DRIVELINE BETWEEN A ROTOR AND A GENERATOR OF A WIND TURBINE

摘要

A driveline configured to connect a wind turbine rotor and a wind turbine generator has a planetary gear unit having a planet carrier rotatably supported relative to a housing part by at least one rolling-element bearing. The rolling-element bearing includes at least one inner ring and least one outer ring, and a plurality of rolling elements are disposed between the at least one inner ring and the at least one outer ring. The rolling element bearing further includes a spacer element disposed between adjacent pairs of the plurality of rolling elements, the spacer elements each having first and second running surfaces for guiding first and second ones of the plurality of rolling elements, and, apart from the spacer elements, a region between the bearing rings includes no cage elements.
