    A method of grinding gears is provided, wherein a workpiece support and a tool base are movable relative to one another for partial movements of the workpiece, for setting the gear teeth data, for accomplishing movements for configuring a tooth profile, and for the to-and-fro lengthwise stroke along the tooth flanks to be ground. A grinding wheel support is mounted at the tool base for pivotable movement about a pivot axis and a grinding wheel is mounted to be rotatably drivable at the grinding wheel support. The axis of rotation of the grinding wheel extends transversely with respect to the aforementioned pivot axis. The grinding wheel support is connected with the tool base by a pivot drive which, during grinding of a tooth flank, enables random changes of the grinding-pressure angle or angle of attack between the grinding wheel and the tooth flank.

    (54) METHOD OF POLISHING GEAR WHEELS AND MACHINES FOR ITS IMPLEMENTATION The invention relates to metal working and will find application in machining gears. There is a known method of grinding gear wheels, during which a change is made in the angle of incision, the latter increasing from the tooth foot to its middle area, and the grinding wheel is set so that it touches the point on the side surface of the tooth. Known gear grinding machine working by a known method. The machine head and the tool stand are installed on the machine bed, on which the plate is mounted with the possibility of moving perpendicular to the product axis, carrying the caliper with the grinding wheel l fixed on the bracket. A disadvantage of the known method and device is low grinding performance. The purpose of the invention is to increase the grinding performance. In order to achieve the goal, the cutting angle is reduced from the middle region of the tooth to its heads and, at this grinding wheel, an additional turning is reported and the distance from the axis of the additional turning to the touch point of the tooth side surface is adjusted by the grinding wheel. The value of the distance correction does not exceed 10 mm, and the angle of incision is in the range from 0.5 to 25. The machine is equipped with a mechanism for changing the cutting angle of the grinding wheel, and circular guides are made on the plate, on which a caliper is mounted, which is connected by means of a mechanism for changing the cutting angle to the plate, the bracket being placed on the slide with the possibility of moving in two directions. with each other and with the axis of the circular directions right angle. Figure 1 is a diagram of a grinding method; Fig. 2 is a general view of a gear teeth grinding machine for grinding straight cylindrical wheels; in Fig. 3, a grinding wheel feeding unit; Fig. 4 is a general view of a gear grinding machine for grinding helical gears. Grinding gears with a grinding wheel 2 in
    conditions of rolling, and in the process of grinding there is a change in the angle of incision Jfg, i.e. the angle between the tangent to the side surface of the tooth of the wheel 1 from its middle region and the torus with the price of a surface of a circle 2, Tangency point P. The change in the cutting of the tooth's tooth (Pf tangent f) to its middle area (P) occurs because the initial setting of the grinding wheel does not change, and as a result of rolling, the cutting angle increases. From the touch point P4, reducing the plunging angle to its head (p-tac -Ig), an additional turning is reported to the grinding wheel, and .DELYING to achieve the desired profile, the distance f from the turning circle of the circle (point B) to point PI is adjusted. The axis of the circle turning (point B) passes near the point P / in which two tangents to the main circle (radius) intersect one another with the profile to be ground, namely the tangent -fcg through the point PQ of the tooth and the tangent {. through the point of the leg of the P
    The magnitude of the distance correction does not exceed 10 mm, and the magnitude of the variation of the incision angle is in the range from 0.5 ° to 25 °.

    Claims (4)
    [1]
    In this machine, the machined wheel 1 is fixed in connection with which a conventional type of rolling mechanism is not required to carry out the rolling motion of the gear wheel 1 and the wheel 2, since all the necessary movements with the stationary gear wheel 1 can produce rotation of the circle 2, movement salazon 22 from actuator 24 and caliper 16 from actuator 21. Option Fig. 3) is possible to rotate circle 2 directly from actuator 27 through belt 42 associated with actuator 43. Actuator 43 can be fixed to plate 13 A variant is presented (FIG. 4)making a gearshift machine suitable for grinding both the spherical cylindrical wheel 1 and KOco3V 6oro of the cylindrical wheel 44. This requires a helical relative movement between the wheel 44 and the wheel 2, which must be synchronized with the movement of the stand 11 along the guide 8 of the slide 7 . For this purpose, on the headstock of the product 4, the rolling mechanism is fixed in the form of a sector 45 of the rolling lines 46, passing through the rollers 47 and fixed on a stand 48 located on the base 49, mounted on the frame 3 with In order to move along the guides 6 at a right angle to the axis of rotation of the spindle 5 of the headstock of the product 4. The stand 11 is located in the horizontal plane of the directional slide 50, where the rocker 51 is mounted. The grinding wheel should be inclined according to the angle of the helical gear 44 . For this purpose, grinding spindles Del 26c are mounted on one side in sleeve 52, and on the other hand in ring 53. Sleeve 52 is mounted on the fixed arm 54 of the bracket 55. Ring 53 is installed with the possibility of rotation around the axis paraplelny in his ear 56, which is hinged mounted on the shoulder 57 crown of the matte 55 by means of the clamping element 58. The additional support 59 is connected with the sleeve 52 and through the rack and pinion gear 60 moves from the actuator 61 from or to the grinding wheel 2. Thereby the axial wear of the grinding wheel is compensated for It supports axial movement, and synchronously with such movement, the support 59 always moves by the same amount. The support 59 assumes part of the functions provided in the machine for grinding the sprockets of the slide 22. Thus, the support 59 is provided on the support 59. , along which the wheel straightening mechanism moves from the actuator 63, similar to the wheel straightening mechanism on a machine for grinding sprub wheels. The machine works in the following way (an example of a variant of processing of spur spur wheels). The gear wheel 1 being machined is stationary when the side surfaces are ground. The bracket 25 is set in such a way that the grinding point p ,, in which Circle 2 touches the side surface of the tooth 1, is at a distance of dd from the rotary axis 15 (point B). During grinding, circle 2 performs forward and reverse rotations around axis 15 (point-B). These rotations are superimposed by movements of the bracket 25 along the direction of travel x 23 in such a way that the grinding point P would move in the forward and reverse directions between PQ on the head of the tooth and the point P on the leg of the tooth, if the rack 11 was fixed. During grinding, the hub 11 continuously moves along the guide-dix 8, so that the grinding point P moves in a zigzag manner along the side surface of the tooth. The movements of the bracket 25 along the guides 23 are necessary, since the tooth profile to be ground is more or less strongly deviated from the arc of the circle and therefore cannot be ground only by turning the circle 2 around the axis 15 (point B). The amount of movement required by the bracket 25 along guideways 23, which as a result are axial movements of circle 2, depends on where the pivot axis is located relative to the side surface of the tooth to be ground. Axis 15 (point B passes predominantly near point Pj. Turns of a circle 2 around axis 15 (point B) during grinding are constantly combined with axial movements of the grinding wheel, i.e., from the drive 24, movements of the bracket 25 along the guides 23 and from the actuator 21 by moving the rails 22. along the guides 20, which, on the one hand, requires the desired flank surface profile and, on the other hand, the grinding plunge angle constantly changes, resulting in an increase in productivity. cog o-, the wood, during which the incision angle is changed, the latter is enlarged from the tooth leg to its middle area, and the grinding wheel is set so that it touches the point at the side of the tooth surface, characterized in that a reduction in the penetration angle from the middle region of the tooth to its head, with the grinding wheel being reported
