Research and Analysis on National Standards for Electric Multiple Units Gear Oils(GB/T 40701-2021)
High-speed EMUs have more complex and demanding friction and wear issues.With the rapid development of high-speed railways in China,especially the fast growth of high-speed EMU gearbox technology,higher requirements have been put forward for the performance of gearbox lubricants.In order to solve the problem of the lack of unified stand-ards for EMU gearbox lubricants at home and abroad,and to provide lubricants with reliable performance for EMU gearbox-es,ensuring the safe operation of high-speed EMUs,China has formulated the national standardGB/T40701-2021 Elec-tric Multiple Units Gear Oils,which officially came into effect on May1,2022.The paper conducts research and analysis on the specific technical requirements of the GB/T40701-2021.The formulation and implementation of GB/T40701-2021 is of great significance to achieve comprehensive independent development of high-speed EMU technology in China.
