Description
Dynamodrivverk for skinnegående kjøretøy. Dynamo drive for rail vehicles.
Oppfinnelsen vedrorer et dynamodrivverk for skinnegående kjoretoy, med en klopolgenerator, som over et planetdrev er koblet til kjoretoyets hjulaksel. The invention relates to a dynamo drive for rail-running vehicles, with a klopole generator, which is connected via a planetary gear to the vehicle's wheel axle.
Det er kjent forskjellige utfbrelsesformer av togbelysnings-generatorer for direkte montering på en aksel, spesielt er det kjent slike generatorer i klopolform. Ved de kjente klopol-generatorer drives klopolrotoren via et enkelt, eller dobbelt sylindrisk tannhjul eller et vinkeldrev. Rotoraksen vil da bli utilsiktet, men på en uheldig måte bli liggende eksentrisk i forhold til vognakselen. På grunn av denne eksentriske anordning av generatoren vil det, særlig ved et stort omsetningsforhold, oppstå stort plassbehov og/eller en uheldig lokalisering av generatorens tyngdepunkt. Denne uheldige lokalisering har forst og fremst den ulempe at akselbbssingen på grunn av vektarmen på en uonsket måte utsettes for ekstra dynamiske påkj enninger. Different designs of train lighting generators for direct mounting on an axle are known, in particular such generators are known in clopole form. In the known klopol generators, the klopol rotor is driven via a single or double cylindrical gear or an angle drive. The rotor axis will then unintentionally, but in an unfortunate way, be located eccentrically in relation to the carriage axle. Because of this eccentric arrangement of the generator, there will be a large need for space and/or an unfortunate localization of the generator's center of gravity, especially with a high turnover ratio. This unfortunate location primarily has the disadvantage that the axle bearing is undesirably exposed to additional dynamic stresses due to the weight arm.
Den foreliggende oppfinnelse går ut på å unngå de nevnte ulem-per. Ifolge oppfinnelsen er dynamodrivverket karakterisert ved en med generatorens lagerplate fast forbundet hulaksel, The present invention aims to avoid the aforementioned disadvantages. According to the invention, the dynamo drive is characterized by a hollow shaft firmly connected to the generator's bearing plate,
som på sin ytterside bærer lageret for generatorrotoren og i hvis boring det er lagret en med drivakselen koblet koaksial aksel i hvis frie ende planethjulbæreren for planetdrevet er festet, hvorved planetdrevets ytterhjul står fast og solhjulet er forbundet med generatorrotoren. which on its outer side carries the bearing for the generator rotor and in whose bore a coaxial shaft connected to the drive shaft is stored, at the free end of which the planet gear carrier for the planetary drive is attached, whereby the outer wheel of the planetary drive is fixed and the sun gear is connected to the generator rotor.
Oppfinnelsen skal i det folgende beskrives nærmere under hen-visning til tegningen, som viser et utfbrelseseksempel i lengde-snitt. In the following, the invention will be described in more detail with reference to the drawing, which shows an exemplary embodiment in longitudinal section.
En jernbanevogn har en hulaksel 1, som via et rullelager 2 er lagret i en akselbossing 3. I stedet for det vanlige deksel er det på den åpne ende av akselbossingen 3 skrudd fast en lagerplate 4 over et elastisk mellomledd 5, som f.eks. består av gummi. A railway carriage has a hollow axle 1, which via a roller bearing 2 is stored in an axle boss 3. Instead of the usual cover, a bearing plate 4 is screwed onto the open end of the axle boss 3 over an elastic intermediate link 5, which e.g. consists of rubber.
Lagerplaten 4 er utstyrt med en hulaksel 6, som er koaksial The bearing plate 4 is equipped with a hollow shaft 6, which is coaxial
med vognakselen 1 og er fast anordnet på lagerplaten. I hul-akselens 6 boring er det anordnet et nållager 7 for en aksel 9, som via en skjematisk vist, elastisk kobling 8 er koaksialt forbundet med vognakselen 1 og hvis akselende lo rager ut over hulakselen 6. with the carriage axle 1 and is fixed on the bearing plate. In the bore of the hollow shaft 6 there is arranged a needle bearing 7 for a shaft 9, which via a schematically shown, elastic coupling 8 is coaxially connected to the carriage shaft 1 and whose shaft end lobe protrudes above the hollow shaft 6.
Hulakselens 6 ytterflate bærer et kulelager 11, og et klopol-hjul 12.med poltagger 13 er via kulelageret 11 lagret på hulakselen 6. For opptagelse av kulelageret 11 har polhjulet 12 The outer surface of the hollow shaft 6 carries a ball bearing 11, and a pole wheel 12 with pole tags 13 is stored on the hollow shaft 6 via the ball bearing 11. To accommodate the ball bearing 11, the pole wheel 12 has
et nav 14 som er utformet som en hul sylinder. Ytterligere et polhjul 15 med poltagger 16 er konsentrisk forbundet med polhjulet 12. For forbindelse og sentrering av.de to polhjul 12 a hub 14 which is designed as a hollow cylinder. A further pole wheel 15 with pole tags 16 is concentrically connected to the pole wheel 12. For connection and centering of the two pole wheels 12
og 15 er det anordnet en ikke magnetisk avstandshylse 17, som and 15, a non-magnetic spacer sleeve 17 is arranged, which
f.eks. kan være sveiset fast på polhjulene. e.g. may be welded to the pole wheels.
Klopolhjulene 12,15 roterer innenfor boringen for en stator 18, som er festet til en husmantel 19, som er anordnet på lagerplaten 4. Konsentrisk med statoren 18, som er forsynt med en vikling 2o, er det anordnet en stasjonær magnetiseringsvikling 21. Som bærer for magnetiseringsviklingen 21 er det anordnet en hulsylindrisk bærering 22, som består av et magnetisk ledende materiale og er festet til lagerplaten 4. Bæreringen 22 danner på i og for seg kjent måte via tilsvarende sylindriske flater hver sin luftspalte 23 hhv. 24 med polhjulene 15,12. Luft-spaltene er kortest mulig, men har storst mulig tverrsnitt for at det skal oppnås en ringe magnetisk motstand. Den indre magnetiske shunt mellom klopolhjulene 12 og 15 forloper her over de to luftspalter 23,24 og bæreringen 22, mens den ytre shunt forloper over statoren 18. The claw wheels 12, 15 rotate within the bore for a stator 18, which is attached to a casing 19, which is arranged on the bearing plate 4. Concentrically with the stator 18, which is provided with a winding 2o, a stationary magnetizing winding 21 is arranged. As carrier for the magnetizing winding 21, a hollow cylindrical support ring 22 is arranged, which consists of a magnetically conductive material and is attached to the bearing plate 4. The support ring 22 forms, in a manner known per se, via corresponding cylindrical surfaces each an air gap 23 or 24 with the pole wheels 15,12. The air gaps are as short as possible, but have the largest possible cross-section in order to achieve a low magnetic resistance. The inner magnetic shunt between the claw pole wheels 12 and 15 runs here over the two air gaps 23,24 and the support ring 22, while the outer shunt runs over the stator 18.
Klopolhjulet 12 er forsynt med en hulsylindrisk forlengelse 26, gjennom hvis boring akselen 9 er fort og hvis yttermantel er utformet som drev 27. The bell wheel 12 is provided with a hollow cylindrical extension 26, through whose bore the shaft 9 is driven and whose outer casing is designed as a drive 27.
På husmantelen 19 er det med ikke viste skrueorganer festet et husdeksel 29, som på sin innside via en hulsylindrisk bærering 3o bærer et fast tannhjul 31 med indre fortanning. Mellom det faste tannhjul 31 og drevet 27 er det anordnet tre med disse sam-virkende planethjul 32 for et planetgir. Planetgiret drives via tre armer 33, som er utformet som en trearmet stjerne, som i sentrum ved hjelp av en skruebolt 34 er festet på akselenden lo, som rager ut over drevet 27. Hver arm 33 er på sin ende forsynt med en aksial bolt 35, hvis akse er koaksial med planet-hjulets 32 akse og som via et kulelager 36 griper inn i planet-hjulets 32 sentrum. Det faste tannhjul 31 har et vesentlig storre, f.eks. seks ganger storre antall tenner enn drevet 27, slik at det fra drivanordningen, nemlig akselen 9 som er forbundet med vognakselen 1, hhv. armene 33 til den drevne anordning, nemlig drevet 27 hhv. polhjulet 12, fås et omsetningsforhold på 1:7 i det her omtalte tilfelle. On the housing casing 19, a housing cover 29 is attached with screw means not shown, which on its inside via a hollow cylindrical support ring 3o carries a fixed gear wheel 31 with internal toothing. Between the fixed gear wheel 31 and the drive 27 there are arranged three with these interacting planet wheels 32 for a planetary gear. The planetary gear is driven via three arms 33, which are designed as a three-armed star, which in the center by means of a screw bolt 34 is fixed to the shaft end lo, which protrudes above the drive 27. Each arm 33 is provided at its end with an axial bolt 35 , whose axis is coaxial with the axis of the planet wheel 32 and which via a ball bearing 36 engages in the center of the planet wheel 32. The fixed gear 31 has a substantially larger, e.g. six times greater number of teeth than the drive 27, so that from the drive device, namely the axle 9 which is connected to the carriage axle 1, respectively. the arms 33 of the driven device, namely driven 27 respectively. pole wheel 12, a turnover ratio of 1:7 is obtained in the case discussed here.
I husdekslet 29 er det anordnet en åpning 37, som kan lukkes utenfra og som gjor det mulig å losne skruebolten 34 utenfra og dermed demontere det omtalte planetgir. Tannhjulene 27,31,32 og armene 33 befinner seg i et oljebad som ved tetningsorganer 39 er avtettet overfor klopolgeneratoren med polhjulene 12 og 15 samt statoren 18. An opening 37 is arranged in the housing cover 29, which can be closed from the outside and which makes it possible to loosen the screw bolt 34 from the outside and thus dismantle the mentioned planetary gear. The gears 27, 31, 32 and the arms 33 are located in an oil bath which is sealed against the pole generator with the pole wheels 12 and 15 and the stator 18 by sealing means 39.
I figuren er de elektriske tilknytninger for den stasjonære statorvikling 2o og magnetiseringsviklingen 21 ikke vist. De opprettes på vanlig måte, f.eks. via tilknytningsledninger som er fort gjennom husmantelen 19 på siden og via regulatorer og likerettere i jernbanevognen er forbundet med togbelysningen og akkumulatorer. In the figure, the electrical connections for the stationary stator winding 20 and the magnetizing winding 21 are not shown. They are created in the usual way, e.g. via connection lines which are fast through the housing casing 19 on the side and via regulators and rectifiers in the railway carriage are connected to the train lighting and accumulators.
Den beskrevne klopolgenerator for direkte montering på aksel, spesielt på en jernbanevogn, har en rekke fordeler overfor de kjente generatorer. Fordi planetgiret og generatoren er utfort som en kompakt enhet som er konsentrisk med akselen, fås vesentlig mindre plassbehov enn ved den eksentriske anordning av kjente generatorer. Generatorrotorens lagring på en hulaksel bevirker at avstanden mellom generatorens tyngdepunkt og vogn-aksellageret blir liten og at det på grunn av den ringe vektarm oppnås lav dynamisk påkjenning på akselbossingen. Idet planetgiret som er anordnet på den ytre lagerside, er vesentlig lettere enn klopolgeneratoren, bevirker giret en meget ringe ekstra belastning på akselbossingen. Det forhold at giret er anordnet på utsiden av generatoren gjor dessuten giret lettere tilgjengelig og muliggjor en enkel overvåkning av giret, som er utsatt for storre slitasje enn generatoren. The described clopole generator for direct mounting on an axle, especially on a railway carriage, has a number of advantages over the known generators. Because the planetary gear and the generator are designed as a compact unit that is concentric with the shaft, significantly less space is required than with the eccentric arrangement of known generators. The storage of the generator rotor on a hollow shaft means that the distance between the generator's center of gravity and the carriage axle bearing becomes small and that, due to the low weight arm, a low dynamic stress is achieved on the axle boss. As the planetary gear which is arranged on the outer side of the bearing is significantly lighter than the klopole generator, the gear causes a very small additional load on the axle boss. The fact that the gear is arranged on the outside of the generator also makes the gear easier to access and enables easy monitoring of the gear, which is exposed to greater wear and tear than the generator.
Den elastiske opphengning av statoren og den elastiske kobling for forbindelse av vognakselen med giret gjor det også mulig å oppfange store akselerasjonskrefter, som oppstår ved hbye toghastigheter i forbindelse med skinnestbt, sporveksler m.v. The elastic suspension of the stator and the elastic coupling for connecting the carriage axle with the gear also make it possible to absorb large acceleration forces, which occur at high train speeds in connection with rail supports, track switches, etc.
En annen fordel ved den omtalte klopolgenerator er at rotoren ved samme tyngdepunktslokalisering kan ha storre diameter, slik at generatoren kan avgi en storre effekt. Det kan også oppnås et storre omsetningsforhold og dermed et hoyere rotorturtall Another advantage of the mentioned clopole generator is that the rotor can have a larger diameter at the same center of gravity location, so that the generator can emit a greater power. A greater turnover ratio and thus a higher rotor speed can also be achieved
uten ekstra plassbehov. without additional space requirements.
Endelig er det fordelaktig at den beskrevne generator vanligvis kan monteres uten efterarbeid på akselen og akselbossingen for en allerede eksisterende jernbanevogn. Finally, it is advantageous that the described generator can usually be mounted without rework on the axle and the axle boss for an already existing railway carriage.
