The gear box has the function of protecting the motor in the transmission. During procedure, the gearbox can be put through to a huge torque. When the overload can be transmitted to the engine, only the overload quantity is certainly divided by the decrease ratio. If it is normally straight paid for by the electric motor, the motor may end up being broken. When the overload is definitely very huge, the deceleration opportunity is definitely broken 1st, and the gear reducer can be used only after changing the extra parts. The price can be fairly low. If the electric motor is Super Power Lock usually straight damaged, the maintenance is usually relatively sluggish and the price is certainly high.
Adding a gearbox can reduce the second of inertia, generally the block of the speed ratio is definitely decreased, which can be very important meant for control, and can easily control the start and end and shifting in period. Raising the torque through the gear reducer is definitely comparable to raising the insight power, which can decrease the power required to insight the engine (in the case where acceleration legislation is usually needed). Generally, the electric motor is usually even more costly than the reducer, so consider utilizing a reducer. The functioning rule of the reducer varies based on the type of gear box. At present, the performance of the gear reducer is supposed to be to the Tomas planetary equipment speed reducer. The transmission system of the planetary gear speed reducer is usually a gear. The framework diagram is not really drawn, it is usually extremely basic. 
Imagine having two huge and one small circles, two circles concentric, and three additional little circles in the band portion between the two circles. The largest one of all the circles is definitely the inner ring equipment, and the various other four little circles are gears. The middle one is usually called the sun wheel, and the additional three little rounds are known as the planetary wheel. The servo motor memory sticks the sunlight equipment of the gearbox, and the sun gear pushes the planetary equipment backed on the internal band gear. The planetary gear transmits the meshing transmitting with the outer ring equipment to drive the output shaft connected to the outer band equipment to accomplish the deceleration. Purpose, the decrease ratio is certainly related to the specifications of the equipment train. As for the selection, it is certainly related to the type of servo engine used and the technical requirements in the application.
