Description

one

The invention relates to the field of instrumentation technology, namely to the control gears.

Devices are known for monitoring the accumulated error of the circumferential pitch of gear wheels, which contains a sensor for the angle of rotation of the wheel being monitored and a contact device that fixes its tooth position.

The closest to the proposed device is a device containing its mandrel for stirring the monitored wheel, drive vra, mandrel with a rotation angle sensor, a photoelectric sensor for stirring, and a register: operating unit.

The measurable gear wheel is mounted on a mandrel in the center with which the wheel angle sensor is rigidly connected. The measuring tip of the stirring sensor is brought into contact with the tooth of the wheel to be measured. The wheel is rotated until the tip is set to a certain position, fixed by the reading device of the mixing sensor. The magnitude of the accumulated error in the circumferential pitch is counted on a scale of the angle of rotation sensor.

The disadvantage of the described device is the laboriousness of the measurement due to the use of contact means for this purpose.

The aim of the invention is to improve the accuracy and performance of the control.

To achieve this goal, the device is equipped with an electronic unit containing a signal amplifier of an inductive sensor, a differentiator link, to the input of which a photoelectric sensor is connected, an electronic switch, whose inputs are connected to the output of the amplifier and differentiate: its link, and remember its link that is turned on and electrically connected with registering them.

In the proposed device, the signal of the inductive sensor is transmitted to the registering node in the system to achieve the extreme value of the photoelectric sensor signal during continuous insertion of the monitored gear.

The invention is explained in the devil system.

Controlled gear / mounted on the mandrel 2, placed in the center. An angle sensor 3 is located coaxially with the mandrel associated with the rotational drive 4. The photoelectric sensor 5 is directed toward the working surface of the tooth of the wheel to be monitored. The photoelectric sensor and the angle sensor are electrically connected to the electronic unit 6 and the register node 7.

The device works as follows.

The luminous flux separated from the working surface of the tooth of the controlled wheel /, when the latter is rotated by the drive 4

creates at the output of the photoelectric sensor 5 a triangular signal. From sensor 3, a sinusoidal signal is removed. The electronic unit 6 for processing information from the sensors 5, and 5 comprises an inductive sensor signal amplifier, a differentiating element, an electronic key and a storage element.

The signal from the photoelectric sensor is differentiated and at the moment the derivative is zero, i.e. at the time of the extreme value of the output signal from the photoelectric sensor 5, the electronic key is opened, and the signal of the angle converter, amplified by an amplifier, is fed to a memory device that stores the value of the angle signal converter

In the event that the accumulated error of the circumferential bridge is zero, the signal from sensor 3 remains constant at each measurement moment, if the circumferential pitch error is different from zero, then the value changes.

sensor signal 3 at the time of measurement. The registering node 7 fixes deviations of the magnitude of the peripheral border from the nominal one.
