| 摘要 |
The invention relates to an arrangement for protecting the bearings of two coaxially mounted rotors (1, 2) in an apparatus such as a mill, mixer or the like, in which the drive shafts (8, 9) of the rotors (1, 2) are passed to the rotors (1, 2) from the same side of the apparatus. The invention is based on adapting, close to the plate located in the rotor housing (14, 15, 16) of the apparatus on the bearing side, that is, the rotor housing bottom plate (14), a centrifugally acting scraper vane plate (18) that blows material landing on the bottom plate (14) radially outward and additionally adapting close to the scraper vane plate (18) a labyrinth seal (20) via which a vacuum-induced air flow is passed to the scraper vane plate (18). |
