PXI-6230 On the afternoon of January 23, Giant Wheel Intelligence asked questions from netizens on the Shenzhen Stock Exchange interactive platform, confirming that the company’s RV reducer has entered the stage of industrialization.

On January 11, when users asked the secretary of the board on the interactive platform about the progress of the company’s RV reducer business, the reply of Giant Wheel Intelligence was still that the product had obtained the CR product certification, and revealed the cooperation with other companies, did not mention the industrialization stage, and inferred that the giant wheel intelligent RV reducer entered the industrialization stage should occur in mid-January.

Reducer is the core parts of the robot, accounting for 30% of the cost price of the robot, but the reducer market is basically monopolized by overseas brand suppliers, reducer localization is one of the important topics of domestic replacement of the core parts of the robot, the main application of the reducer on the robot has precision planetary reducer, harmonic reducer, RV reducer and other three types.

PXI-6230 RV reducer is composed of cycloidal pin wheel and planetary bracket, with small size, strong impact resistance, large torque, high positioning accuracy, occupies an important position in the field of high-precision transmission, so it is widely used in a variety of robot joint parts that need precise control, such as legs, waist and elbow.

In 2023, with the popularity of humanoid robots, the reducer was pushed to the forefront again. According to the published information of the Tesla Optimus humanoid robot, the Optimus humanoid robot will be equipped with about 40 actuators, of which the integration of the “motor + reducer” is the main power combination of the large joint.

PXI-6230 However, due to the large size of the RV reducer, high bearing capacity and stiffness and other characteristics, it is usually only applied to the humanoid robot base, arm, shoulder and other heavy load parts, a humanoid robot only needs about 2 RV reducer to meet the design requirements, and for the lighter load of the end joint may use harmonic reducer.

Industrial robots also use a large number of RV reducer, taking a typical six-axis industrial robot as an example, usually need to use 6 reducer, “2 RV reducer +4 harmonic reducer” combination is the most common.

PXI-6230 In addition to robots, RV reducers are also used in sophisticated manufacturing and inspection equipment. For example, in semiconductor manufacturing equipment, oxidation furnaces, coating development equipment, lithography machines, etchers, ion implanters and other equipment require extremely high accuracy and stability, and the high precision and high load capacity of RV reducers make them ideal for these applications.

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

PXI-6230 As early as 2013, Giant intelligent began to layout robot key parts research and development, especially the robot RV reducer research and development, after ten years of unremitting efforts, finally in May 2023, the good news, giant intelligent has broken through foreign technology monopoly, to solve the mass production of key technologies, to overcome the robot key parts “jam neck” problem.

On May 9, 2023, the “precision cycloidal pinwheel reducer /JLRV40E” produced and inspected by Julun Intelligence obtained the CR product certification issued by the National Robot Inspection and Evaluation Center, which is the second enterprise to obtain CR certification for RV reducer after Nbosk, and also the first CR certification for RV reducer for domestic enterprises. It fills the gap of China robot CR certification in this field.

PXI-6230 China Robot CR certification mark is jointly issued by the National Development and Reform Commission, General Administration of Quality Inspection, Ministry of Industry and Information Technology, Accreditation Administration, including the core parts of the robot, the robot body and the specific application of the robot standardized certification system, among which, RV reducer certification includes performance testing, durability test, allowable bending moment test and other links. Such as serial product certification needs to complete the factory site review and other procedures.

The first batch of domestic CR certification of another enterprise is Japan’s Nabotsk company under the Shanghai Nabotsk transmission equipment Co., LTD. Nabotsk is also an important supplier of the global robot transmission system, the market share of more than 60%, giant wheel intelligence and its certification, also shows that the domestic reducer products have completely replaced the quality of imported products.

After obtaining CR certification, also immediately harvest strategic large orders, it is understood that Wuhu Asclecleka Robot Technology Co., Ltd. to the giant wheel intelligent batch purchase 50000 sets of RV reducer, while with Guangdong Province industrial robot manufacturing enterprises to reach technical cooperation, customized research and development of different specifications of RV reducer, some new products have been put into the market.
