    Gegenstand der Anmeldung ist ein Wälzfräser mit Schneidplatten für die Herstellung von Verzahnungen. Die Anmeldung verfolgt den Zweck, einen Wälzfräser zu schaffen, bei dem einzelne Bausteine mit nur wenigen Zähnen im Falle des Verschleißens oder einer Beschädigung der Sitze der Wendeplatten ausgetauscht werden können gegen gleichförmige Zahnträger. Dabei soll es nicht notwendig sein, eine vollständige Zahnscheibe ersetzen zu müssen und überhaupt den Wälzfräser aus der Maschine ausspannen zu müssen. Außerdem sollen die Einzelteile gleichförmig sein. Nach der Erfindung ist vorgesehen, daß auf dem Fräserkörper (1) mehrere schraubenförmige Zahnsegmente (2, 2') in einer gewindeförmigen Führung (7, 8, 9) des Fräserkörpers (1) befestigt sind, wobei die Zahnsegmente (2, 2') unter einem drallförmigen Versatz der Schneidenden angeordnet sind.

    2. A milling cutter according to claim 1, characterized in that the helical segments are installed with an offset along the helix relative to the generatrix parallel to the axis of the milling cutter.
    3. A milling cutter according to claim 1, characterized in that the helical segments have the same shape
    4. The milling cutter according to claim 1, is different from that. helical segments have an angle not a multiple of 360.
    090258
    5. A milling cutter according to claim 1, characterized in that two rotary cutting inserts are fixed on one tooth of the helical segment,
    and on its other tooth is fixed one rotatable cutting plate.
    6. A milling cutter according to claim 1, characterized in that the rotatable cutting inserts at the bases are fixed alternately from opposite sides on separate teeth x.
    The invention relates to mechanical engineering, in particular to worm-milling cutters for cutting cylindrical gear wheels. .
    The worm is known for a milling cutter, on the case of which a row with fixed teeth is placed along the guides in rows. their heads alternately from opposite sides and at the bases of rotary cutting plates l.
    Known chervna cutter has the following disadvantage. Since the service life of the seats for the rotary cutting inserts is different, in order to replace individual nests, it is necessary to remove the milling cutter from the machine, disassemble it and replace the whole discs that make up the milling cutter.
    The purpose of the invention is to eliminate this drawback and increase productivity.
    The goal is achieved by the fact that in a screw mill, on the cases of which there are rows of guides with teeth mounted on their heads alternately from opposite lateral sides and at the bases of rotary cutting plates, the teeth are placed on the milling cutters and placed on guides helical segments.
    Spiral segments are installed with an offset along a helical line relative to the generator, parallel to the axis of the cutter.
    Spiral segments have the same shape.
    Spiral segments have an angle not a multiple of 360.
    On one tooth of a screw-shaped segment two rotary are fixed
    cutting inserts, and one rotatable cutting insert is fixed on his other tooth.
    Rotary cutting plates at the bases are fixed alternately
    0 from opposite sides on separate teeth x.
    FIG. 1 shows the arrangement of the helical segments on the cutter body; in fig. 2 is a view A of FIG. one;
    5 in FIG. 3 shows a section BB in FIG. 2; in fig. 4 is a view of B in FIG. 2
    On the housing 1 of the worm milling cutter, spiral segments 2 are placed along the guides 3
    0 body, which are made in the form of threaded protrusions or threaded grooves. On the helical segments there are rows of 4 teeth 5. On their heads 6, alternately with opposite lateral side walls and at the bases 7, rotary cutting plates 8 are fixed.
    Spiral segments of the set-, Lena offset by a helical line
    0 Spb relative to the generator cd, parallel to the axis of the mill 0-0. Spiral segments have the same shape. Spiral segments have angles not a multiple of 360 °. On one tooth of a spiral segment 2
    Two rotary cutting inserts 8 are fastened, and on the other tooth of the tooth one rotatable cutting is attached.
    plate 8. Rotary cutting points at the bases are fixed alternately from opposite sides on separate teeth x.
    Fastening the helical segments on the cutter body is carried out with slop; radially arranged bolts 9.
    By selecting the angle C of the helical segments, it is achieved that the swivel plates of the adjacent turns of the wormhole (located on
    heads, cut into the workpiece one after the other along a helix 0) 6. Thanks to this, the smoothness of the milling process is increased.
    The invention provides the possibility of replacing individual helical segments without disassembling the worm milling cutter and removing it from the machine tool, which ensures a higher productivity of tooth cutting.
