Yazisa ukuchaneka kweebheringi ezichanekileyo emva kokufakwa
1. Indlela yokuphucula ukuchaneka
Emva kokuba ukuthwala kufakwe kwi-injini eyintloko, ukuba ukuchithwa kwe-radial ye-shaft engundoqo kulinganiswa, kunokufunyanwa ukuba ixabiso elilinganisiweyo le-revolution nganye linotshintsho oluthile;xa umlinganiselo oqhubekayo wenziwa, kunokufunyanwa ukuba emva kwenani elithile lohlaziyo, olu tshintsho luya phantse ukuphinda.Vela.Isalathiso sokulinganisa iqondo lolu tshintsho kukuchaneka komjikelezo wokujikeleza.Inani leenguqu ezifunekayo ukuze utshintsho lubonakale malunga nophinda-phindo lumele "ixesha le-quasi" lokuchaneka komjikelezo womjikelo.Ubungakanani benguqu kwi-quasi-period bukhulu, nto leyo engalunganga ukuchaneka kokujikeleza kwebhayisikile..Ukuba ukulayisha kwangaphambili okufanelekileyo kusetyenziswe kwi-shaft ephambili, isantya sinyuka ngokuthe ngcembe ukuvala isantya sokusebenza, ukwenzela ukuba kuphunyezwe umphumo "wokugijima" wokuthwala, onokuphucula ukuchaneka kokujikeleza kwe-cyclic ye-shaft engundoqo.
2. Indlela yokuphucula ukuchaneka kokuthwala
Ulingo lwefektri luvelisa izixhobo ezichanekileyo, i-shaft ephambili isebenzisa uhlobo lwe-6202/P2 iibheringi kwaye ukuchaneka kwayo kusenakukwazi ukuhlangabezana neemfuno, emva koko jiya ijenali kwaye wenze umdyarho kuyo ukuze ubuyisele umsesane ongaphakathi, kwaye ulinganise ukuxinana kwentsimbi. Ibhola, ngokobungakanani Iqela ngalinye leebhola ezintathu zentsimbi lahlulwe lithuba eliphantse libe yi-120 °.Ngenxa yokuncitshiswa komgangatho womatshini onzima kunye nomgangatho ohambelanayo onzima, ukuqina kwenkqubo yokuthwala i-shaft kuphuculwe, kwaye iibhola ezintathu ezinkulu kunye neebhola ezintathu ezincinci zi Ukusabalalisa okuphantse kulingane kweebhola zentsimbi kuphucula ukuchaneka kokujikeleza. i-shaft, ngaloo ndlela ihlangabezana neemfuno zokuchaneka kwesixhobo.
3. Indlela yokuqinisekisa ebanzi yokuchaneka kofakelo
Emva kokuba i-angular yokudibanisa ibhola ifakwe kwi-spindle, ulandelelwano lokujonga ukuchaneka kofakelo luhamba ngolu hlobo lulandelayo (ukuthatha i-lathe eqhelekileyo kunye nobubanzi be-shaft ye-60-100mm njengomzekelo):
(1) Ukulinganisa ubungakanani be-shaft kunye nomngxuma wesihlalo sokuthwala ukugqiba ukuchaneka okuhambelanayo kwebheringi.Iimfuno ezihambelanayo zezi zilandelayo: Iringi yangaphakathi kunye neshafti zamkela ukungenelela kongenelelo, kwaye isixa sophazamiseko yi-0~+4μm (0 yomthwalo olula kunye nokuchaneka okuphezulu); kunye nesixa sokucocwa ngu-0 ~ + 6μm (kodwa xa i-earing end bearing isebenzisa i-angular contact ball bearing, imvume inokunyuswa kwakhona);impazamo yokujikeleza komhlaba phakathi kwe-shaft kunye nomngxuma wesihlalo ungaphantsi kwe-2μm, ukuthwala Ukuhambelana kobuso besiphelo se-spacer esetyenzisiweyo kungaphantsi kwe-2μm, ukuphuma kwesiphelo sangaphakathi segxalaba le-shaft elijongene nobuso besiphelo sangaphandle singaphantsi kwe-2μm. ;ukukhutshwa komngxuma wesihlalo sokuthwala igxalaba ukuya kwi-axis ingaphantsi kwe-4μm;ukuphuma kwesiphelo sangaphakathi sesigqubuthelo sangaphambili se-spindle esijongene ne-axis singaphantsi kwe-4μm.
(2) Ufakelo lwebherethi yangaphambili kwisiphelo esimisiweyo kwi-shaft, coca ngokucokisekileyo ukuthwala nge-kerosene yokucoca ecocekileyo.Ukuthambisa igrisi, qala ngokutofa isinyibilikisi se-organic esine-3% ukuya kwi-5% yegrisi kwi-bearing ye-degreasing kunye nokucoca, uze usebenzise I-oil gun igcwalisa inani elithile legrisi kwi-bearing (ibali-10% ukuya kwi-15% yokuthwala umthamo wendawo);ukutshisa ukuthwala ukuphakamisa izinga lokushisa kwi-20 ukuya kwi-30 ° C, kwaye ufake i-bearing kwi-shaft end kunye ne-press hydraulic press;cinezela umkhono we-adaptha kwi-shaft Kwaye ucinezele isiphelo sobuso bebheringi kunye noxinzelelo olufanelekileyo ukuze wenze i-axially positioning;qengqeleka ibhanti yesikali sasentwasahlobo kwiringi yangaphandle yokuthwala, kwaye usebenzise indlela yokulinganisa itorque yokuqala ukujonga ukuba ukulayisha kwangaphambili okuchaziweyo kunotshintsho olukhulu (nokuba ukuthwala kuchanekile)., kodwa ukulayishwa kwangaphambili kunokutshintsha ngenxa yokuguqulwa kokulingana okanye ikheji).
(3) Beka i-bearing-shaft assembly emngxunyeni wesihlalo, fudumeza umngxuma wesitulo ukunyusa iqondo lobushushu ngama-20-30°C, kwaye usebenzise uxinzelelo oluqhubekayo oluthambileyo ukufaka indibano ye-bearing-shaft kumngxuma wesihlalo;lungisa isiciko sangaphambili ukwenza isiciko sangaphambili siqine Isixa esiqinileyo yi-0.02 ~ 0.05μm, ngokusekwe kubuso besiphelo sangaphandle sesihlalo esiphetheyo, intloko yesalathisi sokudayela ichasene nomphezulu wejenali, kwaye i-shaft ijikeleziswa ukuya. ukulinganisa ukuphuma, kwaye impazamo iyadingeka ukuba ibe ngaphantsi kwe-10μm;isalathisi sokudayela sibekwe kwi-shaft., intloko ye-gauge ichasene nomphezulu ongaphakathi womngxuma wesihlalo esingasemva, kwaye i-shaft ijikelezwe ukulinganisa i-coaxiality ye-coaxiality yezihlalo zangaphambili kunye nezitulo zangasemva zesihlalo sokuthwala.
