FIELD: three-roll rolling stand, possibly finish stands of sizing and reducing mills where roll load is slightly less than in rough rolling stands, calibrating mills.
SUBSTANCE: three-roll working stand for lengthwise rolling with adjustable roll gap and with one inlet shaft includes housing where three roll units mutually joined through cone gear wheels not changing their position during roll gap adjustment are mounted. Simultaneous adjustment of all rolls is realized due to rotation of eccentric sleeves by means of their rotation drive mechanism. Each cone gear wheel is mounted in housing of stand in rolling bearing assemblies. Drive shafts of rolls are hollow ones and they are provided with internal teeth.
EFFECT: improved operational efficiency of stand, simplified adjustment of roll gap.
