OPENTECHNICAL PUBLICATION OT-2026-000000877 Planetary transmission, in particular for a motor vehicle Published: 2026-09-15T19:03:31.840277Z Permanent URL: https://opentechnical.org/p/OT-2026-000000877 Categories: Industrial Motion & Power Transmission > Rotary Motion ------------------------------------------------------------------------ ABSTRACT A planetary transmission has a collecting groove for a lubricant and a planetary gear set having a planetary support rotatable around a planetary gear set axis of rotation in relation to a housing of the planetary transmission, planetary gears rotatably mounted on the planetary support, and a ring gear meshing with the planetary gears. The transmission has a disc coupling having an inner disc support connected to the collecting groove in a rotationally fixed manner, an outer disc support connected to the housing of the planetary transmission in a rotationally fixed manner, and a set of friction discs. The inner disc support is connected to the ring gear in a rotationally fixed manner. The ring gear and/or a cylinder portion connected to the ring gear in a rotationally fixed manner has a first lubricant channel running radially with respect to the planetary gear set axis of rotation. ------------------------------------------------------------------------ OpenTechnical publication OT-2026-000000877 Published 2026-09-15T19:03:31.840277Z https://opentechnical.org/p/OT-2026-000000877
