ABSTRACT:
The invention relates to a taper journal bearing for rolls, used in rolling mills. The bearing includes a bushing installed in a roll bearing box, a sleeve closely fitted onto a taper journal of the roll, for supporting a load thereof, an oil film deposited between the bushing and the sleeve, and means for attaching the sleeve to the roll at an area other than that directly subjected to a rolling force. The invention eliminates the increased variation in the reduction force taking place at each rotation of the roll, due to a deformation of the sleeve. The latter is caused by a clearance at a keyway formed in the sleeve, for a key arranged between the sleeve and the taper journal.
