Description

Известные пневматические кулисно-храповые приводы, примен емые , например, в электровозах дл  осуществлени  прерывистого вращательного движени  главного вала переключател  ступеней трансформатора , выполн ютс  в виде храпового колеса, взаимодействующего с помощью двуплечей собачки с центрально расположенным рычагом , снабженным подпружиненной защелкой.The known pneumatic ratchet-ratchet drives used, for example, in electric locomotives to carry out an intermittent rotational movement of the main shaft of the transformer step switch, are made in the form of a ratchet wheel interacting by means of two shoulders of a centrally located doggie fitted with a spring-loaded latch.

Недостатком этих приводов  вл етс  ненадежность их включени  и больша  величина холостого хода.The disadvantage of these drives is the unreliability of their inclusion and the large amount of idling.

Привод, выполненный согласно изобретению, лишен этого недостатка . Сущность изобретени  заключаетс  в том, что привод снабжен двум  неподвижными упорами, которые взаимодействуют со скошенными поверхност ми конца собачки.A drive made according to the invention is free from this disadvantage. The essence of the invention is that the drive is provided with two fixed stops that interact with the beveled surfaces of the end of the pawl.

На чертеже схематически изображен предложенный привод.The drawing schematically shows the proposed drive.

Два одинаковых цилиндра / соединены с воздушной магистралью и атмосферой посредством одинаковых электромагнитных вентилей 2. Один цилиндр крепитс  непосредственно к корпусу 3 привода, а другой - к корпусу 4, в котором помещена пружина. Шток 5, снабженный двум  поршн ми, в своей средней части через кулисный механизм соедин етс  с рычагом 6. Пружина 7 служит дл  возвращени  штока в исходное положение после выпуска воздуха из рабочих полостей ци-линдров .Two identical cylinders / are connected to the air line and the atmosphere by the same electromagnetic valves 2. One cylinder is attached directly to the actuator housing 3, and the other to the housing 4 in which the spring is placed. The rod 5, equipped with two pistons, is connected in its middle part to the lever 6 through the rocker mechanism. The spring 7 serves to return the rod to its initial position after air has been released from the working cavities of the cylinders.

Храповое колесо 8 жестко крепитс  на главном валу привода. Двухсторонн   собачка 9, сид ша  на валике 10 рычага 6, фиксируетс  защелкой 11. Собачка имеет скошенные поверхности в, которыми она взаимодействует с неподвижными упорами 12. В нейтральном (среднем) положении собачка не сцепл етс  с зубь ми храпового колеса . Дл  вращени  главного вала переключател  по. часовой стрелкеThe ratchet wheel 8 is rigidly mounted on the main drive shaft. A double-sided pawl 9, seated on a roller 10 of the lever 6, is fixed by a latch 11. The pawl has beveled surfaces in which it interacts with fixed stops 12. At the neutral (middle) position, the pawl does not engage with the teeth of the ratchet wheel. To rotate the main shaft of the switch. clockwise
