    A gear cutting machine and method for fabricating workpieces, especially steering segments, for transmissions having a variable transmission ratio, wherein there takes place between the workpiece and a gear cutter or hob a part-rolling or generating movement composed of a generating rotation about the workpiece axis and a generating displacement transverse to the workpiece axis as well as a to-and-fro cutting movement along the workpiece axis. An additional movement, controlled by a template and directed transverse to the workpiece axis, alters the course of the generating curve of the workpiece. This additional movement controlled by the template constitutes a change of the work position of the gear cutter and which change is directed transverse to the generating displacement.

    in vertical; in fig. 2 shows the kinematic scheme ctaHKa, in which the first copier is arranged in a vertical plane and the second in a horizontal one.
    Process the gear product in the form of the black sector 1, medium
    The tooth 2 of which, compared with the other teeth 3, has an initial contour shift from the product axis 4, therefore the middle tooth 2 is thicker than the other teeth 3. Such decals are designed for steering systems. The treatment is carried out under rolling conditions.
    In this case, the product is informed about rotation around its axis (along arrow a) and straight-line movement along the tooth-shaving comb 5 along arrow
    . b, and the comb 5 - the return-to-motion movement along the arrow c and the additional movement 5 along the arrow g,
    The latter is reported by spreading the comb around an axis parallel to the linear motion of the product fno
    b).
    arrow
    The product (the wormhole sector) 1 is mounted on the table B, which can rotate in both versions of the machine around its vertical axis 4. The table b is located on the carriage 7. The latter is installed with the possibility of movement along the horizontal guides 8 of the slide 9. Skid 9 placed on the guides of the bed 10 with the possibility of moving along the arrow d directed at a right angle to the straight-line movement along the arrow b.
    The incisal carriage 12 is moved vertically by the bed guides 11 of the bed. The reciprocating movement of the tool carriage 12 along the guides 11 (the arrow in) means the planing movement. On the incisal carriage 12, the holder 14 for the comb 5 is rotatably mounted around the horizontal axis 13. The axis of rotation 13 runs parallel to the direction of movement along the arrow. The holder is fixed to the tooth comb on the comb 5. The movement that the comb 5 performs when the holder 14 rotates about axis 13, and means an additional movement of the comb along the arrow G. The angle of rotation of the holder 14 is limited so that the additional movement takes place essentially at a right angle to the axis 4 of the product 1,
    On the table b, the copier 15 of the copier with the roller 16 and the probe 17 mounted in the housing 18 on the carriage 7 is mounted with the possibility of movement parallel to the linear motion along the arrow b. On the skoup 17 is made rack
    cutting 19, with which the pinion gear 20 is rolling, is fixed at one end of the shaft 21. At the other end of the shaft is placed the second pinion gear 22, in contact with the pinion gear cut 24 cut by the pusher 23.
    The pusher in the first embodiment of the machine (Fig. 1) can move vertically, i.e. parallel to the axis 4 of the product and the reciprocating movement of the comb, and in the second embodiment (figure 2) - horizontally, i.e. under gtr kim angle to the axis 4 of the product and the reciprocating movement of the comb. The pusher 23 is compressed by the spring 25 so that the roller 16 is constantly pressed against the copier 15.
    Common to both versions of the machine is that at the end of the pusher
    23 opposite rack pair
    22-24, the cam 26 of one cam mechanism is strengthened with the possibility of replacing, by which the roller 27 mounted on the slide 29 is driven in,
    placed in the second housing 29, mounted on the base 10, with the possibility of movement parallel to the pusher 23 (either vertically or horizontally). In case 29 in both
    In the embodiments there is a second copier, which is a pusher 30 disposed parallel to the direction of the forward movement along the arrow b of the roller 31 and the copier 32.
    At the end of the pusher 30, the second cam mechanism is reinforced, which is a cam 33, roller
    0 34 and the probe 35 in the form of a two-armed lever mounted on the axis 36, mounted on the incisal carriage 12. In the first embodiment, the axis 36 is raspolokh (en under the linear angle to the axis 4 of the product,
    5 in the second embodiment — parallel to the axis 4 of product 1. The end of the probe 35 is pivotally hinged to the axis 36, which is installed in the incisal carriage 12 for movement parallel to the direction of linear movement along arrow b and provided with a guiding element 37 with an oblique guide surface, the roller 38 is driven around. The roller 38 is fixed on the holder 14 and can be rotated on the vertical axial 39 and forms an angular gear together with the guide member 37. The guide element 37 is provided with a spring 40, with which the roller 34
    O is pressed against the cam 33. In the first embodiment, the machine is equipped with an ear-shaped stop 41, which is mounted on the incisal carriage 12 with the ability to control the rotation of the probe for 35 s
    5 using an eccentric 42.
    ZubostrogalkyN (in both presented embodiments, the implementation works as follows.
    The rotation of the rolling motion along the arrow, and the straight-line movement of the product along the tooth-forming comb are in agreement with a known mechanism / rolling (not shown in the drawing) and is performed by one common drive. Simultaneously with rolling of rolling and direct movement of the product. reciprocating movements are reported to the comb, and the holder 14 with the tooth-shaped comb 5 during each downward movement takes up the working position, and during each upward movement the neutral position. The neutral position is provided by means of a known, for example electromagnetic or hydraulic actuator by an additional movement is reported to the comb and the holder 14 is deflected away from the product axis 4 on the axis of rotation 13.
