Xa ukuthwala kujikeleza phantsi komthwalo, ngenxa yokuba i-raceway surface yendandatho kunye ne-rolling surface of the rolling elements zihlala zixhomekeke kwimithwalo etshintshanayo, nokuba iimeko zokusetyenziswa ziqhelekileyo, umonakalo onjengentlanzi (obizwa ngokuba ngumonakalo wentlanzi) uya kwenzeka indawo yomdyarho kunye nomphezulu oqengqelekayo ngenxa yokudinwa kwezinto.ukuxobula okanye ukuxobula).Inani lilonke leenguqu phambi kokuba kwenzeke umonakalo wokudinwa okuqengqelekayo kubizwa ngokuba bubomi “(ukudinwa)” bebheringi.Nangona iibheringi zifana nesakhiwo, ubukhulu, izinto eziphathekayo, indlela yokucubungula, njl., kuya kubakho ukungafani okukhulu (ukukhathala) ubomi beemodeli zokuthwala xa ujikeleza phantsi kweemeko ezifanayo.Oku kungenxa yokuba ukudinwa kwezinto ngokwako kucacile kwaye kufuneka kuthathelwe ingqalelo ngokweenkcukacha-manani.Ke ngoko, xa ibhetshi yeebheringi ezifanayo zijikeleziswa ngokwahlukileyo phantsi kweemeko ezifanayo, inani elipheleleyo lokujikeleza apho i-90% yeebheringi ingakhathazwa kumonakalo wokudinwa okuqengqelekayo kubizwa ngokuba "yisiseko sobomi bokuthwala" (oko kukuthi, ubomi apho ukuthembeka yi-90%).Xa ujikeleza ngesantya esisisigxina, ixesha elipheleleyo lokujikeleza lingabonakaliswa.Nangona kunjalo, kumsebenzi wokwenyani, umonakalo owenzekayo ngaphandle komonakalo wokudinwa unokwenzeka.Lo monakalo unokuphetshwa ngokukhetha okufanelekileyo kokuthwala, ukufakwa kunye nokuthambisa.Umlinganiselo womthwalo oguquguqukayo osisiseko wobungakanani bomthwalo oguqukayo ubonisa ukukwazi kwesixhobo ukumelana nokudinwa okuqengqelekayo (okt umthamo womthwalo).Ibhekisela kumthwalo ococekileyo we-radial wobukhulu obuthile kunye nolwalathiso (kwii-radial bearings).I-ring yangaphakathi ijikeleza kwaye i-ring yangaphandle igxininiswe (okanye i-ring yangaphakathi Ngaphantsi kwemeko esisigxina yokujikeleza kwendandatho yangaphandle), ubomi obuyisiseko obulinganiselwe phantsi kwalo mthwalo bunokufikelela kwi-1 yezigidi zeenguqu.Umlinganiselo osisiseko womthwalo we-radial ubizwa ngokuba yi-radial basic dynamic load rating, echazwe yi-Cr, kwaye ixabiso layo lifakwe kwi-bearing size table (echazwe ngu-C kule fomyula ilandelayo).

Ifomyula yobomi bokulinganisa (2) imele isiseko sefomula yokubala ubomi bokulinganisa;ifomula (3) imele ifomula yobomi echazwe ngexesha xa isantya sokuthwala silungisiwe.(Inani elipheleleyo leenguqu) L10 = ( C ) PP………………(2) (ixesha) L10k =………………3……………P=3 ukuthwala irola……………P=310 ke ngoko, njengemiqathango yokusetyenziswa kokuthwala, kucingwa ukuba umthwalo olinganayo oguquguqukayo yi-P kunye nesantya sokujikeleza ngu-n, ngoko ke isiseko esilinganiselweyo somthwalo oguqukayo we-C wokuthwala ofunekayo ukuhlangabezana nobomi bokuyila singabalwa nge-Equation (4) ).Khetha uhlobo oludibana nexabiso C ukusuka kwitheyibhile yobungakanani bokuthwala ukumisela ubungakanani bokuthwala C=P(L10k Ifomula yokubala ngolu hlobo lulandelayo: L10k=500fhf…………………(5) Umlinganiso wobomi: fh=fn……………(I-6C P i-Speed ​​coefficient: = (0.03n) p…………………(7)-1fn=( )500x60n106Usebenzisa itshathi yokubala [umfanekiso wereferensi], fh, fn kunye ne-L10h inokufumaneka lula.Xa ukhetha iibheringi, ubomi bokudinwa buphuculwa ngabom.Akunamali ukukhetha iibheringi ezinkulu kunye namandla e-shaft, Ukuqina, imilinganiselo yokufakela, njl. Akufuneki ukuba kusekelwe kubomi bokukhathala kuphela.Iibheringi ezisetyenziswa koomatshini abahlukeneyo zinobomi boyilo lokuyila, oko kukuthi, ubomi bokudinwa okubonakalayo, ngokusekwe phantsi kweemeko zokusetyenziswa.Nceda ujonge le theyibhile ingezantsi.
