    This invention relates to mechanical engineering, namely to means for controlling gear wheels.
    A device for controlling the parameters of gears is known, comprising a frame, radial and axial slide blocks mounted on it, each of which is equipped with a drive and a gear. position sensor, rotary table linear motion sensor, control unit and data processing. When controlling, for example, the profile of the tooth, the movement is carried out by means of two movements: a rotary table and a translational tangential slide. The electronic | control and data processing unit continuously compares the data sent by the position sensors to the theoretical angular position of the rotary table or tangential slide and causes a correction of the signal sent by the linear motion sensor 1Л.
    The disadvantage of this device is the complexity of the electronic control unit and data processing, which reduces the accuracy and stability of the control.
    The closest to the invention according to the technical Essence is a device for monitoring parameters of gear wheels, comprising a frame, a radial slider mounted on it with a kinematically associated radial position sensor mounted on a radial slider, a radial drive kinematically connected with a radial slider, a tangential slider with a kinematically associated tangential position sensor, mounted on a tangential slider, an axial slider with a kinematically associated axial position rotary table for mounting gears with kinematically connected rotary position

To measure, for example, the tooth profile in the memory of the electronic control and processing unit. The data is entered into the desired profile of an involute controlled gear, where it translates into a theoretical path along which the linear displacement sensor should be moved in order to maintain a specified distance between itself and the currently measured lateral surface of the tooth when the rotary drive and tangential drive are running. The electronic control and data processing unit generates the signals necessary for the implementation of an appropriately coordinated rotational movement of the gear around its axis and the tangential movement of the linear displacement sensor with groping tip. At the same time, the electronic control and data processing unit uses electrical signals coming from the linear displacement sensor and setting the position of its groping tip relative to the monitored tooth flank in the form of a deviation from the specified profile. At the same time, the signals of the rotational drive and tangential drive | sent; the signals are continuously compared by the electronic control and data processing unit with the theoretical angular position of the gear to be controlled or theoretically the position of the carrier sensor for linear displacements of the tangential slider. Each deviation of the actual by. A change from the theoretical value causes a correction of the signals sent by the linear sensor. As a result, signals are detected that are to some extent free from errors in moving the sliders of the C2J device. The disadvantage of this technical solution is the presence of a complex storage and computing device for accumulating data and bringing them into correspondence. Especially the control accuracy decreases if, instead of processing the data after completing the control operation, it is necessary to use them during the control process itself.

    The device works as follows.
    When controlling, for example, the profile of the monitored part 11, the radial slider 2 (FIG. 1) is moved by means of the radial actuator 4 to a position in which the linear displacement sensor 9 contacts the tooth on the radius of the main circle of the monitored part 11 (gear wheel). This position of the radial slider 2 is controlled by means of the radial position sensor 3 and the position indicator connected to the output terminal 27 (not shown / of the radial slider 2.
    Then, the test piece 11 (gear) and the linear displacement sensor 9 are rolled, and the gear wheel performs: the rotational component of the running-in motion, making turns with the turntable 10 around its axis. while the linear displacement sensor 9 performs the linear component of the rolling motion by moving the tangential slider 5.
    The rotary table can be fixedly mounted on station 1. In this case, it is necessary that by moving the tangential slide 5 a contact of the sensor 9 with the tooth of the wheel under control is placed on the radius of the main circle, for example, by placing the tangential slide 5. on the radial slide. Then this radial slider must be equipped with a radial drive | The radial position sensor and other elements: Each of the control circuits 16, 17 and 18, regardless of whether it serves the drive 13 of the rotary table, the tangential driver 14 or the axial drive, 15 (Figs. 2, 3 and 4), has the same The principal construction shown in FIG. 5. The servomotor 20 receives signals, for example, from the regulating circuit 18 axially receiving water 15 and is kinematically connected with. A tachogenerator 19 that sends signals to a speed controller 23 located, for example, inside an adjusting circuit 18 of an axial drive 15. A corresponding sensor, for example, an axial position sensor 8, is connected to a second input of a stroke regulator 22 located, for example, inside an axial regulating circuit 18 actuator 15. Thus, each control loop 16, - 17 and 18 is an integral part of two control loops, namely the position control loop, to which the setpoint value is applied as a control value. th order position of the actuator which is independent from the respective positional loop positional control. To control the tooth profile of the monitored part 11, the clock generator 30 (FIG. 2) controls the turntable 10, so that it performs the leading function. The control loop of the rotation actuator 13 13 establishes the angular position of the turntable 10 relative to the determined zero position. The calculator 32 of the position of the tangential slider transforms it by multiplying or by the established radius of the main circle in the horizontal position, which should have been. tangential crawl 5, if there were some obkatki free from errors. The signal 5 sent by the calculator 32 of the tangential crawler 5 is entered through the switch 35 as a control value into the control circuit 17 of the tangential drive and into the calculator 24 of the correction signal, the calculator 24 of the correction signal also receives a signal from the tangent signal corresponding to the actual position of the tangential slide 5 The position sensor 6 also forms a correction signal by subtracting both signals input into it. The calculator 25 errors, in addition to the correction signal, also receives a signal from the sensor 9 linear displacements, corresponding to its deviation. Since this deviation depends on the error of the running in motion and on the error of the tooth profile at the controlled point, the error calculator 25 subtracts one signal entered into it from the other for. get true error profile. This error is recorded by the recorder (not shown) connected to the terminal 26 of the error calculator 25, precisely depending on the actual position of the tangential slide 5, fixed by the pointer (not shown / position of the tangential slide connected to the terminal 28 of the electronic unit 21. At the same time remaining unchanged when checking the tooth profile, the position of the axial slider 7 is fixed by a pointer (not shown:) the position of the axial slider connected to terminal 29 of the electronic unit 21. If the part 11 is controlled is This is a toothed screw for which the step error is to be controlled, then the rotary table 10 is controlled by the clock generator 30. The signal from the rotary position sensor-12 converts the axial slider 7 (FIG. 3) to the specified position of the axial slider position 34 by multiplying by parameters characterizing the pitch. The signal of the calculator 34 of the position of the axial slider 7 is inputted through the switch 33 as a control value into the axial control loop 18 of the axial drive 15 and into the calculator 24 of the correction signal. The correction signal calculator 24 also receives, corresponding to the actual position of the axial slider 7, the signal from the axial position sensor 8 and, by subtracting the signals inputted into it, forms a correction signal directed to the error calculator 25. The error calculator 25, in addition, receives a signal from the linear displacement sensor 9 and determines, by subtracting both signals, the step error recorded by the recorder (not shown) connected to terminal 26. When monitoring the inclination of the teeth, the clock generator 36 controls the movement of the axial slider 7 and, thus, it assumes a leading function. The signals of the axial position sensor 8 are fixed by a pointer (not shown) of the position of the axial half sauna 7 connected to terminal 29 of the electronic unit 21, and the calculator 3 8 positions of the rotary table 10 to a predetermined position, which the rotary table 10 would hold if it was free from errors of movement / by multiplying the angle of inclination of the teeth of the counterpartable part 11 by the angle of rotation signal by the tangent. control variable into the control loop 16 of the rotational drive 13 and into the correction signal calculator 24. The calculator 24 correction signal iply receives the signal about the actual position of the turntable 10 from the rotary position - sensor 12 through converter 37. angular displacement to linear. From the kx of the two signals inputted into it, the calculator 24 forms a correction signal and transmits it to the calculator 25 errors. The calculator 25 uses the signal from the linear displacement sensor -9 as the second signal and calculates the tooth tilt error by subtracting both signals. This logging is recorded by the recorder (/ le shows the errors in the function of the axial position.
    The application of the invention will improve the control accuracy by 1.5 times and reduce the control time by 25%. The invention can be used in all industries where there is a production of gear wheels.
