    专利说明:

    The invention relates to metallurgy and can be used in the rolling industry.
    The aim of the invention is to simplify the manufacture of the roll.
    The drawing shows a roll device (the upper half is a longitudinal section, and the lower half is a side view).
    Shaft 1 forms or bears a flange 2 fixed firmly on the shaft, which, as a support ring on one side, forms a support for stress voltage and can be made monolithically with the shaft, but not necessarily. Stream gauges 3 with intermediate clamping rings 4 are mounted on v.n. 1,
    On the other side, the shaft is provided with a thread 5, on which a nut 6 sits, in which a hydraulic device is installed, in a pre-tensioning roll.
    The nut 6 comprises an annular piston 7. which through pipes 8 can be loaded with hydraulic medium. In addition, the nut 6 contains outside and on its end side rotated to the installation of the ring 4, a bore 9 in which there is a compensating ring 10. Both the hydraulic power clamp and the compensating ring are located compactly in the plane of the longitudinal section of the nut 6, the shape of the elements involved , in particular, also of the adjacent intermediate ring 4, which is affected by the power clamping device and the compensating ring, is very simple. The interacting end surfaces 11 of the nut 6 and the compensating rings 10 are serrated with a very small lateral slope. Side must be very small, t, e. well below the self-braking limit, s, so that the clamping device, through the force acting on the clamping ring, cannot be loosened. In extreme cases, it is advisable to choose the direction of the slope
    in order to increase the axial stress when the compensating ring 10 relative to the ring 6 is rotated by the drive torque, the interacting surfaces between the ring 10 and the ring 4 can be made toothed with the same small lateral slope and obtain the same effect.
    For tightening the brook 3 and the rings 4, the nut 6 is twisted as tightly as possible, so that only a minor axial pressing of the installation of the brook 3 can be expected; the ring 4 should be expected under the action of the force clamping device. If thereafter the annular piston 7 is loaded with hydraulic fluid, the shaft is expanded. Due to this, the shaft weakens and an axial clearance arises. Then, the compensating ring 10 is rotated in the direction of the arrow firmly back into a tight fit in the mounting unit, as a result of which, after loosening the power clamp, the tension setting state of the skid remains fixed and the working clamping force is maintained. It is by turning the compensating ring that the relative area on which the toothed side surfaces 11 of the compensating ring 10 and the nuts b interact, is reduced, the device allows the transfer of large axial forces evenly around the circumference of the shaft.

    Claims (1)
    [1]
    Claims of the invention A roll device comprising a shaft with a collar, ribbed gangs with clamping rings fixed by a nut, in which a hydraulic device is installed to create a pre-stress in the roll and a compensating ring in contact with the clamping ring with a nut with different themes. that, in order to simplify the manufacture of the roll, the end surfaces of the compensating ring and the nut or the compensating ring and the clamping ring, which are in contact with each other, are jagged with an angle of inclination of the tooth surface smaller than the angle of self-locking.
