This invention relates to a measurement technique in mechanical engineering, namely to means for controlling gear wheels.

The purpose of the invention is to improve the accuracy of control.

The drawing shows a functional diagram of the device for the integrated control of gear wheels,

. The device contains a drive 3 of the controlled wheel 1, a transducer 4 angular turns of the wheel 1, a transducer 5 angular turns of the auxiliary wheel 2, a marker 6 turns of the wheel 2, a multiplier 7,: dividers 8 - 10 frequencies, phase meter 11 electronic key 12, recorder 13, block 14 switching,

In addition, the device contains three amplifiers 15-17, a filter 18 and two scale registers 19 and 20, made on the basis of a divider and designed to select a measurement range.

The serially connected multiplier 7 and divider 8 are connected via amplifier-shaper 16 with transducer 3OBaTenfeM 4, the output of divider 8 through scale register 20 is connected to one of the inputs of phase meter 11, the second input of which is connected through scale register 19 and amplifier shaper 15 with the converter 5, the output of the phase meter 11 is connected via a filter 18 to one of the inputs of the key 12, the second input of which is connected to one output of the switching unit 14, the second output of which is connected to the recorder. The inputs of the switching unit are connected to the outputs of dividers 9 and 10, the Marker 6 is connected via amplifier amplifier 17 to the inputs of dividers 9 and IQ, the other inputs of which are connected through amplifier amplifier 15 to converter 5, Output Key 1 2. connected the recorder 13, the Dividers 9 and 10 frequencies, the switching unit 14 and the electronic key 12 form an information sampling unit. The dividers 9 and 10 are tuned to that portion of the wheel 2 which is engaged with the wheel 1 in the process of sampling the measurement information. The divider 8 is tuned to the number of teeth of the wheel 2. The multiplier 7 is tuned to the number of teeth of the wheel 1,

The device works as follows.

From drive 3, wheels 1 and 2 are rotatable. The signals from transducers 4 and 5 after amplification and shaping, and then multiplying and dividing in the transducer 4 branch, become nominally the same in frequency, then, passing through a scale register, arrive at the phase meter inputs, which determine the phase shift

signals, proportional to the kinematic error, and then through the filter and the key to the recorder, where the kinematic error curve is recorded.

Simultaneously dividers 9 and. 10 are started from the marker 6 turns and signals from them are sent to the switching unit, which, by a signal from divider 9, opens the key and switches on the movement of the chart tape recorder, and by a signal from the divider 10 closes the key and turns off the movement of the chart tape, control the speed of which is also carried out by block 14,
