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 gear 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. When the harmonic reducer is assembled, impurities enter it due to various irregular factors, which will affect its accuracy and service life. How to prevent impurities from entering the harmonic reducer?
1. Improve the environment of the assembly workshop and use a dust-free workshop for assembly;
2. The burrs and other impurities should be cleaned up during processing;
3. When placing lubricating grease, please check whether there are impurities entering the grease;
4. Assembly personnel should pay attention to wearing rubber gloves during assembly to prevent dust and impurities from being brought in;
5. When using thread glue or flat glue, check whether there are impurities brought in.
When assembling the harmonic reducer, pay attention to prevent dust impurities from being brought in, so as to ensure its accuracy and prolong its service life. Harmonic gear reducers are widely used in aviation, aerospace, energy, navigation, shipbuilding, bionic machinery, commonly used ordnance, machine tools, instruments, electronic equipment, mining and metallurgy, transportation, lifting machinery, petrochemical machinery, textile machinery, agricultural machinery and medical Equipment and other aspects are increasingly widely used, especially in the servo system with high dynamic performance, the use of harmonic gear transmission shows its superiority. The power it transmits ranges from tens of watts to tens of kilowatts, but high-power harmonic gear drives are mostly used in short-term work situations.
