Description

ОПОРА РАБОЧЕГО ВАЛКА ПРОКАТНОЙ КЛЕТИSUPPORT OF THE WORKING ROLLER OF THE ROLLED STYLE

Известны опоры рабочего валка прокатной клети, содержащие подшипник жидкостного трени , выполненный в виде втулкивкладыша , установленной в поворотной эксцентриковой втулке, снабженной приводом поворота (регулировки раствора валков).Known support work roll rolling stands, containing the bearing of the liquid friction, made in the form of a sleeve liner installed in a rotary eccentric sleeve, provided with a rotating drive (adjusting the solution rolls).

Предлагаема  опора отличаетс  от известных тем, что втулка-вкладыш фиксирована от проворота с помошью выступа на крышке подшипника, вход щего в паз на торце втулки-вкладыша .The proposed support differs from the known ones in that the insert bush is fixed from rotation by means of a protrusion on the bearing cap entering the groove on the end of the insert bush.

Это позвол ет уменьшить необходимый эксцентриситет и улучшить услови  работы подшипника благодар  стабилизации углового положени  зоны нагружени  втулки-вкладыша .This makes it possible to reduce the required eccentricity and to improve the working conditions of the bearing due to the stabilization of the angular position of the loading zone of the liner.

На чертеже схематично изображена предлагаема  опора рабочего валка прокатной клети, разрез.The drawing schematically shows the proposed support of the work roll of the rolling stand, section.

Цапфа / валка с промежуточным стаканом 2 расположена во втулке-вкладыше 3, котора  свободно установлена в эксцентриковой втулке 4, имеюшей привод 5 ее поворота. Эксцентрикова  втулка установлена в свою очередь в подушке 6.The trunnion / roll with the intermediate cup 2 is located in the sleeve insert 3, which is freely installed in the eccentric sleeve 4 having the drive 5 of its rotation. The eccentric sleeve is installed in turn in the cushion 6.

о, который входит в лаз на торце втулкивкладыша 3 и фиксирует ее от проворота.o, which enters the hole at the end of the sleeve of the liner 3 and fixes it against rotation.

Фиксаци  втулки-вкладыша 3 позвол ет поворачивать эксцентриковую втулку на 180°,Fixing the liner sleeve 3 allows the eccentric sleeve to be rotated 180 °,

5 т. е. полностью использовать эксцентриситет при регулировке раствора валков, что дает возможность уменьшить величину эксцентриситета при сохранении диапазона регулировки , при этом услови  работы втулки-вклады10 ша не нарушаютс .5 i.e., the eccentricity is fully utilized when adjusting the roll solution, which makes it possible to reduce the eccentricity while maintaining the adjustment range, while the working conditions of the sleeve inserts 10 are not violated.
