<P>PROBLEM TO BE SOLVED: To provide a bearing system having long lifetime even though it is suitable for an operation load at a wide range. <P>SOLUTION: The bearing system for a wind turbine rotor has a double-row tapered roller bearing 5 at an O-shaped arrangement. The double-row tapered roller bearing 5 at the O-shaped arrangement has an inner ring 7, a train of tapered rollers 9 in a peripheral direction supported on the inner ring 7, a floating inner rib 14, a drive device 26, and a detachable interlocking device 17-24. The floating inner rib 14 is axially moved at a predesignated position by the drive device 26 so as to abut on each large roller end 11 facing axially outward in order to apply a corresponding preload on each tapered roller 9, and is rigidly coupled to the inner ring 7 by means of the interlocking device 17-24. <P>COPYRIGHT: (C)2011,JPO&INPIT |
