Igiya le-Spiral bevel, izimbazo zamagiya okushayela nashayelwa ziphambana endaweni eyodwa, futhi i-engeli yempambanomgwaqo ingaba ngokungafanele, kodwa kuma-axle amaningi okushayela imoto, igiya eliphambili elinciphisayo lihlelwa lime mpo nge-engeli engu-90° indlela.Ngenxa yokugqagqana kobuso bokugcina bamazinyo egiya, okungenani amapheya amabili noma ngaphezulu amazinyo egiya anezikhala ngesikhathi esisodwa.Ngakho-ke, i-spiral bevel gear ingamelana nomthwalo omkhulu.Ngaphezu kwalokho, amazinyo egiya awaxhunywanga ngesikhathi esisodwa ubude bezinyo eligcwele, kodwa kancane kancane afakwa amazinyo.Omunye umkhawulo uphendukela komunye umkhawulo ngokuqhubekayo, ukuze usebenze kahle, futhi ngisho nangesivinini esikhulu, umsindo nokudlidliza kuncane kakhulu.

Amagiya eHypoid, izimbazo zamagiya okushayela nawo ashayelwa awaphambani kodwa ahlangana emkhathini.Ama-engeli aphambanayo amagiya e-hypoid ngokuvamile ancike ezindizeni ezihlukene nge-engeli engu-90°.I-shaft yegiya lokushayela ine-offset eya phezulu noma eya phansi ehlobene ne-shaft yegiya eliqhutshwayo (okubizwa ngokuthi i-offset ephezulu noma ephansi ngokufanele).Uma i-offset inkulu ngokwezinga elithile, i-shaft eyodwa yegiya ingadlula komunye umshini wegiya.Ngale ndlela, ama-compact bearings angahlelwa ezinhlangothini zombili zegiya ngalinye, okuwusizo ekuthuthukiseni ukuqina kokusekelwa nokuqinisekisa ukuhlangana okulungile kwamazinyo egiya, ngaleyo ndlela kwandise impilo yamagiya.Ilungele ama-axle ohlobo lwe-drive.

Ngokungafani namagiya e-spiral bevel lapho ama-engeli e-helix okushayela kanye namagiya ashayelwayo elingana ngoba izimbazo zamapheya egiya ziyaphambana, i-axis offset ye-hypoid gear pair yenza i-engeli ye-helix yegiya lokushayela ibe nkulu kune-engeli ye-helix yegiya elishayelwa.Ngakho-ke, nakuba i-modulus evamile ye-hypoid bevel gear pair ilingana, i-modulus yobuso bokugcina ayilingani (i-modulus yobuso bokugcina yegiya lokushayela inkulu kune-end face modulus yegiya eliqhutshwayo).Lokhu kwenza igiya lokushayela le-quasi-double-sided bevel gear transmission libe nobubanzi obukhudlwana namandla angcono nokuqina kunegiya lokushayela le-spiral bevel gear transmission.Ngaphezu kwalokho, ngenxa yobubanzi obukhulu kanye ne-helix angle yegiya lokushayela le-hypoid bevel gear transmission, ingcindezi yokuxhumana endaweni yezinyo iyancishiswa futhi nempilo yesevisi iyakhula.

Kodwa-ke, lapho ukudluliselwa kukuncane, igiya lokushayela le-quasi-double-sided bevel gear transmission likhulu kakhulu uma liqhathaniswa negiya lokushayela legiya le-spiral bevel.Ngalesi sikhathi, kunengqondo kakhulu ukukhetha igiya le-bevel elivunguzayo.
