Lapho ukuthwala kuzungeza ngaphansi komthwalo, ngenxa yokuthi indawo yomjaho wendandatho kanye nendawo egingqikayo yezinto eziginqikayo zihlala zingaphansi kwemithwalo eshintshanayo, ngisho noma izimo zokusebenzisa zivamile, umonakalo ofana nezinhlanzi (okuthiwa umonakalo wesikali sezinhlanzi) uzokwenzeka indawo yomjaho kanye nendawo egingqikayo ngenxa yokukhathala kwezinto.hlinza noma ukuxebula).Isamba senani lokuguquguquka ngaphambi kokulimala kokukhathala okugoqayo kubizwa ngokuthi "(ukukhathala)" impilo yokuthwala.Ngisho noma ama-bearings afana nesakhiwo, usayizi, impahla, indlela yokucubungula, njll., kusazoba nomehluko omkhulu empilweni (yokukhathala) yamamodeli okuthwala lapho ejikeleza ngaphansi kwezimo ezifanayo.Lokhu kungenxa yokuthi ukukhathala kwezinto ezibonakalayo ngokwako kuhlukile futhi kufanele kucatshangelwe ngokombono wezibalo.Ngakho-ke, lapho iqoqo lama-bearings afanayo lizungeziswa ngokuhlukana ngaphansi kwezimo ezifanayo, inani eliphelele lokujikeleza lapho u-90% wama-bearings engahlushwa ukulimala kokukhathala okubizwa ngokuthi "impilo eyisisekelo elinganiselwe yokuthwala" (okungukuthi, impilo lapho ukwethembeka kungu-90%).Uma uzungezisa ngesivinini esinqunyiwe, isikhathi esiphelele sokuzungezisa singavezwa.Kodwa-ke, emsebenzini wangempela, kungase kwenzeke umonakalo ngaphandle kokulimala kokukhathala.Lo monakalo ungagwenywa ngokukhetha okufanele, ukufakwa kanye nokugcotshwa.Isilinganiso somthwalo oguquguqukayo esiyisisekelo Isilinganiso somthwalo oguqukayo esiyisisekelo sibonisa amandla okuthwala ukumelana nokukhathala okuginqikayo (okungukuthi umthamo womthwalo).Kubhekiselwa kumthwalo weradial omsulwa wobukhulu obuthile kanye nesiqondiso (kuma-radial bearings).Indandatho yangaphakathi iyajikeleza futhi indandatho yangaphandle ilungisiwe (noma indandatho yangaphakathi Ngaphansi kwesimo sokujikeleza kwendandatho yangaphandle engaguquki), ukuphila okulinganiselwe okuyisisekelo ngaphansi kwalo mthwalo kungafinyelela ukuguqulwa kwesigidi esingu-1.Isilinganiso somthwalo oguquguqukayo esiyisisekelo se-radial bear sibizwa nge-radial basic dynamic load rating, evezwa yi-Cr, futhi inani layo lifakwe kuthebula losayizi wokuthwala (okuvezwa ngu-C kufomula elandelayo).

Ifomula yempilo yokulinganisa eyisisekelo (2) imelela ifomula yesilinganiso sempilo eyisisekelo yebheringi;ifomula (3) imele ifomula yempilo evezwa ngesikhathi lapho isivinini sokuthwala silungisiwe.(Inani eliphelele lama-revolutions) L10 = ( C )PP………………(2) (isikhathi) L10k =………………(3) 10660n ( ) CPP: ukuphila okulinganiselwe okuyisisekelo, ama-revolution angu-106: ukuphila okulinganiselwe okuyisisekelo, h: Umthwalo oguqukayo olinganayo, N{kgf}: Isilinganiso somthwalo esishintshashintshayo esiyisisekelo, N{kgf}: Isivinini sokuzungezisa, i-rpm: Inkomba yempilo L10pnCPL10k ibhola……………P=3 amarola……………Ngakho-ke P=310 , njengoba izimo zokusetshenziswa zebheringi, kucatshangwa ukuthi umthwalo oguqukayo olinganayo ungu-P futhi isivinini sokuzungezisa singu-n, khona-ke usayizi oyisisekelo olinganiselwe womthwalo oshukumisayo ongu-C webheringi edingekayo ukuhlangabezana nempilo yokuklama ingabalwa nge-Equation (4 ).Khetha ibheringi ehlangabezana nenani elingu-C kuthebula likasayizi wokuthwala ukuze unqume usayizi wokuthwala C=P(L10k Ifomula yokubala imi kanje: L10k=500fhf…………………(5) I-coefficient yempilo: fh=fn……………(I-6C P I-Speed ​​coefficient: = (0.03n) p…………………(7)-1fn=( )500x60n106Usebenzisa ishadi lokubala [isithombe esiyinkomba], fh, fn kanye ne-L10h kungatholakala kalula.Lapho ukhetha ama-bearings, impilo yokukhathala ithuthukiswa ngamabomu.Akunangqondo ukukhetha ama-bearings amakhulu namandla we-shaft, Ukuqina, ubukhulu bokufaka, njll. Akusekelwe empilweni yokukhathala kuphela.Amabheyiri asetshenziswa emishinini eyahlukene anokuphila kokuklama okulinganiselwe, okungukuthi, i-empirical fatigue life coefficient, ngokusekelwe ezimeni zokusetshenziswa.Sicela ubheke ithebula elingezansi.
