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 uqhutyelwa ngokuqhubekayo, kunokufunyanwa ukuba emva kwenani elithile leenguqu, utshintsho luya kuba malunga nokuphindaphindiweyo Ukuvela.Isalathiso sokulinganisa iqondo lolu tshintsho kukuchaneka komjikelezo wokujikeleza.Inani lohlaziyo olufunekayo kuqikelelo lokuphindaphinda utshintsho lumele "ixesha elilinganayo" lokuchaneka komjikelezo womjikelo.Ubungakanani benguqu kwi-quasi-period bukhulu, oko kukuthi, ukuchaneka kokujikeleza kwe-cyclic kubi..
Ukuba ukulayishwa kwangaphambili okufanelekileyo kusetyenziswe kwi-shaft ephambili, isantya sinyuka ngokuthe ngcembe ukuvala isantya sokusebenza ukuphumeza umphumo "wokugijima" wokuthwala, onokuphucula ukuchaneka kokujikeleza kwe-cyclic ye-shaft engundoqo.
2. Indlela yokuphucula ukuchaneka kokuthwala
Ulingo lwasefektri lwenziwe isixhobo esichanekileyo.I-shaft ephambili isetyenziswe iibheringi ze-6202 / P2, kodwa ukuchaneka kwayo kwakungenakukwazi ukuhlangabezana neemfuno.Emva kwexesha, ijenali yajiya kwaye kwenziwa umdyarho kuyo ukuze kuthathelwe indawo iringi yangaphakathi.Iqela ngalinye leebhola ezintathu lahlulwe lithuba eliphantse libe yi-120°.Ngenxa yokunciphisa umgangatho wokucubungula obunzima kunye nomgangatho ohambelanayo onzima, uphinda uphucule ukuqina kwenkqubo yokuthwala i-shaft, ngelixa iinqununu ezintathu ezinkulu kunye ezincinci ezintathu Ukusabalalisa ngokulinganayo okulinganayo kweebhola zensimbi kuphucula ukuchaneka kokujikeleza kwe-shaft. , ngaloo ndlela ihlangabezana neemfuno zokuchaneka kwesixhobo.
3. Indlela yokuqinisekisa ebanzi yokuchaneka kofakelo
Emva kokufaka i-angular yokudibanisa ibhola kwi-shaft engundoqo, ulandelelwano lokuqinisekisa ukuchaneka kofakelo 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 ungenelelo olulingeneyo, kwaye ungenelelo olulingeneyo yi-0~+4μm (0 kumthwalo okhanyayo kunye nokuchaneka okuphezulu) ukukhutshwa kwe-0 ~ + 6μm (kodwa ukukhutshwa kunokunyuswa xa ukuthwala kwisiphelo samahhala kusebenzisa i-angular contact ball bearing);impazamo yokujikeleza kwe-shaft kunye nomngxuma wezindlu ungaphantsi kwe-2μm, kunye nokuzala Ukuhambelana kobuso besiphelo se-spacer esisetyenzisiweyo kungaphantsi kwe-2 μm, ukuphuma kwesiphelo sangaphakathi segxalaba ukuya kwisiphelo sangaphandle sobuso. ngaphantsi kwe-2 μm;ukuphuma kwegxalaba lomngxuma wezindlu ezithwele ukuya kwi-axis ingaphantsi kwe-4 μm;ukuphuma kwesiphelo sangaphakathi se-shaft ephambili yokugubungela i-axis ingaphantsi kwe-4 μm.
(2) Ukufakwa kwe-front bearing of the fixed end on the shaft
Coca isiqhamo ngokucokisekileyo ngeparafini yokucoca ecocekileyo.Ukuthambisa igrisi, qala utofe isinyibilikisi se-organic esine-3% ukuya kwi-5% yegrisi kwi-bearing of degreasing kunye nokucoca, uze usebenzise umpu wegrisi ukugcwalisa umlinganiselo othile wegrisi kwibheringi (ibalelwa kwi-10% ukuya kwi-15% ukuthwala umthamo wendawo);ukutshisa i-bearing ukuphakamisa izinga lokushisa ngama-20 ukuya kuma-30 ° C, kwaye ufake i-bearing kwi-shaft end kunye ne-press hydraulic press;cinezela umkhono weadaptha kwi-shaft kwaye ucinezele ngokuchasene nobuso besiphelo sokuthwala kunye noxinzelelo olufanelekileyo ukuze wenze i-axially Positioning;moya ibhanti yebhalansi yasentwasahlobo kwiringi yangaphandle yebheringi, kwaye usebenzise indlela yokulinganisa itorque yokuqala ukuqinisekisa ukuba ukulayisha kwangaphambili okuchaziweyo kunotshintsho olukhulu (nokuba ukuthwala kuchanekile, kodwa ngenxa yokuguqulwa kokufaneleka. okanye ikheji, ukulayisha kwangaphambili kuya kutshintsha.
(3) Faka i-bearing-shaft assembly kumngxuma wesihlalo
Ukushisa umngxuma wesihlalo ukunyusa izinga lokushisa nge-20-30 ° C, kwaye ufake i-bearing-shaft assembly kwi-hong yesihlalo kunye noxinzelelo oluqhubekayo kunye nomnene;lungisa isigqubuthelo sangaphambili ukwenzela ukuba isixa sokuqina sekhava yangaphambili sibe yi-0.02-0.05 μm, uthabathe indawo engaphandle yesihlalo sokuthwala njengeBenchmark, ubeke intloko yegeyiji yokudayela ngokuchasene nomphezulu wejenali, ujikelezise i-shaft ukulinganisa. ukuphuma kwayo, kwaye impazamo iyafuneka ibe ngaphantsi kwe-10 μm;beka i-dial gauge kwi-shaft, yenza intloko ye-dial ithinte indawo yangaphakathi yendawo yokuhlala yangasemva, kwaye ujikeleze i-shaft Ukulinganisa i-coaxiality ye-coaxiality yangaphambili kunye nemigodi yezindlu yangasemva yesihlalo sokuthwala.
(4) Ngokukhethekileyo beka isiphelo sesiphelo esikhululekileyo kwindawo enokuphelisa ukutenxa, kwaye uyifake kwindawo yenkxaso yangasemva yendlu yokuthwala ukuphelisa ukuphambuka okujikelezayo kunye nokuphambuka kwe-coaxiality kangangoko kunokwenzeka.
Ufakelo lweebheringi eziphindwe kabini ezimfutshane ze-cylindrical roller kunye ne-tapered bore Xa ufaka i-NN3000K series double-row short cylindrical roller bearings with tapered bore, ingqwalasela kufuneka ihlawulwe kungqamaniso oluchanekileyo lwe-diameter yangaphakathi yebheringi kunye ne-taper ye-shaft, kwaye indlela yombala ingasetyenziselwa kwimeko yomthamo omncinci wokuvelisa.Ukulinganisa uqhagamshelwano, kodwa xa ibhetshi yemveliso inkulu, kungcono ukusebenzisa i-taper gauge echanekileyo yokulinganisa.
Xa ufaka ukuthwala kwi-shaft tapered, i-ring yangaphakathi kufuneka ilungiswe kwindawo efanelekileyo kwi-axial direction ukuze i-radial clearance isondele kwi-zero.
