Description
Lamellert, av blikk bestående legeme, særlig for elektriske maskiner. Lamellar body made of tin, especially for electrical machines.
Lamellerte legemer, bestående av blikk, benyttes særlig for elektriske maskiner (sjiktkransrotor, statorblikkpakke, blikk-polerj. I en lamellert rotor overfores tangensialkraften ved trykk ("Lochleibung") og friksjon, hos statoren vanligvis bare ved friksjon. Ved statorblikkpakken vil det som folge av blikk-pakkens termiske ekspansjon overfor det svalere hus oppstå et trykk, som kan fore til bolgedannelse i blikkpakken. Som mot-forholdsregel virker strekkforspenning av blikkpakken, men den-ne forspenning oppnås vanligvis bare ved friksjon. I det sveit-siske patentskrift 345 688 er det beskrevet en fremgangsmåte for fremstilling av en blikkpakke, som gjelder blikkpakkekle-bing. Slik klebing på monteringsstedet er forbundet med for-holdsvis store omkostninger. Opprommingen av hullene for boltene til sikring av kraftoverforingen ved trykk er likeledes uoko-nomisk. Laminated bodies, consisting of sheet metal, are used in particular for electrical machines (layer crown rotor, stator tin pack, tin polisherj. In a laminated rotor, the tangential force is transmitted by pressure ("Lochleibung") and friction, in the stator usually only by friction. With the stator tin pack, the following will from the thermal expansion of the tin pack against the cooler housing, a pressure arises, which can lead to the formation of waves in the tin pack. As a countermeasure, tensile prestressing of the tin pack works, but this prestressing is usually only achieved by friction. In the Swiss patent document 345 688 a method for the production of a tin package is described, which applies to tin package gluing. Such gluing at the assembly site is associated with relatively large costs. The reaming of the holes for the bolts to secure the power transmission by pressure is likewise uneconomical.
Oppfinnelsen går spesielt ut på å tilveiebringe et lamellert legeme, bestående av blikk, spesielt for elektriske maskiner, hvilket legeme kan fremstilles okonomisk og med enkle midler og er i stand til å overfore tangensialkraften uten kostbare virke-midler, som f.eks. bolter i opprommede huller. The invention is particularly concerned with providing a laminated body, consisting of sheet metal, especially for electrical machines, which body can be produced economically and with simple means and is capable of transmitting the tangential force without expensive means, such as e.g. bolts in reamed holes.
Nevnte oppgave loses ifolge oppfinnelsen ved at i det minste enkelte blikkplater er forsynt med formtilpassede elementer og/ eller hjelpemidler som oker friksjonskoeffisienten av minst en av blikkplatenes overflater. According to the invention, said task is solved by at least some tin plates being provided with form-fitting elements and/or aids which increase the friction coefficient of at least one of the tin plates' surfaces.
Fordelen ved oppfinnelsen består især i at de formtilpassede elementer og/eller hjelpemidlene som oker friksjonskoeffisienten av minst en av blikkplatenes overflater vesentlig bedrer over foringen av tangensialkraften, slik at man f.eks. kan unnvære oppromming av bolthuller ved sjiktkranser og blikkpoler hhv. klebing ved blikkpakker. The advantage of the invention consists in particular in that the shaped elements and/or aids which increase the friction coefficient of at least one of the sheet metal surfaces substantially improve the tangential force over the lining, so that e.g. can dispense with reaming of bolt holes at layer crowns and tin poles or gluing of tin packages.
Ved en utforelsesform består de formtilpassede elementer av partikler som fortrinnsvis er inneholdt i en klebestoffemulsjon. Disse partikler, som består av et hardt materiale, f. In one embodiment, the shaped elements consist of particles which are preferably contained in an adhesive emulsion. These particles, which consist of a hard material, e.g.
eks. stål eller sand, og er inneholdt i en klebestoffemulsjon, f.eks. i epoksyd- eller polyesterharpiks, vil presses inn i overflaten ved sammenpressing av blikkplatene, f.eks. ved til-trekking av boltene, hvorved overforingen av tangensialkraften bedres. e.g. steel or sand, and is contained in an adhesive emulsion, e.g. in epoxy or polyester resin, will be pressed into the surface by compressing the tin plates, e.g. by tightening the bolts, whereby the transfer of the tangential force is improved.
Ved en annen utformning består de formtilpassede elementer av forhoyninger hhv. fordypninger på blikkplatenes overflate. Disse forskjelligartet utformede forhoyninger hhv. fordypninger griper i hverandre i de enkelte blikk-lag og sikrer den onskede innbyrdes stilling. De formtilpassede elementer kan også bestå av utpressede forhoyninger i kanten av bolthullet eller av delvis utstansede blikkpartier, som rager frem av blikkoverflaten, f.eks. tunger, takker og strimler. Ved de delvis utstansede deler som er boyd frem av blikkoverflaten, skjer kraftoverfbringen over snittflatene, hvorved strekk- og trykkrefter kan overfores. Det er fordelaktig at blikkplatene vekselvis er forsynt med de formtilpassede elementer og åpninger som svarer til disse elementer. Man kan f.eks. utelate hver annen tunge i sjiktretning og vekselvis også i lengderetning og således oppnå at en noyak-tig gjensidig tilpasning av tungene bare er nodvendig i en ret-ning. In another design, the form-fitting elements consist of elevations or depressions on the surface of the tin plates. These differently designed elevations or recesses interlock in the individual glazing layers and ensure the desired mutual position. The form-fitting elements can also consist of extruded elevations at the edge of the bolt hole or of partially punched-out tin sections, which protrude from the tin surface, e.g. tongues, ridges and strips. In the case of the partially punched-out parts that are projected from the tin surface, the force is transferred over the cut surfaces, whereby tensile and compressive forces can be transferred. It is advantageous that the tin plates are alternately provided with the form-fitting elements and openings that correspond to these elements. One can e.g. leave out every other tongue in the layer direction and alternately also in the longitudinal direction and thus achieve that a precise mutual adaptation of the tongues is only necessary in one direction.
Ved ytterligere en utformning er blikkplatene kjemisk eller mekanisk oppruet på minst en av sine to overflater. Det benyttes f.eks. ensidig eller tosidig etsede blikkplater eller blikkplater som er oppruet ved valsing eller pressing. In a further design, the tin plates are chemically or mechanically roughened on at least one of their two surfaces. It is used e.g. single-sided or double-sided etched tinplate or tinplate which has been roughened by rolling or pressing.
I tegningen er noen utforelseseksempler av oppfinnelsens gjenstand vist i forenklet gjengivelse. Fig. 1 viser et forste utforelseseksempel med innpressede partikler i snitt. Fig. 2 viser et andre utforelseseksempel med utpressede forhoyninger . Fig. 3 viser et tredje utforelseseksempel med utpressede forhoyninger i kanten av bolthullet. Fig. 4 viser et fjerde utforelseseksempel med utstansede tunger, sett ovenfra. In the drawing, some exemplary embodiments of the subject matter of the invention are shown in a simplified representation. Fig. 1 shows a first embodiment example with pressed-in particles in section. Fig. 2 shows a second design example with extruded elevations. Fig. 3 shows a third design example with extruded elevations at the edge of the bolt hole. Fig. 4 shows a fourth embodiment example with punched out tongues, seen from above.
Fig. 5 er et snitt etter linjen V-V i fig. 4.Fig. 5 is a section along the line V-V in fig. 4.
Fig. 6 viser et femte utforelseseksempel med utstansede strimler, sett ovenfra. Fig. 6 shows a fifth embodiment example with punched strips, seen from above.
Fig.' 7 er et snitt etter linjen VII-VII i fig. 6.Fig.' 7 is a section along the line VII-VII in fig. 6.
Fig. 8 viser et sjette utforelseseksempel med utstansede strimler og tilsvarende åpninger. Fig. 8 shows a sixth embodiment example with punched strips and corresponding openings.
I samtlige figurer betegner 1 blikkplater. Partiklene i fig. 1 er betegnet med 2 og forhoyningene i fig. 2 med 3. I fig. 3 betegner 4 utpressede forhoyninger i kanten av bolthullet, 5 en bolt, 6 muttere og 7 underlag. I figurene 4 og 5 er tungene betegnet med 8 og i fig. 4 betegner 8' utstansede skillelinjer for tungen 8. I figurene 6-8 er strimlene betegnet med 9 og i fig. 6 betegner 9' utstansede skillelinjer for strimmelen 9. I fig. 8 er en åpning betegnet med 10. In all figures, 1 denotes tin plates. The particles in fig. 1 is denoted by 2 and the elevations in fig. 2 with 3. In fig. 3 denotes 4 extruded elevations at the edge of the bolt hole, 5 a bolt, 6 nuts and 7 support. In figures 4 and 5, the tongues are denoted by 8 and in fig. 4 denotes 8' punched dividing lines for the tongue 8. In figures 6-8 the strips are denoted by 9 and in fig. 6 designates 9' punched dividing lines for the strip 9. In fig. 8 is an opening designated by 10.
Det forste utforelseseksempel ifolge fig. 1 viser blikkplatene 1 i snitt med harde partikler eller korn 2, som er presset inn i blikkplatenes overflater. Partiklene 2 kan også ha andre former og må ikke være. så regelmessig fordelt som vist i tegningen. Forhøyningene 3 i fig. 2 griper inn i fordypningene i nærlig-gende blikkplater 1 og sikrer den innbyrdes stilling av blikkplatene 1 i flateretningen. Fig. 3 viser bolten 5 med sine muttere 6 og underlag 7. Oppromming av bolthullet er bortfalt, fordi de vorteformet utpressede forhoyninger 4 sikrer tilstrek-kelig kraftoverfbring i blikkplatenes 1 flateretning. Tungene 8 som vist i fig. 4 og 5 er stanset ut etter skillelinjene"8' og bbyd opp av blikkplatenes 1 overflate. En annen utforelsesform er vist i fig. 6 og 7. Strimlene 9 er stanset ut og bbyd som angitt ved skillelinjene 9'. Ved de sistnevnte utforelseseksempler skjer kraftoverfbringen via snittflatene. Fig. 8 viser en konstruktiv lbsning, som omfatter strimler 9 som vist i fig. 6 og 7. Disse strimler 9 er imidlertid utelatt vekselvis ved de enkelte blikkplater 1. I fig. 8 er fbrste og tredje plate 1 forsynt med hver sin strimmel 9, den andre blikkplate har åp-ningen 10, hvor nedre strimmel 9 rager inn. The first embodiment according to fig. 1 shows the tin plates 1 in section with hard particles or grains 2, which are pressed into the surfaces of the tin plates. The particles 2 can also have other shapes and do not have to be. as regularly spaced as shown in the drawing. The elevations 3 in fig. 2 engages in the depressions in adjacent tin plates 1 and ensures the mutual position of the tin plates 1 in the surface direction. Fig. 3 shows the bolt 5 with its nuts 6 and base 7. Reaming of the bolt hole is omitted, because the wart-shaped extruded elevations 4 ensure sufficient power transmission in the sheet direction of the tin plates 1. The tongues 8 as shown in fig. 4 and 5 are punched out along the dividing lines "8' and bent up from the surface of the tin plates 1. Another embodiment is shown in Fig. 6 and 7. The strips 9 are punched out and bent as indicated by the dividing lines 9'. In the latter examples of embodiment, the power transmission via the cut surfaces. Fig. 8 shows a constructive solution, which includes strips 9 as shown in Fig. 6 and 7. However, these strips 9 are omitted alternately at the individual tin plates 1. In Fig. 8, the first and third plate 1 are provided with each with its own strip 9, the other tin plate has the opening 10, where the lower strip 9 protrudes.
Oppfinnelsens gjenstand er selvsagt ikke begrenset til det som er vist i' tegningen. Således kan en eller begge overflater av iallfall enkelte blikkplater 1 opprues mekanisk eller kjemisk. De formtilpassede elementer 3,4,8,9 kan ha andre former enn The object of the invention is of course not limited to what is shown in the drawing. Thus, one or both surfaces of at least some tin plates 1 can be mechanically or chemically roughened. The form-fitting elements 3,4,8,9 can have other forms than
de gjengitte og det kan benyttes andre former for formtilpassede elementer. those reproduced and other forms of form-fitting elements can be used.
