Further, it is necessary to perform piping between the cooler f and the constant speed drive device d, and piping between the cooling water pumps g, g' and the cooler f each time.

When this happens, it is difficult to control the constant speed, and its performance may become unstable.

次に、本考案の一実施例を第１図について説明
する。 Next, an embodiment of the present invention will be described with reference to FIG.

した定周波発電装置９に連結する。 A propeller 3 is connected to the downstream side of the marine main engine 1 via a reduction/reversing gear or a reversing gear 2, and a constant speed drive device 4 and an alternating current generator 5 are connected to the crankshaft end of the downstream side of the main engine 1. A cooling device is sequentially connected to the case and provided on one base plate 6, and is directly driven by the heat exchange type cooler 7 attached to the constant speed drive device 4 and the shaft on the opposite side of the alternator 5. A water pump 8 and the like are also provided on the same base plate 6 and connected to a constant frequency power generation device 9 that integrates a constant speed drive device 4 and an alternating current generator 5.

時に、交流発電機５の反対側軸により駆動される
冷却水ポンプ８も一定速度で回転し、安定した冷
却作用が行なえる。 With this structure, even if the main marine engine 1 changes its rotational speed for propulsion, the alternator 5 driven by the constant speed drive device 4 rotates at a constant speed and generates electricity at a constant frequency. At the same time, the cooling water pump 8 driven by the shaft on the opposite side of the alternator 5 also rotates at a constant speed, so that a stable cooling effect can be performed.
また、定速度駆動装置４は、伝達トルクが少い
（交流発電機５の負荷が軽い）ときは、つれ回り
現象により回転速度を制御しにくくなるが、交流
発電機５の反対側に付いている冷却水ポンプ８が
負荷の役割をするので、交流発電機５の負荷が軽
い（電力が使用されない）ときでも、定速度制御
がしやすくなる。 Furthermore, when the transmitted torque is small (the load on the alternator 5 is light), it becomes difficult to control the rotational speed due to the drag phenomenon. Since the cooling water pump 8 acting as a load, constant speed control becomes easy even when the load on the alternator 5 is light (no power is used).

も済む。 Further, a constant speed drive device 4 is mounted on one base plate 6.
By combining the AC generator 5 and the AC generator 5 into a single case, the unit can be made smaller, and the heat exchange type cooler 7 and cooling water pump 8 attached to the constant speed drive device 4 can be mounted on the base plate 6. This makes the installation work easier, and the above-mentioned unitized system can be stored in the dead space on the bottom side of the main marine engine 1, so there is no need to take up extra space to install the power generator. It's done too.

できる。 Further, when the rotation transmission function of the constant speed drive device 4 is turned off, there is no need to cool the constant speed drive device 4, but when the device 4 is turned off accordingly,
Since the alternating current generator 5 and the cooling water pump 8 are stopped, unnecessary power for driving the pump 8 can be saved.
なお、前記実施例では冷却水ポンプ８を直結駆

定速度制御性能を発揮する。 Further, in the embodiment described above, the main engine 1 and the constant frequency power generation device 9 are arranged in series, but the same effect can be obtained if they are arranged in parallel and driven by a V-belt/V-pulley. According to the present invention, as described above, the constant speed drive device and the alternator, which are driven and connected from the outboard side crankshaft end of the marine main engine, are coupled together on the same base plate into a case, and the alternating current is generated. The cooling water pump is driven by the shaft on the opposite side of the machine, and the cooling water pump and the heat exchange type cooler of the constant speed drive device are also piped on the same base plate, so the equipment can be made into a unit, making it more compact. It is easy to install, requires little installation space, and saves the trouble of piping work. Furthermore, since the cooling pump is also controlled at a constant speed, the cooling action is performed with stable rotation. Furthermore, since the cooling water pump serves as a load, the constant speed drive device exhibits stable constant speed control performance even when the alternator is under a light load.
