China's own RV reducer has entered the mass production stage!

　　January 11, netizens on the interactive platform to ask the secretary about the company's RV reducer business progress, the wheel of intelligence is still the product has obtained CR product certification certificate, as well as revealed the cooperation with other companies, did not mention the industrialization stage, inferring that the wheel of intelligence RV reducer into the industrialization stage should occur in mid-January.

　　Reducer is the core components of the robot, accounting for the robot cost price of 30%, however, the reducer market is basically monopolized by overseas brand suppliers, the localization of the reducer is one of the core components of the robot local replacement of one of the important issues, the main application of the robot reducer has a precision planetary reducer, harmonic reducer, RV speed reducer and other three types.

　　RV reducer consists of cycloid pinwheel and planetary bracket, with the advantages of small size, strong impact resistance, high torque, high positioning accuracy, etc. It occupies an important position in the field of high-precision transmission, and is therefore widely used in various robot joint parts that require precision control, such as legs, waist and elbows.

　　In 2023, with the humanoid robot out of the circle of popularity, the speed reducer is once again pushed into the limelight. According to Tesla Optimus humanoid robot has been publicly available information, Optimus humanoid robot will be equipped with about 40 actuators, in which the integration of "motor + reducer" is the main power combination of large joints.

　　However, due to the RV reducer larger, higher capacity and stiffness and other characteristics, usually only be applied to the base of the humanoid robot, arm, shoulder and other heavy loads, a humanoid robot about only 2 RV reducer can meet the design requirements, and for the end of the lighter end of the load joints may use harmonic reducer.

　　Industrial robots also use a large number of RV gearboxes. A typical six-axis industrial robot, for example, usually requires the use of six gearboxes, with "two RV gearboxes + four harmonic gearboxes" being the most common combination.

　　In addition to robots, RV gearboxes are also used in precision manufacturing and testing equipment. For example, in the semiconductor manufacturing equipment, oxidation furnace, coating and developing equipment, photolithography, etching machine, ion implantation machine and other equipment for precision and stability requirements are very high, the high precision and high load capacity of the RV gear reducer makes it an ideal choice for these applications.

　　However, the domestic RV reducer research and development is not smooth, by the overseas technology blockade and the lack of high-precision CNC machine tools, etc., in 2022, the Japanese brand in the RV reducer market share of about 58%, seriously compressed China's robotics industry chain space, hindering the development of the robot industry.

　　Wheel Intelligence as early as 2013 began to layout the key components of the robot R & D, especially the robot RV reducer R & D, after ten years of unremitting efforts, and finally in May 2023, good news, wheel Intelligence has now broken through the monopoly of foreign technology, to solve the key technology of batch production, to overcome the key components of the robot "neck" problem. The key components of robots have overcome the "necklace" problem.

　　On May 9, 2023, "Precision Cycloid Reducer/JLRV40E" produced and sent for inspection by Julun Intelligence won the CR product certification issued by the National Robotics Testing and Evaluation Center, which is the second enterprise to get the CR certification for RV reducer after Nabisco, and is also the first CR certification for RV reducer in China, filling the gap of China's robot CR certification. This is the second enterprise to obtain CR certification for RV gearboxes after Nabisco, and the first CR certification for RV gearboxes for domestic enterprises, which fills the gap of CR certification for Chinese robots in this field.

　　China Robotics CR certification mark is issued jointly by the National Development and Reform Commission, General Administration of Quality Supervision, Inspection and Quarantine, the Ministry of Industry and Information Technology, the commission, including the robot core components, robot body and robot application-specific items such as standardization of the certification system, in which the RV gearbox certification, including performance testing, endurance testing, permissible bending moment test and other links, such as serialized product certification needs to be completed in the field to complete the review of the factory and other procedures.

　　Another of the first domestic enterprises to obtain CR certification is Japan's Nabtesco Corporation under the Shanghai Nabtesco Transmission Equipment Co., Ltd. Nabtesco is also an important supplier of global robotics drive systems, market share of more than 60%, Julun Intelligence with its certification, but also illustrates the quality of domestic speed reducer products have been able to completely replace the imported products.

　　Julun Intelligent RV reducer CR certification, but also immediately harvested a strategic order, it is understood that the Wuhu Metallica Robotics Technology Co., Ltd. to Julun Intelligent in batches of purchases of 50,000 sets of RV reducer, and Guangdong Province, industrial robotics manufacturing enterprises to reach technical cooperation, customized research and development of different specifications of the RV reducer, some of the new products have been put into the market.
