Lapho ucubungula induku ye-piston, uma kusetshenziswa insimbi engu-45 #.Ngaphansi kwezimo ezijwayelekile, ngokomthwalo wenduku ye-piston ayinkulu, okungukuthi, izosetshenziselwa ukwenza insimbi engu-45 #.Njengoba insimbi engu-45 # isetshenziswa kakhulu ensimbi yesakhiwo ecishiwe ephakathi kwekhabhoni, ngokwalokhu, kungenxa yokuthi yona ngokwayo izoba namandla aphakeme kanye nokusebenza kahle.
Emkhiqizweni wensimbi we-45 # we-piston rod, ikakhulukazi ngemuva kokuphathwa kahle kokushisa, kungaba nengqondo kakhudlwana ukuthi uthole izinga elithile lokuqina, i-ductility kanye nokumelana nokugqoka okuhlobene, ngokubheka lokhu, ku-45 # Insimbi, empeleni, ingenye yezinto ezisetshenziswa kakhulu ezibalulekile lapho induku yepiston icutshungulwa.
Ngaphezu kwalokho, ukucutshungulwa kwenduku ye-piston, uma kusetshenziswa insimbi engu-45 #, induku ye-piston lapho umthwalo ukhulu kakhulu, okungukuthi, ukusetshenziswa kwensimbi engu-40Cr yokukhiqiza.Njengoba insimbi engu-40Cr iyinsimbi ecishwa ngekhabhoni ephakathi nendawo, ukuqina kwayo kungcono, ukuqina kwayo okuphansi kwezinga lokushisa.Ikakhulukazi uma kungemuva kokucisha, izoba nezakhiwo ezingcono kakhulu zemishini.
Ngale ndlela, empeleni kufanele sinake ukuthi kungaqinisekisa ukuthi i-piston rod ingaba nokuqina okwanele komsebenzi.Ngenxa yalokhu, ukusetshenziswa kwensimbi engu-40Cr ekwenzeni i-piston rod kuvame ukuthi izosetshenziselwa umthelela omkhulu noma ukuthunyelwa kwemithwalo esindayo okudinga imishini emikhulu ye-piston.
Ekugcineni, eqinisweni, kufanele sinake incazelo engenhla yento, okungukuthi, lapho induku ye-piston icubungula izinto ezisetshenziswa kakhulu.Kodwa-ke, ngaphezu kwezinhlobo ezimbili ezishiwo ngenhla zezinto zokucubungula i-piston rod, kuzoba khona insimbi ye-GCR15 noma i-SUS304, esetshenziswa ngokuqondile ukwenza izinto zokucubungula ku-piston rod.
