Abstract (en)

[origin: WO2015067429A1] The invention relates to a transmission, in particular for a wind turbine, comprising a transmission housing (3, 4, 13) and at least one planetary stage. The planetary stage has at least one planet carrier (2) with at least one first channel (14) for conducting lubricant, and the planet carrier (2) is rotatably mounted in the transmission housing (3) by means of at least one bearing (1), which can be a rotary bearing in particular. At least one part of the transmission housing (3), at least one part of the planet carrier (2), and at least one part of the bearing (1) form a cavity (16). According to the invention, the first channel (14) is designed such that lubricant can exit the first channel (14) into the cavity (16) so that at least one part of the lubricant reaches the bearing (1).
