Abstract

571,745. Vertical thrust bearings. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. May 5, 1944, No. 8508. Convention date, May 27, 1943. [Classes 12 (i) and 12 (iii)] A supporting disc 2 on a rotating shaft 1 rests on spring-supported bearing blocks 4 in an oilfilled space 8 and is formed with radial ducts 6 from which the oil is thrown centrifugally into an annular chamber 10 in the bearing housing 3 from which it can pass back to the space 8 through pipes 16, 15 and cooler 14. Oil escaping between the disc 2 and an annular projection 3<1> on the bearing housing is caught in a well 11 and returned through a pipe 13 to the space 8. The projection 3<1> may be formed with labyrinthine slots 12, a screen lying close to the inclined surface of the disc 2, or a bearing surface engaging the side of the disc 2 to limit the escape of oil upwardly to the well 11. The projection may be perforated to provide a direct connection from the labyrinthine slots to the well 11.
