Description
Oppfinnelsen angår et drivledd for overføring av dreiebevegelse mellom en drivenhet og en propellaksel med en propell for fremdrift av en båt, idet drivleddet omfatter et fleksibelt ledd som er omsluttet av et hus og er innrettet til å oppta skyvekrefter fra propellen under drift. The invention relates to a drive link for the transmission of rotational movement between a drive unit and a propeller shaft with a propeller for propelling a boat, the drive link comprising a flexible link which is enclosed by a housing and is designed to absorb thrust forces from the propeller during operation.
Videre angår oppfinnelsen en anvendelse av drivleddet. Furthermore, the invention relates to an application of the drive link.
Det er tidligere kjent drivledd i forskjellige utførelser, for anvendelse som drivledd i forhjulsdrevne biler. Det dreier seg her om såkalte jevnhastighetsledd. Poenget med "jevn hastighet" er at det tradisjonelle kardangledd med et mellomakselkryss gir en ujevn hastighet som står i forhold til avviksvinkelen mellom den inngående og den utgående del av leddet. I et jevnhastighetsledd er dette problem eliminert. I en forhjulsdrevet bil er det en absolutt nødvendighet at man oppnår jevn hastighet, fordi man ellers ville få en vibrasjon i hele bilen når bilen fjærer eller svinger. There are previously known drive links in various designs, for use as drive links in front-wheel drive cars. This concerns so-called constant speed links. The point of "even speed" is that the traditional cardan joint with an intermediate shaft junction gives an uneven speed that is proportional to the angle of deviation between the input and the output part of the joint. In a constant velocity link, this problem is eliminated. In a front-wheel drive car, it is an absolute necessity that you achieve a steady speed, because otherwise you would get a vibration in the whole car when the car springs or turns.
De kjente jevnhastighetsledd er som nevnt konstruert for å benyttes i biler. Disse ledd kan normalt ikke utsettes for store skyvekrefter mer enn én vei. Dette er ikke noen vesentlig svakhet på det nevnte anvendelsesområde, da behovet for å benytte denne skyvekraft i en drivaksel ikke er vesentlig innen bilindustrien. Aksialt virkende krefter i en slik drivaksel er minimale. As mentioned, the known constant speed links are designed for use in cars. These joints cannot normally be subjected to large thrust forces in more than one direction. This is not a significant weakness in the aforementioned application area, as the need to use this thrust in a drive shaft is not significant within the automotive industry. Axially acting forces in such a drive shaft are minimal.
Den foreliggende oppfinner har nå funnet at et jevnhastighetsledd av den aktuelle type med enkle midler kan tilpasses for bruk om bord i småbåter som fleksibelt drivledd mellom propellakselen og girkassen om bord i båten. Så vidt man kjenner til, har et slikt ledd ikke tidligere vært påtenkt for benyttelse på det maritime område, dvs. for båtdrift, slik at dette vil være en helt ny anvendelse av jevnhastighetsleddet. The present inventor has now found that a constant speed link of the type in question can be adapted by simple means for use on board small boats as a flexible drive link between the propeller shaft and the gearbox on board the boat. As far as is known, such a joint has not previously been intended for use in the maritime area, i.e. for boating, so that this will be a completely new application of the constant speed joint.
Fra den kjente teknikk skal det vises til WO 2007/036237 vedrørende et dreieledd, DE 102006058860 vedrørende et dreieledd, og JP 2001065592 vedrørende et kardangledd for skip. From the prior art, reference should be made to WO 2007/036237 regarding a pivot joint, DE 102006058860 regarding a pivot joint, and JP 2001065592 regarding a gimbal joint for ships.
Det er således et formål med oppfinnelsen å tilveiebringe et jevnhastighetsledd som er egnet for benyttelse som drivledd for fremdrift av båter. It is thus an object of the invention to provide a constant speed link which is suitable for use as a drive link for the propulsion of boats.
I følge oppfinnelsen, løses de overnevnte problemer ved en anordning angitt i krav 1 og som har de karakteristiske trekk som angitt i den kjennetegnende del av kravet; og en anvendelse angitt i krav 3. According to the invention, the above-mentioned problems are solved by a device stated in claim 1 and which has the characteristic features as stated in the characterizing part of the claim; and an application specified in claim 3.
For oppnåelse av dette formål er det tilveiebrakt et drivledd av den innledningsvis angitte type som ifølge oppfinnelsen er kjennetegnet ved at det til leddets utgangsaksel er festet en låsering som er anbrakt ved akselens indre eller frie ende og er dimensjonert for å oppta trekkrefter fra propellen under drift, idet huset overfor utgangsakselens indre ende har en åpning for direkte tilgang til låseringen ved montering og demontering av drivleddet. To achieve this purpose, a drive joint of the type indicated at the outset has been provided which, according to the invention, is characterized by the fact that a locking ring is attached to the output shaft of the joint, which is placed at the inner or free end of the shaft and is sized to absorb traction forces from the propeller during operation , as the housing opposite the inner end of the output shaft has an opening for direct access to the locking ring when mounting and dismounting the drive link.
Da det dreier seg om en helt ny anvendelse av drivleddet, er det ifølge oppfinnelsen også tilveiebrakt en anvendelse av et drivledd som har et fleksibelt ledd for overføring av dreiebevegelse, som drivledd mellom en girkasse og en propellaksel om bord i en båt, idet drivleddet er konstruert for å oppta både trekk- og skyvekrefter fra propellen under drift. As it concerns a completely new application of the drive link, according to the invention, there is also an application of a drive link which has a flexible link for the transmission of turning movement, as a drive link between a gearbox and a propeller shaft on board a boat, as the drive link is designed to absorb both thrust and thrust forces from the propeller during operation.
Ved anvendelse av drivleddet for fremdrift av båter er det vesentlig at leddet kan oppta og tåle skyvekrefter som virker begge veier, nærmere bestemt skyvekrefter som utøves av propellen når båten beveger seg forover, og trekkrefter som utøves av propellen når båten beveger seg akterover. Leddets oppgave er å overføre en dreiebevegelse under et gitt dreiemoment med stadige små vinkelendringer mellom leddets inngående og utgående deler på grunn av båtens bevegelser i sjøen under drift. Når båten går forover og motoren skyves fremover på grunn av trykket fra propellen, vil denne kraft frembringe en liten vinkelendring. Det samme forhold, men i motsatt retning, gjør seg gjeldende når båten går akterover. I en båt uten noen form for fleksibelt element ville dette gi betydelige vibrasjoner. Med drivleddet ifølge oppfinnelsen er dette problem eliminert. En meget vesentlig fordel med dette ledd er dessuten at vinkelavvikets størrelse kan være opptil 7-8 grader, noe som er helt unikt i denne sammenheng. When using the drive joint for the propulsion of boats, it is essential that the joint can absorb and withstand thrust forces that act in both directions, more specifically thrust forces exerted by the propeller when the boat moves forward, and pulling forces exerted by the propeller when the boat moves astern. The joint's task is to transmit a turning movement under a given torque with constant small angle changes between the joint's input and output parts due to the boat's movements in the sea during operation. When the boat moves forward and the engine is pushed forward due to the pressure from the propeller, this force will produce a small angle change. The same relationship, but in the opposite direction, applies when the boat goes astern. In a boat without any kind of flexible element, this would cause significant vibrations. With the drive link according to the invention, this problem is eliminated. A very significant advantage of this joint is also that the size of the angular deviation can be up to 7-8 degrees, which is completely unique in this context.
Oppfinnelsen skal beskrives nærmere i det følgende i forbindelse med et utførelseseksempel under henvisning til tegningene, der The invention shall be described in more detail in the following in connection with an exemplary embodiment with reference to the drawings, there
fig. 1 viser et langsgående aksialsnitt av et drivledd ifølge oppfinnelsen, etter linjen I-l på fig. 2, fig. 1 shows a longitudinal axial section of a drive link according to the invention, along the line I-1 in fig. 2,
fig. 2 viser et enderiss av drivleddet sett i retning av pilen A på fig. 1, fig. 2 shows an end view of the drive link seen in the direction of arrow A in fig. 1,
fig. 3 viser et tilsvarende aksialsnitt som på fig. 1, men med snittet tatt i et plan hvor leddets kuler ikke er synlige, og fig. 3 shows a corresponding axial section as in fig. 1, but with the section taken in a plane where the balls of the joint are not visible, and
fig. 4 viser et gjennomskåret perspektivriss av drivleddet, med samme snittplan som på fig. 1. fig. 4 shows a sectional perspective view of the drive link, with the same sectional plane as in fig. 1.
I utgangspunktet er drivleddet ifølge oppfinnelsen en industriutgave av et drivledd for bil, hvor leddet er modifisert for å oppta skyvekrefter i begge retninger, og samtidig er utformet for lettvint montering og demontering om bord i en båt. Basically, the drive joint according to the invention is an industrial version of a drive joint for cars, where the joint is modified to absorb thrust forces in both directions, and at the same time is designed for easy assembly and disassembly on board a boat.
Slik det fremgår av tegningene, omfatter drivleddet 1 et utvendig hus 2 som omslutter et fleksibelt ledd 3 som er konstruert for å overføre et vridningsmoment og samtidig oppta skyve- eller trekkrefter som forårsakes av propellen under drift, samtidig som leddet tillater opptredende vinkelendringer mellom leddets inngående og utgående deler. Leddets 3 oppbygning skal beskrives nærmere senere. As can be seen from the drawings, the drive link 1 comprises an outer housing 2 which encloses a flexible link 3 which is designed to transmit a torque and at the same time absorb pushing or pulling forces caused by the propeller during operation, while the link allows for angular changes occurring between the input of the link and outgoing parts. The structure of section 3 will be described in more detail later.
Drivleddet omfatter videre en utgangsaksel 4 som ved sin ytre ende er utformet med et koplingshode 5 med en fordypning for opptakelse av en klemring 6 for fastspenning av en propellaksel for den aktuelle propell (ikke vist). Ved drivleddets andre ende er huset 2 forsynt med en flens 7 med fire hull 8 for festebolter for fastspenning av drivleddet til en utgangsaksel (ikke vist) fra en drivenhet, i dette tilfellet en girkasse, om bord i den aktuelle båt. The drive link further comprises an output shaft 4 which at its outer end is designed with a coupling head 5 with a recess for receiving a clamping ring 6 for clamping a propeller shaft for the relevant propeller (not shown). At the drive link's other end, the housing 2 is provided with a flange 7 with four holes 8 for fastening bolts for clamping the drive link to an output shaft (not shown) from a drive unit, in this case a gearbox, on board the boat in question.
Mellom drivleddets ytre hus 2 og utgangsakselen 4 er det som vist anordnet en tettende gummibelg 9 som ved den ene ende er festet til akselen 4 og ved den andre ende er festet til huset 2 via et tettende deksel 10. Between the drive joint's outer housing 2 and the output shaft 4, as shown, there is arranged a sealing rubber bellows 9 which is attached to the shaft 4 at one end and is attached to the housing 2 via a sealing cover 10 at the other end.
I den viste utførelse inneholder det fleksible ledd 3 seks kuler 11 som er anbrakt i tilpassede åpninger i en kuleholder i form av et såkalt kulegitter 12, på tilsvarende måte som i et kulelager. Kulene kan beveges i langsgående ytre og indre, krumme baner samtidig som de overfører et vridningsmoment. Således er ytre krumme baner 13 dannet i det ytre hus 2, og indre krumme baner 14 er dannet i en indre ring 15. Den indre ring 15 er dreiefast festet til utgangsakselen 4 ved at ringen er forsynt med en innvendig fortanning med langsgående tenner (ikke synlige på tegningene) som griper inn i tilsvarende tenner (heller ikke synlige) som er dannet i akselens overflate. Krumningen av de indre og ytre baner er tilpasset til hverandre på en slik måte at kulene 11 hele tiden ligger an mot både den indre og den ytre bane ved opptredende vinkelendringer mellom huset 2 og utgangsakselen 4. Banene er overflateherdet og slipt, slik at friksjonen mellom kulene og banene minimeres. In the embodiment shown, the flexible link 3 contains six balls 11 which are placed in adapted openings in a ball holder in the form of a so-called ball grid 12, in a similar way as in a ball bearing. The balls can be moved in longitudinal outer and inner curved paths while transmitting a torque. Thus, outer curved paths 13 are formed in the outer housing 2, and inner curved paths 14 are formed in an inner ring 15. The inner ring 15 is rotatably attached to the output shaft 4 by the ring being provided with an internal toothing with longitudinal teeth (not visible in the drawings) which engage corresponding teeth (also not visible) which are formed in the surface of the shaft. The curvature of the inner and outer tracks is adapted to each other in such a way that the balls 11 constantly rest against both the inner and the outer track when there are angular changes between the housing 2 and the output shaft 4. The tracks are surface hardened and ground, so that the friction between the spheres and paths are minimized.
Slik som foran nevnt, er drivleddet konstruert slik at det opptar både trekk- og skyvekrefter fra propellen under drift. Når båten beveger seg forover, opptas skyvekraften fra propellen av kulene 11, idet disse presses mot kulebanene på grunn av disses innbyrdes konvergerende forløp i fremoverretningen. Når båten beveger seg akterover, opptas trekkraften fra propellen via kulene 11 og ved hjelp av en låsering 16 som er festet i et periferisk spor i utgangsakselen ved dennes frie eller indre ende, idet låseringen der ligger an mot en tilstøtende sidekant av den indre ring 15. Låseringen er dimensjonert tilstrekkelig kraftig til å tåle de opptredende trekkrefter fra porpellen. Låseringen kan hensiktsmessig være en seegerring, slik det fremgår av fig. 4. As previously mentioned, the drive link is designed so that it absorbs both pulling and pushing forces from the propeller during operation. When the boat moves forward, the thrust from the propeller is taken up by the balls 11, as these are pressed against the ball tracks due to their mutually converging course in the forward direction. When the boat moves astern, the traction force from the propeller is taken up via the balls 11 and by means of a locking ring 16 which is fixed in a circumferential groove in the output shaft at its free or inner end, the locking ring there abutting against an adjacent side edge of the inner ring 15 The locking ring is designed to be strong enough to withstand the tensile forces from the porcelain. The locking ring can suitably be a seeger ring, as can be seen from fig. 4.
Når overføring av krefter skjer idet drivleddet har en gitt vinkel mellom de inngående og utgående deler, retter de enkelte deler seg inn etter vinkelens størrelse, mens selve kraftoverføringen ikke endres i det hele tatt. Avhengig av vinkelens størrelse vil kulene vandre frem og tilbake i sine baner, samtidig som de presses mot kulebanene når propellen utøver skyvekraft eller trekkraft på leddet. When the transmission of forces takes place when the drive link has a given angle between the input and output parts, the individual parts adjust according to the size of the angle, while the power transmission itself does not change at all. Depending on the size of the angle, the balls will travel back and forth in their paths, while at the same time they are pressed against the ball paths when the propeller exerts a pushing force or a pulling force on the joint.
Slik det fremgår av tegningene, er det utvendige hus 2 forsynt med en åpning 17 like overfor utgangsakselens 4 frie eller indre ende. Ved hjelp av åpningen oppnås direkte tilgang til låseringen 16, og derved lettvint montering og demontering av drivleddet. As can be seen from the drawings, the outer housing 2 is provided with an opening 17 just opposite the free or inner end of the output shaft 4. With the help of the opening, direct access to the locking ring 16 is obtained, and thereby easy assembly and disassembly of the drive link.
Drivleddet ifølge oppfinnelsen vil på mange måter representere en revolusjon i båtmarkedet. En båtprodusent vil med dette ledd kunne montere motor og gir i forhold til propellakselen på vesentlig kortere tid enn før, samtidig som resultatet blir mye bedre. Dessuten vil etterjustering være unødvendig da leddet opptar forekommende bevegelse. Store båter vil i tillegg ha en viss bevegelse i skroget. Alt dette har tradisjonelt vært et problem i alle båter med propellakseldrift. Disse problemer elimineres ved hjelp av det foreliggende drivledd. The drive joint according to the invention will in many ways represent a revolution in the boat market. With this part, a boat manufacturer will be able to mount the engine and gear in relation to the propeller shaft in a significantly shorter time than before, while at the same time the result will be much better. Furthermore, readjustment will be unnecessary as the joint takes up the movement that occurs. Large boats will also have some movement in the hull. All this has traditionally been a problem in all boats with propeller shaft drive. These problems are eliminated with the help of the present drive link.
