If we have started to learn about harmonic gear drives, we will know that it is a power harmonic drive device. It is called harmonic drive because the flexible part will be deformed by force during its operation and there will be harmonics. When understanding the relevant information of the harmonic gear drive, we must understand what the characteristics of the harmonic gear drive are.

In fact, harmonic gear drives have many characteristics. As we all know, the harmonic gear transmission can be used as a power source, but if we study carefully, we will find that the harmonic gear transmission can be used as a speed increasing device or a reduction device. The energy provided can accomplish many tasks, so they can play a role in many situations.

1. The transmission ratio of the harmonic gear transmission device is very large

Although the harmonic gear transmission has such a high transmission ratio, its volume is usually relatively small, and the number of parts constituting it is relatively small, making the harmonic gear transmission possible. With convenient installation, simple maintenance, and small volume of the harmonic drive, it has high work efficiency, basically between 92% to 96%.

2. The carrying capacity of the harmonic drive transmission is very high

Because the inner flexible wheel and the steel wheel are meshed together by multiple teeth, this makes the wear surface of the gear more uniform during the working process, and there will be no damage. The gap between the two gears can also be adjusted. When the torsional rigidity of the flexible wheel is large, high-precision matching can be achieved between the two gears driven by the harmonic gear. In the process of harmonic gear transmission, the power transmission between the sealed space and the external environment can be realized.

It is precisely because the harmonic gear drive has so many characteristics, it can have such a wide range of applications. People should learn more details about it.
