Description
первоначальный момент отстает, а ведущий вал, обгон маховик, выдвигает эксцентриковым кулачком 7 толкатель 5, отклон ющий рычаг 11, взаимодействующий с кнопкой выключател 13 (ВЗ), который обесточен, и происходит холостое срабатывание выключател закрыти (ВЗ) и электродвигатель не отключаетс .the initial moment lags behind, and the drive shaft, overtaking the flywheel, pushes the eccentric cam 7 pusher 5, the deflecting lever 11, which interacts with the switch button 13 (EOI), which is de-energized, and the idle time of the closing switch (EOI) occurs and the motor does not turn off.
По дости кении конечного положени привода в сторону открыти начинаетс торможение ведущего вала 2, при этом в силу инерционности чашеобразный маховик 3 проворачиваетс на валу до упора н эксцентрик 7 выдвигает толкатель 5, отклон ющий рычаг 10, взаимодействующий с выключателем открыти 12, отключающим питание электродвигател .Upon reaching the end position of the drive towards the opening, braking of the drive shaft 2 begins, and due to the inertia, the cup-shaped flywheel 3 rotates on the shaft until it stops and the eccentric 7 pushes the pusher 5, the deflecting lever 10, which interacts with the switch 12, which turns off the power of the electric motor.
В случае подключени электродвигател неправильно ведущий вал 2 начинает вращатьс В сторону закрыти и эксцентриковый привод выдвигает толкатель 5, отклон ющий рычаг 10, взаимодействующий с выключателем открыти 12, который разрывает цепь питани электродвигател .If the motor is connected incorrectly, the drive shaft 2 begins to rotate towards the closing and the eccentric drive pulls the pusher 5, the deflecting lever 10, which interacts with the switch 12, which breaks the motor power supply circuit.
При пуске привода в сторону закрыти кнопкой КЗ цикл операций, описанные выше,When starting the drive in the direction of the short-cut button, the cycle of operations described above,
повтор етс в том же пор дке, только во взаимодействие вступают другие пары толкателей , рычагов и выключателей.repeats in the same order, only other pairs of pushers, levers and switches come into play.
