Abstract
A hydrodynamically lubricated assembly is disclosed for adjustably and rotatably supporting the journals of work roll pairs in the housing of a roll stand in a rolling mill. The assembly includes a pair of eccentric sleeves journalled for rotation in the housing. Inner sleeves containing journal bearings are rotatably received in the eccentric sleeves, and the work roll journals are rotatably received in the journal bearings. Hydrodynamic and optionally also hydrostatic fluid supply networks communicate with the journal/bearing interfaces via radial conduits in the inner sleeves and journal bearings. The inner sleeves are anchored against rotation, and the eccentric sleeves are rotatable to adjust the parting between the work rolls.
