The key components of industrial robots for the industrialization of robots are mainly composed of three core components: speed reducer, servo motor and control system. The manufacturing costs of the three major components account for 39%, 28%, and 22% respectively, among which the key components are The manufacturing cost of the reducer accounts for nearly 40% of the total cost of the robot. For a long time, China’s robots have been subject to developed countries, mainly key components controlled by the United States, Germany, Japan, the Czech Republic, and other countries, leading to China’s high-end equipment manufacturing industry, the core components of the robot basically relies on imports.
As a core component of the robot, the reducer has always been the bottleneck restricting the development of industrial robots in China. According to the prediction of the national authoritative department, a universal robot needs to be equipped with 4 to 6 sets of high-precision reducers. According to the calculation of 4.5 sets of reducers for each configuration, the new demand for reducer for industrial robots in China will reach 23.6 in 2015~2018. Ten thousand, 296,000, 369,000 and 462,000 sets. In addition, for the industrial robots held in the domestic market, calculated according to the average service life of 8 to 10 years, the market demand for precision speed reducers in the future will exceed 1 million units, and the annual market sales will exceed 10 billion yuan.
Facing the high dependence of the modern equipment manufacturing industry on the robot industry in the global economy and the rapid development of the foreign robot industry, Yin Longzhang, chairman of Jiangsu Tailong Group, proposed the development of a robot reducer as early as the “Twelfth Five-Year Planâ€. Assumption. Tailong chose the State Key Laboratory of Mechanical Transmission of Chongqing University as a technical support unit with a strong R&D foundation and innovative capabilities in the field of mechanical transmission in China. Through the combination of production, teaching and research, we are committed to the development and research of intelligent robot speed reducers. Through more than four years of extensive exchanges and in-depth cooperation, we have adopted multi-faceted theoretical research and processes, technologies, materials and materials.
