Abstract:
A multistage toothed gearing having a gear housing (1) and features:rotating about a common gearing axis (A) are the following: one input shaft (2) and one output shaft (3), a first gearwheel (5) which is fixedly connected to the input shaft (2), a fourth (10) and fifth (12) gearwheel having a mutual fixed connection, and a rotating carrier (4) mounted in the gear housing (1); rotating about at least one planetary axis (B) and running parallel to the common gearing axis (A) are the following: a second (6) and third (8) gearwheel with a mutual fixed connection and one planetary wheel (15) for each set of second and third gearwheels; the planetary axis (B) rotates about the common gearing axis (A); the gearwheel connections of said set of second (6) and third (8) gearwheels and the fourth (10) and fifth (12) gearwheels, respectively, are each rotationally mounted in the rotating carrier (4), a hollow wheel (16) is fixedly connected to the gear housing (1); intermeshing with one another are the following: the first gearwheel (5) and the second (6) gearwheel, the third gearwheel (8) and the fourth (10) gearwheel, the fifth gearwheel (12) and the planetary wheel (15) and the planetary wheel (15) and the hollow wheel (16); the planetary wheel (15) and the hollow wheel (16) are arranged in a direction of the common gearing axis (A) between the first (5) and second (6) gearwheels and the third (8) and fourth (10) gearwheels, to which end the connection between the second (6) and third (8) gearwheels passes through the planetary wheel (15) allocated for these gearwheels on its planetary axis (B).
