Problems solved by technology

[0009] This joining technique requires relatively large bolts due to the large forces to be absorbed, making it difficult to miniaturize the overall design
Furthermore, bolts do not ensure exact positioning of the different parts relative to each other; additional reference elements such as alignment pins are required
Furthermore, fastening with bolts makes it difficult to use ring gear segments made of plastic in gearboxes, since the load-carrying capacity of the threaded holes with small diameters is not sufficient to allow the necessary fastening force

Embodiment Construction

[0044] figure 1 It is a perspective view of a planetary gear train 1 with a plurality of uncoupled ring segments 2 according to the present invention just before assembly. Each of all segments 2 (only shown here) includes a planetary gear set that includes a sun gear, a plurality of planetary gears carried by a planet carrier, and a ring gear with internal teeth. 2 is arranged between the adaptor plate 13 of the motor 11 and the adaptor plate 13 of the gear head 12 and the output ends thereof follow one another in the axial direction. The present invention does not teach any design restrictions related to the design of the gear head 12 and its adapter plate 13. Therefore, the adapter plate 13 and the gear head 12 can be manufactured or constructed as a single piece or separately manufactured or constructed.

[0045] on figure 2 In the assembled state, the adjacent ring segment 2 and the outer ring segment 2 of the corresponding adapter plate 13 with the motor 11 and the gear he...

Abstract

The invention relates to a multi-stage planetary gear train (1), comprising several annular segments (2) arranged one behind the other in the axial direction between the adapter plates (13) of the motor (11) and of the gear head (12), each annular segment having a planetary gear set comprising a sun gear, several planet gears carried by a planet carrier, and a ring gear having inner teeth, wherein adjacent annular segments (2) are coupled to each other and the outer segments (2) are coupled to the respective adapter plates (13). The invention is characterized in that the annular segments (2) and the corresponding adapter plates (13) in the region of the adjacent end faces (3) thereof form a coupling area (4) each, and the segments (3) each comprise at least one engaging element (5) on one end face (3) thereof and at least one complementary receiving element (6) on the opposite end face (3) thereof, wherein the engaging element (5) of a segment (3) engage in the receiving element (6) of an adjacent segment (3) or of an adapter plate (13) in a form-fit or force-closed manner in the assembled state.

Description

Technical field [0001] The present invention relates to a multi-stage planetary gear train / planetary gear train, which at least includes a plurality of rings arranged one behind the other in the axial direction between the adapter plate of the motor and the adapter plate of the gear head Segments, each ring segment has a planetary gear set including a sun gear, a plurality of planet gears carried by a planet carrier, and a ring gear with internal teeth, wherein adjacent ring segments are coupled to each other and the outer segment is coupled to the corresponding rotation Connect the board. Background technique [0002] Generally, a planetary gear train has a special configuration of a compact gear train with shafts arranged coaxially with each other. [0003] The basic design includes a gear set that includes a sun gear, a plurality of planet gears carried by a planet carrier, and a ring gear (ring gear) with internal teeth from the inside to the outside. [0004] However, not only...
