| 摘要 |
The invention concernes a planetary gearbox (1) with helical-cut teeth, in particular a vehicle gearbox, with sun-wheel teeth disposed round the drive shaft (2), several planet pinions (4) mounted in a pinion cage (6), and a ring gear (7) surrounding the planet pinions (4) and held by a carrier (8). Thrust collars (17, 18, 21, 22) are fitted between the drive shaft (2) and the planet pinions (4) and between the planet pinions (4) and the ring gear (7) in order to absorb axial forces. Between the sun-wheel teeth and the pinion cage (6) is a device (72, 74, 80) designed to hold one of the two thrust collars (17, 18), the device absorbing the axial force in the helical teeth which is directed towards the pinion cage (6) and binding it to the drive shaft (2).
