Harmonic reducer-the characteristics of harmonic reducer can not be replaced

2023-09-11

In ensuring that the motor runs at a suitable speed, the motor speed can be accurately reduced to the speed required by the equipment, and the rigidity of the mechanical body can also be improved while outputting greater torque. This is the effect of ordinary reducers. Choose harmonic reducer, so what characteristics can not be replaced by harmonic reducer? Today, the harmonic reducer manufacturer will introduce to you the characteristics that the harmonic reducer cannot be replaced. Let's take a look. The harmonic reducer manufacturer said that the flexible gear teeth make uniform radial movement during the transmission process. Even if the input speed is very high, the relative slip speed of the gear teeth is still extremely low (-% of that of the ordinary involute gear transmission). Therefore, the gear teeth wear is small and the efficiency is high (up to 70% ~ 95%).

Since both sides of the gear participate in the work when engaging in and engaging out, there is no impact phenomenon and the movement is stable. Harmonic drive can transmit motion to the confined space by using the flexible feature of flexible wheel, which is incomparable to other drives. The main function of harmonic reducer is to reduce the speed and increase the torque while ensuring that the equipment can reliably complete the process tasks, when repeating the same action, the positioning accuracy and repeated positioning accuracy of the process can be ensured. The harmonic reducer manufacturer tells you that compared with the ordinary reducer, when the output torque is the same, the volume of the harmonic reducer can be reduced by 2/3 and the weight can be reduced by 1/2. There are only three basic components: wave generator, flexible wheel and rigid wheel, and the input and output shaft are coaxial, so the structure is simple and the installation is convenient.

The speed ratio of single-stage harmonic gear transmission ranges from 69 to 330, which can reach 990 in some devices, and the speed ratio of multi-stage transmission can reach more than 31000. In the process of harmonic gear transmission, the number of teeth meshing simultaneously in double-wave transmission can reach more than 30% of the total number of teeth. The flexible gear adopts high-strength materials, and the teeth are in surface contact with each other. In harmonic gear transmission, the number of teeth meshing at the error is averaged, that is, multi-tooth meshing has a mutual compensation effect on errors, so the transmission accuracy is high. The harmonic reducer manufacturer leaks that under the condition of the same gear accuracy level, the transmission error is only about 1/4 of that of ordinary cylindrical gear transmission. At the same time, the radius of the wave generator can be changed slightly to increase the deformation of the flexible wheel, so that the backlash is very small, and even the backlash-free meshing can be achieved. Therefore, the transmission of the harmonic gear reducer is small and suitable for reverse rotation.
