1. wind turbine (100) with power train (300), described power train comprises:

  • Gear-box (302), it comprises gear box casing, at least one gear stage (252) and rotatably is connected in the interior output shaft (540) of described housing that described at least one gear stage (252) is applied to end thrust (525) on the described output shaft (540) at the run duration of described wind turbine;

    Generator (304), it comprises generator housing and input shaft (540), the described input shaft of described generator is connected on the described output shaft of described gear-box, described generator also comprises stator (506) and rotor (508), described stator is connected on the described generator housing, described rotor is connected on the described input shaft, makes described rotor radially inwardly locate from described stator;

    Shared at least one bearing (546) between the input shaft of the output shaft of described gear-box and described generator, at least a portion of the described end thrust of described at least one loading ability of bearing (525);

    Wherein, described generator (304) by deflection so that opposite end thrust (515) is applied on the described input shaft (540), so that reduce described bearing thrust by described at least one bearing (546) carrying.
