| 摘要 |
The invention relates to a planetary gearbox, in particular for a wind turbine, comprising a gear housing (1), a central sun gear (2) which is held in the gear housing (1) and rotatable about a central gear axis (X) and carries an outer toothing (2a), a ring gear (3) which is arranged concentrically to the central gear axis (X) in the gear housing (1) and has an inner toothing (3a), a planet carrier (4) which is mounted in the gear housing (1) and rotatable about the central gear axis (X) , and a plurality of planetary gears (9) which are mounted on the planet carrier (4) via planetary gear bearings (10) and rotatable about planet carrier axes (11) and have outer toothings (4a) which mesh with the inner toothing (3a) of the ring gear (3) and the outer toothing (2a) of the sun gear (2), wherein the planet carrier (4) is supported against the gear housing (1) via at least one segmented radial sliding bearing (8) which comprises a plurality of radial sliding bearing segments (8a, 8b, 8c) arranged at a distance from each other in a circumferential direction, wherein the radial sliding bearing segments (8a, 8b, 8c) are radially positioned outside of the planet carrier axes (11), so that the planet carrier (4) is supported by the radial sliding bearings (8a, 8b, 8c) at positions which are located radially outside of the planet carrier axes (11). |
