Abstract
During wind turbines operation, yaw and pitch bearings suffer from sequential traction-compression stresses causing millions of micro movements per cycle between the gear teeth. This situation reduces the lubricant thickness between the teeth until metal contact appears causing excessive wear. The pitch gear lubrication at the zero degree position is carried out during unwind periods or programmed stops that cause important losses in electricity generation. Moreover, low efficiency of current lu...
