Hoʻokaʻawale ʻia nā hāmeʻa bevel spiral i ʻelua mau ʻano, ʻo ka mea he spiral bevel gear, nona ka axle nui a me ka axle liʻiliʻi e hui ai;ʻo ka mea ʻē aʻe, he ʻano hiʻohiʻona bevel hypoid, me kahi mamao offset ma waena o ke koʻi nui a me ke koʻi liʻiliʻi.Hoʻohana nui ʻia nā mea hoʻokalakupua spiral i nā kahua hoʻoili mechanical e like me nā kaʻa, ka mokulele, a me ka mining ma muli o ko lākou mau pono e like me ka nui overlap coefficient, ka ikaika o ka lawe ʻana, ka nui o ka hoʻouna ʻana, ka haʻahaʻa haʻahaʻa, a me ka leo haʻahaʻa.ʻO kona mau hiʻohiʻona:
1. He laina pololei ka laina niho, e ku ana ma ka piko o ka cone, e emi ana ka niho.
2. Helical bevel gear: ʻO ka laina niho he laina pololei a pili i kahi kiko, e emi ana ka niho.
3. ʻO nā kāʻei bevel spiral: nā mea hiki ke hoʻihoʻi ʻia (pono nō hoʻi no nā mea hana o ke kiʻekiʻe like).
4. Cycloid spiral bevel gear: contour niho.
5. ʻO nā niho ʻōniʻoniʻo ʻōniʻoniʻo zero-degree: ʻO nā niho hōʻemi pālua, βm=0, i hoʻohana ʻia e pani i nā ʻūhā bevel pololei, me ke kūpaʻa ʻoi aku ka maikaʻi, akā ʻaʻole maikaʻi e like me nā niho bevel spiral.
6. ʻO ka niho cycloid zero-degree bevel gear: Contour niho, βm=0, hoʻohana ʻia no ke pani ʻana i nā ʻūhā bevel pololei, me ka paʻa ʻoi aku ka maikaʻi, akā ʻaʻole maikaʻi e like me nā niho bevel spiral.
7. Hoʻokaʻawale nui ʻia nā ʻano kiʻekiʻe o nā niho o nā ʻāpana bevel spiral i nā niho liʻiliʻi a me nā niho kiʻekiʻe like.ʻO nā niho i hōʻemi ʻia, ʻo ia nā niho i hoʻemi ʻia ke poʻo like ʻole, nā niho i hoʻemi ʻia ke poʻo like ʻole a me nā niho hōʻemi pālua.
8. Nā niho contour: ʻo nā niho o ka hopena nui a me ka hopena liʻiliʻi o ke kiʻekiʻe like, hoʻohana maʻamau no ka oscillating bevel gears.
9. ʻO nā niho ʻokiʻoki ʻole isotopic space: ʻokoʻa nā piko o ka subcone, ka cone luna a me ka cone kumu.
