Isishwankathelo sokuBearing Steel

Ukuthwala intsimbi kusetyenziselwa ukwenza iibhola, ii-roller kunye namakhonkco okuthwala. Ukuthwala intsimbi kunobunzima obuphezulu kunye nobukhulu obufanayo, ukuxhathisa ukugqoka kunye nomda ophezulu we-elastic. Iimfuno zokufana kokwakheka kweekhemikhali, umxholo kunye nokuhanjiswa kwe-non-metallic inclusions, kunye nokuhanjiswa kwee-carbides zentsimbi ezithwele zingqongqo kakhulu. Ngomnye wemigangatho yentsimbi engqongqo kakhulu kuyo yonke imveliso yentsimbi.

Imigangatho yentsimbi yeentsimbi eziqhelekileyo ziphezulu carbon chromium ezithwele uthotho lwentsimbi, ezifana GCr15, Gcr15SiMn, njl Ukongeza, carburized bearing steels, ezifana 20CrNi2Mo, 20Cr2Ni4, njl, zingasetyenziswa ngokweemeko zokusebenza ezahlukeneyo, steel stainless steel 9 C, kunye ne-8 ephezulu njengentsimbi, i-bearing carburized steels, i-bearing carburized steels. iintsimbi, ezifana Cr4Mo4V, Cr15Mo4V2, njl.

Izinto eziphathekayo

Iimpawu ezibonakalayo zentsimbi yokuthwala ikakhulu ziquka i-microstructure, i-decarburized layer, inclusion non-metallic kunye ne-macrostructure. Ngokubanzi, iimveliso zihanjiswa nge-annealing eshushu yokuqengqeleka kunye ne-annealing ebandayo yokuzoba. Ubume bokuhanjiswa buya kuboniswa kwikhontrakthi. I-macrostructure yentsimbi kufuneka ingabikho kwi-shrinkage cavity, i-bubble subcutaneous, indawo emhlophe kunye ne-micro pore. I-porosity ephakathi kunye ne-porosity jikelele ayiyi kudlula i-grade 1.5, kwaye ukuhlukana akuyi kudlula i-grade 2. Isakhiwo se-annealed yensimbi siya kuhanjiswa ngokufanayo i-pearlite ecocekileyo. Ubunzulu bomaleko we-decarburization, inclusions non-metallic kunye nokungalingani kwe-carbide kuya kuhambelana nemigangatho yelizwe efanelekileyo.
