TAPERED ROLLER BEARING AND WIND TURBINE

The invention relates to a tapered roller bearing comprising an inner ring (1), an outer ring (2) and two rows of tapered rollers (3), which are arranged in an O-shaped arrangement between the inner ring (1) and the outer ring (2), wherein the inner ring (1) extends in an axial direction (X) over a greater length than the outer ring (2), and wherein a gap between the inner ring (1) and outer ring(2) on at least one side of the tapered roller bearing is sealed by a sealing assembly. According to the invention, the sealing assembly comprises a main seal (4) rotationally fixed onto the inner ring (1), as well as a seal race ring (5) rotationally fixed onto the outer ring (2), wherein the seal race ring (5) forms a seal raceway (6) for the main seal (4). 本发明涉及一种圆锥滚子轴承，其具有内圈(1)，外圈(2)以及两行在内圈(1)与外圈(2)之间以O形排布布置的圆锥滚子(3)，其中，内圈(1)沿着轴向(X)延伸经过比外圈(2)更大的长度，并且其中，内圈(1)与外圈(2)之间的间隙在圆锥滚子轴承的至少一侧处通过密封装置密封。根据本发明，密封装置包含旋转固定地连接在内圈(1)上的主密封件(4)以及旋转固定地连接在外圈(2)上的密封滚圈(5)，其中，密封滚圈(5)构成用于主密封件(4)的密封作用面(6)。
