Mu rwego rwo kohereza imashini, ibikoresho bya spiral na ibikoresho bya tekinike akenshi bikangura imyumvire isa bitewe nuburyo bukomeye bw amenyo agamije kuzamura imikorere no kugabanya urusaku. Ariko, gusobanukirwa neza kwerekana itandukaniro riri hagati yubwoko bubiri bwibikoresho.

Ibikoresho bya spiral biranga amenyo yumuyaga muburyo bukomeza buzunguruka, bisa na corkscrew. Igishushanyo cyoroshya gusezerana no kugabanya amenyo, kugabanya kunyeganyega n urusaku. Ahantu hanini ho guhuza amenyo yongerera ubushobozi bwo kwikorera imitwaro no kuramba, bigatuma biba byiza kumashini zisobanutse hamwe nibisabwa mu kirere aho ubunyangamugayo buhanitse kandi bukora neza.

Kurundi ruhande, ibikoresho bya tekinike,ibikoresho bya spiralibyuma bya bevel bifite amenyo yegamiye ku nguni ya gare. Uku guhitamo kwemerera amenyo gahoro gahoro, bisa nibikoresho bya spiral, kugabanya imizigo no kongera uburyo bwo kohereza. Ibikoresho bifasha cyane mu kohereza umuriro mwinshi kandi bikoreshwa cyane mubikorwa biremereye cyane, nk'imashini zinganda no kohereza amamodoka, aho imikorere ikomeye no kuramba ari ngombwa.

Kanda ahanditse reba kugirango uhitemo byinshiibikoresho bya tekinike
Kanda ahanditse reba kugirango uhitemo ibikoresho byinshi bya bevel

Mugihe ubwoko bwombi bwibikoresho bisangiye ibyiza byo guhuza amenyo gahoro gahoro, ibyuma bizenguruka byibanda kubisobanutse neza kandi neza, mugihe ibyuma bya tekinike byibanda kubushobozi bwa torque no kuramba. Guhitamo hagati yabo gushingira kubisabwa byihariye bya porogaramu, harimo gukenera neza, ubushobozi bwo gutwara ibintu, hamwe n’ibidukikije bikora.

Mu gusoza, ibikoresho bya spiral na helical, nubwo bigaragara ko bisa, bihuza imikorere itandukanye. Gusobanukirwa itandukaniro nurufunguzo rwo guhitamo uburyo bwiza bwibikoresho bya sisitemu iyo ari yo yose yoherejwe.
