Den best\u00e5r af to dele \u2013 en kobling og en kobling. Begge dele har t\u00e6nder, der griber ind og overf\u00f8rer belastninger. Splinekoblinger er dog typisk overdimensionerede, hvilket g\u00f8r dem modtagelige for tr\u00e6thed og statisk adf\u00e6rd. Slidf\u00e6nomener kan ogs\u00e5 for\u00e5rsage, at koblingen svigter. Af denne grund er korrekt design af splinekoblinger afg\u00f8rende for at opn\u00e5 optimal ydeevne. Splinekoblinger bliver mere og mere popul\u00e6re i luftfartsindustrien, men de fungerer i en lidt sk\u00e6vt justeret tilstand, hvilket for\u00e5rsager b\u00e5de vibrationer og beskadigelse af kontaktfladerne. For at l\u00f8se dette problem tilbyder denne artikel analytiske tilgange til estimering af kontakttrykkene i en splinekobling. Specifikt sammenligner denne artikel analytiske tilgange med rene numeriske tilgange for at demonstrere fordelene ved en analytisk tilgang. Spline-koblingsmodellen 20 oprettes af et produktmodel-softwareprogram 10. Softwaren validerer spline-koblingsmodellen i forhold til en vidensbase af konfigurationsafh\u00e6ngige specifikationsbegr\u00e6nsninger og relationer. Denne rapport sendes derefter til ANSYS stressanalysatorprogrammet. Den viser spline-koblingsmodellen 20's geometriske konfigurationer og specifikationsv\u00e6rdier for hver funktion. Spline-koblingsmodellen 20 genskabes automatisk, hver gang konfigurations- eller ydeevnespecifikationerne for spline-koblingsmodellen 20 \u00e6ndres. En analyse af en spline-koblingsmodel best\u00e5r i at indtaste dens konfigurations- og ydeevnespecifikationer. Disse specifikationer kan genereres fra et andet computerprogram. Produktmodel-softwareprogrammet 10 bruger derefter sin interne vidensbase af konfigurationsafh\u00e6ngige specifikationsrelationer og begr\u00e6nsninger til at oprette en gyldig tredimensionel parametrisk model 20. Denne model indeholder information, der beskriver antallet og typerne af spline-t\u00e6nder 32, snaps 34 og skulder 36. En unders\u00f8gelse havde til form\u00e5l at unders\u00f8ge positionen af \u200b\u200bden resulterende kontaktkraft i en splinekobling, der griber ind i t\u00e6nder under et konstant moment og roterende forskydning. Unders\u00f8gelsen anvendte numeriske metoder baseret p\u00e5 Finite Element Method (FEM)-modeller. Den producerede numeriske resultater for nominelle forhold og parallel forskydningsforskydning. Unders\u00f8gelsen betragtede to niveauer af forskydning \u2013 0,02 mm og 0,08 mm \u2013 med forskellige belastningsniveauer.

<\/p>\nModellering af en spline-kobling<\/h2>\n
For at modellere en spline-kobling skal du f\u00f8rst oprette en vidensbase for spline-koblingen. Vidensbasen indeholder et stort antal mulige specifikationsv\u00e6rdier, som er relateret til hinanden. Hvis du \u00e6ndrer \u00e9n specifikation, kan det f\u00f8re til en advarsel om overtr\u00e6delse af en anden. For at g\u00f8re designet gyldigt skal du oprette en spline-koblingsmodel, der opfylder de angivne specifikationsv\u00e6rdier.
N\u00e5r du har modelleret geometrien, skal du indtaste kontakttrykkene for de to splinekoblinger. Derefter skal du bestemme positionen af \u200b\u200bsplinekoblingens stigningscirkel. I figur 2 er midten af \u200b\u200bhankoblingen overlejret midten af \u200b\u200bhunsplinen. Derefter skal du s\u00f8rge for, at justeringsindgrebsafstanden for de to splines er den samme.
N\u00e5r du har de data, du skal bruge til at oprette en spline-koblingsmodel, kan du begynde med at indtaste specifikationerne for gr\u00e6nsefladedesignet. N\u00e5r du har disse data, skal du v\u00e6lge, om du vil optimere den interne spline eller den eksterne spline. Du skal ogs\u00e5 angive tandfriktionskoefficienten, som bruges til at bestemme sp\u00e6ndingerne i spline-koblingsmodellen 20. Du skal ogs\u00e5 indtaste pilotfrigangen, som er frigangen mellem spidsen 186 af en tand 32 p\u00e5 den ene spline og funktionen p\u00e5 den modst\u00e5ende spline.
N\u00e5r du har indtastet de \u00f8nskede specifikationer for den eksterne spline, kan du indtaste parametrene for den interne spline. For eksempel kan du indtaste den ydre diametergr\u00e6nse 154 for det store snap 54 og det lille snap 56 for den interne spline. V\u00e6rdierne for disse parametre vises i farvekodede bokse p\u00e5 Spline Inputs and Configuration GUI-sk\u00e6rmen 80. N\u00e5r parametrene er indtastet, vil du blive pr\u00e6senteret for en geometrisk repr\u00e6sentation af spline-koblingsmodellen 20.<\/p>\nOprettelse af en splinekoblingsmodel 20<\/h2>\n
Splinekoblingsmodellen 20 kan konfigureres ved hj\u00e6lp af produktmodelsoftwareprogrammet 10. En bruger specificerer den aksiale l\u00e6ngde af splinestakken, som kan v\u00e6re nul eller en fast l\u00e6ngde. Brugeren indtaster ogs\u00e5 en radial modflade 148, hvis der er en, og v\u00e6lger en specifikationsv\u00e6rdi for pilotfrigang p\u00e5 14,5 grader eller 30 grader.
En bruger kan derefter bruge musen 110 til at \u00e6ndre spline-koblingsmodellen 20. Vidensbasen for spline-kobling indeholder et stort antal mulige specifikationsv\u00e6rdier og spline-koblingsdesignreglen. Hvis brugeren fors\u00f8ger at \u00e6ndre en spline-koblingsmodel, viser modellen en advarsel om en overtr\u00e6delse af en anden specifikation. I nogle tilf\u00e6lde kan \u00e6ndringen ugyldigg\u00f8re designet.
I splinekoblingsmodellen 20 indtaster brugeren yderligere specifikationer for ydeevnekrav. Brugeren v\u00e6lger de steder, hvor det maksimale moment overf\u00f8res for de interne og eksterne splines 38 og 40. Placeringen for den maksimale momentoverf\u00f8rsel bestemmes af hardwarens fastg\u00f8relseskonfiguration til akslerne. N\u00e5r dette er valgt, kan brugeren klikke p\u00e5 \"N\u00e6ste\" for at gemme modellen. Der vises et eksempel p\u00e5 splinekoblingsmodellen 20.
Modellen 20 er en repr\u00e6sentation af en spline-kobling. Spline-specifikationerne indtastes i den r\u00e6kkef\u00f8lge og placering, der er angivet p\u00e5 GUI-sk\u00e6rmen til spline-koblingsmodellen 20. N\u00e5r spline-koblingsspecifikationerne er indtastet, vil produktmodel-softwareprogrammet 10 inkorporere dem i spline-koblingsmodellen 20. Dette er det sidste trin i oprettelsen af \u200b\u200bspline-koblingsmodellen.![\"splineaksel\"](\"https:\/\/img.hzpt.com\/img\/spline_shaft\/C_splineshaft_2.webp\")
<\/p>\nAnalyse af en spline-koblingsmodel 20<\/h2>\n
N\u00e5r du analyserer en spline-kobling, vil softwareprogrammet 10 inkludere standardv\u00e6rdier for forskellige specifikationer. Spline-koblingsmodellen 20 omfatter en intern spline 38 og en ekstern spline 40. Hver af splines inkluderer sit eget s\u00e6t parametre, s\u00e5som dens dybde, bredde, l\u00e6ngde og radius. Den eksterne spline 40 vil ogs\u00e5 indeholde sit eget s\u00e6t parametre, s\u00e5som dens orientering.
N\u00e5r disse parametre er valgt, udf\u00f8rer softwareprogrammet forskellige analyser p\u00e5 splinekoblingsmodellen 20. Softwareprogrammet 10 beregner de nominelle og maksimale tandlejesp\u00e6ndinger og udmattelseslevetiden for en splinekobling. Det bestemmer ogs\u00e5 forskellen i torsionsvikling mellem en intern og en ekstern spline. Outputfilen fra analysen vil v\u00e6re en rapportfil, der indeholder modelkonfigurations- og specifikationsdata. Outputfilen kan ogs\u00e5 bruges af andre computerprogrammer til yderligere analyse.
N\u00e5r disse parametre er indstillet, indtaster brugeren designkriterierne for splinekoblingsmodellen 20. I dette trin specificerer brugeren placeringen af \u200b\u200bmaksimal momentoverf\u00f8rsel for b\u00e5de den eksterne og interne spline 38. Placeringen af \u200b\u200bmaksimal momentoverf\u00f8rsel afh\u00e6nger af konfigurationen af \u200b\u200bden hardware, der er fastgjort til akslerne. Brugeren kan indtaste op til fire forskellige ydelseskravspecifikationer for hver spline.
Resultaterne af analysen viser, at der er to faser af splinekobling. Den f\u00f8rste fase viser en stor stigning i sp\u00e6nding og vibration. Den anden fase viser et fald i b\u00e5de sp\u00e6ndings- og vibrationsniveauer. Den tredje fase viser en konstant indgrebskraft mellem 300 N og 320 N. Denne adf\u00e6rd forts\u00e6tter i en l\u00e6ngere periode, indtil den sidste fase griber ind i overfladen.![\"splineaksel\"](\"https:\/\/img.hzpt.com\/img\/spline_shaft\/B_splineshaft_2.webp\")
<\/p>\nForkert justering af en splinekobling<\/h2>\n
Resultaterne viste, at den forkerte justering mellem splines og rotorer for\u00e5rsager en \u00e6ndring i indgrebskraften i spline-rotor-koblingssystemet. Dens dynamik styres af splines' indgrebskraft. Indgrebskraften i en forkert justeret spline-kobling er relateret til rotor-spline-koblingssystemets parametre, det transmitterende drejningsmoment og den dynamiske vibrationsforskydning.
Trods manglen p\u00e5 pr\u00e6cise m\u00e5linger er fejljustering af splines et almindeligt problem. Dette problem forv\u00e6rres af, at splines normalt har sl\u00f8r. Dette sl\u00f8r er resultatet af den fejljusterede spline. Forfatterne analyserede adskillige splines med varierende stigningsdiametre og l\u00e6ngde\/diameterforhold.
En splinekobling er et todimensionelt mekanisk system med positivt sl\u00f8r. Splinekoblingen best\u00e5r af et nav og en aksel og har spids-til-rod-frigange, der er st\u00f8rre end sl\u00f8ret. Et formfrigang er tilstr\u00e6kkeligt til at forhindre kontakt mellem spids og rod-filet. Drejningsmomentet p\u00e5 splines overf\u00f8res via friktion.
N\u00e5r en splinekobling er forkert justeret, genereres en momentforsp\u00e6ndt trykkraft. I en s\u00e5dan situation kan kraften overstige momentet, hvilket f\u00e5r komponenten til at miste sin justering. Tovejsoverf\u00f8rslen af \u200b\u200bmoment og tryk modelleres analytisk i denne unders\u00f8gelse. Den analytiske tilgang giver l\u00f8sninger, der kan integreres i designprocessen. S\u00e5 n\u00e6ste gang du st\u00e5r over for et problem med en forkert justeret splinekobling, skal du s\u00f8rge for at bruge en analytisk tilgang!
I denne unders\u00f8gelse analyseres splinekoblingen under nominelle forhold uden parallelforskydning. De opn\u00e5ede stivhedsv\u00e6rdier er den procentvise forskel mellem den nominelle stigningsdiameter og belastningsp\u00e5f\u00f8ringsdiameteren. Desuden er den maksimale procentvise forskel i den m\u00e5lte stigningsdiameter 1,60% under et moment p\u00e5 5000 N*m. Den anden parameter, stigningsvinklen, tages i betragtning i beregningen.<\/p>\n![\"China](\"https:\/\/img.hzpt.com\/img\/spline_shaft\/spline_shaft_l1.webp\")
