Abstract (en)
[origin: WO2021005186A1] The invention relates to a gearbox 1, e.g. for a duo-electric machine drive train, comprising a sump (160) into which at least one first gear (77) dips. A first gear (77) and a second gear (49, 50, 79) form a gear stage (55) adjacent to a multi-chamber system (200). The second gear (49, 50, 79) acts as a centrifugal lubrication film separator gear in order to separate oil from the surface of the gear (49, 50, 79) using centrifugal force and deliver said oil to the multi-chamber system (200). The multi-chamber system (200) acts as a flow path that continuously delivers a lubricant (162) and through which lubricant can pass by means of a delay means (180, 180', 180") into the sump (160). Such a system can also be part of a bearing bracket. In such a multi-chamber system (200), lubricant (162) sprayed by the second gear (49, 50, 79) is caught in one chamber (202, 204) of the multi-chamber system (200), stored in another chamber (204, 206), and recirculated into the sump (160) only via a delay means (180, 180', 180").
