Description

Известны компенсационные электротахометры, состо щие из электрической машины и блока сравнени  измер емой скорости с эталоном.Compensatory electrochotometers are known, which consist of an electric machine and a unit for comparing the measured speed with a standard.

В отличие от известных, с целью повышени  точности измерени  скорости вращени  валов, в качестве электрической машины использован сельсин-двигатель, а в качестве блока сравнени  - дифференциал, одна из входных осей которого присоедин етс  к валу контролируемого объекта, друга  соединена с валом полого ротора сельсин-двигател , а выходна  ось св зана с осью поворотного внутреннего статора сельсиндвигател . Обмотки статоров сельсин-двигател  выполнены распределенными и к ним подключены сельсинчдатчики дл  дистанционного задани  скорости, при которой должны срабатывать контакты, управл емые тахометром.In contrast to the known, in order to improve the accuracy of measuring the speed of rotation of the shafts, a selsyn-motor is used as an electric machine, and a differential, one of the input axes of which is connected to the shaft of the object being monitored, is connected to the shaft, and the other one is connected to the shaft of a hollow rotor. is the motor, and the output axis is connected with the axis of the rotating inner stator of the selsindvigatel. The windings of the stalsin-motor stators are made distributed and are connected to them by the resolver sensors to remotely set the speed at which the contacts controlled by the tachometer should operate.

На чертеже изображен предложенный компенсационный электротахометр .The drawing shows the proposed compensation electrotochometer.

Компенсационный электротахометр состоит из совмещенного сельсин-двигател  / и дифференциала 2.The compensation electrochotometer consists of a combined selsyn-engine / and differential 2.

К входным ос м дифференциала подведены вал 5. скорость которого измер етс , и вал 4, св занный с полым ротором сельсин-двигател  1. Выходна  ось 5 дифференциала св зана с осью поворотного внутреннего статора сельсин-двигател . Обмотки статора сельсин-двигател  могут быть выполнены распределенными, что позвол ет с помощью сельсин-датчика 6 дистанционно задавать скорость, при которой,требуетс  в функции угла поворота внутреннего статора замыкать сигнальные контакты.Shaft 5 is brought to the input axes of the differential. Its speed is measured, and shaft 4 connected to the hollow rotor of the selsyn engine 1. The output axis 5 of the differential is connected with the axis of the rotary internal stator of the selsyn engine. The stator windings of the autosyn engine can be made distributed, which makes it possible by means of the resolver 6 to remotely set the speed at which the signal contacts are required as a function of the angle of rotation of the internal stator.

Принцип действи  предложенного компенсационного электротахометра , в соответствии с чертежом, заключаетс  в том. что скорость п вала 4, непрерывно сравниваетс  в. дифференциале 2 с измер емой скоростью rti вала 3. При несовпадении измер емой скорости выходна  ось 5 дифференциала, со скоростью, пропорциональной Дп будет пово рачйвать внутренний статор сельсин-двигател  /, вследствие чего будет 6 соответствующую сторону измен тьс  число оборотов полого ротора.The principle of operation of the proposed compensation electrochometer, in accordance with the drawing, is. that the speed of the n shaft 4 is continuously compared in. the differential 2 with the measured speed rti of the shaft 3. If the measured speed does not match, the output axis 5 of the differential, with a speed proportional to Dp, rotates the internal stator of the selsyn-motor, resulting in the corresponding rotational speed of the hollow rotor.
