Abstract

A friction torque analysis method for wind turbine main bearing with the type of three-row cylindrical roller under combined loads is established. Firstly, by using an equilibrium equation system of bearing load distribution based on roller slicing processing, the load distribution of roller slices is analyzed and calculated under the combined action of external radial load, axial load, and tilting moment. Then, based on the analysis of relative sliding motion between bearing parts, the calculation formulas of roller-raceway sliding friction, roller-raceway rolling friction, cage-outer ring sliding friction and seal ring-inner ring sliding friction are deduced, and the calculation formula of total friction torque of bearing is obtained. Finally, for a specific wind turbine main bearing, the effects of axial clearance, roller number, roller length-diameter ratio, cage mass and seal ring interference on friction torque are solved and analyzed. The results show that the friction torque of the wind turbine main bearing with three-row cylindrical rollers mainly comes from the axial rollers. Reasonable axial clearance, roller parameters, cage mass and seal ring interference are very beneficial to the anti-friction design of this bearing.
