Abstract
- Aiming at the abnormal wear problem on the inner ring of double spherical roller bearing, the bearing clearance, moller osculation, bearing roller profile modification and bearing span of the wind turbine bearings were studied and analyzed. Based on the effect of different bearing parameters on the contact pattern of the bearing roller, the useful methods were proposed to eliminate the edge contact problem. The three-dimensional model of the main shaft transmission system was built and analyzed with Romax software. The research results indicate that the bearing clearance has little effect on the bearing contact stress. By reducing the bearing roller tightness or modifying the miller profile, the odge stress concentration circumstance and the abnormal wear of the bearing raceways can be eliminated, while the contact stress of the roller can be increased. The bearing, span has major effect on the contact stress, the shorter bearing span is, the higher the miller contact stress is and the greater the edge contact stress is [ABSTRACT FROM AUTHOR]
