In the field of modern mechanical transmission, harmonic reducer, with its unique flexible transmission principle, has shown a series of characteristics superior to traditional reducer. It not only performs well in transmission efficiency, precision, load-bearing capacity, but also has significant advantages in compact structure and convenient installation.Harmonic reducer adopts the transmission principle of flexible gears, which makes its energy loss relatively small during transmission. Compared with traditional rigid gear transmission, harmonic reducer reduces the friction and wear caused by gear meshing, thereby improving transmission efficiency. This means that under the same input power, harmonic reducer can output greater effective power, so that mechanical equipment can use energy more efficiently during operation.Harmonic reducer also has significant advantages in transmission accuracy. Since there are more teeth meshing at the same time in harmonic transmission, the error averaging effect is significant, so the transmission accuracy is higher. Under the same gear accuracy level, the transmission error of harmonic reducer is only about one-fourth of that of ordinary cylindrical gear transmission. This high-precision transmission characteristic makes the harmonic reducer have a wide range of application prospects in occasions that require precision control, such as industrial robots, precision measuring instruments, etc.In addition to the advantages in transmission efficiency and precision, the harmonic reducer also has a high load-bearing capacity. This is because the harmonic gear transmission has a large number of teeth meshing at the same time, and the flexible wheel is made of high-strength materials, and the teeth are in surface contact, which improves the load-bearing capacity. This enables the harmonic reducer to withstand large radial and axial loads and is suitable for applications under various heavy loads and complex working conditions.The compact structure, small size and light weight of the harmonic reducer are also one of its significant advantages. Since the harmonic reducer adopts a transmission structure with three basic components (rigid gears, harmonic generators and flexible gears), its overall structure is more compact. Compared with traditional reducers, the volume of the harmonic reducer can be reduced by two-thirds and the weight can be reduced by more than half when the output torque is the same. This compact structure and small size make the harmonic reducer more convenient during installation and use, saving space and reducing costs.In addition, the harmonic reducer also has the advantages of large transmission ratio, smooth movement and low noise. The speed ratio range of single-stage harmonic gear transmission can reach 70 to 320, and the speed ratio of multi-stage transmission can reach more than 30,000. This large transmission ratio makes the harmonic reducer have a wide range of application value in occasions where deceleration or acceleration is required. At the same time, since the deformation of the flexible wheel in the harmonic drive is uniform, the movement is smooth, there is no impact phenomenon, and the noise is relatively low.In summary, the harmonic reducer has significant advantages in transmission efficiency, precision, load-bearing capacity, compact structure, etc. with its unique flexible transmission principle. These advantages make the harmonic reducer have broad application prospects and important strategic value in the fields of industrial robots, precision measuring instruments, aerospace, etc.
