COMBINED FRICTION BEARING IN A PLANETARY DRIVE
The invention relates to a planetary gearbox comprising at least one sun gear ( 17, 18 ) and at least one planet carrier ( 5 ) arranged coaxially with and rotatably in relation to said gear, a combination of a bearing sleeve ( 40 ) and a slide ring ( 41 ) that is separate therefrom being located between the sun gear ( 17, 18 ) and the planet carrier ( 5 ). The invention also relates to a gearbox combination of a differential of the spur-gear differential type, in the form of which the planetary gearbox is configured, and an additional planetary stage, the spur-gear differential and the planetary stage preferably having a common planet carrier ( 5 ) composed of multiple planet sub-carriers ( 6, 7, 8 ) that are non-rotatably combined.
