Mu gawo la makina opatsirana, magiya ozungulira ndi zida za helical Nthawi zambiri zimabweretsa malingaliro ofanana chifukwa cha mapangidwe awo ogometsa omwe cholinga chake ndi kupititsa patsogolo mphamvu ndi kuchepetsa phokoso. Komabe, kumvetsetsa kwapang'onopang'ono kumawonetsa kusiyana kosiyana pakati pa mitundu iwiri ya zida izi.

Magiya ozungulira amakhala ndi mano omwe amazungulira mozungulira mozungulira, ngati chikwapu. Kapangidwe kameneka kamathandizira kulumikizana bwino komanso kusalumikizana kwa mano, kuchepetsa kugwedezeka ndi phokoso. Malo awo otalikirapo okhudzana ndi mano amakulitsa mphamvu yonyamula katundu ndi kulimba, kuwapangitsa kukhala abwino pamakina olondola komanso kugwiritsa ntchito zakuthambo komwe kumayenera kukhala kolondola kwambiri komanso kosalala.

Kumbali ina, zida za helical,zida zozunguliramagiya a bevel ali ndi mano omwe amapendekeka pa ngodya ya giya. Kachitidwe kameneka kamalola kuti mano agwire pang'onopang'ono, mofanana ndi magiya ozungulira, kuchepetsa kugwedezeka ndi kupititsa patsogolo kufalitsa bwino. Magiya a helical amapambana potumiza torque yayikulu ndipo amagwiritsidwa ntchito kwambiri pantchito zolemetsa, monga makina am'mafakitale ndi ma transmission amagalimoto, komwe magwiridwe antchito ndi moyo wautali ndizofunikira.

Dinani ulalo wowonera kuti musankhe zinazida za helical
Dinani ulalo wowonera kuti musankhe zida zambiri za bevel

Ngakhale magiya onse awiriwa amagawana mwayi wolumikizana pang'onopang'ono ndi mano, magiya ozungulira amatsindika kulondola komanso kusalala, pomwe magiya a helical amayang'ana mphamvu ya torque komanso kulimba. Kusankha pakati pawo kumatengera zofunikira za pulogalamuyo, kuphatikiza kufunikira kolondola, kuchuluka kwa katundu, ndi malo ogwirira ntchito.

Pomaliza, magiya ozungulira ndi ma helical, ngakhale amafanana, amakwaniritsa zosowa zosiyanasiyana. Kumvetsetsa kusiyana kumeneku ndikofunikira pakusankha mtundu wa gear womwe uli woyenera pamakina aliwonse omwe amaperekedwa.
