Abstract:
A propulsion system for a ship, comprising:a front and a rear propelling engines (M1, M2) coupled via a gear system (6) to a ship output (7), a front input shaft (9) of the gear system, having a first axis of rotation (1) and allocated to the front propelling engine (M1), a rear input shaft (10) having a second axis of rotation (2) and allocated to the rear propelling engine (M2), and a gear output (11) having a third axis of rotation (3) and is allocated to the ship output shaft (7), wherein the ship output shaft (7) extends below the rear propelling engine (M2), the second axis of rotation (2) is disposed vertically above the first axis of rotation (1) and the first axis of rotation (1) is disposed vertically above the third axis of rotation (3), and the third axis of rotation (3) disposed vertically below the first axis of rotation (1) and the second axis of rotation (2), and wherein the gear system (6) has an input gear (14), mounted for rotation by the rear input shaft (10) and permanently meshed with a first intermediate gear (Z2) coaxial with the first axis of rotation (1) and an output gear (13), mounted for rotation by the gear output shaft (11) and meshed with a second intermediate gear (Z1) mounted rotating about the first axis of rotation (1) so as to maximize the vertical axial distance between the rear input shaft (10) and the gear output shaft (11).
