There is no doubt that the harmonic reducer is one of the key parts of the intelligent robot.

Nowadays, intelligent robots are used in various fields in the market. The precision and characteristics of the entire equipment of intelligent robots greatly endanger the high efficiency and quality of manufacturing. Therefore, the precision and characteristics of harmonic reducers are also particularly important. As a leading enterprise company of intelligent robot harmonic reducers in my country, China Research Pulse Current Independent Products has developed a technology-leading harmonic reducer, striving for the most international standard, and taking an important step in grasping key technologies of Chinese artificial intelligence.

In the whole process of application of intelligent robots, vibration problems are very prone to occur. The daily tasks for the precision of fitness exercises are relatively high. Mild vibrations cause the precision of intelligent robots to be reduced. The wave reducer essentially handles the vibration coupling problem. According to Chu Jianhua's detailed introduction, the extremely high-precision harmonic reducer of Y series products has the precision of 10 arc-second transmission system, which is the highest level in the world at this stage, avoiding the vibration problem from the lowest hardware equipment.

On the other hand, under the condition that the precision is not changed, improving the service life of the reducer is the key reference. The long-life harmonic reducer of Zhongyan pulse current N series products maintains the precision beyond 20,000 hours, and has achieved the most international level. In terms of quality design, the N series harmonic reducer expands the inclination of the gear teeth, Chu Jianhua expressed, which means that it can bear greater torque, and the invalidation of rupture is greatly reduced. He believes that the most critical thing of the reducer is to design the adjustment teeth based on different manufacturing industries, to have in-depth discussions with customers, to explore work experience, to continuously improve, and to develop customized design solutions and development designs from the roots.

Zhongyan Pulse Current has formulated two solutions on the lowest level of hardware equipment. One is a customized special paired motor and a long-life harmonic reducer, and the other is an integrated pulse current speed reduction group. From the perspective of Chu Jianhua, the scale of the machinery manufacturing industry is not large, and ordinary electrical appliance manufacturers do not want to do technical and professional matching integrated design solutions. Therefore, Zhongyan Pulse Current Fund has invested three years to develop and design the lowest-level motor. Deal with the problems that customers actually have.

At the level of the integrated pulse current speed reduction group, it is not enough to simply imagine "1+1" as a hardware device. The integration must be designed, produced, processed, assembled, and inspected. Chu Jianhua expressed that at the beginning, there were many noise and vibration problems. After the detection was improved, the problem of pairing of different hardware devices was dealt with, which greatly reduced vibration and noise, increased the service life of the entire device, maintained inertial pairing, and reduced Radial and axial tremors reduce different shaft degrees; and use the same structure to reduce unit size and net weight.

To maintain the high-precision assembly line in the integrated design scheme, it is necessary to improve the tolerance fit and the dimensional chain. Chu Jianhua feels that many items cannot be certified immediately and must be adjusted according to continuous test exploration. Therefore, Zhongyan Pulse Current carries out a lot of testing work. To improve and constantly check. For precision machinery manufacturing, the regulations are more stringent, and some continue to run continuously for more than 1,000 hours, and some must continue to improve when working in a natural environment with a limit of 100°C.

Full-step closed-loop control quality control

Chu Jianhua also introduced in detail the reasonable layout of the research and development of the pulse current on the intelligent system of the harmonic reducer. He expressed that the annual production capacity of 600,000 new industrial plants will be gradually handed over in 2019. It is not simply to reduce the cost of enterprises for customers, but should be based on large-scale production and manufacturing, to ensure the reliability of commodities with high requirements for quality, based on information management, intelligent system work, MES system software, soft operations, etc. Maintain the quality control and tracking of closed-loop control to assist the continuous upgrading and improvement of commodities.
