との間に所要の隙間Ａに相当する軸受ギャップが残る。Next, the setting of the bearing gap will be described. The clearance (bearing gap) between the guide collar 1 and the pad 2 is A, and the clearance between the pad 2 and the spherical pivot 3a is B,
When the clearance between the spherical pivot 3a and the fixed cotter 3b is C, the clearance between the fixed cotter 3b and the driven cotter 3c is D, and the clearance between the driven cotter 3b and the bearing support 3d is E, the clearances A to E are all 0. Nut 3 so that
While the e is loosened, the driving cotter 3c is pushed down and tightened until the nut 3e contacts the upper surface of the cotter holder 3f. After that, the nut 3e is rotated by a rotation angle such that the bearing gap between the guide collar 1 and the pad 2 matches the predetermined gap A.
Is rotated to pull up the driving cotter 3c so that the gap D between the fixed cotter 3b and the driving cotter 3c becomes a predetermined gap A. When the water turbine generator rotates, the guide collar 1 comes into contact with the pad 2 and pushes the spherical pivot 3a and the fixed cotter 3b, so the gap D between the fixed cotter 3b and the driven cotter 3c disappears, and the guide collar 1 and the pad 2
And a bearing gap corresponding to the required clearance A remains.
