AI Technical Summary
Existing spherical plain bearings suffer from severe wear on the contact surfaces of the inner and outer rings due to structural design defects, resulting in short service life and complex and costly manufacturing processes.
The inner and outer rings are designed with double-loop lubrication grooves and lubrication guide grooves on their inner walls, respectively. They are treated with phosphating and molybdenum disulfide coating, combined with arc-shaped contact surfaces and rounded chamfers, to simplify the processing and improve lubricity and wear resistance.
It improves the lubricity and load-bearing capacity of bearings, reduces stress concentration, extends service life, and facilitates disassembly and assembly, while reducing processing difficulty and cost.
