FIELD: metallurgy. ^ SUBSTANCE: invention concerns receiving of aluminium by electrolysis in cryolite - aluminous melts. Particularly it concerns anodic facility of aluminium electrolyser. Anodic facility contains anodes, anode lead, beam- manifold and screw jack containing of body, driving screw, worm gear, sliding nut bearing at globular rests through thrust blocks and screw. Inside of jack worm gear it is implemented chamber. Inside of chamber there is installed plunger pump for lubrication of frictionising bearing faces. Chamber through the system of filling channels is connected to annular lubrication groove. From the opposite to system of filling channels side in screw wheel it is located escape channel, communicating to annular oil groove. System of filling channels and escape channel are connected to annular oil groove in plane angularly 180°±45°. ^ EFFECT: reliability improvement, service life of screw jack increasing for vertical displacement of aluminium electrolyser anode and providing of oil dribble exception from jack. ^ 2 cl, 3 dwg |
