"National Harmonic Gear Reducer for Robots" National Standard issued and implemented

The General Administration of Quality Supervision, Inspection and Quarantine and the National Standardization Administration of the People's Republic of China were promulgated in the “National People's Republic of China Standards Announcement” No. 14 of 2014. The Harmonic Gear Reducer for Robots (GB/T 30819-2014) was published in 2014. 5 Released on the 6th and officially implemented on December 31, 2014.

The national standard of GB/T 30819-2014 "Harmonic Gear Reducer for Robots" was compiled by Suzhou Green Harmonic Drive Technology Co., Ltd., Jiangsu Reducer Product Quality Supervision and Inspection Center, Shanghai ABB Engineering Co., Ltd. and Beijing Technology and Business University. The standard basically covers the classification principle, technical requirements, performance indicators, test methods, inspection rules, packaging, transportation, storage, etc. of harmonic gear reducers for robots, and the product models, classifications, and dimensions of harmonic reducers. Technical specifications such as transmission efficiency, torsional stiffness, noise, temperature rise, and service life, as well as the corresponding test methods, test equipment, and inspection rules, are regulated in the main technical content for China's robotics industry, semiconductor manufacturing, optical instruments, medical Precise harmonic products in the fields of instruments, communications equipment, aviation, aerospace, machine tools, energy, etc. have positive guiding significance.

In 2013, China has become the largest robot market in the world, selling 37,000 robots that account for nearly one-fifth of global sales, and its sales volume has increased by 60% year-on-year. It will be the second and third largest robotic country in Japan and the United States. More than 10,000 units were opened. At the same time, the sales volume of domestic robots only accounts for about 5% of the domestic market share. The bottleneck that plagues the healthy development of the robot industry in China is that the core components cannot be self-sufficient. Harmonic decelerator is the core component of the robot to achieve the movement function, and is an indispensable component for the reliable and accurate operation of the light industrial robot and the manipulator. Compared with the general gear transmission, the harmonic decelerator has high movement accuracy and transmission ratio. Large, light weight, small size, large carrying capacity, high efficiency, easy to achieve zero backlash, and can work normally in confined spaces and media radiation conditions, etc., now about 90% of the harmonic reducer is used in Harmonic retarder has become an important basic component of modern industry in robot industry and precision positioning system.

Due to the fact that the technical indicators of domestic harmonic products have been lower than foreign countries for a long time, the harmonic reducers used in the current advanced manufacturing industries mainly in the robot industry in China are heavily dependent on imports. In recent years, Suzhou Green's Harmonic Drive Technology Co., Ltd. has gradually overcome the bottleneck of harmonic transmission technology, and possesses the technology and capability of large-scale production. The products quickly occupy the market, breaking the monopoly of foreign countries. Therefore, with the introduction of the "National Harmonic Gear Reducer for Robots" national standard, it is of great significance to promote the progress of harmonic transmission technology and product upgrading in China, and promote the healthy development of the entire robot industry in China.
