The speed reducer has the function of protecting the electric motor in the transmission. During procedure, the gearbox can be exposed to a large torque. When the overload is certainly sent to the motor, just the overload quantity is divided by the Taper Pulleys reduction ratio. If it is certainly straight borne by the engine, the electric motor may be damaged. When the overload is normally very huge, the deceleration opportunity is certainly damaged initial, and the speed reducer can be utilized only after changing the spare parts. The price is usually relatively low. If the motor is definitely straight damaged, the maintenance is usually relatively sluggish and the price is certainly high.

Adding a gearbox can decrease the moment of inertia, generally the square of the rate ratio is definitely reduced, which usually is normally extremely important meant for control, and can easily control the start and quit and moving in period. Increasing the torque through the speed reducer is normally similar to increasing the insight power, which can reduce the power required to input the electric motor (in the case where velocity regulation is normally required). Generally, the engine is more costly than the gear reducer, so consider using a gear reducer. The working rule of the gearbox varies based on the type of reducer. At present, the overall performance of the reducer is supposed to be to the Tomas planetary equipment gearbox. The transmission system of the planetary gear gear box can be a equipment. The framework diagram is not attracted, it can be extremely simple. Visualize having two large and one little circles, two circles concentric, and three other small circles in the band part between the two circles. The largest one of all the circles is certainly the inner ring gear, and the other four small circles are gears. The middle one is normally called the sunlight wheel, and the other three little rounds are called the planetary wheel. The servo motor pushes the sun equipment of the reducer, and the sunlight gear runs the planetary gear backed on the inner ring gear. The planetary equipment transmits the meshing transmission with the outer ring equipment to drive the output shaft linked to the outer ring equipment to accomplish the deceleration. Purpose, the reduction ratio is related to the specs of the gear train. As for the selection, it is usually related to the kind of servo engine utilized and the technical requirements in the program.
