Isixhobo se-Spiral bevel, ii-axes zokuqhuba kunye neegiya eziqhutywayo zinqumla kwindawo enye, kwaye i-angle ye-intersection inokuba yinto engafanelekanga, kodwa kwii-axles ezininzi zokuqhuba iimoto, eyona nto iphambili yokunciphisa iperi icwangciswe ngokuthe nkqo kwi-90 ° indlela. Ngenxa yokudityaniswa kobuso bokugqibela bamazinyo egiya, ubuncinci izibini ezimbini okanye ngaphezulu zamazinyo egiya ngaxeshanye. Ke ngoko, i-spiral bevel gear inokumelana nomthwalo omkhulu. Ukongeza, amazinyo egiya awaxutywanga ngaxeshanye phezu kobude obupheleleyo bezinyo, kodwa ngokuthe ngcembe afakwe ngamazinyo. Esinye isiphelo sijika ngokuqhubekayo ukuya kwesinye isiphelo, ukuze sisebenze kakuhle, kwaye nangesantya esiphezulu, ingxolo kunye nokungcangcazela kuncinci kakhulu.

Iigiya zeHypoid, iiasi zokuqhuba kunye nezixhobo eziqhutywayo aziphambanisi kodwa zinqumla esithubeni. Ii-angles eziphambanisayo zeegiya ze-hypoid zixhomekeke kwi-perpendicular kwiindiza ezahlukeneyo kwi-angle ye-90 °. I-shaft yegiya yokuqhuba ine-offset ephezulu okanye ezantsi malunga ne-shaft yegiya eqhutywayo (ekubhekiselwa kuyo njenge-offset ephezulu okanye ephantsi ngokufanelekileyo). Xa i-offset inkulu ukusa kumlinganiselo othile, enye ishafti yegiya inokudlula komnye umngxuma wegiya. Ngale ndlela, iibheringi ezihlangeneyo zinokucwangciswa kumacala omabini egiya nganye, enenzuzo ekwandiseni ukuqina kwenkxaso kunye nokuqinisekisa ukuhlangana okuchanekileyo kwamazinyo egiya, ngaloo ndlela kwandisa ubomi beegiya. Ifanelekile kwii-axles zokuqhuba.

Ngokungafaniyoiigiya ze-bevel ezijikelezayo apho ii-engile ze-helix zokuqhuba kunye neegiya eziqhutywayo zilingana ngenxa yokuba i-axes ye-gear pairs iyanqumla, i-axis offset ye-hypoid gear pair yenza i-angle ye-helix yokuqhuba i-angle enkulu kune-engile ye-helix eqhutywayo. Ke ngoko, nangona imodyuli eqhelekileyo ye-hypoid bevel gear pair ilingana, imodyuli yobuso bokugqibela ayilingani (isiphelo sobuso bemodyuli yegiya yokuqhuba inkulu kunesiphelo sobuso bemodyuli yegiya eqhutywayo). Oku kwenza ukuba igiya yokuqhuba yokuhanjiswa kwegiya ye-bevel ephindwe kabini ibe nobukhulu obukhulu kunye namandla angcono kunye nobungqongqo kunesixhobo sokuqhuba se-spiral bevel gear transmission. Ukongeza, ngenxa yobukhulu obukhulu kunye ne-helix engile yegiya yokuqhuba yokuhanjiswa kwegiya ye-hypoid bevel, uxinzelelo loqhagamshelwano kumphezulu wezinyo luyancitshiswa kwaye ubomi benkonzo buyanda.

Nangona kunjalo, xa ukuhanjiswa kuncinci, igiya yokuqhuba ye-quasi-double-side-side-side bevel gear transmission inkulu kakhulu xa ithelekiswa negiya yokuqhuba ye-spiral bevel gear. Ngeli xesha, kunengqiqo ngakumbi ukukhetha i-spiral bevel gear.
