The crew of farmers and workers who took the wheel down from the windmill examine now the problem that forced us to replace rotor’s shaft and pinion gear.
The issue lies squarely on the flawed connection of shaft, lubricant case and pinion gear. By welding three separate parts, relatively weak joints had been created: eventually, the fast rotation of the wheel warped the shaft.
Understanding the causes of this failure is essential to optimize windmill technology, which has been recently introduced in the village. Increased reliance on wind energy depends on its adaptation to the village context, and broader local know-how about construction, maintenance and repair.
