1. The main characteristics of worm gear reducer is with reverse self-locking function, can have a large reduction ratio, input shaft and output shaft is not on the same axis, not on the same plane. But the general volume is large, the transmission efficiency is not high, the accuracy is not high.

        2. Harmonic reducer harmonic transmission is the use of flexible components controllable elastic deformation to transfer motion and power, small volume, high precision, but the disadvantage is that the flexible wheel life is limited, impact resistance, rigidity and metal parts are poor. The input speed should not be too high.
        3. The planetary reducer has the advantages of relatively compact structure, small return clearance, high accuracy, long service life, rated output torque can do a lot. But it's a little more expensive. According to the working principle of speed reducer reducer are different difference, as the current performance better to belong to the planetary gear reducer, planetary gear reducer gear transmission mechanism is, need not draw the structure diagram, is very simple, just imagine there are two circles, one large and one small two concentric circle, between two circular ring part has three other small round, The largest of all circles is the inner ring. The other four small circles are cogs. The middle one is called the sun wheel, and the other three are called the planet wheel. The servo motor drives the sun wheel of the reducer, and the sun wheel drives the planet wheel supporting the inner tooth ring. The planet wheel drives the output shaft connected with the outer tooth ring through its meshing transmission with the outer tooth ring, so as to achieve the purpose of deceleration. The reduction ratio is related to the specifications of the gear system. The selection is related to the type of servo motor used and the technical requirements in the application.
