PURPOSE:To provide possibility of checking the position of an unbalanced weight while a flywheel is in rotation, by sensing and calculating the number of revolutions of an adjusting shaft for the position of unbalanced weight. CONSTITUTION:Inside a flywheel casing 31, an unbalanced weight 32 is supported by a radially stretching screw shaft 33, which is coupled with weight position adjusting shafts 37A, 37B through a bevel gear 34. These adjusting shafts 37A, 37B are coupled with a table through clutches 38A, 38B, respectively, and equipped with rotation sensing discs 52, 53 for the rotation of respective shafts, and photo-electric tachometers 50, 51 are mounted facing said rotation sensing discs 52, 53. These rotation sensing discs 52, 53 and photo-electric tachometers 50, 51 provide possibility of checking the position of the weight 32 fitted on the above- mentioned screw shaft 33. |
