How to design spherical roller bearing reasonably
Clicks:13976 Date:11-11
Experiments show that spherical roller bearing will appear in the form of destruction in the process of use:
(1) wear and tear: the wear is characterized by a certain amount of material removed from the contact surface uniformly, and the worn debris can be found on the surface of the lubricating oil and bearing raceway. Wear causes the gap between the bearing raceway of the bearing roller body to increase, the accuracy is reduced, and the vibration and noise become larger.
(2): contact fatigue and contact fatigue failure is caused by repeated use of detention material surface fatigue ultimate strength of contact stress, performance of surface or near the surface of the fatigue crack initiation and propagation, until the bearing groove material small fracture and stripping swing, leaving small pits.
