the gearbox failures are due to bearing failures [Shuangwen, 2013]. A gearbox bearing exchange cost can be from 15 k€ for a simple up-tower replacement to even more than 1 M€ for a larger (+5 MW) gearbox exchange. Off-shore is considered more costly than on-shore. The wind power industry is however still young when machines over 2 MW

The decisive factor for the transmission of power in belt drives is the circumferential force (also called effective force), which results from the difference between the tight side force and the slack side force of the belt! At the pulley with the diameter d o driven by the belt this effectively circumferential force F c leads to a changed ...
