Abstract

Planetary gearing, in particular multistage planetary gearing, is disclosed. The planetary gearing includes at least one drive shaft, an output shaft, a sun wheel, a ring gear, planet wheels assigned to the planetary gear train, a gear casing, in particular a multipart gear casing, a planetary gear train, in particular the second planetary gear train, comprising a planet wheel arm immovably arranged in a casing. The construction of such a planetary gearing is simplified compared to the prior art, thereby saving costs. This is achieved in that the planet wheel arm is integrally formed with a casing.
