Abstract
A planetary gear includes a planet carrier, a sun wheel, a gear ring, and planet wheels meshing with the sun wheel and with the gear ring. Each planet wheel shaft of the planetary gear is arranged to rotatably support a respective planet wheel so that, in an unloaded situation, a geometric axis of rotation of the planet wheel is skewed (α) with respect to the axial direction (z) of the planetary gear. In a loaded situation, torque directed to the planet carrier causes twisting deformation in the planet carrier and thereby the skewedness of the geometric axis of rotation is at least partly eliminated by the twisting deformation. Thus, in the loaded situation, the direction of the geometric axis of rotation can be closer to the axial direction than in a planetary gear where there is no skewedness in an unloaded situation.
