Ibhola lensimbi elithwalayo liyibhola lensimbi elivamile lezimboni elisetshenziselwa ukuhambisa izingxenye kuma-bearings nakwezinye izinto zokusebenza zemishini. Linezici zamandla aphezulu, ubulukhuni kanye nokumelana nokuguguleka, ngakho-ke ukulawula ngokwenqubo kanye nomphumela kubaluleke kakhulu. Okulandelayo kuzokwethula inqubo yokwelapha ukushisa kanye nomphumela wamabhola ensimbi athwalayo.
Ukwelashwa ngokushisa kubhekisela ochungechungeni lwezinqubo zobuchwepheshe ngokushisa nokupholisa izinto ukuze kushintshwe isakhiwo senhlangano kanye nezakhiwo zezinto. Inqubo yokwelashwa ngokushisa yamabhola ensimbi athwalayo ivame ukufaka izinyathelo ezifana nokushisa, ukucima kanye nokufaka i-carburizing.
Ukushisa kuyinqubo yokushisa ibhola lensimbi elicishiwe lifinyelele ekushiseni okuthile, bese ulipholisa ngesikhathi esifanele. Inhloso yokushisa ukususa ukucindezeleka kwangaphakathi okubangelwa ngesikhathi sokushisa, ukunciphisa ukuphuka, nokuthuthukisa ukuqina kanye nokuqina. Izinga lokushisa nesikhathi sokushisa ngokuvamile kunqunywa ngokuya ngokwakheka kanye nezidingo zebhola lensimbi elicishiwe. Izinga lokushisa lokushisa liphansi kakhulu noma isikhathi sifushane kakhulu, kungaholela ekwandeni kokucindezeleka okusele, ukufudumala okunganele, kuthinte ukusebenza kwebhola lensimbi elicishiwe; Izinga lokushisa lokushisa liphezulu kakhulu noma isikhathi side kakhulu, kuzonciphisa ubulukhuni kanye nokumelana nokuguguleka. Ngakho-ke, ukulawula inqubo yokushisa kubaluleke kakhulu.
Okwesibili, ukucima kuyinqubo eyinhloko yokwelapha ukushisa kwebhola lensimbi elithwalayo, ngokushisa ibhola lensimbi elithwalayo lifike ezingeni lokushisa elibucayi, bese liphola ngokushesha, ukuze lihlelwe libe yi-martensite noma i-bainite. Ukucima kungathuthukisa ubulukhuni namandla ebhola lensimbi elithwalayo, kwandise ukumelana nokuguguleka kwalo kanye nokuphila kwenkonzo. Indawo yokupholisa enkambisweni yokucima imvamisa uwoyela, amanzi noma igesi, futhi indawo yokupholisa efanele ikhethwa ngokuya ngezidingo ezithile zebhola lensimbi elithwalayo. Izinga lokushisa lokucima, isivinini sokupholisa kanye nokukhetha indawo yokupholisa kuzoba nomthelela obalulekile esakhiweni nasekusebenzeni kwebhola lensimbi elithwalayo. Izinga lokushisa eliphakeme kakhulu noma isivinini sokupholisa esisheshayo kakhulu kungaholela ekuqhekekeni nasekuguqukeni; Izinga lokushisa liphansi kakhulu noma ijubane lokupholisa lihamba kancane kakhulu, okuzothinta ubulukhuni namandla.
I-Carburizing inqubo evamile yokuqinisa ubuso, ngokucwilisa ibhola lensimbi elithwalayo enkomponini equkethe izakhi zekhabhoni ukuze kufudunyezwe, ukuze izakhi zekhabhoni zingene ebusweni bebhola lensimbi, zandise ubulukhuni bayo kanye nokumelana nokuguguleka. Izinga lokushisa, isikhathi senqubo ye-carburizing kanye nokukhetha indlela yokulungisa i-carburizing kunemiphumela ebalulekile ekujiyeni nasekuqineni kwesendlalelo se-carburizing. Izinga lokushisa eliphakeme kakhulu noma isikhathi eside kakhulu kungaholela ekuqhekekeni, izinga lokushisa eliphansi kakhulu noma isikhathi esifushane kakhulu kuzothinta ikhwalithi kanye nomphumela wesendlalelo se-carburizing.
Umphumela wokwelashwa kokushisa kwamabhola ensimbi athwalayo uvame ukuhlolwa yizinkomba ezithile zokusebenza, njengokuqina, ukumelana nokuguguleka, ukuqina njalo njalo. Umphumela ofanele wokwelashwa kokushisa kufanele ube ukuqina okumaphakathi, ukumelana nokuguguleka okuhle, kanye nokucabangela ukuqina ukuqinisekisa impilo nokuthembeka kwebhola lensimbi elithwalayo ngesikhathi sokusetshenziswa.
Ukulungiswa nokulawulwa kwezinqubo nemiphumela yokwelashwa kokushisa kudinga imishini nobuchwepheshe obuthuthukisiwe, kanye nabasebenzi abanolwazi. Ekukhiqizeni kwangempela, kuyadingeka futhi ukulungisa nokulungisa ngokwezidingo ezithile zezinto zokwakha kanye nezinqubo ukuqinisekisa ukuthi ikhwalithi kanye nokusebenza kwamabhola ensimbi athwalayo kuhlangabezana nezindinganiso kanye nezidingo zamakhasimende.
