Vzh\u013eadom na geometriu spline spojenia sa na v\u00fdpo\u010det tuhosti pou\u017e\u00edva semianalytick\u00fd model. Tento model je zjednodu\u0161enou formou klasick\u00e9ho spline spojenia s podmaticami definuj\u00facimi tvar a tuhos\u0165 spoja. Ke\u010f\u017ee kon\u0161truk\u010dn\u00e1 v\u00f4\u013ea je zn\u00e1ma hodnota, tuhos\u0165 syst\u00e9mu spline spojenia je mo\u017en\u00e9 analyzova\u0165 pomocou rovnak\u00e9ho vzorca.

Vplyv nespr\u00e1vneho zarovnania dr\u00e1\u017eok na spojenie rotor-dr\u00e1\u017eka<\/h2>\n

V tejto \u0161t\u00fadii sa sk\u00fama vplyv nespr\u00e1vneho zarovnania dr\u00e1\u017eok v spojen\u00ed rotor-dr\u00e1\u017eka. Analyzuje sa hranica stability a mechanizmus nestability rotora. Zistili sme, \u017ee z\u00e1berov\u00e1 sila nespr\u00e1vne zarovnan\u00e9ho dr\u00e1\u017ekov\u00e9ho spojenia sa neline\u00e1rne zvy\u0161uje s hr\u00fabkou dr\u00e1\u017eky. V\u00fdsledky ukazuj\u00fa, \u017ee nespr\u00e1vne zarovnanie je zodpovedn\u00e9 za nestabilitu syst\u00e9mu spojenia rotor-dr\u00e1\u017eka.
Z\u00e1mern\u00e9 vych\u00fdlenie dr\u00e1\u017eok sa zav\u00e1dza na dosiahnutie presahu a nulovej v\u00f4le. To vedie k nerovnomern\u00e9mu rozlo\u017eeniu za\u0165a\u017eenia medzi zubami dr\u00e1\u017eok. \u010eal\u0161ie vych\u00fdlenie dr\u00e1\u017eok o 50 \u03bcm m\u00f4\u017ee vies\u0165 k zlyhaniu spoja rotor-dr\u00e1\u017eka. Za tejto podmienky sa maxim\u00e1lne \u0165ahov\u00e9 nap\u00e4tie v kore\u0148ovej \u010dasti posunulo do\u013eava.
Kladn\u00e9 vych\u00fdlenie dr\u00e1\u017eok zvy\u0161uje vych\u00fdlenie z\u00e1beru ozuben\u00fdch kolies. Naopak, z\u00e1porn\u00e9 vych\u00fdlenie dr\u00e1\u017eok nem\u00e1 \u017eiadny vplyv. Pravoto\u010div\u00e9 vych\u00fdlenie dr\u00e1\u017eok je opa\u010dn\u00e9 ako skrutkovicov\u00e9. Najvy\u0161\u0161ia kontaktn\u00e1 plocha sa pos\u00fava zo stredu na \u013eav\u00fa stranu. V oboch pr\u00edpadoch je z\u00e1ber ozuben\u00fdch kolies vych\u00fdlen\u00fd v d\u00f4sledku vych\u00fdlenia a naklonenia ozuben\u00e9ho kolesa pod za\u0165a\u017een\u00edm.
T\u00e1to zmena povrchu zuba sa meria ako zmena v\u00f4le v prie\u010dnej rovine. Hodnoty radi\u00e1lnej a axi\u00e1lnej v\u00f4le s\u00fa rovnak\u00e9, zatia\u013e \u010do rozdiel medzi nimi je men\u0161\u00ed. Okrem trecej sily je rovnak\u00e1 aj axi\u00e1lna v\u00f4\u013ea dr\u00e1\u017eok, \u010do zvy\u0161uje nes\u00faosos\u0165 z\u00e1beru ozuben\u00fdch kolies. Rovnak\u00fd postup sa teda d\u00e1 pou\u017ei\u0165 na ur\u010denie trecej sily spojky rotor-dr\u00e1\u017eka.
Nes\u00faosos\u0165 z\u00e1beru ozuben\u00fdch kolies ovplyv\u0148uje v\u00fdkon spojky dr\u00e1\u017eka-rotor. T\u00e1to nes\u00faosos\u0165 men\u00ed rozlo\u017eenie z\u00e1beru ozuben\u00fdch kolies a men\u00ed kontaktn\u00e9 a ohybov\u00e9 nap\u00e4tia. Preto je nevyhnutn\u00e9 pochopi\u0165 \u00fa\u010dinky nes\u00faososti v dr\u00e1\u017ekov\u00fdch spojk\u00e1ch. Hong a kol. sk\u00famali pomocou zjednodu\u0161en\u00e9ho syst\u00e9mu \u0161pir\u00e1lov\u00fdch ozuben\u00fdch kolies rozlo\u017eenie za\u0165a\u017eenia pozd\u013a\u017e zubov\u00e9ho rozhrania dr\u00e1\u017eky. T\u00e1to nes\u00faosos\u0165 sp\u00f4sobila zmenu kontaktn\u00e9ho vzoru bokov. Nes\u00faos\u00e9 zuby vykazovali pri za\u0165a\u017een\u00ed priehyb a vyv\u00edjali klopn\u00fd moment na ozubenom kolese.
Vplyv nespr\u00e1vneho zarovnania dr\u00e1\u017eok v spojoch rotor-dr\u00e1\u017eka je minimalizovan\u00fd pou\u017eit\u00edm mechanizmu, ktor\u00fd zni\u017euje v\u00f4\u013eu. Mechanizmus pozost\u00e1va z kooperat\u00edvne dr\u00e1\u017ekovan\u00fdch sam\u010d\u00edch a sami\u010d\u00edch \u010dlenov. Jeden \u010dlen je tvoren\u00fd dvoma koaxi\u00e1lne zarovnan\u00fdmi dr\u00e1\u017ekovan\u00fdmi segmentmi s koncov\u00fdmi plochami tvarovan\u00fdmi tak, aby sa klzne zachytili. Spojovacie zariadenie p\u00f4sob\u00ed na tieto segmenty axi\u00e1lnym za\u0165a\u017een\u00edm, \u010do sp\u00f4sobuje ich vz\u00e1jomn\u00e9 ot\u00e1\u010danie.<\/p>\n
