ABSTRACT:
Where oil film bearings are used on rolling mill rolls provided with conical roll necks, the bearing bush being interference fitted to the roll neck to rotate along with the roll neck, adhesive friction may cause contact corrosion between the bearing bush and the roll neck. To prevent such detriment, the oil grooves are machined slopingly into the conical inner surface of the rotating bearing bush in order to permit creep oil issuing from the oil grooves during operation to spread over ungrooved rotational partial surfaces by the effect of the centrifugal force. The lubricating oil is supplied to the oil grooves through bores distributed on the circumference of the bush by contact with the compressed oil film present between the cylindrical outside surface of the rotating bearing bush and the fixed bearing bush on the roll chock.
