Niki kimenyetso cya kimwe cya kabiri cyavunitse
Niba ari murwego rwibibazo byihuta byikinyabiziga, birashobora gutuma imodoka ihagarara cyangwa uruziga rwatakaye, uruziga rwihuriro ruzana ibinyabiziga bigereranya uburinganire bwimodoka, bigatuma imodoka yihuta cyane yimodoka, umutambiko nawo urazwi nka shitingi.Muri sisitemu yo kohereza ibinyabiziga, igice cya kabiri kigira uruhare runini, ni uruziga rwo gutwara no gutandukanya itandukaniro.Impera yimbere ihujwe muri kimwe cya kabiri-shaft ibikoresho na spines, naho impera yinyuma ihujwe na hub na flange.Imiterere yimodoka itwara ibinyabiziga biterwa nuburyo bwimiterere ya axle.Ukurikije imiterere itandukanye yimbaraga zumutwe, irashobora kugabanywamo igice kireremba hejuru yumurongo wuzuye.Birashobora kugaragara ko umutambiko wimodoka nigice cyingenzi cyimodoka mugutwara burimunsi, kandi umutekano wibinyabiziga biterwa nimikorere ya axle.Nyuma yigihe kinini cyumunaniro wa torsional ningaruka, umutambiko wimodoka biroroshye kuganisha ku kunama, kuvunika, torsion, skew hamwe no kwinyoza amenyo.Ivunika ryimodoka isanzwe ifite ubwoko bwimiterere ikurikira:
Lix Helix ya shitingi yaravunitse;
(2) Hariho ibice bivanze no kuvunika mugice cyigice cya kimwe cya kabiri;
Sp umugozi wacyo wacitse;
.
(5) Ibindi byavunitse bya morfologiya nibice bya shaft.
