ASYMMETRIC TAPERED ROLLER BEARING FOR SUPPORTING A GEAR WHEEL ON A GEARBOX SHAFT

摘要

The invention relates to a bearing assembly for a gearbox for supporting a gear wheel (1) on a gearbox shaft (2), comprising a two-row asymmetric tapered roller bearing (4) in O arrangement, which has a first row of tapered rollers (4a), which is adjacent to the shaft end (3), and a second row of tapered rollers (4b), which is adjacent to the first row of tapered rollers (4a), wherein the two rows of tapered rollers (4a, 4b) are arranged between a common outer ring (5) arranged on the gear wheel (1) and a respective inner ring (6a, 6b) arranged on the gearbox shaft (2), wherein a first acute pressure angle (7a) on the first row of tapered rollers (4a) is not equal to a second acute pressure angle (7b) on the second row of tapered rollers (4b). According to the invention, the first pressure angle (7a) is at least 3° less than the second pressure angle (7b).
