewith and without a radial clearance, characterized in that in an unloaded condition, a circumferential rotationally symmetrical hollow space (12) is formed between the neck bushing (20) and the roll neck (10) at least in partial region therebetween, and the hollow space (12) is limited, viewed in a longitudinal direction of the roll arrangement (100), by a rotationally symmetrical concave shape of the outer surface (13) of the roll neck (10) and/or of the inner surface (21) of the neck bushing.
