Description
Р1звестны различные импульсные способы контрол отклонени скорости вращени вала от заданной при малых скорост х вращени с использованием мигающего источника света, фотосопротивлени и вращающегос отражател . Эти способы требуют сложной аппаратуры и могут быть использованы при вращении вала со скоростью, не меньшей 200 обIмин.Various pulsed methods are known to control the deviation of the shaft's rotational speed from that set at low speeds using a flashing light source, photoresistance, and a rotating reflector. These methods require complex equipment and can be used when the shaft rotates at a speed not less than 200 obImin.
Предлагаемый способ отличаетс от известных тем, что позвол ет существенно упростить аппаратуру при измерении малых скоростей вращени : до 200 об/мин. Это достигаетс тем, что заданный интервал времени мигани источника света осуществл етс с помощью контактов, св занных с ма тником.The proposed method differs from the known ones in that it significantly simplifies the apparatus when measuring low rotational speeds: up to 200 rpm. This is achieved by the fact that the predetermined time interval of the blinking of the light source is carried out with the help of contacts connected to the water bottle.
После каждого отклонени , которое совершаетс вращающимс флажком, ма тник возвращаетс в исходное положение под действием пружины.After each deviation, which is performed by a rotating flag, the thumbnail returns to its original position under the action of a spring.
На чертеже дана кинематическа схема устройства дл осуществлени описываемого способа.In the drawing, a kinematic diagram of an apparatus for carrying out the described method is given.
На оси вала /, скорость вращени которого контролируетс , креп тс вращающиес вместе с валом отражатель 2 и флажок 5. Фотолриставка , состо ща из фотосопротивлени 4 и источника 5 света, располагаетс так, что при определенном положении отражател 2 луч от источника света падает на фотосопротивление 4, включенное в цепь исполнительного реле. Интервал времени мигани источника света задают с помощью контактов 6, периодически замыкаемых ма тником 7. Луч от источника света может -попасть на фотосопротивление 4 лишь при .перекрытии их отражателем 2, причем источник света загораетс толькоOn the shaft axis /, the rotational speed of which is controlled, the reflector 2 and the flag 5 rotating with the shaft are attached. 4, included in the executive relay circuit. The time interval of the blinking of the light source is set with the help of contacts 6, periodically closed by an antenna 7. The beam from the light source can hit the photoresistance 4 only if it is overlapped by their reflector 2, and the light source only lights
