CANTILEVER ROLL ASSEMBLY Russian patent published in 2001 - IPC

FIELD: cantilever type roll, for example annular roll mounted on edge of drive shaft of roll of rolling mill stand. SUBSTANCE: roll assembly includes holding shaft with cone section passing from edge of bead to end section. Annular roll with inner and outer ends and cylindrical opening is axially mounted on said shaft in such a way that its inner end rests upon edge of bead and its cylindrical opening embraces cone section of shaft. Cone sleeve is mounted between cone section of shaft and cylindrical opening of roll. Cylindrical holder is axially mounted on end section of shaft and fixed with possibility of rotation together with said section. Nut is screwed onto end section of shaft in such a way that cone sleeve is forced between cone section of shaft and cylindrical opening of roll for centering roll on shaft through holder. Threaded members may be screwed on through holder for axial joining with outer end of roll due to forcing inner end of roll to bead edge. Cone sleeve may be used as centering device. Torque is transferred from shaft to roll by other components of roll assembly frictionally engaged with roll ends. It reduces pressure upon roll rim, allows to decrease thickness of roll and to increase diameter of roll. EFFECT: simplified design. 9 cl, 5 dwg
