The invention provides a ship shafting bearing load calculation method and system and a shafting alignment calculation system, and the calculation method comprises the steps: obtaining a theoretical equivalent jack load FJ based on a theoretical jacking curve graph of a jack and a jack load FJE corresponding to a headspace point, and calculating an equivalent jacking coefficient KN according to the jack load FJE, the theoretical equivalent jack load FJ and the jacking coefficient K. Obtaining an actually measured jacking curve graph and an actual equivalent jack load FJ'of the jack based on a jacking method; and calculating the bearing load at the ship shafting bearing according to the equivalent jacking coefficient KN and the actual equivalent jack load FJ '. According to the method, the bearing load value is calculated by obtaining the equivalent jack load, and the value serves as the bearing load at the ship shafting bearing. Compared with the prior art, the problem that the precision of the bearing load c
