The angle gear box has a gear preliminary stage (1) that is provided a planetary gear (2). A drive-side gear (16) is rotatably connected to the crown wheel (15) of the crown wheel gear (3) and is driven by another planetary gear (4). The crown wheel gear and another planetary gear are housed in the gearbox housing (20). A pre-assembled unit (22) of another planetary gear is formed on the planet carrier (23) with planetary pinions (27). The ring gear (28) is positive-rotationally fixed in the gear box housing.
