Description
Foreliggende oppfinnelse vedrører en aksel-nav-forbindelse for marin propell med en på akselens sylindriske ende anbringbar hylse, på hvis koniske ytterflate ved kilevirkning er montert et med tilsvarende indre konisitet utformet propellnav. The present invention relates to a shaft-hub connection for a marine propeller with a sleeve that can be placed on the shaft's cylindrical end, on whose conical outer surface a wedge-shaped propeller hub designed with a corresponding internal taper is mounted.
Det er kjent å presse en propell med nav med konisk innerflate fast på en konisk akselende. Det er også kjent å benytte en hylse med en konisk ytterflate og en sylindrisk innerflate og å anordne denne hylsen på en sylindrisk akselende for fastpressing av propellen på den sylindriske akselenden. It is known to press a propeller with a hub with a conical inner surface onto a conical shaft end. It is also known to use a sleeve with a conical outer surface and a cylindrical inner surface and to arrange this sleeve on a cylindrical shaft end for pressing the propeller onto the cylindrical shaft end.
Presspasningen mellom propellen og akselenden oppnås ved å in-jisere olje under trykk i passasjer i navet samtidig som et spesielt verktoy brukes for å tvinge propellen inn på akselenden. Etter at propellen er blitt brakt i riktig stilling, stoppes oljeinjeksjonen og monteringsverktoyet fjernes. Det vil således oppstå en presspasning metall mot metall langs kontaktflatene mellom navet og hylsen og hylsen og akselen fordi oljen som blir benyttet for montering av propellen på akselen vil strbmme ut gjennom passasjene som ble benyttet for injiseringen. The press fit between the propeller and the shaft end is achieved by injecting oil under pressure into passages in the hub while a special tool is used to force the propeller onto the shaft end. After the propeller has been brought into the correct position, the oil injection is stopped and the mounting tool is removed. A metal-to-metal press fit will thus occur along the contact surfaces between the hub and the sleeve and the sleeve and the shaft because the oil that is used for mounting the propeller on the shaft will flow out through the passages that were used for the injection.
Når propellen skal fjernes fra akselenden, injiseres olje på nytt gjennom de nevnte passasjer, og dersom arrangementet er skikkelig konstruert, vil propellen skli mot den frie enden av akselen av seg selv. Ellers kan det benyttes et spesielt red-skap for å fjerne propellen fra akselen. When the propeller is to be removed from the shaft end, oil is re-injected through the passages mentioned, and if the arrangement is properly constructed, the propeller will slide towards the free end of the shaft by itself. Otherwise, a special tool can be used to remove the propeller from the shaft.
For mange anvendelser er de ovennevnte arrangementer ganske tilfredsstillende. Når store dreiemomenter skal overfores, har imidlertid en hylse og en akselende av ovennevnte type visse begrensninger, dvs. på grunn av den ikke-homogene fordeling av kreftene langs den koniske hylsen er det en risiko for at hylsen vil briste. Således er det viktig at et stort sett kon-stant overflatetrykk kan oppnås mellom den indre flate av hylsen og akselenden for at hoye dreiemomenter skal kunne overfores. For many applications the above arrangements are quite satisfactory. However, when large torques are to be transmitted, a sleeve and a shaft end of the above type have certain limitations, i.e. due to the non-homogeneous distribution of the forces along the conical sleeve, there is a risk that the sleeve will burst. Thus, it is important that a largely constant surface pressure can be achieved between the inner surface of the sleeve and the shaft end so that high torques can be transmitted.
Hovedformålet med oppfinnelsen er å tilveiebringe midler for eliminering av ovennevnte ulemper og for å gi sammenkoblinger av propellnav og akselender som tillater overforing av hoye dreiemomenter. The main purpose of the invention is to provide means for eliminating the above-mentioned disadvantages and for providing couplings of propeller hubs and shaft ends which allow the transmission of high torques.
Dette oppnås ifølge, oppfinnelsen ved en aksel-nav-forbindelse av den innledningsvis nevnte type som er karakterisert ved at hylsens sentrale boring er oppdelt i to eller flere avsnitt som med forskjellig boringsdiameter danner en eller flere ansatser mellom disse, at akselenden på tilsvarende måte er oppdelt i avsnitt med forskjellig ytre diameter og ansatser derimellom, at hylsens indre diameter i umontert tilstand er noe større enn akselendens tilsvarende ytre diameter, og at klaringen mellom hylsen og akselenden elimineres når navet drives på hylsen. This is achieved, according to the invention, by an axle-hub connection of the initially mentioned type which is characterized by the fact that the central bore of the sleeve is divided into two or more sections which, with different bore diameters, form one or more abutments between them, that the axle end is correspondingly divided into sections with different outer diameters and projections in between, that the inner diameter of the sleeve in the unassembled state is somewhat larger than the corresponding outer diameter of the shaft end, and that the clearance between the sleeve and the shaft end is eliminated when the hub is driven on the sleeve.
Hylsen kan forst plasseres på akselen, og så kan propellnavet presses inn på hylsen ved hjelp av et verktoy og olje injisert gjennom passasjer som forer til hylsen. Alternativt kan hylsen forst settes inn i navet, og deretter kan hylsen og navet plasseres på akselen. Propellnavet presses så inn på hylsen av et verktoy under samtidig oljeinjisering mellom propellnavet og hylsen. The sleeve can first be placed on the shaft, and then the propeller hub can be pressed onto the sleeve using a tool and oil injected through passages leading to the sleeve. Alternatively, the sleeve can first be inserted into the hub, and then the sleeve and hub can be placed on the axle. The propeller hub is then pressed onto the sleeve by a tool while simultaneously injecting oil between the propeller hub and the sleeve.
En fordel ved oppfinnelsen er at de koniske deler, dvs. propellnavet og hylsen, kan fremstilles av en og samme produsent, slik at det ikke vil være behov for korreksjoner eller justeringer når propellnavet monteres på akselen. Slike korreksjoner er ellers vanligvis nodvendige fordi propeller og aksler vanligvis ikke er fremstilt av samme produsent. An advantage of the invention is that the conical parts, i.e. the propeller hub and the sleeve, can be produced by one and the same manufacturer, so that there will be no need for corrections or adjustments when the propeller hub is mounted on the shaft. Such corrections are otherwise usually necessary because propellers and shafts are usually not produced by the same manufacturer.
Til tross for det faktum at meget nbyaktig verktoy er tilgjen-gelig, har de ovennevnte korreksjoner alltid vært nodvendige, selv i tilfelle hvor forskjellige produsenter er blitt gitt . identiske maler for forming av henholdsvis propellboringen og akselenden. Hvor koniske hylser med en og samme indre diameter i hele sin linje har vært brukt, har det oppstått problemer med kraftfordeling langs hylsen. Despite the fact that very recent tooling is available, the above corrections have always been necessary, even in cases where different manufacturers have been provided. identical templates for shaping the propeller bore and the shaft end, respectively. Where conical sleeves with the same inner diameter throughout their line have been used, problems have arisen with force distribution along the sleeve.
For bedre forståelse av oppfinnelsen skal det i det fblgende gis en beskrivelse av en spesiell utforelsesform av oppfinnelsen under henvisning til medfolgende tegning som viser et delvis snitt gjennom en kobling mellom et propellnav og en aksel, hvor forbedrede låsemidler ifolge oppfinnelsen er benyttet. For a better understanding of the invention, a description of a special embodiment of the invention shall be given in the following with reference to the accompanying drawing which shows a partial section through a coupling between a propeller hub and a shaft, where improved locking means according to the invention have been used.
På tegningen er det vist en akselende 10 som omfatter to sylindriske partier 11 og 12 av forskjellig diameter. En kant 13 vil derfor dannes, og i den viste utforelse er kanten 13 plassert stort sett midtveis langs en hylse 14 som har tilsvarende sylindriske partier. I umontert tilstand er diameterne av de indre omkretsflater 15 og 16 av hylsen 14 blitt storre enn diameterne av de sylindriske akselpartiene 11 og 12. Den ytre overflate av hylsen 14 er avsmalnende, og denne konisitet tilsvarer konisiteten av et propellnav 17. I navet 17 er det anordnet passasjer 18 og 19 for injeksjon av olje under montering og demontering av propellen. The drawing shows a shaft end 10 which comprises two cylindrical parts 11 and 12 of different diameters. An edge 13 will therefore be formed, and in the embodiment shown, the edge 13 is placed roughly midway along a sleeve 14 which has corresponding cylindrical parts. In the unassembled state, the diameters of the inner peripheral surfaces 15 and 16 of the sleeve 14 have become larger than the diameters of the cylindrical shaft parts 11 and 12. The outer surface of the sleeve 14 is tapered, and this taper corresponds to the taper of a propeller hub 17. In the hub 17 is it arranged passages 18 and 19 for injection of oil during assembly and disassembly of the propeller.
I montert tilstand er propellen låst til akselen ved hjelp av en hydraulisk mutter 21. When assembled, the propeller is locked to the shaft by means of a hydraulic nut 21.
Som nevnt ovenfor kan hylsen plasseres på akselen separat, og deretter kan propellen presses inn på hylsen ved hjelp av et verktoy og olje injisert i passasjene 18 og 19. Alternativt kan hylsen sammen med propellen plasseres på akselen. Propellnavet presses da inn på hylsen ved hjelp av et verktoy og oljeinjeksjon mellom propellnavet og hylsen. Klaringen mellom hylsen 14 og akselenden 10 vil forsvinne når hylsen vil kom-primeres når navet 17 monteres på akselen. På grunn av det faktum at innerflaten av hylsen omfatter minst to partier av forskjellig diameter, vil partiene med storre diameter være plassert suksessivt mot den divergerende ende av den utvendige koniske hylsen, idet tykkelsen av hylsen vil være stort sett jevn i hele hylsens lengde, slik at fordelingen av overflate-trykket mellom hylsen og akselen vil være stort sett jevn. Derfor vil det ikke oppstå problemer ved overforing av hoye dreiemomenter. Dette er hovedfordelen ved oppfinnelsen. As mentioned above, the sleeve can be placed on the shaft separately, and then the propeller can be pressed onto the sleeve using a tool and oil injected into the passages 18 and 19. Alternatively, the sleeve together with the propeller can be placed on the shaft. The propeller hub is then pressed onto the sleeve using a tool and oil injection between the propeller hub and the sleeve. The clearance between the sleeve 14 and the shaft end 10 will disappear when the sleeve will be compressed when the hub 17 is mounted on the shaft. Due to the fact that the inner surface of the sleeve comprises at least two portions of different diameters, the portions of larger diameter will be located successively towards the divergent end of the outer conical sleeve, the thickness of the sleeve being substantially uniform throughout the length of the sleeve, as that the distribution of the surface pressure between the sleeve and the shaft will be largely even. Therefore, no problems will arise when transferring high torques. This is the main advantage of the invention.
Som nevnt i det foregående demonteres propellen fra akselen As mentioned above, the propeller is dismantled from the shaft
ved ganske enkelt å fjerne den hydrauliske mutteren 21 og in-jisere olje i passasjene 18 og 19. Dette vil vanligvis være tilstrekkelig for fjerning av propellen fra akselen, men i enkelte tilfelle kan det være nodvendig å benytte et verktoy for fjerning av propellen. by simply removing the hydraulic nut 21 and injecting oil into the passages 18 and 19. This will usually be sufficient to remove the propeller from the shaft, but in some cases it may be necessary to use a tool to remove the propeller.
