Abstract
In order, in a guide roller for continuous-casting plants, which is formed by a plurality of aligned roller portions, to avoid the creeping movements of the guide roller in the axial direction and thermally induced distortions in it, it is proposed that a roller portion adjacent on both sides of roller portions either be provided at its two ends with roller journals carrying support bearings, and these roller journals engage into recesses of the adjacent roller portions, or be provided at its two ends with recesses, and roller journals, having support bearings, of the adjacent roller portions engage into these recesses.
Claims11
A guide roller for continuous casting plants, the guide roller being rotatable about an axis of rotation and comprising:
- a central roller portion having symmetrical axially opposite first and second ends;
- two side roller portions coaxially located at opposite ends of the central roller portion, each of the side roller portions having a first end adjacent to one end of the central roller portion, and axially opposite second end;
- a non-rotatable joint between the central roller portion and the first end of each of the side roller portions, each non-rotatable joint being comprised of:
- a recess at the end of one of the joined roller portions;
- an axial projection of reduced cross section at the end of the other of the joined roller portions that fits into the recess;
- and
- locking devices operative to prevent relative axial and rotational displacement of the side and central roller portions with respect to one another;
- first and second rotatable joints between the roller and a fixed support, the rotatable joints being comprised of respective first and second rotational bearings mounted on the fixed support and on the axial projections;
- and
- first and second further rotatable joints between the side roller portions and the fixed support, the further rotatable joints being located at the second ends of the side roller portions.
