Abstract (en)
[origin: WO2018100259A1] Device for guiding the lubricating oil in a hollow shaft of a gearbox (1), comprising an oil recovery deflector (2) sitting at least partially over the end of the shaft and of its rolling bearings, which is connected to an introduction tube (3) engaged inside the end of the hollow shaft, characterized in that the deflector (2) has the following functional zones: – a zone (a) which is plugged in order to optimize the bearing filling volume, – a zone (b) which is cut out to collect lubricant coming from the bottom of the gearbox, – a zone (c) in which lubricant is raised back up by rotational drive, – a V-shaped opening (d) for collection of lubricant by scrapers and for orientating the flow towards the tube.
