Comparison of planetary bearing load-sharing characteristics in wind turbine gearboxes [PDF]
Wind Energy Science, 2018 In this paper, the planetary load-sharing behavior and fatigue life of different wind turbine gearboxes when subjected to rotor moments are examined. Two planetary bearing designs are compared – one design using cylindrical roller bearings with clearance

Influence of the Number of Rollers on a Tapered Roller Bearing [PDF]
Journal of Mechanics Engineering and Automation, 2014 In roller bearings, the outer ring is usually fixed and the inner ring has the rolling motion. Concerning TRB (tapered roller bearings), this motion generates forces that are transmitted to the outer ring by the tapered rollers. Thus, contact stresses occur and the number of rollers plays a major role with respect to the load distribution.
