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 hapa nui o ka hoʻohana ʻana no ka hoʻopili ʻana i nā mea hana 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 hoʻomaʻamaʻa wela maikaʻi o ka mua, ʻoi aku ka maikaʻi o ka paʻakikī o 42CrMo ma mua o ka 40Cr, kahi pili pili 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 hoʻoluliluli ʻana, hōʻike ka mea i nā waiwai mechanical piha maikaʻi loa, haʻahaʻa notch sensitivity, a me ka haʻahaʻa haʻahaʻa hopena 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%, no laila e hōʻoiaʻiʻo 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 hana ʻana, ʻoi aku ka nui o ka 60 millimeters e pono ai ka 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 hoʻohana pono, ʻaʻohe porosity a i ʻole nā hemahema ʻē aʻe, no laila ʻaʻole ia he hōʻoia maikaʻi wale nō, akā he hana maikaʻi nō hoʻi.
