    The invention relates to equipment used in the processing of pressure roll materials, and may find application in the pulp and paper industry.
    Known shafts for pressure treatment of 5 roll materials containing a jacket, a core and seals, forming in the annular cavity between the jacket and the core a chamber for the working fluid [1].
    However, during shaft operation, especially at high speeds, part of the working fluid from the pressure chamber, due to leaks in the seals, passes into the chamber with air, which: violates the pressing mode of the web And increases the power consumption of the shaft drive. u
    The purpose of the invention is the reduction of power consumption for shaft drive.
    This is achieved by the fact that the shaft has a plate fixed to the core along the entire length of the shaft 20 at an angle to its inner surface, and channels are made in the core, the outlet openings of which are located against the inner side of the plate. In this case, the plate can be installed at an acute or obtuse angle to the direction of rotation of the shirt at the point of contact with the inner surface of the shirt, and the plate can be made of epoxy resin reinforced with fiberglass.
    In FIG. 1 shows the installation option! Of the plate in the lower part of the shaft; in FIG. 2 - node mounting plate; in FIG. 3 is a diagram of the installation of the plate in the upper part of the shaft; in FIG. 4 is a diagram of the installation of two sealing plates; in FIG. 5 - plate made in the form of a squeegee.
    The shaft contains a core 1 and a shirt 2, in the annular space between the cat’s there are chambers 3 with working fluid. The shaft has two plates 4 forming a chamber 3. A shaft 5 is pressed against the jacket 2, which presses the web. The core 1 is riveted using, for example, a screw 6, a sealing plate 7, touching the inner surface of the shirt 2..
    Inside the shaft can be installed one sealing plate 7 (Fig. 1, 3, 5) or two plates (Fig. 4). The sealing plate 7 can be located both under an acute angle and at an obtuse angle with respect to the direction of rotation of the logger at the point of contact with the inner surface of the shirt. The plate can be made of fiberglass reinforced epoxy.
    In the shaft core, channels 8 are made for supplying the working fluid under pressure to the chamber 3 and channels 9 for draining the working fluid from the air cavity 10 penetrating there during the shaft operation.
    The plate 7 may be made in the form of a squeegee collecting working fluid from the inner surface of the shirt 2 (Fig. 5).
    During shaft operation, a working fluid is supplied under pressure to the chamber, which ensures shaft inflexibility. When the shirt 2 rotates, part of the working fluid from the chamber 3 through the seals 4 penetrates into the air chamber 10, which on the one hand violates the pressing mode, and on the other hand increases the shaft rotation power due to increased fluid friction. Due to the presence of the sealing plate 7, the penetrated working fluid either falls under it (Fig. 1, 3, 4), or is scraped off from the inner surface of the jacket 2, from where it enters the outlet channel 9.

    (54) ROLLER PRESSURE SHIPPING SHAFT I2 The invention lends itself to equipment used in the pressurizing of rolled materials, and can be used in the pulping and paper industry. Shafts for processing pressurized roll materials are known that contain a jacket, a core, and seals, forming in the annular cavity between the jacket and the core a fluid chamber enters the chamber with air, which violates the mode of pressing the web and increases the power consumption of the shaft drive. The circuit of the invention reduces the power consumption of the shaft drive. This is achieved by having the shaft Astine is attached to the core along the entire length of the cutter at an angle to its inner surface, with channels in the core that have outlet openings located against the inner side of the plate. At the same time, the plate can be set at a sharp angle to the direction of rotation of the rupapsi touching it with the inner surface of the jacket, and the plate can be made of fiberglass-reinforced epoxy. FIG. 1 shows a variant of mounting the plate in the lower part of the shaft; in fig. 2 - plate attachment unit; in fig. 3 is a diagram of the installation plate in the upper part of the shaft; in fig. 4 is a diagram of the installation of two sealing plates; in fig. 5 - plate, made in the form of a squeegee. The shaft contains a core 1 and a shirt 2, in the annular space between which there are chambers 3 with working fluid. The shaft has two plates 4, forming the chamber 3. The shaft 5 is pressed against the shirt 2, which is pressing the web. To the core 1 is attached with, for example, a screw 6, a sealing plate 7 touching the inner surface of the jacket 2. A single sealing plate 7 (Fig. 1, 3, 5) or two plates (Fig. 4) can be installed inside the shaft. . The sealing plate 7 can be located both at a sharp and obtuse angle to the direction of rotation at the point of its contact with the inner surface of the jacket. The plate can be made of fiberglass-reinforced zpoxy resin. In the heart shape of the shaft, the channels 8 are provided for supplying the working fluid under pressure in the chamber 3 and the channels 9 for draining the working fluid from the air cavity 10 penetrating the shaft. Plate 7 can be made in the form of a squeegee, collecting the working fluid from the inside; the surface of the jacket 2 (Fig. 5). When the shaft is in operation, the working fluid is supplied under pressure into the chamber, which ensures the shaft is unbending. When the jacket 2 is rotated, part of the working fluid from chamber 3 through seals 4 penetrates into the air chamber 10, which; on the one hand, it violates the mode of the stress of the vania, and on the other hand, it increases the power of rotation of the shaft due to the increased friction of the liquid. Due to the presence of the sealing plate 7, the penetrating working fluid falls either under it (Fig. 1, 3, 4), or the internal surface of the jacket 2 is scraped off, from where it enters the tapping channel 9. Invention 1. The shaft for pressure treatment of roll materials containing a jacket, a core, and seals forming a chamber for the working fluid in the annular cavity between the jacket and the core, characterized in that, in order to reduce power consumption for the shaft drive, it has a plate attached to the core along the entire length of the jacket scrap to its inner surface, and in the core there are channels, the outlet openings of which are located against the inner side of the plate.
