    • 专利摘要:
    The invention relates to the construction of rolling mills. The purpose of the invention is the expansion of the use and performance. The hollow piston 2 has pockets 10, which on one side communicate with a pressure chamber, and on the other through throttle holes 8, with pockets 7 support shoes 4. The support has at least two support shoes 4 that can move independently of each other in the direction of the unlocked surface of the roll . The working fluid enters the pressure chamber, and then into the pockets of the 10 pistons and 9 support shoes. As a consequence, the support shoes are pressed against the mating surface of the roll. The working fluid enters the pockets through the throttle orifices and support shoes, due to the resulting back pressure, detached from the mating surface, providing a non-contact support. 1 il.

    专利说明:

    The invention relates to rolling production, specifically to the structures of the supports of mill rolls.
    The purpose of the invention is to expand the field of use and increase working efficiency by ensuring self-adjustability of the support when the roll diameter changes due to regrindings.
    The drawing shows a hydrostatic support circuit.
    The hydrostatic support consists of a housing 1 in which a hollow piston 2 is placed so that a pressure chamber is formed between the bottom of the core and the piston, which is filled through the opening 3 with the working fluid. The hollow piston has at least two support shoes 4 and 5 in contact with the working surface 6 of the rolling roll. In both shoes there are pockets 7 connected by means of throttle channels 8 to the pressure chamber. The two adjacent support shoes are movable relative to each other and independently from each other in the direction of said roll surface. The support shoes have sealing rings 9 and, due to the rounded execution of the outer edges of the piston, they can be tilted or folded in relation to them and thus in relation to each other and independently from each other along the axis of the piston 2.
    Hydrostatic bearing works as follows.
    The working fluid enters the pressure chamber, and the sieve enters the pockets of 10 support shoes, as a result of which the support shoes are pressed against the mating surface of the roll. Since the working fluid enters the pockets through the throttle openings, the support shoes due to the semi-counter pressure of the back pressure are detached from the mating surface and provide a non-contact support, with ETOM, the support shoes within certain limits follow the roll surface movements so that on the distance and inclination of the supported surface. Since the support shoes can tilt independently of each other, it is possible for them to be self-adjustable relative to the supported surface as it changes.

    curvature, distortion or tilt of the working surface of the roll, as well as changes in diameter as a result of regrinding.
    The self-repositionability to these changes of the roll surface supported is achieved in a larger range, since the support includes at least two independent support surfaces, each of which allows for a large change in curvature and skewness.
    To prevent uncontrolled tilting or tilting of the support shoes, they can be connected to each other by means of a hinge, elastic or flexible intermediate piece 11, in addition, the support shoes can be supported by a ball joint.
    The support can be made with more than two support shoes, for example, three or five, placed one after another around the circumference of the supported surface, due to which a further increase in self-adjustability is achieved, while the average support shoe can be fixed in place, and can be moved only external support shoes can be made.

    Invention Formula
    Hydrostatic support mainly for rolls of a rolling mill, containing a pressure chamber filled with a working fluid, in which a hollow piston is placed, carrying a movable support shoe with pockets connected through throttle channels with a pressure chamber, the support shoe contacting the curvilinear surface of the rolling roll, about t - characterized by the fact that, in order to expand the area of use and increase efficiency by ensuring its self-alignment when changing the diameter of the roll, caused by regrinding Kami, the hollow piston is provided with at least one additional support Shoe, while both adjacent Shoe is made with the ability to move relative to each other and independently from each other in the direction of the specified surface of the roll.
