Zida zozungulira, yomwe imadziwikanso kuti magiya a helical, imapereka zabwino zingapo zikagwiritsidwa ntchito pamakina opatsirana okha:

1. Smooth Operation: Maonekedwe a helix a mano a giya amalola kuti azigwira bwino ntchito popanda kugwedezeka pang'ono poyerekeza ndi magiya owongoka.
2. Kuthamanga Mwachete: Chifukwa cha kukhudzana kosalekeza kwa mano, magiya ozungulira amathamanga mwakachetechete ndipo amatulutsa phokoso lochepa poyerekeza ndi anzawo omwe ali ndi mano owongoka.
3. Kuchita Bwino Kwambiri: Kuphatikizika kwa magiya a helical kumapangitsa kuti pakhale kufalikira kwamphamvu kwamphamvu, popeza mano ambiri amalumikizana, zomwe zikutanthauza kuti kutsetsereka pang'ono ndi kutaya mphamvu.
4. Kuwonjezeka Kwakatundu: Mapangidwe a magiya ozungulira amatha kunyamula katundu wokwera popanda kufunikira kwa magiya akuluakulu, omwe amapindulitsa kwambiri pamapangidwe apang'ono.
5. Kutalika kwa Moyo Wautali: Kugawika kofanana kwa mphamvu pa mano a giya kumapangitsa kuti magiya azikhala ocheperako komanso moyo wautali.
6. Kutumiza kwa Torque:Zida zozunguliraimatha kutumiza torque yayikulu m'malo ang'onoang'ono, omwe ndi abwino kwa mapulogalamu omwe malo amakhala okwera mtengo.
7. Kuyanjanitsa Bwino: Amathandizira kuwongolera bwino kwa ma shafts, kuchepetsa kufunikira kwa zigawo zina zolumikizirana komanso kufewetsa kapangidwe kake.
8. Axial Thrust Management: Mphamvu yomwe imapangidwa panthawi yogwira ntchito ndi axial, yomwe imatha kuyendetsedwa mosavuta ndi mapangidwe oyenera.
9. Kuyenerera Kuthamanga Kwambiri: Magiya ozungulira ndi oyenera kugwiritsa ntchito kuthamanga kwambiri chifukwa chotha kunyamula katundu wambiri ndikusunga bwino.
10. Kulimbana ndi Shock Load Resistance: Amatha kuyamwa bwino katundu wodabwitsa chifukwa chakuchita pang'onopang'ono komanso kusagwira ntchito kwa mano.
11. Kuchita Bwino Kwam'mlengalenga: Kwa mphamvu yoperekedwa yamagetsi, magiya ozungulira amatha kukhala ophatikizika kuposa magiya ena.
12. Kusamalira Pang'onopang'ono: Njira yopangira molondola komanso ngakhale kugawa katundu kumabweretsa magiya omwe amafunikira kusamalidwa pang'ono pakapita nthawi.
13. Kudalirika: Magiya a Spiral amadziwika chifukwa chodalirika pamakina otumizirana ma automatic, pomwe magwiridwe antchito amafunikira.

Ubwino umenewu umapangazida zozungulirachisankho chodziwika bwino chamitundu yosiyanasiyana yamakina ndi zida zomwe zimafuna kufalitsa mphamvu zokha komanso kothandiza.
