(57) Abstract Objective Interpolation facilities it is done in the propulsion shafting which reaches to the propeller shaft from the main engineOutput of the main engine receives restriction, with the capacity of the elastic coupling it is denseWith the marine propulsion shafting structure which is not offered. Constitution Vis-a-vis propeller shaft 7of a left and right pair and 7b, main engine 1In the propulsion shafting structure which through the reduction gear device, transmits outputPutting, propeller shaft 7of a left and right pair and 7b respectively individuallyTo dispose reduction gear device 3a and 3b, on the one hand propeller shaft 7aForming the input axis 4of a reduction gear device 3a in hollow tube, the main thingTo make the output axis 2 of the engine penetrate completely, in the output axis intermediate position elastic coupling 5Interpolation facilities doing a, to concatenate, the reduction gear device of other propeller shaft 7bThe input axis 4b of 3b in output axis 2 edge of main engine 1 elastic coupling 5Interpolation facilities doing b, the marine propulsion shafting structure which features that it concatenatesIt is structure.
