Planetary gear stage with plain bearings as planet bearings and the use of a planetary gear stage |
摘要 |
The present invention provides a planetary gear stage (2) for a gearbox (1). The planetary gear stage (2) comprises a ring gear (8), a sun gear (9) and a planet carrier (4) for driving at least three planet shafts (6) each onto which at least one planet gear (5) having a radial contact surface (18) and an axial contact surface (20) is rotatably mounted by means of a plain bearing arrangement (7). The plain bearing arrangement (7) comprises two bushings (12) fixedly connected to the planet shaft (6), each fixed bushing (12) being L-shaped in cross-section and having a radial contact surface (13) and an axial contact surface (14). The fixed L-shaped bushings (12) are mounted to form a cross-sectional U-shape and are locked in axial direction at both outer sides by an abutment (15, 16, 24). At least part of the planet gear (5) is located within the U-shape formed by the fixed L-shaped bushings (12). The plain bearing arrangement (7) furthermore comprises a radial sliding support (17) in between the radial contact surface (13) of the fixed L-shaped bushings (12) and the radial contact surface (18) of the planet gear (5) and an axial sliding support (19) in between the axial contact surface (14) of the fixed L-shaped bushings (12) and the axial contact surface (20) of the planet gears (5). |
