1. Zida zowongoka za bevel ndiye zida zoyambira kwambiri.Kukonzekera ndikosavuta, koma kulondola kwapatsirana ndikosauka kwambiri, ndipo chiŵerengero chapanthawi yomweyo sichili cholondola.Amangopatsirana ngati kusintha kwakukulu kwa njira, ndipo zofunikira za chiŵerengero cha liwiro ndi kufalitsa sizokhwima., Monga kukweza ndi kutsika kwa tebulo logwirira ntchito la ng'ombe yamphongo ya mutu wa ng'ombe, shaft yogwiritsira ntchito, ndi zina zotero, zoyenera ku bungwe lotsika kwambiri.Ku

2. Mphamvu ya spiral bevel gear ndiyo yabwino kwambiri, ndipo magawo ogwirira ntchito m'mbali zonse ndiabwino kwambiri.Pali ma giya ozungulira ozungulira mkati mwa shaft yoyendetsa komanso kumbuyo kwagalimoto.Ntchito zake ndi izi:
Ubwino: mphamvu yopatsirana kwambiri, kukana kukangana kochepa, chiŵerengero cholondola chapanthawi yomweyo, torque yayikulu, komanso yoyenera kufalitsa mwachangu kwambiri.
Chilema: mtengo wokwera wopangira.Chifukwa cha zinthu zomwe zimapangidwira ndikuyika, zimakhala zovuta kuzindikira digirii yabwino kwambiri, ndipo iyenera kukhala yosalala.Zabwino kwambiri ndikusamba kwamafuta osalala.
