Description

technical field

[0001] The invention relates to a bearing transmission unit as a drive and support assembly of a drying drum or suction roll of a paper or board machine, having a bearing for supporting the journal of the drying drum or suction roll, a gear rigidly connected to the journal and the drive pinion that drives this gear. Bearings, gears and drive pinions are housed together in a common housing. The invention also relates to a dryer component with a bearing drive unit according to the invention. Background technique

[0002] In the dryer sections of paper and board machines, the paper web after the press section is guided along a tortuous path through individual drying cylinders, which are pressurized from the inside with steam. The wet paper web, which wraps as much as possible on the drying cylinder, is dried during this time, so that condensation forms in the interior of the drying cylinder, wherein the condensation water is drained from the cylinder through h...
