Amagqabantshintshi ngeNsimbi yentsimbi/intonga
Ukuthwala intsimbi kusetyenziselwa ukwenza iibhola, ii-roller kunye neentsimbi zokuthwala. Ukuthwala kuthwala uxinzelelo olukhulu kunye nokukhuhlana xa usebenza, ngoko ke ukuthwala intsimbi kuyafuneka ukuba ube nobunzima obuphezulu kunye nobukhulu obufanayo, ukumelana nokunxiba 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 kuyo yonke imveliso yentsimbi. Ngo-1976, i-ISO, i-International Organisation for Standardization, yadibanisa amanqanaba entsimbi ngokubanzi kumgangatho wezizwe ngezizwe, kwaye yahlulahlula intsimbi yokuthwala ibe ziindidi ezine: intsimbi enentsimbi eqinileyo, intsimbi enentsimbi, intsimbi yokuthwala, kunye nobushushu obuphezulu. intsimbi, iyonke 17 amabakala entsimbi. Amanye amazwe ongeza udidi lwentsimbi yokuthwala okanye i-alloy ngeenjongo ezikhethekileyo. Indlela yokwahlula intsimbi efakwe kumgangatho waseChina ifana ne-ISO, ehambelana neendidi ezine eziphambili: i-carbon chromium ephezulu yensimbi, i-carburized bearing steel, i-stainless corrosion resistant steel bear, kunye ne-high-temperature bear steel steel.
Ukusetyenziswa kweNsimbi yeNsimbi yokuNxibelela / intonga
Ukuthwala intsimbi kusetyenziswa ikakhulu ukwenza umzimba oqengqelekayo kunye neringi yokuthwala. Ukuthwala intsimbi kuyadingeka ukuba ube nobunzima obuphezulu, ubunzima obufanayo, umda ophezulu we-elastic, amandla aphezulu okudinwa, ukuqina okufunekayo, ukuqina okuthile, kunye nokumelana nokunyuka kwe-corrosion kwi-agent ye-atmospheric smoothing, ngenxa yokuba ukuthwala kufuneka kube neempawu zobomi obude, ukuchaneka okuphezulu, ukushisa okuphantsi. , isantya esiphezulu, ukuqina okuphezulu, ingxolo ephantsi, ukuchasana nokugqoka okuphezulu, njl. Ukuze uhlangabezane neemfuno zokusebenza ezingentla apha, iimfuno kwi-chemical composition uniformity, i-non-metallic inclusion content kunye nohlobo, i-carbide particle size and dispersion, decarburization, njl. zokuthwala intsimbi zingqongqo. Ukuthwala intsimbi ngokuqhelekileyo kuphuhliswe kwindlela yomgangatho ophezulu, umsebenzi ophezulu kunye neentlobo ezininzi.
