Description

(54) УСТРОЙСТВО ДЛЯ ПОВОРОТА РАБОЧИХ ЛОПАТОК ОСЕВОГО ВЕНТИЛЯТОРА(54) DEVICE TO TURN THE WORKBOX OF AXIAL FAN

с хвостовиками 2 и при помощи тросов 6 синхронизируетс  поворот всех лопаток 3.with the shanks 2 and with the help of the cables 6, the rotation of all the blades 3 is synchronized.

Таким образом, размещение гидроцилиндров 1 на внутренней стороне втулки 4 позвол ет значительно уменьщить длину Хвостовиков лопаток, увеличить размеры гидроцилиндров, снизив при этом давление регулирующей среды, что в свою очередь позвол ет выполнить гидроцилиндры более тонкостенными, вследствие чего снижаетс  вес рабочего колеса.Thus, placing the hydraulic cylinders 1 on the inner side of the sleeve 4 significantly reduces the length of the blade tails, increases the size of the hydraulic cylinders, reducing the pressure of the regulating medium, which in turn allows the hydraulic cylinders to be thinner, thereby reducing the weight of the impeller.

Кроме того, ввиду возможности увели чени  размеров гидроцилиндров и повышени  тем самым создаваемого ими усили , количество гидроцилиндров можно уменьшить , что также способствует уменьшению веса и упрощеншо конструкции рабочего колеса .In addition, due to the possibility of increasing the size of the hydraulic cylinders and thereby increasing the force created by them, the number of hydraulic cylinders can be reduced, which also contributes to weight reduction and simplification of the impeller design.
