<p>The planetary gear has an internally toothed gear (3) and a sun wheel (4) with their axes aligning with a rotational axis (L), and a number of planet wheels (5) rotatable in housings in a carrier (2) and meshing with the internally toothed gear and sun wheel. All the gearwheels have helical toothing. One meshing phase of at least one of the planet wheels with regard to the internally toothed gear and the sun wheel differs from the meshing phases of the remaining planet wheels with regard to the internally toothed gear and the sun wheel.</p>
