Background Technology

[0002] In modern gearbox design, retaining rings have become a key technology for axial bearing fixation. Compared with other axial fixing technologies, retaining rings offer several advantages: First, high-speed electric drive systems (such as electric vehicle gearboxes with speeds exceeding 20,000 rpm) require more precise bearing positioning, and retaining rings can control axial movement within 0.05 mm. Second, with the trend towards integrated design, retaining rings save 60% of axial space compared to threaded lock nuts, making the gearbox structure more compact. Finally, the maintenance-free nature of retaining rings perfectly matches the need for lifetime lubrication, and with the continuous development of electric vehicles, the advantages of retaining rings in preload control will further promote their application.
