Description
Известны устройства дл проверки линейности намотки потенциометров , содержащие стенд дл установки провер емого и образцового потенциометров. Движки потенциометров механически св заны между собой дл одновременного их перемещени и электрически присоединены к входу электронного усилител , на выходе которого включен реверсивный двигатель.Devices for checking the linearity of the winding of potentiometers are known, which contain a stand for mounting tested and exemplary potentiometers. The potentiometer motors are mechanically connected to each other for simultaneous movement and electrically connected to the input of an electronic amplifier, the output of which includes a reversible motor.
Последний предназначен дл компенсации разностного напр жени потенциометров и одновременного перемещени пера регистрирующего прибора.The latter is designed to compensate for the differential voltage of the potentiometers and simultaneously move the pen of the recording instrument.
Отличительной особенностью -предлагаемого устройства вл етс то, что, кроме непрерывной записи линейности, одновременно записываетс величина отклонени угла намотки потенциометра, котора в .л етс важной частью характеристики его. Эта запись осуществл етс без каких-либо дополнительных элементов схемы, примен емых в известных устройствах и усложн ющих процесс производства записи. Указанное преимущество достигаетс тем, что вал реверсивного двигател механически св зан с корпусом провер е.мого потенциометра и осуществл ет поворот последнего до уравнивани напр жений обоих потенциометров .A distinctive feature of the proposed device is that, in addition to the continuous recording of linearity, the value of the winding angle of the potentiometer, which is an important part of its characteristic, is also recorded at the same time. This recording is carried out without any additional circuit elements used in known devices and complicating the recording process. This advantage is achieved by the fact that the shaft of the reversing motor is mechanically connected to the body of the tested potentiometer and rotates the latter before equalizing the voltages of both potentiometers.
На чертеже изображена блок-схема устройства.The drawing shows a block diagram of the device.
Измерительна часть схемы - мост состоит из контрольного / и испытуемого 2 потенциометров. От блока 3 питани на одну из диагоналей моста подаетс напр жение, втора диагональ соединена с электронным усилителем 4 посто нного тока.The measuring part of the circuit - the bridge consists of a control / and test 2 potentiometers. From the power supply unit 3, a voltage is applied to one of the bridge diagonals, the second diagonal is connected to the electronic amplifier 4 of the direct current.
Ползунки потенциометров / и 2 кинематически св заны чере.- редуктор 5 с валом двигател 6. Отклонение от линейности испытуемого потенциометра вызывает разбаланс моста. Напр жение сигнала рассогласовани моста подаетс на вход усилител 4, на выходе которого включена управл юща обмотка двухфазного асинхронного двигател 7. Этот реверсивный двигатель через редуктор 8 вызывает поворотSliders of potentiometers / and 2 are kinematically connected through a gearbox. Gearbox 5 with the motor shaft 6. Deviation from the linearity of the tested potentiometer causes imbalance of the bridge. The voltage error of the bridge is applied to the input of the amplifier 4, the output of which is connected to the control winding of a two-phase asynchronous motor 7. This reversible motor through a gearbox 8 causes a turn
