Joints of robots: Count down those giant reducers that have become famous for so long.

The RV reducer, which is one of the core components of the robot transmission, has the highest cost in robot manufacturing and its importance is self-evident. The localization of precision reducers is imminent and is a big issue in the future robot development strategy. In this year's annual inventory, Xiao Bian will give you a breakdown of the famous robot reducer companies at home and abroad. Joints of robots: It is understood that the technical thresholds of reducers are very high. Some domestic companies have made major breakthroughs in the technical level, but the accuracy of domestic reducers is maintained, accuracy There are difficulties in research and development in terms of life and product life. Difficulties have resulted in poor consistency of domestic reducers and low reproducibility between products. Therefore, the domestic reducer is still not able to form a mass production. Currently, it can only rely on imports, which seriously restricts the demand for autonomous market. It can be seen that the localization of precision reducers is imminent and is a big issue in the future robot development strategy. The following Xiao Bian for everyone to look at the famous robot reducer enterprises at home and abroad.
Precision reducers for robots are crucial applications in the robot industry chain. For a long time, precision decelerator technology for robots has been controlled by the United States, Germany, Japan, the Czech Republic and other countries, resulting in the slow development of the robot industry in the high-end equipment manufacturing industry in China, and can only rely on imported RV reducer. So, who are the giants of reducers abroad? 1. Hamnaco Japan HDSI was established in 1970. It is the world's largest harmonic reducer manufacturer and a leader in overall motion control. Its Harmonic Drive combined harmonic reducer is lightweight and small Gear gaps, high torque capacity, and other characteristics are widely used in industrial robots, humanoid robots, semiconductor liquid crystal production equipment, photovoltaic equipment, optical instruments, precision machine tools and other cutting-edge fields. 2. Nabo Nabo was merged from Teijin Machinery Co., Ltd. and Naboco Co., Ltd. in 2003. It is the world's largest manufacturer of precision cycloidal pin wheel reducer, with a market share of 60%. Teijin Seiki Co., Ltd. and Nabok Co., Ltd. are manufacturers of motion control systems and components. Both companies control high market share and master high-end core technologies in their specific business areas and make them Japan and the world are ranked first. In May 2013, Shanghai Electric Motor Co., Ltd. announced that it will increase its shareholding in Nabo Drive, Shanghai Mechatronics will account for 51% of the joint venture, and Japan Nabtesco Co., Ltd. will occupy 49% of the equity. 3. Sumitomo Sumitomo Co., Ltd. is a construction machinery manufacturer owned by Sumitomo Group, one of the world's top 500 companies, and has a worldwide reputation. Sumitomo Heavy Industries launches reducers in the Chinese market are mainly hollow C series and RV-like T series, the main direction of attack is the system integration field. With the increasing emphasis on the Chinese market and the rise of domestic reducer manufacturers, Sumitomo Reducer's market in China is constantly being squeezed. 4, SPINEA Spinea company was established in 1994, is committed to high-precision bearing reducer R & D, production and sales of the world's fourth-ranked bearing reducer manufacturers. Spinea reducer has T series (including 60-140 TB mini series, 170-300 large series), E series, H series and B series. 5. Saijin In 2006, Singapore SERVODYMAMICS and South Korea SEJINIGB jointly invested in the construction of Suzhou Sai Jin Precision Equipment Co., Ltd. Sai Jin was first introduced into the Chinese mainland market by Suzhou Yongxin Automatic Control Co., Ltd. SEJINIGB can make the RV reducer model relatively small, like harmonics, had attacked some of the body companies for some time. However, the development of the market was not very satisfactory. In the past two years, the market movements were small and there were signs of gradually disappearing. The RV reducer, which is one of the core components of robot transmission, has the highest cost in robot manufacturing and its importance is self-evident. The “Research and Development of Made in China 2025” published in May 2015 also listed the research and development of the reducer, and proposed to break through the key components and system integration design and manufacturing of the robot body, reducer, servo motor, controller, sensor and driver, etc. Technical bottlenecks. However, in recent years, there are no mature manufacturing processes for RV reducers in the country that can be used for reference, and many companies are daunting. However, there are also some companies that have worked hard to achieve deeper research in the area of ​​reducer and have achieved certain results. 1. Shanghai Mechatronics Shanghai Mechatronics Co., Ltd. is a large-scale listed company that leads the rapid development of China's electromechanical equipment manufacturing enterprises and is the parent company of China's largest equipment manufacturing group. Shanghai Mechanical & Electrical Corporation was listed on the Shanghai Stock Exchange in 1992. The company's business involves seven fields: elevator manufacturing, refrigeration air-conditioning equipment manufacturing, and printing and packaging machinery manufacturing. In May 2011, Shanghai Mechatronic Co., Ltd. increased its capital by investing 51% in Nabo Drive and jointly cooperated with the robot project to develop a precision reducer. At present, the company's annual sales revenue is 11 billion yuan. 2. Development of Qinchuan Two major advantages of gear processing and precision manufacturing are important support for the development of Qinchuan into the field of industrial robot joint reducers. Qinchuan Development not only provides gear processing equipment, but also engages in gear processing, and its gear machining precision is at the leading level in China. In addition, Qinchuan's development of precision machining of boxes, shafts and other various parts is also very prominent. These are related to the company's origin of grinding machine, because the grinding machine has the highest precision in the machine tool. At present, Qinchuan has developed an automatic gear production line that can mass-produce parts for the robot joint reducer. 3. Zhejiang Hengfengtai Zhejiang Hengfengtai is a leading product of reducer and mixing equipment, and has extended its reach to large-scale electromechanical automatic control devices such as lifting equipment, aluminum industry equipment, high-efficiency sedimentation tank equipment, aluminum electrolyzer anode lifter, and busbar lifting frame.
