V t\u00e9to studii jsme zjistili, \u017ee ohybov\u00e1 tuhost ozuben\u00e9ho v\u011bnce je velmi ovlivn\u011bna zuby. Zkosen\u00e1 pata ozuben\u00e9ho v\u011bnce je v\u011bt\u0161\u00ed ne\u017e \u0161\u00ed\u0159ka dr\u00e1\u017eky. Ohybov\u00e1 tuhost ozuben\u00e9ho v\u011bnce se tedy li\u0161\u00ed v z\u00e1vislosti na \u0161\u00ed\u0159ce zubu, kter\u00e1 se zvy\u0161uje s tlou\u0161\u0165kou st\u011bny v\u011bnce. Krom\u011b toho zm\u011bna tlou\u0161\u0165ky st\u011bny v\u011bnce \u0161nekov\u00e9ho kola vede k men\u0161\u00ed odchylce od konstruk\u010dn\u00ed specifikace.
Pro pochopen\u00ed vlivu zubu na ohybovou tuhost \u0161nekov\u00e9ho za\u0159\u00edzen\u00ed je d\u016fle\u017eit\u00e9 zn\u00e1t tvar ko\u0159ene. Evolventn\u00ed zuby jsou n\u00e1chyln\u00e9 k ohybov\u00e9mu nam\u00e1h\u00e1n\u00ed a mohou se zlomit za extr\u00e9mn\u00edch podm\u00ednek. Kontrola zlomen\u00ed zubu m\u016f\u017ee tento probl\u00e9m ovlivnit ur\u010den\u00edm tvaru ko\u0159ene a ohybov\u00e9 tuhosti. Optimalizace tvaru ko\u0159ene p\u0159\u00edmo na za\u0159\u00edzen\u00ed minimalizuje ohybov\u00e9 nap\u011bt\u00ed v evolventn\u00edm zubu.
