Disse koblinger har flere vigtige egenskaber. Disse egenskaber er: Stivhed, evolvente splinekoblinger, forkert justering, slid og udmattelsesbrud. For at forst\u00e5, hvordan disse egenskaber relaterer sig til splinekoblinger, kan du l\u00e6se denne artikel. Den vil give dig den n\u00f8dvendige viden til at bestemme, hvilken type kobling der bedst passer til dine behov. Husk p\u00e5, at splinekoblinger normalt er sf\u00e6riske i form, og de er lavet af st\u00e5l. En effektiv sideinterferenstilstand minimerer gearforskydning. N\u00e5r to splines er koblet uden splineforskydning, forskydes den maksimale tr\u00e6krodsp\u00e6nding til venstre med fem mm. En line\u00e6r variation i forspringet, som skyldes flere forbindelser langs splinekontaktens l\u00e6ngde, \u00f8ger den effektive frigang eller interferens med en given procentdel. Denne type forskydning er u\u00f8nsket til kobling af h\u00f8jhastighedsudstyr. Beregningen af \u200b\u200bstivheden af \u200b\u200ben splinekobling involverer m\u00e5ling af dens tandindgreb. I det f\u00f8lgende analyserer vi stivheden af \u200b\u200ben splinekobling med forskellige typer t\u00e6nder ved hj\u00e6lp af to forskellige metoder. Direkte inversion og blokvis inversion reducerer begge CPU-tiden til stivhedsberegning. De kr\u00e6ver dog evalueringsundermatricer. Her diskuterer vi forskellene mellem disse to metoder. For at bestemme centreringskraften skal den effektive trykvinkel v\u00e6re kendt. Ved hj\u00e6lp af den effektive trykvinkel beregnes centreringskraften baseret p\u00e5 de maksimale aksiale og radiale belastninger og opdaterede Dudley-forskydningsfaktorer. Centreringskraften er den maksimale aksiale kraft, der kan overf\u00f8res ved friktion. Adskillige publicerede fejljusteringsfaktorer er ogs\u00e5 inkluderet i beregningen. I denne artikel pr\u00e6senteres en ny metode, der tager h\u00f8jde for kameffekten i normalkraften. Fejl i en splinekobling p\u00e5 grund af slid og udmattelse bestemmes af den f\u00f8rste forekomst af tandslid og forskydning af akselen. Standarddesignmetoder tager ikke h\u00f8jde for slidskader og vurderer udmattelseslevetiden med store tiln\u00e6rmelser. Eksperimentelle unders\u00f8gelser er blevet udf\u00f8rt for at vurdere slid og udmattelsesskader i splinekoblinger. Testene blev udf\u00f8rt p\u00e5 en dedikeret testrigg og en speciel enhed forbundet til en standard udmattelsesmaskine. Arbejdsparametre s\u00e5som moment, forskydningsvinkel og aksial afstand er blevet varieret for at m\u00e5le udmattelsesskader. Overdimensionering er ogs\u00e5 blevet vurderet.

<\/p>\nInvolvente splines<\/h2>\n
Evolvente noter bruges ofte i gearkasser. Disse noter overf\u00f8rer et h\u00f8jt drejningsmoment og er bedre i stand til at fordele belastningen mellem flere t\u00e6nder i hele koblingens omkreds. Evolventprofilen og stigningsfejlene er relateret til afstanden mellem nott\u00e6nder og kilespor. Til koblingsapplikationer bruger industripraksis noter med 25 til halvtreds procent af nott\u00e6nderne indgrebet. Denne belastningsfordeling er mere ensartet end for konventionelle enkeltkilekoblinger.
For at bestemme det optimale tandindgreb for en involveret splinekobling brugte Xiangzhen Xue og kolleger en computermodel til at simulere den belastning, der p\u00e5f\u00f8res splines. Resultaterne fra denne unders\u00f8gelse viste, at en \"tilladelig\" Ruiz-parameter b\u00f8r anvendes ved kobling. Ved at forudsige m\u00e6ngden af \u200b\u200bslid p\u00e5 en kronet spline kunne forskerne n\u00f8jagtigt forudsige, hvor meget skade komponenterne vil lide under koblingsprocessen.
Der er flere m\u00e5der at bestemme den optimale trykvinkel for en evolvent spline. Evolvente splines m\u00e5les almindeligvis ved hj\u00e6lp af en trykvinkel p\u00e5 30 grader. Ligesom tandhjul testes evolvente splines typisk ved at m\u00e5le dem over stifter. Dette involverer at inds\u00e6tte tr\u00e5de i en specifik st\u00f8rrelse mellem tandhjulst\u00e6nderne og m\u00e5le afstanden mellem dem. Denne metode kan afg\u00f8re, om tandhjulet har en korrekt tandprofil.
Splinesystemet vist i figur 1 illustrerer en vibrationsmodel. Denne simulering giver brugeren mulighed for at forst\u00e5, hvordan evolvente splines bruges i kobling. Vibrationsmodellen viser fire koncentrerede masseblokke, der repr\u00e6senterer drivmotoren, den interne spline og lasten. Det er vigtigt at bem\u00e6rke, at den indgribende deformationsfunktion repr\u00e6senterer de kr\u00e6fter, der virker p\u00e5 disse tre komponenter.![\"splineaksel\"](\"https:\/\/img.hzpt.com\/img\/spline_shaft\/C_splineshaft_4.webp\")
<\/p>\nKoblingens stivhed<\/h2>\n
Den analytiske model for splinekoblinger er udledt i andet afsnit. I tredje afsnit forklares beregningsprocessen i detaljer. Vi validerer derefter denne model i forhold til FE-metoden. Endelig diskuterer vi indflydelsen af \u200b\u200bstivhedens ikke-linearitet p\u00e5 rotordynamikken. Endelig diskuterer vi fordele og ulemper ved hver metode. Vi pr\u00e6senterer en simpel, men effektiv metode til at estimere den laterale stivhed af splinekoblinger.
Den numeriske beregning af splinekoblingen er baseret p\u00e5 den semi-analytiske spline-belastningsfordelingsmodel. Denne metode involverer raffinerede kontaktgitre og opdatering af compliance-matricen ved hver iteration. Derfor bruger den betydelig beregningstid. Desuden er det vanskeligt at anvende denne metode til dynamisk analyse af en rotor. Denne metode har sine egne begr\u00e6nsninger og b\u00f8r kun anvendes, n\u00e5r splinekoblingen er fuldt unders\u00f8gt.
Indgrebskraften er den kraft, der genereres af en forkert justeret splinekobling. Den er relateret til splinetykkelsen og rotorens transmitterende drejningsmoment. Indgrebskraften er ogs\u00e5 relateret til den dynamiske vibrationsforskydning. Resultatet fra indgrebskraftanalysen er vist i figur 7, 8 og 9.
Analysen pr\u00e6senteret i denne artikel har til form\u00e5l at unders\u00f8ge stivheden af \u200b\u200bspline-koblinger med en sk\u00e6vt justeret spline. Selvom resultaterne fra tidligere unders\u00f8gelser var n\u00f8jagtige, forblev nogle problemer ul\u00f8ste. For eksempel kan sk\u00e6v justering af spline for\u00e5rsage kontaktskader. Form\u00e5let med denne artikel er at unders\u00f8ge de problemer, der er forbundet med sk\u00e6vt justerede spline-koblinger og foresl\u00e5 en analytisk tilgang til estimering af kontakttrykket i en spline-forbindelse. Vi sammenligner ogs\u00e5 vores resultater med dem, der opn\u00e5s ved rene numeriske tilgange.<\/p>\nForskydning<\/h2>\n
I denne nye metode kan stivheden langs splineforbindelsen integreres for at opn\u00e5 en global stivhed, der kan anvendes til torsionsvibrationsanalyse. Lejernes stivhed kan ogs\u00e5 beregnes ved givne niveauer af forskydning, hvilket muligg\u00f8r en n\u00f8jagtig estimering af lejernes dimensioner. Det tilr\u00e5des at kontrollere lejernes stivhed til enhver tid for at sikre, at de er korrekt dimensioneret og justeret.
En fejljustering i en splinekobling kan resultere i slid eller endda svigt. Dette skyldes en forkert justeret stigningsprofil. Dette problem overses ofte, da t\u00e6nderne er i kontakt gennem hele den evolvente profil. Dette for\u00e5rsager, at belastningen ikke fordeles j\u00e6vnt langs kontaktlinjen. Derfor er det vigtigt at overveje effekten af \u200b\u200bfejljustering p\u00e5 kontaktkraften p\u00e5 splinekoblingens t\u00e6nder.
Centrum af han-spline i figur 2 er overlejret hun-spline. Indgrebsafstandene for justering er ogs\u00e5 identiske. Derfor vil indgrebskraftkurverne \u00e6ndre sig i henhold til den dynamiske vibrationsforskydning. Det er n\u00f8dvendigt at kende parametrene for en splinekobling, f\u00f8r den implementeres. I denne artikel pr\u00e6senteres modellen for ujustering for splinekoblinger og de relaterede parametre.
Ved hj\u00e6lp af en hjemmelavet testrigg til splinekoblinger unders\u00f8ges virkningerne af forkert justering p\u00e5 en splinekobling. I mods\u00e6tning til den typiske splinekobling for\u00e5rsager forkert justering i en splinekobling gnavslid p\u00e5 en specifik position p\u00e5 tandoverfladen. Dette er en f\u00f8rende \u00e5rsag til svigt i disse typer koblinger.![\"splineaksel\"](\"https:\/\/img.hzpt.com\/img\/spline_shaft\/B_splineshaft_4.webp\")
<\/p>\nSlid- og udmattelsessvigt<\/h2>\n
Under udmattelse og slitage finder mekanisk glidning sted mellem de udvendige og indvendige noter, hvilket resulterer i katastrofale svigt. Manglen p\u00e5 litteratur om slid og udmattelse af notkoblinger i flymotorer kan skyldes manglende data om koblingens anvendelse. Slid og udmattelsesbrud i noter afh\u00e6nger af en r\u00e6kke faktorer, herunder materialepar, geometri og sm\u00f8reforhold.
Analysen af \u200b\u200bsplinekoblinger viser, at overdimensionering er almindeligt og f\u00f8rer til forskellige skader i systemet. Nogle af de st\u00f8rste skader er slid, gnaven, korrosion og tandtr\u00e6thed. St\u00f8jproblemer er ogs\u00e5 blevet observeret i industrielle milj\u00f8er. Det er dog vanskeligt at evaluere kontaktadf\u00e6rden af \u200b\u200bsplinekoblinger, og numeriske simuleringer h\u00e6mmes ofte af brugen af \u200b\u200bspecifikke koder og gr\u00e6nseelementmetoden.
Fejlen i en splinegearkobling var for\u00e5rsaget af udmattelse, og bruddet startede ved kilegangens nederste hj\u00f8rneradius. Kilegangen og splines var blevet overbelastet ud over deres flydegr\u00e6nse, og der blev observeret betydelig flydeevne i splinegearets t\u00e6nder. En brudring af ikke-standard legeret st\u00e5l udviste en skarp hj\u00f8rneradius, hvilket var en betydelig sp\u00e6ndingsfor\u00f8ger.
Adskillige komponenter blev unders\u00f8gt for at bestemme deres levetid. Disse komponenter omfatter splineakslen, t\u00e6tningsbolten og grafitringen. Hver af disse komponenter har sit eget s\u00e6t designparametre. Der er dog ligheder i fordelingen af \u200b\u200bdisse komponenter. Slid- og udmattelsessvigt i splinekoblinger kan tilskrives en kombination af de tre faktorer. En fejltilstand defineres ofte som en ikke-line\u00e6r fordeling af sp\u00e6ndinger og t\u00f8jninger.<\/p>\n![\"China](\"https:\/\/img.hzpt.com\/img\/spline_shaft\/spline_shaft_l1.webp\")
