Description
Oppfinnelsen vedrører en anordning ved en generator, særlig The invention relates to a device for a generator, in particular
en generator uten børster og med enkel opplagring av rotoren, hvilken generator er montert på en drivmotor. a generator without brushes and with simple storage of the rotor, which generator is mounted on a drive motor.
Fra de polske patenter nr. 84307 og 90516 er det kjent børste-løse generatorer oppbygget som elektriske strømforsyningssett hvor den indre statorpakke er montert på en hylse med en ende-eller frontplate som utgjør en del av generatorhuset. Rotorens bæreplate kan være montert på en flens på drivakselen. Gener-atorhusene er monterbare på drivmotoren ved hjelp av flenser. From the Polish patents Nos. 84307 and 90516, brushless generators constructed as electric power supply sets are known, where the inner stator pack is mounted on a sleeve with an end or front plate which forms part of the generator housing. The rotor support plate can be mounted on a flange on the drive shaft. The generator housings can be mounted on the drive motor using flanges.
De kjente og hittil anvendte løsninger har visse ulemper. Viklingen og impregneringen av den indre statorpakke er van-skelig. Den ekstra aksel, som er montert i bæreplaten ved hjelp av en flens med liten diameter -og tykkelse, gir ingen garanti for koaksialiteten med drivakselen. The known and hitherto used solutions have certain disadvantages. The winding and impregnation of the inner stator pack is difficult. The additional shaft, which is mounted in the carrier plate by means of a flange of small diameter and thickness, does not guarantee the coaxiality with the drive shaft.
Luftstrømmene som skal kjøle det indre av generatoren, fordeles ikke jevnt, og det foreligger derfor en fare for lokale over-hetinger. The air currents that are to cool the interior of the generator are not evenly distributed, and there is therefore a risk of local overheating.
Hensikten med foreliggende oppfinnelse er å råde bot på de nevnte ulemper. The purpose of the present invention is to remedy the aforementioned disadvantages.
Ifølge oppfinnelsen har man oppnådd gode resultater ved å benytte en hylse mellom den indre stator og endeplaten. En flens på motorens drivaksel er aksialt innpasset i en større og tykkere flens på en tilleggsaksel eller akselforlengelse, og på denne større og tykkere flens er rotorens bæreplate montert. De roterende deler virker som en vifte og er utformet for retting av luftstrømmen i ønsket grad. Statorhylsen er utformet med ribber slik at man får en fordelaktig luft-strøm. According to the invention, good results have been achieved by using a sleeve between the inner stator and the end plate. A flange on the motor drive shaft is axially fitted into a larger and thicker flange on an additional shaft or shaft extension, and on this larger and thicker flange the rotor bearing plate is mounted. The rotating parts act like a fan and are designed to direct the air flow to the desired degree. The stator sleeve is designed with ribs so that an advantageous air flow is obtained.
Det som særlig utmerker oppfinnelsen er at man lettere får adgang til roterende deler, sammenlignet med de hittil kjente konstruksjoner. Anordning av mannhull med tilsvarende lokk for vedlikehold og reparasjoner av rotoren uten demontering av hele generatoren, og dette betyr store arbeidsbesparelser. Den nye opplagring av bæreplaten gir større stivhet og for-enkler tilpassingen og monteringen av rotoren. For å stive av generatorsettet kan huset fordelaktig forsynes med utspring med ører, hvilke utspring eliminerer tverrforskyvninger. What particularly distinguishes the invention is that it is easier to get access to rotating parts, compared to the hitherto known constructions. Arrangement of manholes with corresponding covers for maintenance and repairs of the rotor without dismantling the entire generator, and this means great labor savings. The new storage of the carrier plate provides greater rigidity and simplifies the adjustment and installation of the rotor. To stiffen the generator set, the housing can advantageously be provided with protrusions with ears, which protrusions eliminate transverse displacements.
Oppfinnelsen skal beskrives nærmere under henvisning til tegningene hvor: fig. 1 viser et halvsnitt gjennom generatoren og fig. 2 viser et frontriss av generatoren. ' The invention shall be described in more detail with reference to the drawings where: fig. 1 shows a half section through the generator and fig. 2 shows a front view of the generator. '
Som det går frem av fig. 1 er en hylse 1 forbundet med en endeplate 2 i generatorhuset med en radiell klaring 13 til en akselforlengelse 5. I den fremre del er hylsen utformet med et lagerkammer 12. Navet til endeplaten 2 er presset på hylsen 1 og er sikret ved hjelp av en settskrue 18. As can be seen from fig. 1, a sleeve 1 is connected to an end plate 2 in the generator housing with a radial clearance 13 to a shaft extension 5. In the front part, the sleeve is designed with a bearing chamber 12. The hub of the end plate 2 is pressed onto the sleeve 1 and is secured by means of a set screw 18.
Rotoren 4 er montert på en bæreplate 3 ved hjelp av skruer 17. Bæreplaten 3 er ved hjelp av skruer 19 festet til flensen på akselforlengelsen 5. Akselforlengelsen er flenset på motorakselen 6. For dette formål benyttes det skruer 20.. Endeplaten 2 er forsynt med mannhull 8 som er tildekt med lokk 9. Luftstrømmen som kommer fra utsiden styres således gjennom åpningene 7. Et sylinderskjold 14 på innsiden av endeplaten 2 retter luften i retning mot åpningene 16 og 11. Ved åpning-en 11 er det anordnet skjermplater 10 i form av ribber for styring av kjølingen. På bæreplaten 3 er det anordnet en starttannring 15. Huset er forsynt med utspring med ører. The rotor 4 is mounted on a carrier plate 3 by means of screws 17. The carrier plate 3 is attached to the flange of the shaft extension 5 by means of screws 19. The shaft extension is flanged to the motor shaft 6. For this purpose, screws 20 are used. The end plate 2 is provided with manhole 8 which is covered with a lid 9. The air flow coming from the outside is thus controlled through the openings 7. A cylinder shield 14 on the inside of the end plate 2 directs the air in the direction of the openings 16 and 11. At the opening 11 there are screen plates 10 in the form of ribs for controlling the cooling. A starting toothed ring 15 is arranged on the support plate 3. The housing is provided with protrusions with ears.
Oppfinnelsen er særlig tenkt anvendt i forbindelse med motor-generatorsett. Ved større totaldimensjoner for generatoren kan det for avstivning og eliminering av tverrforskyvninger anordnes spesielle flenser eller ører i forbindelse med ut-springene . The invention is particularly intended to be used in connection with motor-generator sets. In the case of larger overall dimensions for the generator, special flanges or lugs can be arranged in connection with the protrusions to stiffen and eliminate transverse displacements.
