Abstract
A roll assembly for a rolling-mill stand has a pair of axis-defining, coaxial, and axially spaced journals, respective roll supports carried in the journals and rotatable therein about the axis, and a roll ring engaged between the supports. The roll supports are each formed with a pair of radially spaced and separate annular surfaces both centered on the axis and the surfaces of one support are directed at least generally axially toward the other roll support. At least one of the surfaces of each pair is substantially frustoconical and forms with the axis a different angle from the other of the surfaces of the pair. One of the supports is formed at the axis with an axially extending passage and the roll ring is formed with generally axially oppositely directed pairs of annular surfaces respectively complementary to and flatly engaging the annular surfaces of the roll supports. An extension stem axially fixed to the other of the supports extends with radial play through the passage and is provided with a nut or the like bearing on the one element, normally the service-side element, for pulling the two support elements axially toward each other and thereby axially compressing the roll ring between the annular surfaces of the roll supports.
