Nui nā ʻano o nā mea hana i ka hana ʻana, ʻo ia hoʻi ka lā, ka mea pololei, ka ʻaoʻao pālua, nā mea i loko, nā mea kūwaho, a me nā hāmeʻa bevel.
ʻO ka hana ʻana o ka pauka metallurgy gears e hōʻoia mua i nā mea.Nui nā kūlana maʻamau no nā mea hao pauka.Ke alakaʻi nei ʻo Iapana, ʻAmelika Hui Pū ʻIa a me Kelemania i ka honua i ka noiʻi ʻana i ka pauka metallurgy, aia i kēia manawa ka nui o nā mea waiwai no JIS, MPIF, a me DIN.
Loaʻa i nā Gears kekahi mau koi no ka ikaika, no laila pono e hoʻokō ka hana o nā mea i koho ʻia i nā koi huahana.I kēia manawa, ʻoi aku ka nui o nā mea i hoʻohana ʻia no nā hāmeʻa ʻo Fe-Cu-C-Ci mau mea (kūpono me JIS SMF5030, SMF5040, a me MPIF FN-0205, FN-0205-80HT maʻamau) Loaʻa nā mea Fe-Cu-C.
ʻO ka nui o ka pauka metallurgy gears, no ka mea, hoʻohana ʻia nā mea hana no ka hoʻouna ʻana, ʻoi aku ka kiʻekiʻe o nā koi no ka ikaika o nā mīkini, no laila e kiʻekiʻe ke kiʻekiʻe o nā huahana, a e hoʻomaikaʻi ʻia ke kūpaʻa o nā niho a ʻoi aku ka ikaika.
ʻO ka paʻakikī o ka pauka metallurgy gears e pili pono ana i ka mea, density grade a me ka hana hope o ka huahana.No laila ke kūʻai ʻoe i nā mea hana, pono e hōʻike ʻia ka pae paʻakikī ma ke kiʻi.
Ma hope o ka hoʻopaʻa ʻia ʻana o ka mīkini, i mea e hoʻomaikaʻi ai i ka ikaika a me ke kūpaʻa ʻana o ka mīkini, hoʻohui pinepine ʻia nā kaʻina hana ma hope o ka hoʻomaikaʻi ʻana i ka hana.ʻElua mau hana lapaʻau maʻamau:
1. Hoʻomaʻamaʻa ʻana i ka mahu wai ma luna.Hoʻopili ka mahu wai me Fe ma luna o ka ʻili o ke kaʻa e hana i kahi mea paʻa Fe₃O₄.He ʻoi aku ka paʻakikī o Fe₃O₄, hiki ke hoʻonui i ka pale ʻana a me ka paʻakikī o ka ʻili.
2. Carburizing lapaʻau
Hoʻohana like ka carburizing o nā mīkini mīkini maʻamau, carbonitriding a me quenching i nā hihia he nui e hoʻomaikaʻi i ka paʻakikī o ka ʻili.
