摘要：
The invention relates to a backlash-free planetary gear unit comprising a sun gear, an internal gear and at least one planet gear which is in mesh with said sun gear and said internal gear and which is arranged on a planet carrier such that it is rotatable about a planetary axis of rotation, wherein the toothed planet gear has a plane of division which is oriented perpendicular to the planetary axis of rotation and by means of which the planet gear is divided into a first planet subgear and a second planet subgear, wherein the first planet subgear is preloaded relative to the second planet subgear by a spring bar arranged in these two planet subgears substantially parallel to the planetary axis of rotation, and wherein a plurality of spring bars is arranged around the planetary axis of rotation.
