AI Technical Summary
Technical Problem
The open-hole design of existing tapered roller bearings allows external impurities to enter and lubricating oil to overflow, affecting the bearing's lubrication performance and service life.
Method used
The design employs a logarithmic busbar raceway, combined with an oil injection channel, oil outlet, and leak-proof components to ensure a stable supply of lubricating oil. It also filters impurities through a filter cartridge to prevent lubricating oil leakage and the entry of external impurities.
Benefits of technology
This achieves stable lubrication of the bearing, prevents lubricating oil leakage and impurities from entering, and extends the bearing's service life and operational stability.
