Reducer, servo motor and controller are considered to be the three core parts of robot, and also the main bottleneck restricting the development of China’s robot industry. Overall, in the total cost of industrial robots, the proportion of core parts is close to 70%, among which the reducer occupies the largest proportion, 32%;The remaining servo motor and controller accounted for 22% and 12%, respectively.
Reducer is monopolized by foreign manufacturers
Focus on the reducer, which transfers power to the servo motor and adjusts speed and torque for more precise control of the robot.At present, the largest reducer manufacturer in the world is Japanese Nabotsk Precision Machinery Co., Ltd., which is a professional manufacturer of precision cycloid reducer for robot in a dominant position in the world, and its core product is precision reducer RV series.
Large technology gap
From the point of view of specific technology, reducer belongs to pure mechanical precision parts, materials, heat treatment technology and high-precision machining machine tools are indispensable, the core difficulty lies in the huge supporting industrial system behind.At present, our reducer research started late, technology lag behind Japan, heavily dependent on imports.
In addition, compared with foreign products, domestic enterprises currently produce harmonic reducer transmission accuracy, torque stiffness, accuracy and so on with foreign enterprises still have a gap.
Domestic companies are struggling to catch up
However, it is worth noting that although there is still a gap between the current technology and foreign countries, domestic enterprises are constantly seeking breakthroughs.After years of accumulation and technology precipitation, domestic enterprises have gradually gained international market recognition, product competitiveness and sales continued to improve.
Yooheart Company achieves RV reducer independent research and development production
Anhui Yunhua Intelligent Equipment Co., Ltd. established the relevant research and development team, actively research reducer, the company invested more than 40 million capital, the introduction of foreign advanced automation equipment, through years of exploration, successfully developed the own brand reducer – Yooheart RV reducer. Yooheart RV reducer on the technical requirements are very strict. But in the RV manufacturing technology, Yooheart reducer can control the error between 0.04mm. Yooheart reducer in production will pass through layers of checks, after the end of production by professional machine measurement accuracy, to ensure that the error is within a controllable range will be put into production.
