Title:
減速逆転機
Document Type and Number:
Japanese Patent JP7359419
Kind Code:
B2
Abstract:
To provide a speed reduction and reverse gear 18 that transmits power of at least either of an engine 16 and a power generation motor 30 mounted on a ship 1 to a propeller 5 through a forward reverse mechanism 25, in which the speed reduction reverse gear 18 can be downsized as a whole.SOLUTION: The speed reduction and reverse gear 18 according to the present invention comprises a change-over mechanism 37 that can selectively connect the power generation motor 30 to an upstream side 24a and a downstream side 24b in power transmission from the engine 16 in the forward reverse mechanism 25. The change-over mechanism 37 is interposed between the power generation motor 30 and the forward reverse mechanism 25, so that the forward reverse mechanism 25 is interposed between the engine 16 and the change-over mechanism 37, which can prevent large torque from the engine 16 from being directly transmitted to the change-over mechanism 37. This eliminates the necessity for the change-over mechanism 37 to have large capacities, so that the change-over mechanism 37 and in turn the speed reduction reverse gear 18 can be downsized.SELECTED DRAWING: Figure 2
