Description

Foreliggende oppfinnelse angår en anordning for fremdrift av skip og båter, omfattende en propell montert med horisontal aksel på en søyle som rager ned fra fartøyets skrog, hvor søylen omslutter en aksel for overføring av drivkraft fra en f remdri ftsmotor anordnet inne i fartøyet til propellens aksel. The present invention relates to a device for the propulsion of ships and boats, comprising a propeller mounted with a horizontal shaft on a column projecting down from the vessel's hull, where the column encloses a shaft for transferring driving force from a propulsion engine arranged inside the vessel to the shaft of the propeller .

For å oppnå styring av fartøyet er det tidligere kjent f remdri ftsanordninger av ovenfor omtalte type, f.eks. som inboard-outboard-anordninger og som såkalte, az imuth-thrustere, hvor propellen med tilhørende aksel og tilhørende søyle svinges om en vertikal akse. Disse tidligere kjente anordninger passer imidlertid dårlig for fartøyer beregnet for høyere hastig-heter, bl.a. på bakgrunn av de krav som stilles til vekt, virkningsgrad og kompleksitet. In order to achieve steering of the vessel, propulsion devices of the type mentioned above are previously known, e.g. as inboard-outboard devices and as so-called, azimuth thrusters, where the propeller with associated shaft and associated column is swung about a vertical axis. However, these previously known devices are not suitable for vessels designed for higher speeds, i.a. on the basis of the requirements for weight, efficiency and complexity.

For å fremskaffe et f remdr i ftssystem tilpasset disse krav er detIn order to provide a forward-looking system adapted to these requirements, it is

i henhold til oppfinnelsen foreslått en fremdri ftsanordning av den innledningsvis nevnte art, hvor det særegne består i at propellen er anordnet trekkende og ikke-svingbar i forhold til søylen og fartøyskroget og at søylen er utstyrt med midler for styring. Ytterligere trekk ved oppfinnelsen vil fremgå av kravene og av den etterfølgende beskrivelse. in accordance with the invention, a propulsion device of the type mentioned at the outset is proposed, where the distinctive feature is that the propeller is arranged to pull and cannot be pivoted in relation to the column and the vessel's hull and that the column is equipped with means for steering. Further features of the invention will appear from the claims and from the following description.

Oppfinnelsen skal beskrives nærmere under henvisning tilThe invention shall be described in more detail with reference to

vedføyde tegning, hvorattached drawing, where

Fig. 1 viser et sideriss av en f remdr i ftsa nordning i henhold til foreliggende oppfinnelse, Fig. 2 er et hor isonta 1sni11 gjennom søylen i fig. 1, etter linjen H-E i fig- 1 . Fig. 3 viser to diagrammer for trykkforskjellen på de to sider av søylen, med styrefinnen i nøytral henhv utsvinget stilling. Fig. 1 shows a side view of a f remdr in ftsa northing according to the present invention, Fig. 2 is a ho isonta 1sni11 through the column in fig. 1, following the line H-E in fig-1. Fig. 3 shows two diagrams for the pressure difference on the two sides of the column, with the control fin in a neutral or deflected position.

I fig. 1 betegner 1 bunnen i et hurtiggående fartøy, utstyrt med en f remdri ftsanordning i henhold til foreliggende oppfinnelse. Fremdri ftsanordningen omfatter et øvre vinkelgear montert i et gearhus 2 og forbundet med en ikke vist motor gjennom en aksel 3 og med et nedre vinkelgear i et gearhus 4 gjennom en aksel 5 som strekker seg gjennom en søyle 6. Det nedre vinkelgear er igjen forbundet med en propell 7, som kan være en i og for seg kjent vripropell. In fig. 1 denotes the bottom of a fast-moving vessel, equipped with a propulsion device according to the present invention. The propulsion device comprises an upper bevel gear mounted in a gear housing 2 and connected to a motor not shown through a shaft 3 and with a lower bevel gear in a gear housing 4 through a shaft 5 extending through a column 6. The lower bevel gear is again connected to a propeller 7, which can be a rotary propeller known per se.

Propellen 7 er anordnet trekkende i forhold til søylen 6, og propellen 7, det nedre gearhus 4 og søylen 6 er anordnet ikke-sv ingbart under fartøyet. The propeller 7 is arranged pulling in relation to the column 6, and the propeller 7, the lower gear housing 4 and the column 6 are arranged non-swingable under the vessel.

For styring av fartøyet er det på søylen anordnet midler for styring, nemlig en finne 8 anordnet i søylens, bakkant for svingninc om en vertikal aksel 9. Som det fremgår av hor isonta1sni11et gjennom søylen, se fig. 2, er finnen utformet som en del av søy1etverrsnittet, som i seg selv - i denne utføre1sesform - er "dråpeformet". Det ligger innenfor oppfinnelsens ramme å anordne styrefinnen på søylens forkant, eller eventuelt på både forkant og bakkant. Eventuelt kan finnen være delt i høyderetningen, f.eks. ved at søylen og en nedre finnedel strekker seg nedenfor det nedre gearhus 4. For steering the vessel, means for steering are arranged on the column, namely a fin 8 arranged in the column's trailing edge for turning about a vertical shaft 9. As can be seen from the horizontal section through the column, see fig. 2, the fin is designed as part of the needle cross-section, which in itself - in this embodiment - is "drop-shaped". It is within the scope of the invention to arrange the guide fin on the front edge of the column, or possibly on both the front edge and rear edge. Optionally, the fin can be divided in the height direction, e.g. in that the column and a lower fin part extend below the lower gear housing 4.

Effekten av en fremdrifts- og styreanordning i overensstemmelse med foreliggende oppfinnelse er anskueliggjort i fig. 3, The effect of a propulsion and control device in accordance with the present invention is illustrated in fig. 3,

hvor fig. 3A viser trykkforløpet på de to sider av søylen når styrefinnen 8 er i nøytra 1sti 11 ing , dvs med null utslag, og det fremgår at trykket er likt på de to sider av søylen. where fig. 3A shows the pressure progression on the two sides of the column when the control fin 8 is in the neutral position, i.e. with zero deflection, and it appears that the pressure is equal on the two sides of the column.

Fig. 3B viser også trykkforløpet på de to sider av søylen, denne gang med et lite utslag på finnen, og det fremgår at det er en trykkforskjell over hele søylen inkl. styrefinnen, til tross for at styrefinnen bare utgjør en liten del av søylens overflate. Fig. 3B also shows the pressure progression on the two sides of the column, this time with a small projection on the fin, and it is clear that there is a pressure difference over the entire column including the guide fin, despite the fact that the guide fin only makes up a small part of the column's surface .
