Title
(EN) METHOD AND DEVICE FOR EVALUATING SHAFTING ALIGNMENT OF SHIP
(FR) PROCÉDÉ ET DISPOSITIF POUR ÉVALUER L'ALIGNEMENT D'ARBRE DE TRANSMISSION DE NAVIRE
(JA) 船舶における軸系アライメントの評価方法および評価装置
Abstract
(EN)
An evaluation map showing the allowable ranges (A) of the crank deflection and bearing loads determined according to the inclinations of the crankshaft and the countershaft of an engine is prepared beforehand. When the engine is installed in a ship, the inclinations of the shafts within the allowable ranges can be easily known. While the ship is in service, its shafting alignment can be evaluated by merely measuring the inclinations of the crankshaft and the countershaft.
(FR)
La présente invention concerne une représentation d'évaluation qui représente les plages admissibles (A) de la déflexion de manivelle et des charges déterminées selon les inclinations du vilebrequin et de l'arbre intermédiaire d'un moteur qui est préparée préalablement. Lorsque le moteur est installé dans un navire, les inclinations des arbres au sein des plages admissibles peuvent être facilement connues. Lorsque le navire est en marche, son alignement d'arbre de transmission peut être évalué en mesurant simplement les inclinations du vilebrequin et de l'arbre intermédiaire.
(JA)
 予め、機関におけるクランク軸の傾きおよび中間軸の傾きに応じて求められたクランクデフおよび軸受荷重の許容範囲(A)を示す評価マップを作成し、機関の船体への据付け時に、許容範囲内に収まるような各軸の傾きを簡単に知り得るようにするとともに、就航船にあっては、そのクランク軸および中間軸の傾きを測定するだけで、その軸系アライメントを評価することができる。
