Abstract

A planetary gearbox includes a gearbox housing, a sunwheel rotatable in the housing about a central gearbox axis and having outer teeth, a ringwheel arranged concentrically to the central gearbox axis within the housing and having inner teeth, a planet gear carrier rotatable in the gearbox housing about the central gearbox axis, and a plurality of planet gears mounted on the planet gear carrier for rotation about corresponding planetary gear pins and having outer teeth meshing with the inner teeth on the ringwheel and the outer teeth of the sunwheel. At least one segmented radial sliding bearing supports the planet gear carrier on the gearbox housing and includes a plurality of circumferentially spaced-apart radial sliding bearing segments positioned radially outside the planetary gear pins so that the planet gear carrier is supported by the radial sliding bearing at a position located radially outside the planetary gear pins.
