The reducer is an important part of the movable joint of industrial robots. The precision reducers used by industrial robots are mainly harmonic and RV reducers. The former is used at the ends of actuators such as wrists, hands and forearms due to its small size and low load, while the latter has larger volume and mass and strong stability. , larger loads, usually used on bases, shoulders and arms. The A1~A3 joints of a six-axis robot generally use RV, and the end execution joints A4 and A5 mainly use harmonic reducers. Mobile robot wheels can use precision planetary reducers. Reducers account for a large proportion of industrial robot production costs, and prices have dropped significantly after local mass production. The cost of precision reducers accounts for 36% of the total cost of industrial robots. According to Green's harmonic prospectus, from 2017 to 2019, its harmonic reducer production increased by 29%, and the average price dropped from 1,923 CNY to 1,632 CNY, a decrease of 15%. Subsequent costs are expected to be further reduced as production increases to achieve greater results. Widespread popularity.
The downstream industrial robot industry is developing rapidly, and the reducer market is gradually opening up.
High-precision transmission fields such as industrial robots and high-end CNC machine tools downstream of reducers are developing rapidly. There is a large gap in the overall supply of high-precision transmission parts represented by precision harmonic reducer products. The demand for products in the high-precision transmission field is increasing day by day, and the needs of downstream equipment manufacturers have not yet been met. Qianzhan Industry Research Institute predicts that China's CNC machine tool market will reach 572.8 billion yuan in 2024, and industrial robot sales are expected to continue to expand.
Global: The industrial robot market has entered a period of stable growth. According to IFR data, the annual installation volume of global industrial robots has shown an increasing trend from 2016 to 2021. Since 2014, the global industrial robot stock has maintained a high growth rate of more than 10% for a long time. In 2021, the global industrial robot stock has reached 34.77 million units. The demand for downstream industries of precision transmission devices, including precision reducers and mechatronics products, continues to expand. Innovation institutions and enterprises in the global robot industry continue to explore technology research and development and scenario development, and continue to expand their applications in automobile manufacturing, electronic manufacturing, warehousing and transportation, medical rehabilitation, emergency rescue and other fields, promoting the continued vigorous development of the robot industry. According to data from IFR and the China Electronics Society, the global robot market will exceed US$42 billion in 2021, of which the industrial robot market will reach US$17.5 billion, service robots will reach US$17.2 billion, and special robots will reach US$8.2 billion. The China Institute of Electronics predicts that the global robot market will exceed US$65 billion by 2024.
