Title:
DYNAMO-ELECTRICAL MACHINE WITH SEGMENTED STATOR STRUCTURE AND/OR ROTOR STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2014/086633
Kind Code:
A3
Abstract:
The invention relates to a dynamo-electrical machine (1) with a stator (4) and a rotor (5), which is rotatably arranged relative to the stator (4) about an axis of rotation (R). The stator (4) and/or the rotor (5) has a plurality of segments (4a, 4b) arranged one after another in the rotational direction (S) of the rotor (5). The segments (4a, 4b) have a flange (9a, 9b) at the side ends (13a, 13b) thereof in the rotational direction for connection to segments (4a, 4b) arranged adjoining one another in the rotational direction (S), and the flanges (9a, 9b) have at least one hole (10a, 10b) in the rotational direction (S). Flanges (9a, 9b) facing one another at the side ends (13a, 13b) in the rotational direction of segments (4a, 4b) arranged adjoining one another are connected to one another with a screw connection (6) passing through a hole (10a, 10b). To connect the flanges (9a, 9b) facing one another, a sleeve (8) having an external thread (8a) is arranged in the hole (10a, 10b) of at least one of the flanges (9a, 9b) facing one another at the side ends (13a, 13b) in the rotational direction. The hole (10b) of at least one of the flanges (9a, 9b) facing one another at the side ends (13a, 13b) in the rotational direction has an internal thread (11b), the internal thread (11b) of the hole (10b) being screwed into the sleeve (8). The sleeve (8) creates a spacing between the flanges (9a, 9b) facing one another. A screw (12) passes through the holes (10a, 10b) of the flanges (9a, 9b) facing one another at the side ends (13a, 13b) in the rotational direction, and through the sleeve (8).
