Chitsulo chomwe chimagwiritsidwa ntchito popanga ma bearing odulidwa chimagawidwa m'mitundu inayi: 50Mn, 42CrMo, 20CrMnTi, ndi GCr15SiMn. Kuti muwunike momwe mano odulidwa amakanikira kutopa, ndikofunikira kuphatikiza mawonekedwe a zinthu, njira zochizira kutentha, ndi zochitika zogwiritsidwa ntchito. Izi ndi chidule chotengera mfundo zofunika:

GCr15SiMn:Chitsulo chokhala ndi chromium yambiri ya kaboni, cholimba cha 60-64HRC, cholimba kwambiri pakutha, komanso cholimba bwino pakutha kuposa chitsulo cha GCr15, choyenera kugwiritsidwa ntchito kwambiri. Mpweya wambiri wa kaboni (1.05%) ndi chromium (1.5%) umapanga ma carbide olimba, omwe amalimba nthawi zinayi kuposa 20CrMnTi, oyenera kugwiritsidwa ntchito molimba komanso molimba mtima. Magawo ake ogwiritsira ntchito akuphatikizapo makina aukadaulo, ma shaft otumizira magalimoto, ndi zina zotero.

20CrMnTi:Chitsulo chamtunduwu ndi cha chitsulo chopanda mpweya woipa, ndipo kuuma kwake pamwamba nthawi zambiri kumawonjezeka ndi chithandizo cha carburing ndi quenching. Chimatha kupanga gawo lolimba kwambiri la carburing pamwamba pa dzino, pomwe chimasunga kulimba ndi mphamvu mkati. Pambuyo pa chithandizo, kuuma pamwamba kumatha kufika 58-64HRC, ndipo pakati pake pamakhala kulimba ndi mphamvu, motero chimakhala ndi kukana kwabwino kwa kuwonongeka, makamaka koyenera kugwira ntchito molimbika, mwachangu kwambiri kapena mogunda, monga ma bearing ogwirira ntchito m'zitsulo, makina amigodi ndi madera ena.

42CrMo:Popeza ndi chitsulo chapakati cha carbon alloy, nthawi zambiri chimakhala ndi mphamvu zambiri zamakanika kudzera mu kuzimitsa ndi kutenthetsa (kuzimitsa ndi kutentha kwambiri), ndi kukana kuvala pang'ono, koyenera zochitika zokhala ndi katundu wochepa komanso osakhudzidwa kwambiri. Komabe, poyerekeza ndi chitsulo chotsika cha carbon chomwe chimathandizidwa ndi carburizing, kukana kwake kuvala pamwamba kungakhale kotsika. Kukhazikika kwa tempering ndi mphamvu ya kutopa ya 42CrMo ndizonso zabwino, zokhala ndi kuuma kwakukulu pamwamba, zoyenera malo owonongeka kwambiri. 42CrMo ndi yoyenera kwambiri popangamabeya odulira,yokhala ndi mphamvu zabwino zokolola komanso kulimba, zomwe zimatha kupirira katundu wambiri komanso kugundana, ndipo ndizoyenera kugwiritsa ntchito makina omanga kwa nthawi yayitali. Zipangizozi, zikatha kuzimitsa kapena kutenthetsa, zimatha kuonetsetsa kuti mano akugwira ntchito bwino nthawi yayitali, ndipo nthawi zambiri zimagwiritsidwa ntchito ngati mabeya odulira makina olemera, ma cranes akuluakulu, ndi zida zina.

50Mn:Uwu ndi mtundu wa chitsulo cha carbon manganese chomwe chimagwiritsidwa ntchito kwambiri m'magwiritsidwe ntchito omwe amafunikira kulimba kwambiri komanso kukana kugunda, koma kukana kwake kutopa ndi kwapakati ndipo kumatha kukwaniritsa zofunikira za mphamvu ndi kukana kuvala kwa mano ogwiritsira ntchito slewing. Chitsulo cha manganese nthawi zambiri chimatenthedwa (monga kuzimitsa) kuti chiwonjezere kuuma kwake, koma kuuma kwake pamwamba nthawi zambiri kumakhala kotsika kuposa kwa 20CrMnTi komwe kumathandizidwa ndi carburizing, ndipo sichingagwire ntchito bwino ngati chitsulo cha alloy m'malo ogwiritsidwa ntchito ndi katundu wolemera. Kuuma kwa pamwamba pa dzino kumatha kufika 50-60HRC, zomwe zimapangitsa kuti chikhale choyenera kugwiritsa ntchito slewing bearing pansi pa katundu wamba komanso mikhalidwe yogwirira ntchito.

Kusamvana ndi kuvala: Ponseponse, GCr15SiMn ili ndi kukana bwino kwambiri kuvala, pomwe 42CrMo ndi 20CrMnTi zimakhalanso ndi kukana bwino kuvala pambuyo pa carburing ndi kuzimitsa. Kukana kuvala kumadalira gawo la carburing ndipo kumatha kuvala pambuyo pa kugwiritsidwa ntchito kwa nthawi yayitali; Kukana kuvala kwa 50Mn ndi kofooka. Posankha, mikhalidwe yeniyeni yogwirira ntchito (monga katundu, liwiro, kuchuluka kwa kukhudzidwa) komanso kukonza njira zochizira kutentha ziyeneranso kuganiziridwa. 

Pazigawo zofunika monga mano odulira slewing, ngati zonse ziwiri ziyenera kuganiziridwa kuti zisawonongeke komanso zisawonongeke, 42CrMo ndi yoyenera kwambiri, yokhala ndi mphamvu yolinganiza, kulimba, komanso kukana kuwonongeka; Ngati mukufuna kulinganiza kulimba kwambiri komanso kukana kugunda, komanso pansi pa mikhalidwe yogwira ntchito bwino, 50Mn ndi chisankho chabwino.

Mu ntchito yeniyeni, kusankha zinthu za mano ogwirira ntchito kuyenera kuganizira mozama zinthu monga momwe zipangizo zimagwirira ntchito, kukula kwa katundu, liwiro, malo ogwirira ntchito, komanso kuphatikiza ukadaulo wothirira kutentha kuti zitsimikizire kuti magwiridwe antchito a manowo akukwaniritsa zofunikira pa kapangidwe kake.

Ngati muli ndi mafunso okhudza zinthu zomwe zimagwiritsidwa ntchito popangira slewing bearing, chonde lemberaniXuzhou Wanda Slewing Bearing Co., Ltd..
