Abstract
A large converter construction that is trunnion-supported in a driven expansion bearing and a driven fixed bearing with a trunnion-receiving bushing and a trunnion-connected driving toothed wheel on either side, has torque-transmitting crowned rollers inserted between the bushing and the trunnion, at least on the expansion side. A force-locking connection between the trunnion and bushing is provided on the fixed bearing side. The fixed bearing assembly also comprising a bearing containing inner rings and outer rings with spherical running faces having a common center.
Claims11
A drive and bearing arrangement for a large converter construction with an expansion bearing assembly on one side, a fixed bearing assembly opposite the expansion bearing assembly and driving means for both the expansion bearing assembly and the fixed bearing assembly, characterized in that the expansion bearing assembly comprises
- a first bushing with recesses of semi-circular cross-section therein,
- an axially movable first trunnion supported in said first bushing and having recesses of semi-circular cross-section therein, the recesses in said first bushing and the recesses in said first trunnion complementing one another so as to form spaces of circular profile,
- a first driving toothed wheel in connection with said axially movable first trunnion, and
- torque-transmitting crowned rollers located within said spaces of circular profile;
- and further characterized in that the fixed bearing assembly comprises
- a second bushing,
- a second trunnion, part of which protrudes into and is force-locked to said second bushing,
- a second driving toothed wheel in connection with said second trunnion, and
- a bearing, containing inner rings and outer rings, provided between the bushing and the trunnion, said rings having spherical faces acting as mutual running faces, which running faces have a common center.
