Description
30 5172566 Uppfinningen förklaras närmare i det följande genom ett utföringsexempel. På de tillhörande ritningama visar schematiskt: Fig. 1: ett fartygsdrivmaskineri, Fig. 2: detaljen II från Fig. 1. The invention is explained in more detail in the following by means of an exemplary embodiment. In the accompanying drawings schematically shows: Fig. 1: a ship propulsion machinery, Fig. 2: detail II from Fig. 1.
Fig. 1 visar ett fartygsdrivmaskineri, vid vilket en propeller 1 via en drivaxel 2 med mellankoppling hos en hydraulisk säkerhetskoppling 3 är förbunden med en huvudmotor 4. Fartygsdrivmaskineriet innehåller vidare ett nödmaskineri 5, vars hjälpmotor 6 via en växel 7 är kopplingsbar med drivaxeln 2 inom området mellan propellem 1 och den hydrauliska säkerhetskopplingen 3. Fig. 1 visar vidare ett stävrör 8, genom vilket drivaxeln 2 sträcker sig in i skrovet utifiån, ett axellager 9, en hylskoppling 10, en propeller-justeringsenhet ll och en elastisk koppling 12.Fig. 1 shows a ship propulsion machinery, in which a propeller 1 via a drive shaft 2 with intermediate coupling of a hydraulic safety clutch 3 is connected to a main engine 4. The ship propulsion machinery further contains an emergency machinery 5, the auxiliary engine 6 via a gear 7 can be coupled to the drive shaft 2 within the area between the propeller 1 and the hydraulic safety coupling 3. Fig. 1 further shows a stem tube 8, through which the drive shaft 2 extends into the hull from the outside, a shaft bearing 9, a sleeve coupling 10, a propeller adjusting unit 11 and an elastic coupling 12.
Som hydraulisk säkerhetskoppling kommer med fördel till användning en Safe-set- eller Hyguard-koppling. Dessa kopplingar är för fackmarmen välbekanta och kan köpas i fackhandeln. Den hydrauliska säkerhetskopplingen 3 (Fig. 2) innehåller ett vid drivaxelns 2 ände skjutbart kopplingsnav 13 med fläns. Vid kopplingsnavet 13 finns två bredvid varandra spännelement 14, 15. Varje spärmelement 14, 15 innehåller ett trycksystem 16, 17, vilket var och ett innehåller en med ett flytande medium fylld tryckkamrnare 18, 19, vilken, under tryck, år stängningsbar med en ventil 20, 21.A safe-set or Hyguard coupling can be used as a hydraulic safety coupling. These connections are familiar to the specialist arm and can be bought in specialist shops. The hydraulic safety coupling 3 (Fig. 2) contains a coupling hub 13 slidable at the end of the drive shaft 2 with fl äns. At the coupling hub 13 there are two adjacent clamping elements 14, 15. Each locking element 14, 15 contains a pressure system 16, 17, each of which contains a pressure chamber 18, 19 filled with a surface medium, which, under pressure, can be closed with a valve 20, 21.
Trycksystemen 16, 17 är avlastningsbara genom öppning av dess ventiler 20, 21 med hjälp av fjärrmanövrerade öppningsmekanismer 22, 23. Enligt utföringsexemplet ankommer på fartygsäkerhetssystemet 24 kopplade elektriska lyftmagneter till användning, vars ankare är rörligai ventilernas 20, 21 strömningskrets. Vid spännelementen 14, 15 fmns vidare ett telemetriskt system 25, vilket övervakar det hydrauliska trycket hos trycksystemen 16, 17 och signalerar ett tryckfall till fartygsäkerhetssystemet 24. Det telemetriska systemet 25 innehåller för varje trycksystem 16, 17 en tryckomvandlare, vilken motsvarande det förestående trycket ger en signal, som efter förstärkning sänds av en med spännelementen 14, 15 medroterande sändare med en lämplig antenn och som ges till fartygsäkerhetssystemet 20 25 30 517 566 3 24. Sådana överföringssystem är för fackmannen välbekanta och behövs därför inte närmare förklaras.The pressure systems 16, 17 can be relieved by opening their valves 20, 21 by means of remotely operated opening mechanisms 22, 23. According to the exemplary embodiment, coupled electric lifting magnets arrive at the ship safety system 24, the anchors of which are movable in the flow circuit of the valves 20, 21. At the clamping elements 14, 15 there is also a telemetric system 25, which monitors the hydraulic pressure of the pressure systems 16, 17 and signals a pressure drop to the ship safety system 24. The telemetric system 25 contains for each pressure system 16, 17 a pressure transducer, which gives the corresponding pressure a signal which, after amplification, is transmitted by a transmitter co-rotating with the clamping elements 14, 15 with a suitable antenna and which is given to the ship safety system 20 25 517 566 3 24. Such transmission systems are well known to those skilled in the art and therefore need not be explained in more detail.
Den hydrauliska säkerhetskopplingen 3 är enligt föreliggande exempel försedd med två trycksystem 16, 17. Det är även möjligt att använda ett trycksystem, dock förbättras redundansen med båda trycksystemen 16, 17 . Således kan vid bortfall av ett trycksystem 16, 17 huvudmotom 4 kopplas till drivaxeln 2 (vilket i det följande närmare kommer att förklaras) och blir så vidare belastat med vridmomentet från propellem 1 och säkrar därmed mot lastfii övervarvning.According to the present example, the hydraulic safety coupling 3 is provided with two pressure systems 16, 17. It is also possible to use a pressure system, however, the redundancy is improved with both pressure systems 16, 17. Thus, in the event of a failure of a pressure system 16, 17, the main motor 4 can be coupled to the drive shaft 2 (which will be explained in more detail below) and is thus further loaded with the torque from the propeller 1 and thus secures against load fi in overspeed.
För den normala driften står spärmelementens 14, 15 trycksystem 16, 17 under tryck.For normal operation, the pressure systems 16, 17 of the locking elements 14, 15 are under pressure.
Detta orsakar en töjning av spännelementen 14, 15 med en motsvarande kraftutövning på den hydrauliska säkerhetskopplingens 3 kopplingsnav 13. Kraftutövningen på kopplingsnavet 13 leder till dess fiíktionsförbindelse med drivaxeln 2. Därmed är trycket i trycksystemet så avpassat, att redan under verkan av ett spännelement 14, 15 kommer vridmomentet hos huvudmotom 4 överföras till drivaxeln 2.This causes an elongation of the clamping elements 14, 15 with a corresponding application of force on the coupling hub 13 of the hydraulic safety coupling 3. 15, the torque of the main motor 4 will be transmitted to the drive shaft 2.
Ifall av driftstöming styr fartygsäkerlretssystemet 24 öppningsmekanismenerna 22, 23.In the event of operational disturbance, the ship safety belt system 24 controls the opening mechanisms 22, 23.
Därmed rör sig deras ankare i ventilens 20, 21 strörnningskrets. Till följd härav stöter ventilema 20, 21 mot ankama och öppnar väg, varigenom tryckkanrrnama 18, 19 öppnas och dess tryck utjärnnas. Därigenom är inte kopplingsnavet 13 längre kraftpåverkat och friktionsförbindelsen mellan detta och drivaxeln 2 är upphävd.Thus, their anchors move in the strut circuit of the valve 20, 21. As a result, the valves 20, 21 abut the ankles and open a path, whereby the pressure vessels 18, 19 are opened and their pressure is equalized. As a result, the coupling hub 13 is no longer actuated and the frictional connection between it and the drive shaft 2 is canceled.
Följaktligen är kopplingsförbindelsen mellan huvudrnotorn 4 och drivaxeln 2 bruten.Consequently, the coupling connection between the main motor 4 and the drive shaft 2 is broken.
Vid den drivmässigt från huvudmotom 4 skilda drivaxeln 2 kan nu hjälpmotom 6 kopplas via växeln 7. Den vid denna nöddrift från propellem 1 alstrade, i drivaxeln 2 rådande axialkraften upptas av ett radiallager 26 hos den hydrauliska säkerhetskopplingen 3. Således stöder sig drivaxeln 2 via radiallagret 26 mot det stillastående kopplingsnavet 13, vars flank stödjer sig mot kraftuttagsflanken 27 hos huvudmotom 4. På så sätt är det överflödigt att använda ett speciellt axiallager för upptagrring av denna axiallcraft. 20 25 30 517 566 4 De hydrauliska trycksystemen 16, 17 kan även avlastas genom manuell öppning av ventilema 20, 21. Detta visar sig särskilt, då huvudmotorn vid ett haveri blockeras, emedan öppningsmekariismema 22, 23 då kan skiljas fiån de icke roterande ventilema 20, 21.In the case of the drive shaft 2 separated from the main motor 4, the auxiliary motor 6 can now be coupled via the gear 7. The axial force generated in this emergency drive from the propeller 1 is absorbed by a radial bearing 26 of the hydraulic safety clutch 3. Thus the drive shaft 2 is supported via the radial bearing 26 against the stationary clutch hub 13, the fl of which rests against the PTO shaft 27 of the main engine 4. In this way it is superfluous to use a special thrust bearing for receiving this thrust. The hydraulic pressure systems 16, 17 can also be relieved by manually opening the valves 20, 21. This is particularly evident when the main engine is blocked in the event of a breakdown, since the opening mechanisms 22, 23 can then be separated from the non-rotating valves 20. , 21.
Enligt utfóringsexemplet används som hydraulisk säkerhetskoppling 3 en fríktionskoppling, vid vilken drivaxeln 2 och kopplingsnavet 13 är förbundna med varandra friktionsbundet. Som hydraulisk säkerhetskoppling kan även andra friktionskopplingar användas, exempelvis lamellkopplingar, vilkas kopplingsskivor för alstrande av fiiktionsförbindelse är belastbara medelst ett eller flera hydrauliska trycksystem.According to the exemplary embodiment, a friction coupling is used as the hydraulic safety coupling 3, in which case the drive shaft 2 and the coupling hub 13 are frictionally connected to each other. As a hydraulic safety coupling, other friction couplings can also be used, for example lamella couplings, the coupling discs for generating a för connection are loadable by means of one or fl your hydraulic pressure systems.
