- 5 is a block diagram of another submarine propulsion system according to the invention.
- FIGS. 1 to 5 show different embodiments of submarine propulsion systems 1 according to the invention.
- All submarine propulsion systems 1 of FIGS. 1 to 5 have in common that they have a drive shaft 2, a drive propeller 3 coupled to the drive shaft 2 and a plurality of electrical machines 4, 5.
- At least one first electric machine 4 of a main drive for driving the drive shaft 2 and thus of the drive propeller 3 is designed for full-load operation of the submarine drive system and coupled or coupled on the drive side to the drive shaft 2.
- At least one second electric machine 5 of an auxiliary drive is designed for a partial load operation of the submarine drive system 1 and also coupled to the drive shaft 2 on the drive side or coupled, wherein in partial load operation of the submarine propulsion system 1, the submarine is typically operated in creeping and / or dive.
- the submarine propulsion system 1 it is therefore an idea of the submarine propulsion system 1 according to the invention to provide a plurality of electric machines 4, 5 for driving the drive shaft 2, namely a first electric machine 4 designed for full-load operation and a second electrical one designed for partial-load operation for crawl speed and / or dive travel Machine 5, which are dependent on the operating condition, that is, depending on whether a full load operation or partial load operation are desired, operated and for this purpose are coupled to the drive shaft 2 and decoupled from the same.
- the first electric machine 4 In full load operation, the first electric machine 4 is typically coupled to the drive shaft 2 and the second electric machine 5 is decoupled from the same.
- the second electric machine 5 In part-load operation, the second electric machine 5 is typically coupled to the drive shaft 2 and the first electric machine 4 is decoupled from the same.
- the first electric machine 4 of the submarine drive system 1 designed for full-load operation is indirectly or indirectly coupled to the drive shaft 2 via a first gear 6 on the drive side.
- the first gear 6 has gear planes 7, 8 of intermeshing gears, which provide at least one gear ratio
- the first transmission 6 is a transmission whose transmission stages are designed such that the first electric machine 4 can be operated at a significantly higher speed than desired for driving the drive propeller 3 and thus the drive shaft 2.
- the first electric machine 4 can be operated at a significantly higher speed than desired for driving the drive propeller 3 and thus the drive shaft 2.
- smaller, lighter and cheaper electrical machines for full load operation can be used, as is possible in known from practice submarine propulsion systems.
- the first transmission 6 comprises a clutch 1 1, which is preferably designed as a clutch or synchronizer clutch.
- the second electric machine 5 designed for partial load operation is supported or supported on the first gear 6 and coupled directly to the drive shaft 2 on the drive shaft 2, ie directly without any further gear ratio.
- Fig. 2 shows an embodiment in which the second, designed for full-load operation electric machine 5 while supported on the first gear 6 and is supported, but indirectly or indirectly via the first gear 6 is coupled to the drive shaft 2 on the drive side, namely in Fig. 2 via one of further gear levels 9, 10 formed, separate gear ratio of the first gear. 6
- the designed on the partial load operation, second electric machine 5 is mounted in accordance with the embodiments of FIGS. 1 and 2 on the first gear 6 and engages in the embodiment of FIG. 3 in accordance with the embodiment of FIG again indirectly via the first gear 6 on the drive side to the drive shaft 2 at.
- the second electric machine 5 does not engage, as in the embodiment of FIG. 2, via a separate ratio stage but rather via the gear stage of the first electric machine 4 formed by the gear levels 7 and 8 on the drive shaft 2. While the embodiment of Fig. 3 is particularly compact and simple, the embodiment of Fig. 2 has efficiency advantages.
- the respective submarine drive system 1 has a plurality of electrical machines, namely the first electric machine 4 for full-load operation and the second electric machine 5 for the part-load operation, the second electric machine 5 is supported or supported for the partial load operation on the first gear 6, which serves as a transmission gear at least for the first electric machine 4, which is designed for full-load operation.
- the first gear 6 also serve as a transmission gear for the second electric machine 5 designed for partial load operation.
- the submarine propulsion systems 1 of FIGS. 1, 2 and 3 furthermore have an axial bearing or thrust bearing 15 assigned to the drive shaft 2, an elastic compensating coupling 1 6 assigned to the drive shaft 2 and a shifting clutch 17 likewise associated with the drive shaft 2
- Thrust bearing 15 serves to receive axial forces acting on the drive shaft 2. Thrust forces are directed by the thrust bearing or thrust bearing 15 in the fuselage or in the foundation of the submarine. Moments are transmitted via the elastic compensating coupling 1 6 on the drive propeller 3.
- the drive propeller 3 can be decoupled from the drive shaft 2 via the clutch 17.
- Submarine propulsion systems 1 according to a second variant of the invention, Figs. 4 and 5, wherein the embodiments of Figs. 4 and 5 of the embodiments of Figs. 1 to 3 differ primarily in that in the embodiments of Figs. 4 and 5 the second, designed for partial load electrical machine 5 is not together with the designed for full load operation, the first electric machine 4 and the first gear 6 on the fuselage or foundation 12 of the submarine attacks or supported, but rather independent of the first electric machine 4 and the first gear 6 is supported on the foundation 12 of the submarine.
- FIG. 4 shows an embodiment in which the second electric machine 5 is coupled directly or directly, that is to say without a further transmission stage, to the drive shaft 2 on the drive side and as such is supported on the foundation 12 of the submarine via elastic sound damping elements 14.
- the second electric machine 5 designed for partial load operation is not coupled directly but indirectly via a separate second transmission gear 19 to the drive shaft 2 and via this second gear 19 and between the second gear Gear 19 and the base 12 of the submarine arranged, elastic vibration damper 14 supported on the foundation 12.
- Transmission gear for the first electric machine 4 serving first gear 6 are individually supported on the foundation 12, but without the need elastic damper 14, since in full load operation when using the first electric machine 4 a quiet operation of the submarine, as he particularly desirable at part load operation in creeping is of subordinate importance.
- a further difference of the embodiments of Figs. 4 and 5 of the embodiments of Figs. 1 to 3 is that in the embodiment of Figs. 4 and 5, the elastic compensating coupling 1 6 not as in the embodiment of Figs. 1 and 3 between the output the first gear 6 and the thrust bearing or thrust bearing 15 is connected, but rather between the thrust bearing or thrust bearing 15 of the drive shaft 2 and the second, designed for partial load electrical machine 5 or the second transmission 19th
- a low-noise operation of the submarine propulsion system 1 is only in partial load operation, especially at creep, important, so then in the embodiments of FIGS. 4 and 5, the elastic compensating coupling 1 6 exclusively for the independent of the first electric machine 4 and the first gear 6 supported on the foundation 12 of the submarine second electric machine 5 is important.
- a soundproof covering 18 is still arranged in order to ensure even quieter operation of the submarine propulsion system.
- the thrust bearing or thrust bearing 15 is integrated in the first gear 6, which serves as a transmission gear for the designed for full-load operation, first electric machine 4. This can then be realized further space advantages.
- the required drive power is provided by the first electric machine 4 in full load operation.
- the speed of the first electric machine 4 is higher than the required propeller speed to save size, weight and cost, which is why the first gear 6 comes with one or more gear ratios used.
- the first electric machine 4 can be switched on and off via the optional shift or synchronous clutch 1 1.
- torque is transmitted to the drive propeller 3 via the elastic compensation coupling 16, a thrust force acting on the drive shaft during operation is transmitted to the fuselage or foundation 12 via the thrust bearing 15.
- the required drive power is provided by the second electric machine 5.
- Submarines usually require only a small part of the power during slow and dive travel.
- the second electric machine 5, which is specially designed for partial load operation, is typically powered by batteries. In terms of range, the efficiency is therefore of particular importance for the partial load operation.
- the smaller, second electric machine 5 is in partial load operation at creep and dive in the range of its design performance and thus has an optimized efficiency, which causes a higher range.
- the second electric machine 5 is advantageously attached to the first gear 6 and connected in Fig. 1 directly to the drive shaft 2.
- the drive is optionally by the first electric machine 4 or the second electric machine 5, depending on power requirements.
- the first electric machine 4 can be decoupled via the clutch 11, which is particularly advantageous with regard to the efficiency.
- the second electric machine 5 is supported independently of the first electric machine 4 on the foundation 12. Since the first electric machine 4 is used only in less noise-sensitive operating states, the elastic mounting on the first electric machine 4 can then be dispensed with. In order to be particularly quiet during slow and dive trip, the second electric machine 5 is advantageously elastically supported on the foundation 12.
- the elastic coupling 1 6 is only necessary between the second electric machine 5 and the propeller shaft 2, the same can be advantageously made significantly smaller.
- the thrust bearing or pressure bearing 16 is preferably integrated in the housing of the first transmission 6.
- the first gear 6 may advantageously be a tunnel gear.
- a fast-rotating design is used for the second electric machine 5 in order to save weight, installation space and costs even in the area of the second electric machine 5.
- the second transmission 19 is used in Fig. 5.
- the second electric machine 5 and the second gear 12 are advantageously aligned rigidly to each other and stored together elastically on the foundation 12.
- controller can automatically control clutches and electric machines in order to automatically use the first electric machine 4 in full-load operation and automatically use the second electric machine 5 as a drive source in partial-load operation.
- Operating parameters can also be monitored via the control in order to automatically produce the desired operating configuration and drive power either in full load operation via the first electric machine 4 of the main drive or in partial load operation for crawl speed and / or dive travel via the second electric machine 5 of FIG To provide additional drive.
