He maikaʻi ka hana mīkini ʻana i kēia ʻano kumu. I nā noi kūpono, ʻaʻohe porosity a i ʻole nā hemahema ʻē aʻe, no laila ʻaʻole ia he hōʻoia maikaʻi wale nō, akā he hana maikaʻi loa.
Nui nā ʻano o ka hoʻoheheʻe ʻana i ka pahu. ʻO nā mea hana hoʻohana maʻamau ʻo 40Cr, 42CrMo, 20CrMnMo, a me 20CrMnTi. ʻO 42CrMo a me 40Cr nā mea hoʻoheheʻe i hoʻohana ʻia no ka hoʻopaʻa ʻana i nā mea hana i ka ʻoihana hoʻokiʻekiʻe, ʻoiai ʻo 20CrMn molybdenum a me 20CrMnTi ka mea i hoʻohana nui ʻia no ka hoʻopaʻa ʻana i nā mīkini i nā mīkini hoʻouna. ʻO ka hapa nui o nā hāmeʻa pono e hoʻokiʻekiʻe. I ka 38-42HRC, ua loaʻa ka hana maikaʻi o ka mālama ʻana i ka wela o nā mīkini. Ma muli o ka paʻakikī o ka mālama wela maikaʻi loa o ka mua, ʻoi aku ka maikaʻi o ka paʻakikī o 42CrMo ma mua o ka 40Cr, pili loa i kāna mea. Pēlā nō, ma ka paʻakikī like, kokoke loa ka ikaika. ʻO ka ikaika tensile o 40Cr he 6 ~; ʻO ka ikaika o ka tensile o 42CrMo he 110kg / mm2, a ʻo ka ikaika hoʻohua he 95kg / mm2. ʻOi aku ka maikaʻi o ka hana ma mua o 40Cr.
Loaʻa ka paʻakikī o ka mea 40Cr.
Hiki ke hoʻopaʻakikī ka hoʻopaʻa wai a hiki i ke anawaena o 28-60 millimeters, aʻo ka hoʻopau ʻana i ka aila hiki ke paʻakikī i ke anawaena o 15-40 millimeters. Ma hope o ka hoʻopau ʻana a me ka hoʻoulu ʻana, hōʻike ka mea i nā waiwai mechanical piha maikaʻi loa, haʻahaʻa notch sensitivity, a me ka haʻahaʻa haʻahaʻa haʻahaʻa hopena. ʻO ka 40Cr gear forgings e hoʻokau pinepine ʻia i ka hoʻopiʻi kiʻekiʻe kiʻekiʻe a i ʻole ka hoʻomaʻamaʻa nitriding ma hope o ke kinai ʻana a me ka hoʻoulu ʻana. Ke 174-229HBS ka paʻakikī, loaʻa iā ia ka machinability maikaʻi, me ka machinability pili o 60%. Mālama ʻia ka ʻike kalapona o 40Cr material forgings ma kahi o 0.40%, pēlā e hōʻoia ai i kahi hui maikaʻi o ka ikaika a me ka paʻakikī o ke kila. Hoʻohui i ka mea Cr. (Cr, Fe) 3C. ʻO ka mahana forging mua o 40Cr gear forgings he 1100 ~ 1150 ℃, a ʻo ka mahana forging he 800 ℃. Ma hope o ka hoʻopaʻa ʻana, ʻoi aku ka nui ma mua o 60 millimeters pono e hoʻomaha mālie.
Hoʻomanaʻo ka mea hana ʻo Gear shaft e hoʻokō mua nā mea hana o ka shaft shaft i nā koi o nā kūlana hana. Ke koho ʻana i nā mea forging gear, ʻo ka mea mua e noʻonoʻo ai i nā koi o nā kūlana hana. Hoʻohana maʻamau ʻia ke kila Alloy no ka hana ʻana i nā mea hana forging e hana ana ma lalo o ka wikiwiki kiʻekiʻe, hana kaumaha, a me nā ukana hopena. Pono ka hilinaʻi kiʻekiʻe, a he mea nui e koho i ke kila kila me nā waiwai mechanical kiʻekiʻe. Inā ʻoi aku ka liʻiliʻi o ka nui o ka mīkini, pono e hoʻohana ʻia ke kila kila ikaika me ka hoʻopaʻa paʻakikī ʻili. ʻO ka hoʻoili ʻana i nā mīkini i nā mīkini mining maʻamau ka mana kiʻekiʻe, haʻahaʻa haʻahaʻa ka wikiwiki o ka hana, a me ka lepo kiʻekiʻe o ka lepo a puni. No laila, koho pinepine ʻia nā mea e like me ke kila kila a i ʻole ka hao, akā ʻoi aku ka liʻiliʻi o ka lawe ʻana i ka walaʻau, a ʻoi aku ka haʻahaʻa o ka hana ʻana o nā mīkini keʻena. He maikaʻi ka hana mīkini ʻana i kēia ʻano kumu. I nā noi kūpono, ʻaʻohe porosity a i ʻole nā hemahema ʻē aʻe, no laila ʻaʻole ia he hōʻoia maikaʻi wale nō, akā he hana maikaʻi loa.
