Umunyururu ni igikoresho gisanzwe cyo kohereza ubutumwa. Ihame ry'imikorere y'umunyururu ni ukugabanya ubukana hagati y'umunyururu n'umuyoboro unyuze mu munyururu ugose kabiri, bityo bikagabanya igihombo cy'ingufu mu gihe cyo kohereza ubutumwa, bityo bigatuma habaho imikorere myiza yo kohereza ubutumwa. Gukoresha umunyururu bikunze kwibanda cyane rimwe na rimwe hamwe n'imbaraga nyinshi n'umuvuduko ugenda buhoro, bigatuma umunyururu ugira inyungu zigaragara.
Ihererekanya ry'iminyururu rikoresha iminyururu itandukanye n'ibindi bikoresho biyishyigikira, harimo iminyururu y'ibikoresho byo kohereza, iminyururu ya CVT, iminyururu miremire, iminyururu migufi, iminyururu y'imivuduko ibiri, iminyururu y'amaboko yo kohereza, iminyururu y'amaboko yo kohereza, harimo iminyururu y'ibikoresho, Umunyururu wa CVT, umunyururu muremure, umunyururu mugufi, umunyururu mugufi. Umunyururu w'iminyururu wa t-pitch, umunyururu w'iminyururu ibiri, umunyururu w'amaboko yo kohereza. Umunyururu w'iminyururu uremereye, umunyururu w'iminyururu ibiri, umunyururu w'iminyururu migufi, umunyururu w'isahani, nibindi.
1. Umunyururu w'icyuma kidakoresha ifu
Umunyururu w'icyuma kidashonga, nk'uko izina ribigaragaza, ni umunyururu ukozwe mu cyuma kidashonga nk'igikoresho cy'ingenzi gikoreshwa mu gucukura. Umunyururu urwanya ingese neza kandi ushobora kwimenyereza ahantu hakorerwa ubushyuhe bwinshi n'ubukonje. Ahantu h'ingenzi iminyururu y'icyuma kidashonga ikoreshwa ni mu nganda zikora ibiribwa, imiti n'imiti.
2. Ibikoresho bikenewe mu gukora iminyururu yisiga ni icyuma cyihariye gikozwe mu mavuta yisiga. Umunyururu ukozwe muri iki cyuma urinda kwangirika no kwangirika, wisiga burundu, ntukenera kubungabungwa, kandi biroroshye kuwukoresha. Nanone ukora igihe kirekire. Iminyururu yisiga ikwiriye imiyoboro y’ibiribwa yikora kandi irinda kwangirika cyane kandi igoye kuyibungabunga.
3. Umunyururu wa rubber
Uburyo bwo gukora umugozi w'urunigi ni ugushyiramo isahani ifite ishusho ya U ku mugozi wo hanze w'umugozi usanzwe, no gupakira imigozi itandukanye inyuma y'isahani ifatanye. Imigozi myinshi y'urunigi ikoresha umugozi karemano witwa NR cyangwa Si, bituma umugozi udashira neza, ukagabanya urusaku rw'imikorere, kandi ukongera ubushobozi bwo kudahindagura.
4. Umunyururu ukomeye cyane
Umunyururu ukomeye cyane ni umunyururu wihariye uhindura imiterere y'umunyururu hashingiwe ku munyururu w'umwimerere. Amasahani y'umunyururu, imyobo n'udupira byose bitunganywa kandi bigakorwa mu buryo bwihariye. Iminyururu ikomeye cyane ifite imbaraga zo gukurura neza, iri hejuru ya 15%-30% ugereranyije n'iminyururu isanzwe, kandi ifite ubushobozi bwo kurwanya ingaruka no kurwanya umunaniro.
