LCJS-001 - Precision Reducer (RV/Harmonic/Planetary) Performance Overview - Product Background
Overview:
Industrial robot technology is one of the key technologies for intelligent manufacturing, and it is considered a priority for future development in advanced manufacturing in the U.S., Germany's Industry 4.0, and China's Made in China 2025. The competition in industrial robots has escalated to the level of national industrial strategy, with the manufacturing and testing of critical components like precision reducers being monopolized abroad. To ensure high rigidity and positioning accuracy in industrial robots, RV reducers must feature short transmission chains, small inspection sizes, high power, and high precision, demanding rigorous manufacturing and testing standards. Currently, domestic research on RV reducers tends to focus on theoretical model analysis, the effects of machining and assembly errors, clearances, gear mesh stiffness, and bearing stiffness on transmission accuracy. Considering these factors, the comprehensive performance testing system for precision reducers (RV/harmonic/planetary) is widely used in the field of industrial robots. Ensuring product performance and quality during product development and factory inspections is crucial for the comprehensive performance testing of precision reducers (RV/harmonic/planetary), thus rigorous testing of their performance is particularly important. This system is based on the national standard GB/T 35089-2018 Test Methods for Precision Gear Transmission Devices for Robots and refers to other national standards and comprehensive performance tests for various reducers.
