The harmonic reducer is composed of a fixed internal gear rigid wheel, a flexible wheel, and a wave generator that makes the flexible wheel radially deform. The harmonic gear reducer is a new type of transmission structure in the gear reducer. It uses the flexible gear to generate a controllable elastic deformation wave, which causes the teeth of the rigid wheel and the flexible wheel to be relatively misaligned to transmit power and motion.

This kind of transmission is essentially different from general gear transmission, and has particularity in meshing theory, set calculation and structural design. The harmonic reducer has the advantages of high precision and high bearing capacity. Compared with the ordinary reducer, its volume and weight are reduced by at least 1/3 due to the use of 50% less materials.
1. Use good materials, generally use various high-quality alloy steel forgings, and improve the quality control level of materials and heat treatment.
2. The theoretical knowledge is becoming more and more perfect and closer to reality (such as gear strength calculation method, modification technology, deformation calculation, optimization design method, smooth transition of tooth root, new structure, etc.).
3. The structure design is more reasonable.
4. The machining accuracy is improved to ISO5-6 level.
5. The bearing quality and life are improved.
6. The quality of lubricating oil is improved.
