ABSTRACT:
A planetary gear train having planetary gears (8) which are rotatably mounted on a planet carrier (18) and are in toothed contact with an internally toothed ring gear (14) and a sun gear (4). For a simplified, process-safe and inexpensive backlash of the planetary gears (8) without axial displacement of the sun gear (4), the ring gear (14) and the planetary gears (8) are conically designed so that planetary gear axles (16) are retained in the planetary gear carrier (18) at an inclined angle (a) and that the planetary gears (8) are axially movably disposed upon and coordinated with the planetary gear axles (16) and the position of the planetary gears (8) can be adjusted within the planetary train by adjusting mechanisms for adjusting a backlash.
