Description
танавливаетс на плате 19 в фиксированном положении.is pushed on board 19 in a fixed position.
Устройство работает следующим образом.The device works as follows.
После установки перфокарты 21 поворачиваютс ручки управлени 17 вниз до упора. При этом вращение передаетс через вал 16 и зубчатые колеса 9, 18 шайбам 10 и собачкам 11, которые в конце хода заскакивают за зубь храповых колес 13, осуществл их «захват.After installing the punch card 21, the control knobs 17 are turned down as far as they will go. In this case, the rotation is transmitted through the shaft 16 and the gears 9, 18 to the washers 10 and the pawls 11, which at the end of the stroke drop into the teeth of the ratchet wheels 13, making them "grip."
При обратном повороте ручек управлени 17 вверх до упора собаЧКИ И привод т во вращение храповые колеса 13 и с ними передние эксцентриковые оси 5, а также с помощью т г 14 и поводков 15 - задние эксцентриковые оси. Это заставл ет перемещатьс плату 6 в направлении платы 19. В конце поворота ручек управлени 17 платы максимально сближаютс и скольз щие контакты 7 начинают контактировать через отверсти в перфокарте с ламел ми платы 19. На чертеже {разрез В-В) это положение точки контактировани обозначено буквой Д, штрих-пунктирной линией обозначена траектори рабочей точки скольз щего контакта 7, стрелками указано направление движени . Дл перевода платы 6 в исходное положение необходимо проделать с помощью ручек управлени 17 те же операции, т. е. сначала повернуть их вниз до упора, затем вверх до упора. При этом повтор етс цикл работы механизма с той лишь разницей, что платы 6 и 19 удал ютс одна от другой.When the control knobs 17 are turned back up to the dog's stop, the ratchet wheels 13 and the front eccentric axles 5, and also with the help of tg 14 and drivers 15 - rear eccentric axes, rotate. This causes the board 6 to move in the direction of the board 19. At the end of the rotation of the control knobs 17 of the board as close as possible and the sliding contacts 7 begin to contact through the holes in the punch card with the lamellae of the board 19. In the drawing {section b-B), this position of the contact point is indicated the letter D, the dash-dotted line indicates the trajectory of the operating point of the sliding contact 7, the arrows indicate the direction of motion. To bring the board 6 to the initial position, it is necessary to perform the same operations using the control knobs 17, i.e., first turn them down as far as they will go, then upwards as far as they will go. This repeats the cycle of operation of the mechanism with the only difference that the boards 6 and 19 are removed from one another.
