imathiriyeli 40cr

I-40Cr yinombolo yentsimbi ye-GB esemgangathweni e-China, kunye ne-40Cr yensimbi yenye yezona zisetyenziswa kakhulu kwi-industry yemveliso yomatshini.Ineempawu ezilungileyo ezibanzi zomatshini, ukuqina okuhle kobushushu obuphantsi kunye ne-notch ephantsi sensitivity.Ukuqina kwentsimbi, xa kucinywa amanzi. ukuqina kwi-Ф 28 ~ 60 mm, xa ukucima i-oyile kunzima ukuya kwi-Ф 15 ~ 40 mm. Intsimbi ifanelekile kwi-cyanidation kunye nokucima i-frequency ephezulu.Xa ubunzima buyi-174 ~ 229HB, i-machinability yesihlobo i-60%. ukwenza iimbumba zeplastiki ezinobungakanani obuphakathi.

Intsimbi ephakathi kwekhabhoni epholileyo, i-cold heading die steel.Intsimbi inexabiso eliphakathi, kulula ukuyiqhuba kwaye inokufumana ubunzima obuthile, iplastiki kunye nokuxhatshazwa kwe-abrasion emva konyango olufanelekileyo lobushushu.I-Normalizing inokuphucula ukusebenza kokusika okungenanto ngokukhuthaza ukulungiswa kwe-microstructure kunye ukusondela kwi-equilibrium state.I-Tempered kwi-550 ~ 570 ℃, insimbi ineyona nto ingcono kakhulu ye-mechanical properties.Ubunzima bentsimbi buphezulu kunentsimbi ye-45, ifanelekile ukucima i-frequency, ukucima umlilo kunye nolunye unyango olunzima.

Amalungu e-Shaft yenye yeendawo eziqhelekileyo ezihlala zidibana noomatshini.Isetyenziselwa kakhulu ukuxhasa amacandelo othumelo, ukuhambisa i-torque kunye nomthwalo.Amalungu e-shaft ajikeleza amalungu omzimba, ubude bawo bukhulu kunobubanzi, ngokubanzi buqulunqwe yi-cocentric shaft cylindrical. umphezulu, umphezulu we-conical, umngxuma wangaphakathi kunye nentambo kunye nesiphelo esihambelanayo somphezulu.Ngokuhambelana nemilo eyahlukeneyo yesakhiwo, iindawo ze-shaft zinokwahlulwa zibe yi-shaft optical, i-shaft step, i-hollow shaft kunye ne-crankshaft.

I-40Cr yinto eqhelekileyo yeengxenye ze-shaft. Ixabiso eliphantsi kwaye linokufumana umsebenzi ongcono wokusika emva kokucima kunye nokucaphuka (okanye ukulinganisa), kwaye unokufumana iipropathi eziphezulu ezibanzi zoomatshini ezifana namandla kunye nokuqina. Emva kokucima, ukuqina komphezulu kunokufikelela kwi-45 ~ 52HRC.

I-40Cr isetyenziswa ngokubanzi kwimveliso yomatshini. Olu hlobo lwensimbi luneempawu ezintle zomatshini.Le yintsimbi ye-carbon alloy ephakathi kunye nokusebenza kakuhle kokucima, i-40Cr ingaba nzima ukuya kwi-HRC45 ~ 52. Ngoko ke, ukuba ubunzima bomhlaba bufuna ukuphuculwa kunye neempawu eziphezulu zemishini ye-40Cr kulindeleke ukuba ifakwe ekudlalweni, unyango lokucinywa komphezulu we-high-frequency luhlala luqhutywa emva kokulungiswa kwe-40Cr, ngokuqina ukuya kuthi ga kwi-55-58hrc, ukuze kufumaneke ukuqina komphezulu ofunekayo kunye nokugcina ukuqina okuhle kwentliziyo.
