Description

тор 8, воздействующий при вращении зубчатого колеса 5 на каждую коническую шестерню 4 последовательно. Ступицы конических шестерен 4 снабжены фиксаторами 9, взаимодействующими с сектором-фиксатором 10, выполненным на торцовой поверхности зубчатого колеса 5 на различных диаметральных уровн х с коническим зубчатым сектором 8.torus 8, acting during the rotation of the gear wheel 5 on each bevel gear 4 in series. The hubs of the bevel gears 4 are provided with clamps 9, which interact with the sector-lock 10, made on the end surface of the gear wheel 5 at different diametrical levels with the bevel gear sector 8.

Устройство работает следующим образом.The device works as follows.

Реверсивный электропривод 7 через шестерню 6 приводит во вращение зубчатое колесо 5 и вместе с ним конический зубчатый сектор 8 и сектор-фиксатор 10. За один оборот зубчатого колеса 5 конический зубчатый сектор 8 поворачивает последовательно каждую коническую шестерню 4 на одинаковый угол. Через резьбовое соединение с винтовыми стержн ми 3 прерывистое вращение каждой конической щестерни 4 преобразуетс  в поступательное прерывистое движение задвижек I, измен ющих ири этом проходное сечение проточной части и, следовательно, давление перерабатываемого продукта.A reversible electric actuator 7 through gear 6 drives the gear 5 and the conical gear sector 8 and the latch sector 10 to rotate. During one revolution of the gear 5, the conical gear sector 8 rotates each bevel gear 4 in succession at the same angle. Through the threaded connection with the screw rods 3, the discontinuous rotation of each conical gear 4 is converted into a continuous intermittent movement of the valves I, changing or this changing the flow area of the flow part and, consequently, the pressure of the product being processed.

В момент зацеплени  конического сектора 8 с одной из конических шестерен 4 остальные конические щестерни 4 удерживаютс  в статическом положении, необходимом дл  надежной работы устройства, с помощью фиксаторов 9 на ступицах конических шестерен 4, рабочие поверхности которых располагаютс  в этот момент напротив поверхности секторафиксатора 10. При каждом последующем обороте зубчатого колеса 5 (конического сектора 8 и сектора-фиксатора 10) весь цикл прерывистого движени  конических шестерен 4 и задвижек 1 повтор етс . Полное линейное перемещение каждой задвижки 1 в пазах корпусаAt the moment of engagement of the bevel sector 8 from one of the bevel gears 4, the remaining bevel gears 4 are held in a static position necessary for reliable operation of the device, using clamps 9 on the hubs of bevel gears 4, whose working surfaces are at this moment opposite the surface of the sector fixator 10. with each subsequent revolution of the gear wheel 5 (bevel sector 8 and locking sector 10), the entire cycle of intermittent movement of bevel gears 4 and valve 1 is repeated. Full linear movement of each gate valve 1 in the housing grooves

2 определ етс  кинематическими соотношени ми в звень х устройства.2 is determined by the kinematic relationships in the units of the device.

Такое выполнение устройства упрощает его конструкцию, снижает крут щий момент на приводном валу исполнительного механизма, следовательно, уменьшает габариты и металлоемкость устройства при одинаковых услови х его применени , упрощает его изготовление , а также обеспечивает надежную работу при непрерывных и периодических процессах переработки продуктов в черв чных машинах.Such an embodiment of the device simplifies its design, reduces the torque on the drive shaft of the actuator, therefore, reduces the size and intensity of the device under the same conditions of its use, simplifies its manufacture, and also ensures reliable operation during continuous and periodic processing of products in the worm machines.
