Description
Elektrisk maskin~nied liten ytelse, særlig en sykkeldynamo. Electric machine~nied small output, especially a bicycle dynamo.
Foreliggende oppfinnelse angår en The present invention relates to a
elektrisk maskin med liten ytelse, særlig en sykkeldynamo, med en spolekjerne til hvis ender er festet polsko, som omslutter rotoren og omgis av maskinens hus og hvor polskoenes ender ved hjelp av en egnet anordning avstøttes på husets innside. electrical machine of low output, in particular a bicycle dynamo, with a coil core to the ends of which pole shoes are attached, which enclose the rotor and are surrounded by the machine's housing and where the ends of the pole shoes are supported on the inside of the housing by means of a suitable device.
Erfaring har vist at elektriske maski-ner av ovenfor nevnte art i drift kan for-årsake en skranglelyd. Årsaken til denne lyd var i lang tid uforklarlig. Inngående undersøkelser viste til slutt at lyden frem-bringes av tiltrekningskreftene som utøves periodisk av rotoren på polskoene. Det viste seg at toleransene i den innvendige diameter av maskinens hus, i tykkelsen av polskoene eller støtteanordningens utven-dige diameter for de frie ender av polskoene, hadde til følge et spillerom mellom denne støtteanordning og de frie ender av polskoene, slik at disse fri ender periodisk kunne slå an mot støtteanordningen. Experience has shown that electrical machines of the above-mentioned kind in operation can cause a rattling sound. The cause of this sound was for a long time inexplicable. In-depth investigations finally showed that the sound is produced by the attraction forces exerted periodically by the rotor on the pole shoes. It turned out that the tolerances in the internal diameter of the machine's housing, in the thickness of the pole shoes or the outside diameter of the support device for the free ends of the pole shoes, resulted in a play between this support device and the free ends of the pole shoes, so that these free ends could periodically strike the support device.
Hensikten med oppfinnelsen er å opp-heve de ovenfor nevnte ulemper. The purpose of the invention is to eliminate the above-mentioned disadvantages.
Dette oppnås ifølge oppfinnelsen ved This is achieved according to the invention by
at polskoene før monteringen i maskinhuset har en i aksialretning utoverbuet form slik at de etter innmonteringen ligger fast presset såvel mot maskinhuset som mot støtteanordningen. that the pole shoes before installation in the machine housing have an outwardly curved shape in the axial direction so that after installation they lie firmly pressed both against the machine housing and against the support device.
Et utførelseseksempel på oppfinnelsen skal forklares nærmere under henvisning til tegningen. Fig. 1 viser et snitt gjennom en sykkeldynamo ifølge oppfinnelsen, i montert tilstand. Fig. 2 viser en sykkeldynamo ifølge fig. 1, hvor spolekjernen med polskoene er tatt ut av huset. An embodiment of the invention will be explained in more detail with reference to the drawing. Fig. 1 shows a section through a bicycle dynamo according to the invention, in the assembled state. Fig. 2 shows a bicycle dynamo according to fig. 1, where the coil core with the pole shoes has been removed from the housing.
I et hus 1 er anordnet en rotor 2 om-gitt av polskoene 3, som omsluttes av huset 1. Polskoene 3 er hver med en ende festet til en spolekjerne 4 som er forsynt med en spole 5. Den frie ende 8. av polskoene 3 støtter seg på utsiden av en skål 6 av ikke magnetisk materiale, som er forsynt med en ombøyet kant 7 og som fortrinnsvis har en større diameter enn rotoren 2. Polskoene 3 inntar derved den i fig. 2 viste hvelvede tønneform, slik at endene 8 i montert tilstand ifølge fig. 1 med en viss kraft ligger an mot kanten 7 på skålen 6 og midten av polskoene 3 trykkes mot inn-siden av huset 1. Spolekjernen 4 med polskoene 3 monteres etter at rotoren 2 er anordnet mellom polskoene 3 og skålen 6 anbringes så mellom endene 8, hvoretter det hele i akseretningen skyves inn i huset 1. Da den innvendige diameter av huset er mindre enn den største diameter av de hvelvede polsko 3, trykkes de innover slik at endene 8 kommer i anlegg mot skålkan-ten 7 og polskoene rettes ut helt eller delvis. In a housing 1, a rotor 2 is arranged surrounded by the pole shoes 3, which are enclosed by the housing 1. The pole shoes 3 are each attached with one end to a coil core 4 which is provided with a coil 5. The free end 8. of the pole shoes 3 rests on the outside of a bowl 6 of non-magnetic material, which is provided with a bent edge 7 and which preferably has a larger diameter than the rotor 2. The pole shoes 3 thereby occupy the one in fig. 2 showed a vaulted barrel shape, so that the ends 8 in the assembled state according to fig. 1 with a certain force rests against the edge 7 of the bowl 6 and the center of the pole shoes 3 is pressed against the inside of the housing 1. The coil core 4 with the pole shoes 3 is mounted after the rotor 2 is arranged between the pole shoes 3 and the bowl 6 is then placed between the ends 8 , after which the whole thing is pushed axially into the housing 1. As the internal diameter of the housing is smaller than the largest diameter of the domed pole shoes 3, they are pressed inwards so that the ends 8 come into contact with the bowl edge 7 and the pole shoes are fully straightened or partially.
