Izakhiwo zensimbi yokuzala

Ngokusekelwe endaweni yokusebenza kanye nokuhlaziywa komonakalo weinsimbi ethwele, insimbi yokuthwala idinga ukuba nezinto ezilandelayo:

1. Amandla okukhathala okuthintana okuphezulu namandla acindezelayo;

2. Insimbi enensimbi kufanele ibe nobulukhuni obuphezulu nobufanayo ngemva kokwelashwa kokushisa (izidingo ezijwayelekile zobulukhuni bensimbi ye-HRC61~65);

3. Umkhawulo ophezulu wokunwebeka ukuvimbela ukuguqulwa kwepulasitiki ngokweqile kwensimbi enensimbi ngaphansi komthwalo omkhulu;

4. Ukuqina okuthile ukuvimbela ukuthwala umonakalo ngaphansi komthwalo womthelela;

5. Ukuzinza okuhle kwe-dimensional, vimbela ukuthwala isitoreji sesikhathi eside noma ukusetshenziswa ngenxa yokushintsha kosayizi kanye nokuncipha kokunemba;

6. Ukumelana nokugqwala okuthile, emkhathini kanye nokothambisa akumele kube lula ukugqwala noma ukugqwala, gcina ukucwebezela komhlaba;

7. Ukusebenza okuhle kwenqubo, njengokubandayo, ukusebenza okushisa okushisa, ukusebenza kokusika, ukusebenza kokugaya, ukusebenza kwenqubo yokushisa ukushisa nokunye, ukuze uvumelane nenani elikhulu, ukusebenza kahle okuphezulu, izidingo zokukhiqiza izinga eliphezulu. Kunezidingo ezahlukene zama-bearings ngaphansi kwezimo ezikhethekile zokusebenza. Njengokumelana nokushisa okuphezulu, ukumelana nokugqwala, ukumelana nomthelela, i-antimagnetic nokunye.

Ukuphila kokukhathala othintana naye kwama-bearings kuzwela ikakhulukazi ku-inhomogeneity yesakhiwo kanye nezakhiwo zensimbi. Ngakho-ke, kuhlongozwa uchungechunge lwezidingo zenhlangano esetshenziswayo kanye nenhlangano yokuqala. I-microstructure yensimbi enensimbi esesimweni sesevisi kufanele isatshalaliswe ngokulinganayo nge-carbide enhle ku-matrix ye-martensite epholile. I-microstructure enjalo inganikeza insimbi ethwele izakhiwo ezidingekayo. Kunezidingo ezimbili eziyinhloko zesakhiwo sokuqala: eyodwa ihlanzekile, ibhekisela kokuqukethwe kwezakhi zokungcola kanye nokufaka ensimbi ukuze kube kuncane; Okwesibili isakhiwo esifanayo, okusho ukuthi ama-non-metallic inclusions nama-carbides ensimbi kufanele ahlakazeke kahle futhi asakazwe ngokulinganayo. Ngakho-ke ukuhlanzeka kwensimbi kanye nokufana kwesakhiwo yizinkinga ezimbili eziyinhloko zekhwalithi ye-metallurgical yokuthwala insimbi.
