Abstract

A device for lubricating a power gearbox having a variable orientation and a closed space has a lubricating unit that supplies lubricant to at least one element of the gearbox, which needs to be lubricated. A collecting reservoir collects lubricant from the closed space. A drain screw chamber, within the closed space, has a number of orifices disposed between different zones of the closed space and the drain screw chamber for passing lubricant there between. At least one rotary drain screw, which is produced in the form of an Archimedean screw, is disposed in the drain screw chamber to convey the lubricant from the drain screw chamber to the collecting reservoir. A drive unit drives the drain screw in rotation for conveying the lubricant. The orifices open respectively different zones of the closed space to the drain screw chamber such that the drain screw chamber can always collect lubricant from the different zones regardless of the orientation of the gearbox.
