Изобретение относитс к прокатному производству .This invention relates to rolling production.
Известен бандажирован«ый валок, состо щий из бандажа и ПОлой оси со сквозным продольным пазом по всей длине.Known was the shank roller consisting of the shroud and the Poley axis with a through longitudinal groove along the entire length.
Однако такой прокатный валок не обеспечивает необходимую точность прокатки и срок службы валка.However, such a mill roll does not provide the necessary rolling accuracy and roll life.
Цель изобретени - увеличение жесткости валка и повышение надежности креплени баидажа.The purpose of the invention is to increase the stiffness of the roll and increase the reliability of fastening the baidage.
Это достигаетс тем, что на полой оси выполнены по крайней мере три сквозных параллельных продольных паза, расположенных на равных рассто ни х один от другого и наход щихс на среднем участке оси между :посадочными местами дл подшипников.This is achieved by the fact that at least three through parallel longitudinal grooves are made on the hollow axis, spaced at equal distances from one another, and located in the middle section of the axis between: the bearing seats.
На чертеже изображен прокатный валок, общий вид.The drawing shows the mill roll, General view.
Прокатный валок включает /в себ бандаж 1, ось 2 валка со сквозным отверстием 3. На оси 2 выполнены три сквозных параллельныхThe mill roll includes / is in band 1, an axis 2 is a roll with a through hole 3. On the axis 2, there are three parallel through holes
продольных паза 4 по всей длине участка, размещенного между посадочными местами подшипников 5.longitudinal groove 4 along the entire length of the section placed between the bearing seats 5.
В процессе .прокатки металла валок нагреваетс неравномерно: бочка валка нагреваетс и расшир етс значительно больше, чем ось. Но так как ось находитс в упрутосжатом состо нии, то Недостаточное тепловое расширение оси компенсируетс ее упругим расширением , и этим обеспечиваетс посто нство нат га между бочкой валка и упругой осью, что предотвращает проворачивание бочки на оси.In the process of rolling a metal, the roll is heated unevenly: the roll barrel heats up and expands significantly more than the axis. But since the axis is in an elastically compressed state, the insufficient thermal expansion of the axis is compensated for by its elastic expansion, and this ensures a constant tension between the roll barrel and the elastic axis, which prevents the barrel from turning on the axis.
