Abstract:
1. A shaft-misalignment-measuring device comprising: a plurality of first gap-measuring sensors that are mounted at a plurality of points in a circumferential direction of a first bearing where a first shaft of a first body of revolution is mounted; a plurality of second gap-measuring sensors that are mounted at a plurality of points in a circumferential direction of a second bearing where a second shaft of a second body of revolution is mounted; and a shaft-misalignment operating section which obtains misalignment of center of said first shaft from center of said first bearing from dimensions between a plurality of said points in a circumferential direction of said first bearing and said first shaft that are measured by said first gap-measuring sensors; obtains misalignment of center of said second shaft from center of said second bearing from dimensions between a plurality of said points in a circumferential direction of said second bearing and said second shaft that are measured by said second gap-measuring sensors; and calculates a part of shaft-misalignment amount of said first and second shafts based on misalignment of centers of said first and second shafts.
