Insimbi esetshenziswa ekukhiqizweni kwama-slewing bearings ihlukaniswe kakhulu ngezinhlobo ezine: 50Mn, 42CrMo, 20CrMnTi, kanye ne-GCr15SiMn. Ukuze kuhlaziywe ukumelana nokuguguleka kwamazinyo e-slewing bearings, kubalulekile ukuhlanganisa izici zezinto ezibonakalayo, izinqubo zokwelapha ukushisa, kanye nezimo zokusetshenziswa. Okulandelayo isifinyezo esisekelwe olwazini olufanele:

I-GCr15SiMn:Insimbi ephethe i-chromium enekhabhoni ephezulu, enobunzima obungu-60-64HRC, ukumelana okuhle kakhulu nokuguguleka, kanye nokumelana okungcono kokuguguleka kunensimbi ye-GCr15, efanelekela ukusebenza ngomthwalo omkhulu. Okuqukethwe okuphezulu kwekhabhoni (1.05%) kanye ne-chromium (1.5%) kwakha ama-carbide aqinile, anokumelana nokuguguleka okuphindwe kane kuno-20CrMnTi, afanelekela ukumelana nokuguguleka kanye nezimo zokusebenza zokumelana nokukhathala. Izinkambu zokusetshenziswa kwayo zifaka phakathi imishini yobunjiniyela, imiphini yokudlulisa izimoto, njll.

20CrMnTi:Lolu hlobo lwensimbi lungolwensimbi ene-carbon alloy ephansi, futhi ubulukhuni bayo bomphezulu buvame ukuthuthukiswa ngokwelashwa nge-carburizing kanye nokucima. Lungakha ungqimba lwe-carburizing lobunzima obukhulu ebusweni bezinyo, ngenkathi lugcina ukuqina okuhle namandla enkabeni. Ngemva kokwelashwa, ubulukhuni bomphezulu bungafinyelela ku-58-64HRC, futhi i-core igcina ukuqina okuhle namandla, ngakho-ke inokumelana okuhle nokuguguleka, ikakhulukazi efanelekela izimo zokusebenza ezisindayo, ezisheshayo noma ezithinta umthelela, njengezimbozo ze-slewing ezinsimbini, emishinini yezimayini nakwezinye izinkambu.

42CrMo:Njengoba ingeyensimbi ye-carbon alloy ephakathi nendawo, ivame ukuthola izakhiwo eziphezulu zemishini ngokuqeda nokulungisa (ukucima nokulungisa izinga lokushisa eliphezulu), ngokumelana nokuguguleka okumaphakathi, okufanele izimo ezinemithwalo emaphakathi futhi kungabi nomthelela omkhulu. Kodwa-ke, uma kuqhathaniswa nensimbi ye-carbon ephansi ephathwe nge-carburizing, ukumelana nokuguguleka kwayo kobuso kungaba ngaphansi. Ukuqina kokuguguleka namandla okukhathala e-42CrMo nakho kungcono, ngokuqina okuphezulu kobuso, okufanele izindawo zokuguguleka okuphezulu. I-42CrMo ifaneleka kakhulu ekukhiqizeniamabheringi okushelela,enamandla okukhiqiza okuhle kanye nokuqina, okungamelana kangcono nemithwalo ephezulu kanye nemithelela, futhi kufanelekile ekusebenzeni isikhathi eside kwemishini yokwakha. Lezi zinto, ngemva kokuqeda noma ukuqinisa, zingaqinisekisa ukusebenza okuzinzile kwamazinyo ngesikhathi sokusetshenziswa isikhathi eside, futhi zivame ukusetshenziswa njengezinsimbi zokushefa zemishini esindayo, ama-crane amakhulu, kanye neminye imishini.

50Mn:Lolu uhlobo lwensimbi ye-carbon manganese evame ukusetshenziswa ezicelweni ezidinga ukuqina okuphezulu kanye nokumelana nomthelela, kodwa ukumelana kwayo nokuguguleka kuyinto evamile futhi ingahlangabezana nezidingo zamandla kanye nokumelana nokuguguleka kwamazinyo ajwayelekile okuthwala izinsimbi. Insimbi ye-manganese ivame ukuphathwa ngokushisa (njengokucinywa) ukuze kwandiswe ubulukhuni bayo, kodwa ubulukhuni bayo bomphezulu buvame ukuba ngaphansi kobo be-20CrMnTi obuphathwe nge-carburizing, futhi kungenzeka ingasebenzi kahle njengensimbi ye-alloy ezindaweni zokugqoka imithwalo esindayo. Ubulukhuni bomphezulu wamazinyo bungafinyelela ku-50-60HRC, okwenza ifanelekele ama-bearing ezinsimbi ngaphansi kwemithwalo evamile kanye nezimo zokusebenza.

Izinga lokumelana nokuguguleka: Sekukonke, i-GCr15SiMn inokumelana okuhle kakhulu nokuguguleka, kuyilapho i-42CrMo kanye ne-20CrMnTi nazo zinokumelana okuhle nokuguguleka ngemva kokuguguleka nokucinywa. Ukumelana nokuguguleka kuncike engqimbeni yokuguguleka futhi kuvame ukuguguleka ngemva kokusetshenziswa isikhathi eside; Ukumelana nokuguguleka kwe-50Mn kubuthakathaka kakhulu. Lapho ukhetha, izimo ezithile zokusebenza (njengomthwalo, isivinini, imvamisa yomthelela) kanye nokwenza ngcono izinqubo zokwelapha ukushisa kufanele futhi kucatshangelwe. 

Ezingxenyeni ezibalulekile ezifana namazinyo okuthwala izinsimbi zokubopha, uma kokubili ukumelana nokuguguleka kanye nokumelana nokushayisana kudingeka kucatshangelwe, i-42CrMo ifaneleka kakhulu, enamandla alinganayo, ukuqina, kanye nokumelana nokuguguleka; Uma udinga ukulinganisela ukuqina okuphezulu kanye nokumelana nokushayisana, futhi ngaphansi kwezimo zokusebenza ezijwayelekile, i-50Mn nayo iyisinqumo esihle.

Ezisetshenzisweni ezisebenzayo, ukukhethwa kwezinto zamazinyo okuthwala izinsimbi kudinga ukucabangela ngokuphelele izici ezifana nezimo zokusebenza kwemishini, usayizi womthwalo, isivinini, indawo yokusebenza, kanye nobuchwepheshe bokwelashwa kokushisa ukuqinisekisa ukuthi ukusebenza kwamazinyo kuhlangabezana nezidingo zomklamo.
