AI Technical Summary
Existing harmonic reducers suffer from stress concentration and severe wear issues with their flexible bearings under load, especially under heavy loads, which makes the flexible bearings prone to annular fractures, a problem that is difficult to solve effectively with current technology.
Design a flexible bearing with an annular protrusion structure on the outer ring. The protrusion cooperates with the balls to disperse stress and reduce friction. Furthermore, by setting protrusions and grooves on the outer circumferential surface, stress is dispersed, lubrication is improved, and stress concentration is avoided.
It effectively reduces stress concentration on the outer circumference of flexible bearings, improves bearing life, enhances friction and meshing accuracy between the flexible wheel and the flexible bearing, and prevents fracture failure.
