Spiral bevel gear, nkhwangwa zoyendetsera ndi magiya oyendetsedwa zimadutsana pamalo amodzi, ndipo mbali ya mphambano imatha kukhala yosasunthika, koma m'ma axle amagalimoto ambiri, ma giya akulu ochepetsera amakonzedwa molunjika pamakona a 90 ° njira.Chifukwa cha kuphatikizika kwa nkhope zomapeto za mano a giya, mapeyala awiri kapena kupitilira apo mano a giya nthawi imodzi.Chifukwa chake, zida za bevel zozungulira zimatha kupirira katundu wokulirapo.Kuonjezera apo, mano a gear sakhala otsekedwa nthawi imodzi pamtunda wonse wa dzino, koma pang'onopang'ono amapangidwa ndi mano.Mapeto amodzi amatembenuzidwira mbali ina, kotero kuti imagwira ntchito bwino, ndipo ngakhale pa liwiro lalikulu, phokoso ndi kugwedezeka kumakhala kochepa kwambiri.

Magiya a Hypoid, nkhwangwa zamagalimoto ndi magiya oyendetsedwa sizimadutsana koma zimadutsa mumlengalenga.Makona odutsana a magiya a hypoid nthawi zambiri amakhala olunjika ku ndege zosiyanasiyana pamakona a 90 °.Chombo choyendetsa galimoto chimakhala ndi chokwera kapena chotsika chotsika chokhudzana ndi shaft yoyendetsedwa (yomwe imatchedwa kumtunda kapena kutsika molingana).Chingwe cha giya chikakhala chachikulu pamlingo winawake, shaft imodzi ya giya imatha kudutsa pa shaft ina.Mwanjira iyi, mayendedwe ophatikizika amatha kukonzedwa mbali zonse za giya lililonse, zomwe zimakhala zopindulitsa kukulitsa kulimba kwa chithandizo ndikuwonetsetsa kuti mano agiya ali olondola, potero amawonjezera moyo wa magiya.Ndi yoyenera pa ma axles amtundu wamtundu.

Mosiyana ndi ma giya ozungulira ozungulira pomwe ma helix oyendetsa ndi magiya oyendetsedwa ndi ofanana chifukwa nkhwangwa za ma giya awiriwa zimadutsana, ma axis offset of the hypoid gear pair imapangitsa kuti giya yoyendetsa helix ikhale yayikulu kuposa ngodya yoyendetsedwa ya gear helix.Chifukwa chake, ngakhale modulus wamba wa hypoid bevel gear giya ndi wofanana, modulus ya nkhope yomaliza sifanana (mapeto a nkhope ya giya yoyendetsa ndi yayikulu kuposa modulus yakumaso kwa zida zoyendetsedwa).Izi zimapangitsa kuti zida zoyendetsera ma giya a quasi-side-side-side bevel gear transmission kukhala ndi mainchesi okulirapo komanso mphamvu zabwino komanso zolimba kuposa zida zoyendetsera zomwe zimayenderana ndi spiral bevel gear transmission.Kuphatikiza apo, chifukwa cha mainchesi akulu ndi ngodya ya helix ya giya yoyendetsa ya hypoid bevel gear transmission, kukhudzana kwapa mano kumachepetsedwa ndipo moyo wautumiki ukuwonjezeka.

Komabe, kutumizako kukakhala kochepa, zida zoyendetsa za quasi-double-sided bevel gear transmission zimakhala zazikulu kwambiri poyerekeza ndi zida zoyendetsera za spiral bevel gear.Panthawiyi, ndizomveka kusankha zida za spiral bevel.
