Title: EPICYCLIC GEARING WITH A HIGH TRANSMISSION RATIO
Abstract:
The invention relates to epicyclic gearing, comprising a planetary gear stage (1) having a ring gear (2), having a sun gear (4) which is mounted on a sun gear shaft (3) for conjoint rotation, and having a planetary gear set (5) arranged radially between the ring gear (2) and the sun gear (4), wherein the planetary gear set (5) comprises a plurality of planetary gears (6), which are rotatably mounted on a planet carrier (7) and are interlockingly or frictionally connected to the ring gear (2) and the sun gear (4), and the planet carrier (6) is connected, for conjoint rotation, to a first shaft (8) which is provided as an input or output shaft, characterized in that the planetary gear stage (1) is connected to a spur gear stage (9), wherein the spur gear stage (9) comprises a second shaft (10) which is provided as an output or input shaft and has a first spur gear (11) mounted thereon for conjoint rotation, the first spur gear (11) is interlockingly or frictionally connected to the ring gear (2) and is at least indirectly connected to a second spur gear (12), and the second spur gear (12) is mounted on the sun gear shaft (3) for conjoint rotation.
