A planetary gearset () has a sun gear () connected rotationally fixedly to an input shaft (), a carrier () that carries planetary gears () and is connected rotationally fixedly to an output shaft (), and a ring gear () fixedly connected to a housing () that encloses the planetary gearset (). To reduce the noise emission from the planetary gearset with as little structural complexity as possible without reducing its efficiency due to pressure rings that are guided and slide against the planetary gears and the carrier, the sun gear (), the planetary gears () and the ring gear () are provided with helical teeth and the input shaft () is at least indirectly supported on the housing (), in both axial directions, by way of a single roller bearing ().
