The function of the reduction gearbox in electric actuators
Thread Content
I’m hoping experts can help explain this: in the renovation projects I’ve been working on recently, some of the original slurry electric valves come equipped with reduction gears, and these are available in DN100 and DN200 sizes. I wonder if the use of reduction gears on such small valves is intended to reduce the cost of the electric actuators Should a valve with high torque be operated by an actuator with low torque? Also, there are various names for gearboxes; does \"worm gear\" refer to this type of gearbox?
The function of the reduction mechanism is to reduce the speed of the high-speed rotating motor to the speed required to drive the valve, and to amplify the motor’s output torque according to the reduction ratio.
Then, for those actuators that do not have a reduction mechanism, must the speed of the selected motor be matched to the moving speed of the valve?
So, once the model of the gearbox is chosen, can the actual reduction ratio still be adjusted? Could we reduce the gear ratio a bit more?
