Main functions and working conditions
The device is used to drive the sliding gates, with the moving speed of 12 meters per minute, EX5 gate operator is
Powered by AC 22OV, 50 Hz. It is featured with powerful starting strength, capable of overload at short time.
When it is overload, it is protected electrically and mechanically. In case of power failure, a key can be used to
release. The device and move the gates manually. The device can be installed indoors or outdoors.
Working principle and main structure
The size of the out appearance can be seen in Fig. 1.
The device is composed of a single phrase motor, worm and worm gear. The main shaft of the motor rotates the
worm by the clutch, the worm rotates the worm gear and output gears, which push the racks attached to the
sliding gates, thus makes the gates slide.
The structure of the motor and worm is shown in Fig. 2.
Accounting to the weight of the gates and the safety function, the pressure screws can be adjusted. Either
pressing or releasing the springs, to produce a small axial motion by the clutch plate at the end of the motor,
resulting in the change the pressure between the clutch plate and the output strength as well.
The structure of the worm gear components is shown in Fig. 3.
They consist of a pair of high intensity plastic gear clutch, which can be geared to move the gate by motor. If the
clutch is released by key, the gates can be moved manually.
The device is well cooled by the cooling oil, which fills the whole device, including the stator, the rotator of the
motor, the worm gear and the worm. The electric controller of the device is installed a time delay equipment, the
delay time should be more 5
seconds than gate moving time.
