Embodiment Construction

[0028] figure 1 shows a planetary gear 1 with a ring gear 10, a sun gear 20, a sun gear shaft 21, a planet gear 30, a planet bearing 31, a planet carrier or planet carrier 40, a bearing shaft 50, a shaft nut 51, a main bearing unit 60, eg Intermediate element 61 which is a washer, cover 70 , driver 80 , anti-rotation mechanism 90 and hub nut 100 . The sun gear shaft 21 and / or the planet carrier 40 with the planet carrier journal 41 can move relative to the cover 70 . Furthermore, the sun gear 20 and the sun gear shaft 21 can move relative to each other.

[0029] hub nut 100 in figure 1 is installed between the anti-rotation mechanism 90 and the ring gear 10 . The hub nut 100 is arranged here in such a way that it fixes the main bearing unit 60 in the axial direction. The main bearing unit 60 serves to support the ring gear 10 on the support shaft 50 .

[0030] as from figure 2 As can be seen, the hub nut 100 has a body 101 . For fixing the main bearing unit 60 , the hu...

Abstract

Provided are a hub nut for a planetary transmission and a planetary transmission. A hub nut (100;110;120;130) for a planetary transmission (1;2;3;4) has a body (101;111;121;131) configured to secure against unscrewing and to seal the planetary transmission (1;2;3;4).

Description

technical field [0001] The invention relates to a hub nut for a planetary gear and a planetary gear. Background technique [0002] A planetary gear is known from DE 60 2005 005 448 T2. The sun gear on the sun gear shaft and the planet carrier with the planet gears are arranged in the ring gear here. [0003] Planetary gears are used, for example, as traction gears for larger and smaller drivers. For such planetary gears, however, there are generally a large number of different rotary seals with different geometries for fastening and sealing on the ring gear. As a result, the ring gear and possibly further parts of the planetary gear can be adapted in each case to the rotary seal used. [0004] Furthermore, additional stationary sealing elements such as O-rings or other elastic sealing means can be mounted on the ring gear on the main bearing. For this purpose, in most cases additional structural elements are required in the ring gear, for example grooves in the ring gear...
