Abstract
The invention relates to a planet gear having a planet carrier rotatable around an axis of rotation, comprising at least one planet wheel arranged on the planet carrier, a sun wheel and a ring gear, wherein the planet wheel is arranged in a movable manner at least radially with respect to the axis of rotation of the planet carrier. To minimize the backlash of a planet gear of this type, it is further provided that the ring gear is formed in two pieces on a plane perpendicular to the axis of rotation of the planet carrier, wherein the two halves of the ring gears can be rotated against each other and thereby effect a radial shift of the planet wheel in the direction towards the sun wheel in order to reduce backlash.
