    39 of the head to the base of the tooth, or before the end of grinding of the involute profile from the head to the base of the tooth and immediately after the subsequent grinding of the opposite profile of the same depression from the base to the head of the tooth. The device is equipped with an additional drive of a linear movement of the grinding wheel mounted on the bracket and kinematically connected with the feed mechanism and the straightening device, and the mechanical gear is a gear wheel with two gear racks engaged with it, one of which is fixed to the bracket , a friend is on the straightener. An additional drive is kinematically coupled to one of the slats. FIG. Figure 1 shows a diagram of a method for grinding a cylindrical wheel with an involute profile; Fig. 2, a device for grinding a cylindrical wheel, a general view; FIG. 3 shows one embodiment of the drive for additional linear movement; in fig. k is another design variant of the drive for additional linear movement. The method is carried out as follows. Grinding of a cylindrical gear wheel 1 with an involute profile is carried out under rolling conditions with a single disc 2 wheel. At the same time, along with the evolvent profile a6, the transitional bottom of the cavity cd is polished as a transitional curve. along arrow A. This movement can be carried out at any phase of the rolling movement: between two division movements at the end of grinding an involute profile from the head to the base of the tooth, before the end of the section Vani involute profile from the head to the tooth base circle and withdrawn immediately prior to the subsequent grinding of the opposite profile of the depressions of the same name from the base to the tooth head. A device for grinding cylindrical gears is made as follows. :. The device has a base 3 on which the slide 4 is arranged with the possibility of longitudinal movement, i.e. parallel to the axis 00 of the ground, gear 1, reciprocating movement of the slide k is produced by a 5-type drive (not shown). On the sleeves k there is a carriage 5 with the possibility of reciprocating movement perpendicular to axis 00. The slider 4 is connected with a crank mechanism 6, which causes the carriage 5 to reciprocally move with the help of a slider 7 with adjustable eccentricity, On the carriage 5 is located with the possibility of rotation about the axis 00 of the clamping mandrel 8, carrying the gear wheel 1 and kinematically connected with the rolling mechanism, which is located on the slide k with the ability to move perpendicular to the axis 00 rack 9, connected by means of rolling strips 10 to the frame 11,. On the rack 9 a slider 12 is placed, moving along the groove of the scenes 13, which can be rotated at an angle (in the case of grinding helical gears) on a plate 1 mounted on the base 3 with the possibility the translational movement is parallel to the axis 00. On the base 3 there is an instrumental stand 15 which can be rotated about the vertical axis 0 | 0 |. On the tool stand 15, the caliper 16 is mounted with the possibility of rearrangement in height, which carries two symmetrical relative to each other bracket 17 installed with the possibility of oncoming movement along the caliper 16. On each bracket 17 the grinding head 18 is positioned with the possibility of rearrangement in height, On each grinding headstock 18 there is a dish-shaped grinding wheel 2; On each of the grinding heads 18, a device 19 for aligning the grinding wheel is mounted with the possibility of vertical movement ha 2, having a roller for dressing 20 and measuring pin 21, A gear 22 is located on each grinding head, engaging on one side with a rack 23 perpendicular to the corresponding bracket 17 and a rack 23 on the other side with a fixed fixture 19 rack 2k. For height adjustment, each grinding headstock 18 has a vertical spindle screw 25.
    Two variants of the design of the drive for additional linear movement of the grinding wheel are presented.
    According to one embodiment, the lead screw 25 is located in a horizontal wedge plate 26 placed with the possibility of shifting in height in the bracket 17. The wedge plate 26 is located on the wedge support 27 mounted on the bracket 17 with the possibility of shifting in the horizontal direction, so that when the wedge support 27 is wedge plate 2b shifts parallel to itself up or down.
    At the upper end of the lead screw 25, a gear wheel 28 is engaged, which engages with gear 29 located on the wedge plate 26 and is rigidly connected to the ratchet wheel 30, which interacts with the latch 31 connected to the hydraulic rod; cylinder (pneumatic) cylinder 32, the piston of which is spring-loaded spring 33 in the direction opposite to the operation of the ratchet wheel 30. The cavity of the cylinder 32 on the side opposite the ratchet wheel 30 is connected by a pipe 3 with a pressure source (not shown). The rotation of the ratchet wheel 30 by one tooth and thereby the rotation of the spindle 25 is carried out by the cylinder 35.
    A double-acting cylinder 35 is provided for moving the wedge plate 26, the two cavities of which are connected by pipes 36 or 37 and by means of solenoid valves 38 or 39 to the pump Q. The solenoid valves 38 and 39 are electrically connected to the control unit 1 and the distribution board. .
    On the wedge plate 26 there is a displacement transducer that interacts with the bracket 17 of the grinding headstock 18 and is connected in the same way to the control unit. At each re-installation of the wedge plate 2b in height relative to the wheelhead bracket 17, the displacement sensor delivers
    corresponding signal to the control unit.
    On the wedge plate 26, a vertical bar k is fixed, vertically guided on the bracket 17 of the grinding headstock 18 with the possibility of permutation in height. A rack rail 23 is fastened to the rod 3. According to the second embodiment of the drive for additional movement, the drive screw 25 is fixed directly in the bracket 17 of the grinding headstock 18 in such a way that it can only be moved along with it. At the upper end of the lead screw 25, a screw-shaped worm is fixed to which is fastened to the shaft of the stepping motor 45 and can be connected via clutch 46 with another screw +7. The latter engages with a worm gear 8 mounted on a lead screw 9, which is stationary axially on the bracket 17 of the grinding headstock 18. The lead screw k can be screwed into the internal thread made on the rack 23 so that any rotation of the lead screw 49 caused the displacement of this rack 23 in height
    The operation of the device is as follows (in principle, both devices work in the same way).
    Grinding is performed under rolling conditions, with a single division.
    Grind spur gear with involute profile is fixed in mandrel 8. When carriage reciprocates on skid k, while instrumental stand 9 is stationary relative to skid 4, gear gear 1 performs rolling, sluggishly from transverse motion of carriage 5 and overlapping rotation of the wheel 1 around its own axis 00. The reciprocating movement of the slide 4 along the axis 00 then causes the rack 9 to perform reciprocating transverse movements on the carriage 4 and therefore said flow forming wheel 1 by means of belts 10 additional rotary indexing motion on nakladyvayuschies dividing pivot motion caused vozvratnopostupatelnymi transverse movements of the carriage 5.
    In the case of processing the helical wheel, the link 13 is set at an angle equal to the angle of inclination of the teeth with the axis 00.
    The movement of the wedge support 27 to the right, conditioned by the cylinder 35, in turn, gives the movement of the wedge plate 2b downwards and the lead screw 25 and the rod 43 are involved in this movement. As a result, the grinding wheel 18 and the rack rail 23 simultaneously move along and a wedge plate 26. The gear 22 displaces the rack 2 and thus the entire straightening device 19 by the same amount so that the grinding head 18 is lowered. This lowering is a feed movement that is not associated with the dressing of the grinding wheel 2 and therefore shifting the active grinding point down to the bottom of the tooth.
    If the grinding wheel 2 is to be adjusted, then the cylinder 32 rotates the lead screw 25 and thereby lowering the wheelhead 18, in which the wedge plate 2b does not take part, and also the rack rail 23. As a result, the lowering of the wheel head 18 is due to gear rotation 9, as a result of which the latter moves the dressing device 19 relative to the grinding headstock 18 downwards. With each vertical movement of the grinding headstock 18, defined only by the power cylinder 32 and not connected with the displacement of the wedge stand 27, the dressing device 19 moves by a double amount.
    The proposed device improves the accuracy and quality of cylindrical gears with involute profile.
