Известен прокатный валок, состо щий из бандажа и полой осп.A mill roll consisting of band and hollow smallpox is known.

Однако в известных конструкци х бандажированпых валков не исключаетс , особенно в услови х гор чей прокатки, возможность проворота бандажа вокруг несущей оси. Кроме того, выполнение элементов дл  надежного соединени  оси с бандажом при изготовлении последнего из твердых сплавов требует трудоемкой механической обработки.However, in the known structures of the bandaged rolls, it is not excluded, especially under the conditions of hot rolling, the possibility of turning the bandage around the bearing axis. In addition, the implementation of elements for a reliable connection of the axis with the bandage in the manufacture of the latter from hard alloys requires time-consuming mechanical processing.

Цель изобретени  - обеспечение надежного креплени  бандажа на оси.The purpose of the invention is to provide a reliable fastening of the tire on the axle.

Цель достигаетс  тем, что ось выполнена со сквозным продольным пазом по всей длине.The goal is achieved by the fact that the axis is made with a through longitudinal groove along the entire length.

На фиг. 1 изображен предложенный валок в сборе; на фиг. 2 - то же, поперечное сечение; на фиг. 3 - то же, продольное сечение .FIG. 1 depicts the proposed roller assembly; in fig. 2 - the same cross section; in fig. 3 - the same longitudinal section.

При прокатке элементы валка (несуща  ось и бандаж) нагреваютс  неравномерно: бандаж 1 нагреваетс  больще, чем несуща  ось 2.When rolling, the elements of the roll (bearing axle and bandage) are unevenly heated: bandage 1 is heated more than the carrier axle 2.

Однако разрезанна  ось, наход сь в упруго-сжатом состо нии, компенсирует недостаток теплового относительно бандажа расщиренн  упругим расширением, чем обеспечиваетс  посто нна  величина требуемого соединени  бандажа с осью.However, the cut axis, which is in an elastically compressed state, compensates for the lack of heat relative to the bandage extended by elastic expansion, which ensures a constant value of the required connection of the bandage to the axis.
