Identifiion of loading conditions resulting in roller slippage in gearbox bearings of large wind turbines

Too low value of the pre‐load will not provide sufficient loading capacity, but too high values will increase contact stress and frictional moment in the bearing. Proper value of the pre‐load will be crucial for bearings mounted in WT''s gearboxes, because of varying loads due to turbulent wind and gusts and emergency shut‐downs.

Turbine components: bearings - Windpower Engineering & …

16/6/2015· In main-shaft bearings, modular wind-turbine designs commonly use spherical-roller bearings (SRB) units that are more than 1m in diameter. Designers often select single SRB designs, one supported by a single main bearing and two torque arms that carry gearbox reaction loads. At least two factors contribute to early failures in main-shaft bearings.
