Ibikoresho bya spiral, amashoka yo gutwara no gutwara ibyuma birahuza ahantu hamwe, kandi inguni yo guhuza irashobora kuba uko bishakiye, ariko mubice byinshi byo gutwara ibinyabiziga, ibikoresho nyamukuru bigabanya ibikoresho byateganijwe bihagaritse kuri 90 ° kuruhande. Bitewe no guhuzagurika mumaso yanyuma yinyo yinyo, byibuze bibiri cyangwa byinshi byinyo yinyo yinyo icyarimwe icyarimwe. Kubwibyo, ibikoresho bya spiral bevel birashobora kwihanganira umutwaro munini. Byongeye kandi, amenyo yi bikoresho ntabwo asunikwa icyarimwe hejuru yuburebure bwuzuye bw amenyo, ariko buhoro buhoro amenyo. Impera imwe ihora ihindukirira ku rundi ruhande, ku buryo ikora neza, ndetse no ku muvuduko mwinshi, urusaku no kunyeganyega ni bito cyane.

Ibikoresho bya Hypoid, amashoka yo gutwara no gutwara ibikoresho ntibishobora gutandukana ahubwo bihurira mumwanya. Imfuruka zihuza ibikoresho bya hypoid ahanini ni perpendicular ku ndege zitandukanye kuri 90 °. Igikoresho cyo gutwara ibinyabiziga gifite hejuru cyangwa kumanuka ugereranije na shitingi yimodoka (ivugwa hejuru cyangwa hepfo hejuru). Iyo offset ari nini kurwego runaka, igikoresho kimwe gishobora kunyura mubindi bikoresho. Muri ubu buryo, ibyuma bifatanye birashobora gutondekwa kumpande zombi za buri gikoresho, kikaba ari ingirakamaro mu kongera imbaraga mu gushyigikira no kwemeza neza amenyo y’ibikoresho, bityo ubuzima bwacyo bukongera. Birakwiriye binyuze muburyo bwimodoka.

Bitandukanyeibikoresho bya spiral aho inguni ya helix yo gutwara no gutwara ibinyabiziga bingana kuko amashoka yibikoresho byombi arahuza, axis ya offset ya hypoid gear couple ituma ibikoresho byo gutwara helix inguni iruta inguni ya moteri ya helix. Kubwibyo, nubwo modulus isanzwe ya hypoid bevel gear couple iringaniye, modulus yanyuma yo mumaso ntabwo ihwanye (modulus yanyuma yo mumaso yibikoresho byo gutwara irarenze modulus yanyuma yimyenda yibikoresho). Ibi bituma ibikoresho byo gutwara bya kwasi-byikubye kabiri byogukwirakwiza ibyuma bya diametre bifite diameter nini nimbaraga nziza nubukomezi kuruta ibikoresho byo gutwara ibyuma bikwirakwiza. Byongeye kandi, bitewe na diameter nini na helix inguni yo gutwara ibikoresho bya hypoid bevel yoherejwe, guhangayikishwa no kumenyo hejuru y amenyo biragabanuka kandi ubuzima bwa serivisi bwiyongera.

Nyamara, iyo ihererekanyabubasha ari rito, ibikoresho byo gutwara ibyuma bya kwasi-byikubye kabiri byoherejwe ni binini cyane ugereranije nibikoresho byo gutwara ibikoresho bya spiral. Muri iki gihe, birarenze guhitamo ibikoresho bya spiral.
