    (54) SHAFT WITH GUTTER AND METHOD OF ITS MANUFACTURE
    one
    The invention relates to the manufacture of rolls with grooves and can be used, for example, in the paper industry in the manufacture of aggregates for the dewatering of paper webs.
    The shafts with grooves used in these units have a diameter of up to 1 m, and a length of up to 10 m. The working surface of such shafts is made of stainless steel, and therefore cutting through the grooves presents great difficulties.
    Famous shaft with a groove, made in the form of a cylindrical shaft fixed on its surface along a helix with a given step of at least one strip 1.
    A known method of manufacturing a shaft with a groove, in which at least one strip is wound onto a cylindrical shaft along a helical line with a predetermined pitch 1.
    However, the design of the known shaft and the method of its manufacture do not provide sufficient accuracy and strength properties of the product.
    In order to increase manufacturing accuracy and strength properties, a known shaft with a groove is equipped with at least one
    a rod placed at a given distance from the surface of the cylindrical shaft between the turns of the strip and fixing the distance between them. The strip, Iawita on a cylindrical shaft, provided with longitudinal grooves, made with. both its sides in accordance with the number of bars and their placement, while the diameter of the bars is greater than the sum of the depths of these grooves by the step size between the turns of the strip.
    The coils of the band are tightly connected to the net.
    For the same purpose, in a known method of manufacturing a shaft with a groove between the turns of a strip, at the same time as winding it, at least one bar is wound at a predetermined distance from the surface of the shaft, fixing the distance between the turns of the strip and connected to the strip.
    Before winding on the surface of the strips, grooves are made in accordance with the number and placement of the rods.
    The coils of the strip are welded with rods. The coils of the strip are welded to the rods by spot welding with a certain pitch. The coils of the band are soldered with rods. The coils of the strip are glued to the rods.
    FIG. 1 shows a shaft, a general view; in fig. 2 - embodiments of the shaft; in fig. 3 — apparatus for manufacturing a shaft with a groove; in fig. 4 is a view along arrow A in FIG. 3
    The shaft with the groove is made in the form of a cylindrical shaft 1 with pins 2 and 3 at the ends (Fig. 1). On the shaft 1, several lanes 4 are screwed along a helical line. The screw winding 5 passes over the entire surface of the shaft 1 and is fastened at the ends with end plates 6. The strip 4 forms grooves 7 passing along a helical line.
    The strips 4 have a rectangular cross-section, are wound around the shaft 1 on the edge and the inner short sides of the cross section are adjacent to the outer surface of the shaft 1, and the opposite side of these strips forms the outer working surface 8 of the shaft.
    The individual turns of the strips 4 with their side surfaces 9 and 10, which are opposite to each other, do not directly adjoin each other, and are fixed at a certain axial distance with the help of the rod 11. The rods 11 are spaced from the working surface 8 of the shaft for a certain radial distance h corresponding to the depth of the annular grooves 7.
    Thus, the outer zones of the side surfaces 9 and 10 of yolos 4 form the sides of the annular groove 7, and the rod I forms the bottom 12 of the groove.
    In the first embodiment (Fig. 2a), the rod And has a circular section and is located in the grooves 13 of the strips 4 provided on the side surfaces 9 and 10 of the strips 4 opposite to each other in the axial direction, pa of the same height: those, t. e. opposite each other. The bar And passes in the grooves in the same direction as the strip 4 between the turns of the latter.
    Below the bar I, i.e., between the latter and the outer surface of the shaft 1, on the strip 4 there are also passing in the longitudinal direction, located at the same height on both side surfaces 9 and 10 of the groove 14, in which between adjacent turns of the strip 4 is located the other bar 15. By the bar 15, the lane 4 receives the dpaw in two places having some radial distance, and therefore the lane cannot tilt around an axis that runs perpendicular to the plane of the drawing.
    In the second embodiment (Fig. 26), the rod 15 is wound directly on the outer surface of the shaft 1 between the turns of the strip 4. In this embodiment, the groove 14 is not required.
    In the third embodiment (Fig. 2c), bars 11 and 15 are provided, which have a round, and approximately square cross-section. Grooves 13 and 14 on both side
    .i fe "sr-4 a
    the surfaces of the strip 4 in this case have a corresponding section shape. The advantage of this type of cross-section bars is that the location of the bars p of such grooves in the radial direction is more stable than in the grooves of circular cross-section.
    In the fourth embodiment (Fig. 2d) there is provided only one bar 11, made
    also in the form of a strip of rectangular cross section and wound on an edge along the outer surface of shaft 1 between the turns of strip 4. The shorter side of the section of the bar I determines the axial distance between
    the coils of the strip, while the longer side of the same section, i.e., the width of the twist and the AND, determine the depth of the groove.
    Shaft 1 is rotated on a machine or similar device in the direction of arrow 16 (FIG. 3).
    The strip is first fed in the form of a raw rectangular profile strip 17 and then GEO goes two technological positions 18, which affect
    strip 17 from various sides. Each technological position contains a support for the strip 17 in the form of a guide ram 19 through which the strip 17 passes. This strip to the guide bar 19
    two guide rollers 20 are pressed, which are mounted at the ends of the guide bar. Between the guide rollers 20, a milling cutter 21 consisting of two
    one above the other milling cutter 22.
    The disk mills 22 in the passing lane 17 cut two overlapping grooves 13 and 14 arranged above one another.
    Instead of disk mills, you can use
    n other profiling tools, such as cutter. The profiling process can also be carried out separately from the winding process, and the profiled material can be used for orientation.
    After cutting the grooves 13 and 14 out of the strip 17, the strip 4 is produced in accordance with the first embodiment design (Fig. 2a). After exiting the second technical position 18 (Fig. 3 and 4), lane 4 passes
    directional roller 23, slowing down to distance; equal distances) between ayaykami 13 and 14, and ai their high & th ringCYTHS grooves 24, with which the rod And and the rod 15th iNaYaEybvremenno
    (Fig. 4). At the same time, bars 41 and 15, paicno-laid between the threads of the strip 4, provide the necessary distance between the individual turns. To obtain a tight winding in the axial directions and to create a good contact adjacent to each other in the axial direction of the surfaces of the strip 4 or the rods 11 and 15, clamping rollers 24-27 are provided, of which the pressure roller 24 is located near the point of incident of the strip 4 on the shaft 1, then while the pinch rollers 25-27 are distributed around the perimeter of the first.
    The strip 4 is deformed during winding on the rib, but this does not cause difficulties, since it is very tight and it is guided by pressure rollers 25-27. The dimensions of the strip 4 depend on the dimensions of the annular groove 7 and on the spacers between the grooves. The strip may have, for example, a height of 10-12 mm and a thickness of 2-4 mm. Preferably, corrosion-resistant steel is used as the material for the strip 4 and the bars 11 and 15.
    FIG. 3 also shows the head of the welding machine 28, which in the exemplary embodiment is represented as a head for spot welding and performs spot welding with a predetermined clamp. The welded points 29 connect the individual turns of the strip 4 to the rods 11 and 15.
    The rods can also be connected to strips by continuous welding, soldering or gluing.
