Iyi mhando ye shaft ine yakanaka machining performance. Mumashandisirwo anoshanda, haina chero porosity kana humwe hurema, saka haina kungoita yakanaka chitarisiko chisimbiso, asiwo ine kuita kwakanakisa.
Kune akawanda marudzi egiya shaft forgings. Inowanzo shandiswa giya rekugadzira zvinhu zvinosanganisira 40Cr, 42CrMo, 20CrMnMo, uye 20CrMnTi. 42CrMo uye 40Cr magiya ekufogisa akanyanya magiya magiya ekugadzira muindasitiri yekusimudza, nepo 20CrMn molybdenum uye 20CrMnTi anonyanya kushandiswa kugadzira magiya mumashini ekufambisa. Magiya mazhinji anoda magiya ekusimudza. Muna 38-42HRC, kuomarara kwekupisa kwegiya kwakawana kuita kwakanaka. Nekuda kweiyo yakanakisa yekupisa kurapwa kuomarara kweyekutanga, kuomarara kwe42CrMo kuri nani kupfuura iyo ye40Cr, iyo inowirirana zvakanyanya kune yayo. Saizvozvowo, pakuoma kwakafanana, simba riri pedyo zvikuru. Kusimba kwekusimba kwe40Cr ndeye 6 ~; Simba rekusimba re42CrMo i110kg/mm2, uye simba regoho i95kg/mm2. Kuita kuri nani kupfuura 40Cr.
40Cr zvinhu zvine kunaka kuomarara.
Kudzima mvura kunogona kuoma kusvika kudhayamita ye28-60 millimeters, nepo kudzima oiri kunogona kuoma kusvika kudhayamita ye15-40 millimeters. Mushure mekudzima uye kudzikisira, izvo zvinoratidzira zvakanakisa zvakakwana zvemichina zvimisikidzo, yakaderera notch senitivity, uye yakaderera-tembiricha kukanganisa kuoma. 40Cr gear forgings inowanzoiswa pasi pepamusoro-frequency quenching kana nitriding kurapwa mushure mekudzima uye kupisa. Kana kuoma kuri 174-229HBS, ine yakanaka machinability, ine hama machinability ye60%. Iyo kabhoni yemukati ye40Cr zvinhu forgings inochengetwa yakatenderedza 0.40%, nekudaro kuve nechokwadi musanganiswa wakanaka wesimba uye kuoma kwesimbi. Wedzera Cr element. (Cr, Fe) 3C. Yekutanga yekuforoma tembiricha ye40Cr giya forgings i1100 ~ 1150 ℃, uye tembiricha yekubira i800 ℃. Mushure mekugadzira, zviyero zvinopfuura 60 millimeters zvinoda kunonoka kutonhora.
Gear shaft mugadziri anoyeuchidza kuti zvinhu zvegiya shaft forgings zvinofanirwa kutanga zvasangana nezvinodiwa zvemamiriro ekushanda. Paunosarudza giya rekugadzira zvinhu, chinhu chekutanga kufunga nezve zvinodiwa zvemamiriro ekushanda. Alloy simbi inowanzoshandiswa kugadzira magiya efogi anoshanda pasi pekumhanya-mhanya, rinorema-basa, uye rinokanganisa mitoro. Kuvimbika kwepamusoro kunodiwa, uye zvakakosha kuti usarudze alloy simbi ine yakakwirira mechanical properties. Kana saizi yegiya ichidikanwa kuti ive diki sezvinobvira, yakakwirira-yakasimba alloy simbi ine pamusoro pekuomesa kurapa inofanira kushandiswa. Iyo giya yekufambisa mumakina emigodhi kazhinji ine simba rakakura, yakaderera kushanda kumhanya, uye yakakwira guruva zvemukati munzvimbo yakatenderedza. Naizvozvo, zvinhu zvakaita sesimbi yakakandwa kana simbi yakakandwa zvinowanzosarudzwa, asi kufambisa kweruzha kudiki, uye kuwanda kwekushanda kwemashini emuhofisi kwakadzikira. Iyi mhando ye shaft ine yakanaka machining performance. Mumashandisirwo anoshanda, haina chero porosity kana humwe hurema, saka haina kungoita yakanaka chitarisiko chisimbiso, asiwo ine kuita kwakanakisa.
