Description

Foreliggende oppfinnelse vedrører et system for kraft-overføring fra en hovedmotor til en generator. Det kali f.eks. benyttes i forbindelse med hovedfremdriftsmaskineriet for et fartøy når en elektrisk generator og fremdrifts--innretningen for fartøyet drives av samme motor, som løper med variabel hastighet. Systemet omfatter en justerbar hydraulisk kraftoverføring som er koblet for å The present invention relates to a system for power transmission from a main engine to a generator. That kali e.g. used in connection with the main propulsion machinery for a vessel when an electric generator and the propulsion device for the vessel are powered by the same engine, which runs at variable speed. The system comprises an adjustable hydraulic power transmission which is connected to

regulere hastighetsforholdet mellom motor og generator.regulate the speed ratio between engine and generator.

Et fartøy har vanligvis en hpved-dieselmotor somA vessel usually has an hpved diesel engine which

primær kraftkilde. Denne motor løper innenfor et bred-: hastighetsområde, hovedsakelig for fremdrift av fartøyet ved hjelp av en propeller e.l. Andre enheter kan være forbundet med hovedmotoren, såsom fartøyets elektriske generator. Et strukturelt ukomplisert arrangement oppnås ved å forbinde fartøyets f remdrif tssystem, dvs. propeli.eren,. propellerakselen og vanligvis også et reduksjonsgear, primary power source. This engine runs within a wide speed range, mainly for propulsion of the vessel by means of a propeller or the like. Other devices may be connected to the main engine, such as the vessel's electrical generator. A structurally uncomplicated arrangement is achieved by connecting the vessel's propulsion system, i.e. the propeller. the propeller shaft and usually also a reduction gear,

sammen med den elektriske generator med hovedmotorens drivaksel. together with the electric generator with the main engine drive shaft.

Det fleste fartøy benytter vekselstrøm i sitt elektriske system. Ved drift av en vekselstrømgenerator e:: det viktig at generatorens hastighet er praktisk talt konstant. Dette betyr at når hovedmotorens hastighet reduseres, må hastighetsforholdet mellom motor og generator endres. Den mest vanlige ulempe ved tidligere kjente anordninger for dette formål er deres langsomme virkning, som gir betydelig variasjon i generatorens hastighet. Most vessels use alternating current in their electrical system. When operating an alternating current generator it is important that the speed of the generator is practically constant. This means that when the main engine speed is reduced, the speed ratio between engine and generator must change. The most common disadvantage of previously known devices for this purpose is their slow operation, which gives considerable variation in the speed of the generator.

Et formål med oppfinnelsen er å tilveiebringe en variabel kraftoverføring for dieseldrevne synkrone gene-ratorer, ved hjelp av hvilken generatorens hastighet kan holdes praktisk talt konstant til tross for endringer i dieselmotorens hastighet. Et ytterligere formål er å tilveiebringe et system som er billig, konstruktivt ukomplisert og lett å vedlikeholde. An object of the invention is to provide a variable power transmission for diesel-driven synchronous generators, by means of which the speed of the generator can be kept practically constant despite changes in the speed of the diesel engine. A further object is to provide a system which is inexpensive, structurally uncomplicated and easy to maintain.

Oppfinnelsens formål oppnås ved hjelp av en konstruk-sjon som definert i krav 1. Ved hjelp av systemets hydrauliske kraftoverføring oppnår man en pålitelig og enkelJ Lj-uste-r-i-ng—av--hastighets-forhol-de-1^me-l-lom-mo-tor—og—genera to-r. The object of the invention is achieved by means of a construction as defined in claim 1. By means of the system's hydraulic power transmission, a reliable and simple Lj-uste-r-i-ng—of--speed-ratio-1^me-l is achieved -lom-mo-tor—and—genera to-r.

En effektiv kombinasjon av de nødvendige måle- og reguleringsinnretninger oppnås på følgende måte: En hydraulisk pumpe drives av en motoraksel og er forbuildet med en fluidummotor ved hjelp av en hydraulisk krets. Fluidummotoren er forbundet med solhjulet i et planetgéar, idet planetgearets ringhjul er forbundet med motorakselen An effective combination of the necessary measuring and regulating devices is achieved in the following way: A hydraulic pump is driven by a motor shaft and is pre-built with a fluid motor by means of a hydraulic circuit. The fluid motor is connected to the sun gear in a planetary gear, the ring gear of the planetary gear being connected to the motor shaft

The shaft 9 of the generator 5 is connected to the planetary gear holder 8 of the planetary gear. A centrifugal regulator 3 is connected to the generator shaft 9 by means of a pair of gears 3a. The centrifugal regulator 3

er koblet slik at den justerer pumpen 1 ved hjelp av en regulatorarm 3c og en overføringsstang 3b. På denne måte reguleres kapasiteten av den hydrauliske pumpe 1 av gene>-ratorens virkelige hastighet. Kraftoverføringen mellom motorakselen 14 og den hydrauliske pumpe 1 er ordnet ved is connected so that it adjusts the pump 1 by means of a regulator arm 3c and a transfer rod 3b. In this way, the capacity of the hydraulic pump 1 is regulated by the actual speed of the generator. The power transmission between the motor shaft 14 and the hydraulic pump 1 is arranged by

hjelp av tannhjul 11 og 12. Hovedelementene i kraftover--føringssystemet er innelukket i et hus 16, som har egnede understøttelser 18 for lagrene 17 for de forskjellige aksler. Reguleringen av hastighetsforholdet motor-generator skjer som følger: Sentrifugalregulatoren 3 føler en endring i generatorakselens 9 hastighet og bevirker en slaglengde-justering i den hydrauliske pumpe 1. Ved hydraulisk over-føring gjennom kretsen 13 bevirker dette en endring i hastigheten av fluidummotoren 2, som driver planetgearets solhjul 61 Derved forandres hastigheten av planetgearelementene "tilsvarende for å kompensere for den endring i generatorak- . '; selens 9 hastighet som opprinnelig ble følt av sentrifugalregulatoren 3. using gears 11 and 12. The main elements of the power transmission system are enclosed in a housing 16, which has suitable supports 18 for the bearings 17 for the various axles. The regulation of the motor-generator speed ratio takes place as follows: The centrifugal regulator 3 senses a change in the speed of the generator shaft 9 and causes a stroke length adjustment in the hydraulic pump 1. In the case of hydraulic transmission through the circuit 13, this causes a change in the speed of the fluid motor 2, which drives the planet gear's sun wheel 61 Thereby, the speed of the planet gear elements is changed "correspondingly to compensate for the change in generator ac- . '; the speed of the seal 9 originally sensed by the centrifugal regulator 3.

I den viste utførelse er generatoren 5 forbundet med motoren 4 på samme side som fremdriftsakselen 15. Det er også mulig å montere generatoren og fremdriftsakselen i motsatte ender av motoren 4. In the embodiment shown, the generator 5 is connected to the motor 4 on the same side as the drive shaft 15. It is also possible to mount the generator and the drive shaft at opposite ends of the motor 4.

Oppfinnelsen er ikke begrenset til det viste utførel-seseksempel, men kan modifiseres på mange måter innen rammen av de påfølgende krav. The invention is not limited to the embodiment shown, but can be modified in many ways within the scope of the following claims.
