ROLLING ROLL BEARING ASSEMBLY

摘要

FIELD: rolling equipment, namely bearing assemblies of rolling rolls. ^ SUBSTANCE: bearing assembly of rolling roll includes liquid friction bearing unit whose sleeve-pivot is fit on cone portion of rolling roll journal. Said sleeve-pivot is joined with roll journal by means of one or more keys placed in key grooves formed on sleeve-pivot and cone journal of roll. Base of each key groove is parallel to generatrix of joined cone surfaces of sleeve-union and roll journal. ^ EFFECT: increased rigidity of rolling roll bearing unit, lowered influence of rolling roll bending upon accuracy of rolled metal at time moment of key joint passing through load plane. ^ 2 dwg
