Nolosha daalka la qiimeeyay ee xadhkaha matoorka

Marka xamaasigu uu ku wareego culeyska, sababtoo ah marinka orodka ee giraanta iyo rogrogmada canaasiirta duuban ayaa si joogto ah loo saaraa culeysyo kala duwan, xitaa haddii xaaladaha adeegsigu ay caadi yihiin, dhaawac u eg kalluunka (oo loo yaqaan waxyeellada miisaanka kalluunka) ayaa ku dhici doona oogada dariiqa orodka iyo korka rogrogaya daalka alaabta awgeed.samee diirka ama diirka).Tirada guud ee kacaanka ka hor intaysan dhicin dhaawaca daalkan rogan waxa loo yaqaan "(daal)" nolosha xajmiga.Xataa haddii xajisyadu ay isku mid yihiin qaab-dhismeedka, cabbirka, agabka, habka farsamaynta, iwm., waxa weli jiri doona kala duwanaansho weyn oo xagga nolosha (daalka) ee moodooyinka wax-soo-saarka marka ay ku wareegayaan isla shuruudo isku mid ah.Tani waa sababta oo ah daalka maadiga laftiisa ayaa ah mid gaar ah oo waa in laga fiirsado dhinaca tirakoobka.Sidaa darteed, marka dufcad isku mid ah si gooni gooni ah loogu wareego isla shuruudo isku mid ah, tirada guud ee wareegyada kuwaas oo 90% ka mid ah tiirarka aysan ka soo gaarin dhaawac daal ah ayaa loo yaqaan "nolosha aasaasiga ah ee la qiimeeyey" (taas oo ah, nolosha lagu kalsoonaan karo waa 90%).Markaad ku wareegeyso xawaare go'an, wadarta wakhtiga wareegga sidoo kale waa la sheegi karaa.Si kastaba ha ahaatee, shaqada dhabta ah, ifafaale waxyeello aan ka ahayn daal rogan ayaa dhici karta.Waxyeelladan waxaa looga fogaan karaa xulashada saxda ah, rakibidda iyo saliidaynta.Qiimaynta dhaq-dhaqaaqa aasaasiga ah ee culeyska rarka fir-fircooniga ah ee aasaasiga ahi waxa ay tusinaysaa awoodda wax-qabadku u leeyahay in uu u adkaysto daalka rogaal-celinta (ie.Waxa ay tilmaamaysaa culayska shucaaca saafiga ah ee cabbirka iyo jihada cayiman (ee xajmiyada shucaaca).Giraanta gudaha ayaa wareegta oo giraanta dibadda ayaa go'an (ama giraanta gudaha iyadoo loo eegayo xaaladda wareegga wareegga dibadda ee go'an), nolosha aasaasiga ah ee lagu qiimeeyay culeyskan ayaa gaari kara 1 milyan oo kacdoon.Qiimaynta dhaq-dhaqaaqa aasaasiga ah ee radial bearing waxaa loo yaqaan radial aasaasiga ah rating load dynamic, oo uu muujiyay Cr, oo qiimihiisu waxaa la geliyey miiska cabbirka (oo lagu muujiyey C ee qaaciidada soo socota).

Qaacidada nolosha qiimaynta aasaasiga ah (2) waxa ay matalaysaa qaacidada xisaabinta nolosha ee qiimaynta aasaasiga ah;qaacidada (3) waxa ay matalaysaa qaacidada nolosha ee lagu sheegay wakhtiga marka xawaaruhu go'an yahay.(Tirada guud ee kacdoonnada) L10 = ( C ) PP…………(2) (waqtiga) L10k =…………3.…………P=3 rullaluistemadka…………P=310 sidaa darteed, sida shuruudaha isticmaalka ee xajinta, iyadoo loo maleynayo in culeyska dhaqdhaqaaqa u dhigma uu yahay P iyo xawaaruhu waa n, ka dibna culeyska dhaqdhaqaaqa aasaasiga ah ee lagu qiimeeyay C ee xajinta loo baahan yahay si loo daboolo nolosha naqshadeynta waxaa lagu xisaabin karaa isla'egta (4). ).Ka dooro jaanqaadka buuxinaya qiimaha C shaxda cabbirka cabbirka si aad u go'aamiso cabbirka cabbirka C=P(L10k Qaaciddada xisaabinta waa sida soo socota: L10k=500fhf……………….(5) Life coefficient: fh=fn…………(6C P Xawaaraha xawaaraha: = (0.03n) p……………….(7)-1fn=( )500x60n106Isticmaalka shaxda xisaabinta [sawirka tixraaca], fh, fn iyo L10h si fudud ayaa loo heli karaa.Marka la dooranayo xajmiyada, nolosha daalka si ula kac ah ayaa loo hagaajiyaa.Waa mid aan dhaqaale ahayn in la doorto xargaha waaweyn iyo xoogga usheeda dhexe, Adag, cabbirrada rakibaadda, iwm maaha mid ku salaysan nolosha daalka oo keliya.Gawaarida loo isticmaalo mishiinada kala duwan waxay leeyihiin nolol naqshadayn halbeeg ah, taas oo ah, isku-dhafka nolosha daalka dhabta ah, oo ku salaysan shuruudaha isticmaalka.Fadlan tixraac shaxda hoose.
