The gear reducer has the function of protecting the motor in the transmission. During operation, the gear reducer is Cycloidal Gearboxes usually exposed to a large torque. When the overload can be sent to the engine, just the overload amount is divided by the reduction ratio. If it is straight borne by the engine, the engine may become broken. When the overload is very large, the deceleration opportunity can be damaged first, and the gear box can be utilized only after replacing the extra parts. The price is certainly relatively low. If the motor is usually directly damaged, the maintenance is normally relatively slow and the price is high.
Adding a reducer can reduce the moment of inertia, generally the square of the rate ratio is decreased, which usually is usually very important intended for control, and can control the start and prevent and shifting in time. Increasing the torque through the reducer can be comparable to raising the input power, which can decrease the power required to insight the motor (in the case where acceleration rules is usually required). Generally, the engine is definitely even more costly than the gear reducer, therefore consider utilizing a speed reducer. The working basic principle of the gear reducer varies based on the type of speed reducer. At present, the overall performance of the reducer goes to the Tomas planetary equipment gear box. The transmitting mechanism of the planetary gear speed reducer can be a equipment. The framework diagram is definitely not really drawn, it is very basic. Picture having two large and one small circles, two circles concentric, and three additional little circles in the ring part between the two circles. The largest one of all the circles is definitely the inner band equipment, and the additional four little circles are things. The middle one is definitely known as the sunlight wheel, and the additional three little rounds are called the planetary wheel. 
The servo motor turns the sun gear of the gear box, and the sun equipment pushes the planetary gear backed on the internal band gear. The planetary equipment transmits the meshing transmitting with the outer band gear to drive the output shaft connected to the outer ring equipment to achieve the deceleration. Purpose, the reduction ratio is usually related to the specifications of the gear teach. As for the selection, it is usually related to the kind of servo electric motor used and the technical requirements in the application.
