1. Products Overview

Harmonic reducer is a mechanical transmission device that uses the principle of harmonic transmission and low noise. Its internal structure consists of a flexible skeleton and a rigid gear. The working principle of the harmonic reducer is to use the elastic deformation of the flexible skeleton and the meshing of the gear to achieve a high-precision input shaft speed to the deceleration and reverse transmission of the output shaft speed. Harmonic reduction is characterized by high transmission accuracy, low noise, fast response speed, and good reliability.

Harmony reducer plays an important role in the mechanical transmission system, including the following aspects:

Speed reduction: Harmonic reducer can reduce the high input speed rotating into low speed rotation through the principle of harmonic transmission, thereby reducing the speed of mechanical equipment.

Reverse transmission: Harmonic reducer has reverse transmission capabilities, which can achieve reverse transmission of the output shaft torque during the deceleration;

High precision transmission effect: The harmonic reducer uses the combined structure of flexible skeleton and rigid gear, which can achieve the accurate conversion of high precision input shaft speed to the output shaft speed;

Low noise effect: The internal structure of the harmonic reducer is simple and stable, which can effectively reduce noise and vibration.

PRMCAS Harmonic Gear Reducers Features and Advantages as the followings,

The transmission ratio is larger. The ratio of a single-stage harmonic gear transmission rate is 70 ~ 320:1, can reach up to 1,000:1 in certain harmonic reducers, and the multi-stage transmission speed ratio can reach more than 30,000:1.

High carrying capacity. This is because the number of teeth that meshing at the same time in the harmonic gear transmission can be more than 30% of the total number of teeth at the same time, and the soft wheels use high-intensity materials, and the tooth is connected with facial contact.

High transmission accuracy. This is because the number of teeth in the harmonic gear transmission at the same time and, the multi-tooth mesh has a mutual compensation effect on the error, so the transmission accuracy is higher. In the case of the same gear accuracy level, the transmission error is only about 1/4 of ordinary cylindrical gear transmission.

High drive efficiency and stable exercise. Because the soft wheel teeth moved a uniform radial movement during the transmission, even if the input speed is very high, the relative slip speed of the wheel teeth is still extremely low. So the wheel's teeth wear is small, high efficiency (can reach 69%~ 96%). Due to the entry and meshing, both sides of the gear participated in the work, so there was no impact, and the exercise was stable.

Simple structure, small number of parts, and convenient installation. There are only three basic components, and the input and output shaft coaxial rays, so the structure is simple and easy to install.

Small volume and light weight. Compared with the regular reducer, when the output torque is the same, the volume of the harmonic gear reducer can be reduced by 2/3, and the weight can be reduced by 1/2.

Suitable for closed space application. Using the flexible characteristics of soft wheels, this valuable advantage of rotation is incomparable to other transmission.
