Compared with the motor, the output is greater, so the output shaft of the reducer is more likely to be broken. The greater the error of the concentricity between the two, the shorter the time for the output shaft of the drive motor to break. However, if the assembly is not concentric, there will be no match or gap between the contact surfaces, there will be radial force and space for deformation. When it is not concentric, the output shaft of the drive motor also bears the radial force (bending moment) from the input end of the reducer. Planetary reducers are generally used when Cycloidal Gear Reducer is required in a limited space, that is, small size and large torque, and its reliability and life are better than spur gear reducers. Spur gear reducers are used for lower current consumption, low noise and high efficiency and low cost applications.. It is generally used for low-speed and high-torque transmission equipment.Servo reducer is another term for 'planetary reducer' in the industry. The principle is to pass electric motors, internal combustion engines, motors or other high-speed running power through the input shaft of the reducer The gear with a small number of teeth on the gear meshes with the large gear on the output shaft to achieve the purpose of deceleration. The characteristics of the planetary reducer are small size, large output torque, high transmission efficiency, as long as these requirements are available, cutting machines, pipe benders, bucket wheels, cement production lines, grease processing, fertilizers, power plants, cement, glass Many industries will use planetary reducers. The servo reducer has a relatively compact structure, small return clearance, high precision, long service life, and a large rated output torque. But the price is slightly more expensive
