Introduction to the advantages of harmonic reducers

Harmonic reducer, harmonic gear drive (harmonic drive for short), applied disciplines: mechanical engineering (first-level discipline); transmission (second-level discipline); gear transmission (third-level discipline) Harmonic gear transmission reducer uses planetary A new type of reducer developed from the principle of gear transmission. The following is an introduction to the advantages of harmonic reducers: 1. High reduction ratio 　Single-stage coaxial can obtain a high reduction ratio of 1/30 to 1/320. The structure and structure are simple, but it can realize a high reduction ratio device. 2. Small backlash 　Different from the meshing with ordinary gears, the backlash is extremely small. This feature is an indispensable element in the field of controllers. 3. High precision Multi-tooth meshing at the same time, and two 180-degree symmetrical gear meshing, so the gear pitch error and accumulated pitch error have an even effect on the rotation accuracy, so that the position accuracy and rotation accuracy reach a very high level.  4. Few parts and easy installation The three basic components achieve a high reduction ratio, and they are all on the same axis, so the kit is easy to install and simple in shape. 5. Small size and light weight 　　Compared with the conventional gear unit, the volume is 1/3, the weight is 1/2, but it can obtain the same torque capacity and reduction ratio, realizing small size and light weight. 6. High torque capacity 　　The material of the flexible wheel uses special steel with high fatigue strength. Unlike ordinary transmissions, the number of teeth meshed at the same time accounts for about 30% of the total number of teeth, and it is in surface contact, so the pressure on each gear is reduced, and a high torque capacity can be obtained. 7. High efficiency 　The sliding of the gear tooth meshing part is very small, which reduces the power loss caused by friction. Therefore, while achieving a high reduction ratio, it is possible to maintain high efficiency and realize the miniaturization of the drive motor. 8. Low noise The meshing speed of the gear teeth is low, and the transmission force is balanced, so the operation is quiet and the vibration is extremely small.
