As shown in fig. 1-2, the water-cooled rotating device for the aluminum strip roll type casting roll in the present embodiment is used for being installed on the non-transmission side of the casting roll to provide a circulating channel for cooling water in the casting roll, and at least comprises a shaft core 1, a shaft sleeve 2, a sealing ring 3, a sealing ring 4, a spacer ring 5, a bearing 6 and an end cover 7. The shaft core 1 is divided into a front section area, a middle section area and a rear section area, a progressive stepped shaft design is adopted between each section, and at least two water cooling channels 10 are arranged in the progressive stepped shaft design and are respectively used for water inlet and water return; the shaft sleeve 2 is rotatably arranged on the shaft core 1, the shaft sleeve 2 is composed of two sections of separated sleeve bodies, the inner walls of the end sides of the two sections of sleeve bodies, which are away from each other, are provided with progressive stepped shafts which are tightly matched with the shaft core 1 and are used for sequentially arranging a sealing ring 4, a sealing ring 3 and a substituted cylindrical hole of a bearing 6 between the sleeve bodies and the shaft core 1, a spacing ring 5 is arranged between the two sections of sleeve bodies, the sealing ring 3 and the sealing ring 4 are symmetrically arranged on two sides of the spacing ring 5, and at least one water nozzle 13 is respectively arranged on the two sections of sleeve bodies and is respectively communicated with a water cooling channel for water inlet of the shaft core 1 and a water cooling channel for water return; the sealing ring 3 and the sealing ring 4 are both arranged on the shaft sleeve 2 and are tightly matched with corresponding stepped sections of the shaft core 1; the spacing ring 5 is tightly abutted on the left and right sleeve bodies, and is separated by the step of the spacing ring 5 and is tightly pressed on the sealing ring 3; the end cover 7 is arranged on the shaft sleeve 2 and is pressed on the bearing 6; the sealing ring 3 adopts a pressure-resistant and high-temperature-resistant J-shaped framework structure; the sealing ring adopts a high-temperature-resistant O-shaped structure; the two end sleeves are detachably and fixedly connected through a long screw 12, and the long screw penetrates through one end cover 7 to form a fixed structure. According to the scheme, the progressive stepped shaft sectional seal is adopted, progressive pressure relief and alternate-feeding type fusion are adopted, and the pressure-resistant and high-temperature-resistant sealing structure is matched, so that the sealing and rotating requirements can be effectively and rapidly met, the problems of leakage and poor water supply efficiency can be effectively solved, and the novel water-cooling rotating device can be suitable for the requirements of casting rolls in high-speed roll casting production of high-strength aluminum alloy thin strips, and also can be suitable for the requirements of casting rolls in medium-low-speed thick strip roll casting production, and particularly can be suitable for the requirements of casting rolls in high-strength alloy high-speed thin strip roll casting production.
The water cooling channel 10 in the embodiment consists of a blind hole channel axially formed along the shaft core 1 and a radial hole for punching the blind hole channel along the radial direction of the shaft core 1; and the inner walls of the two sections of sleeve bodies of the shaft sleeve 2 are respectively provided with a groove 11 which is respectively communicated with the radial hole of the water cooling channel for water inflow and the radial hole of the water cooling channel for water return of the shaft core 1, and the grooves 11 are communicated with the water nozzle 13 opposite to the grooves.

The shaft core in another embodiment is provided at the end facing away from the casting roll with a pressure plate 8 penetrated by the connecting screw and intended to abut against the bearing 6, which pressure plate has a rim structure, so that the bearing is arranged on the pressure plate instead of on the shaft core, which can likewise achieve the purpose of the shaft core rotating with the casting roll, and the rim of the pressure plate can also be used to abut against the bearing, making its structure more rational and reliable. In addition, the arrangement of the pressing plate can ensure that the pore canal of the shaft core penetrated by the connecting screw does not need to be processed with internal threads, and only the internal threads matched with the connecting screw are required to be arranged on the pressing plate, so that the processing cost and the processing difficulty can be reduced.
