The flexible bearing of harmonic reducer is a kind of bearing of harmonic reducer. It is a kind of bearing used outside the harmonic generator, which can realize the speed change requirement of large transmission ratio. Because of its special overall structure, it is installed in time is different from other types of bearings.
Assembly method of flexible bearing of harmonic reducer
1. Arc fill ball groove method
This method is actually that when the ball filling angle is greater than 195°, a circular arc groove that is larger than the diameter of the steel ball is opened in the distance from the inner and outer ring ribs to the bottom diameter of the groove. The steel balls are respectively filled into the channels. The arc ball-filling groove method has low installation efficiency, high production cost, and poor quality control, because if the ball-filling groove is deep, the ferrule will be scrapped; if it is shallow, the steel balls cannot be filled. Improper grooving will greatly reduce high-speed performance and limit axial play.
