Emva kokuba i-bearing iqhube ixesha elide, akunakuphepheka ukuba kuya kubakho imfuneko yokugcinwa okanye umonakalo kunye nokutshintshwa. Kwiintsuku zokuqala zophuhliso loshishino loomatshini, bekufuneka ukuba kubekho ukuthandwa ngakumbi kolwazi lobuchwephesha kunye nokwazisa ngeenkqubo zokusebenza ezikhuselekileyo. Namhlanje, siza kuthetha kuphela malunga nokuchithwa kweebheringi.
Kuqhelekile ukuba abanye abantu baqhawule iibheringi ngokukhawuleza ngaphandle kokuzihlola kakuhle. Nangona oku kungabonakala kusebenza ngokufanelekileyo, kubalulekile ukuqwalasela ukuba awukho wonke umonakalo obonakalayo kwindawo yokuthwala. Kusenokubakho umonakalo ngaphakathi ongenakubonwa. Ngaphezu koko, ukuthwala intsimbi kunzima kwaye kubuhlungu, oku kuthetha ukuba inokuqhekeka phantsi kobunzima bayo, okukhokelela kwimiphumo emibi.
Kubalulekile ukulandela iinkqubo zenzululwazi kunye nokusebenzisa izixhobo ezifanelekileyo xa ufaka okanye ukhulula i-bearing ukuphepha nawuphi na umonakalo onokuthi ubekho. Ukuchithwa ngokuchanekileyo kunye nokukhawuleza kweebheringi kufuna izakhono kunye nolwazi, oluxutyushwa ngokubanzi kweli nqaku.
Ukhuseleko kuqala
Ukhuseleko kufuneka luhlale luyiyona nto iphambili kuyo nayiphi na imisebenzi, kuquka ukuthwala ukuchithwa. Iibheringi zinokuba namava okuguga kunye nokukrazuka ukuya esiphelweni sobomi bawo. Kwiimeko ezinjalo, ukuba inkqubo ye-disassembly ayiqhutywa ngokuchanekileyo kwaye kusetyenziswe ubuninzi obugqithisileyo bamandla angaphandle, kukho ithuba eliphezulu lokuqhawula. Oku kunokubangela ukuba iingceba zentsimbi ziphaphazele ngaphandle, nto leyo eyenza ingozi enkulu yokhuseleko. Ngoko ke, kucetyiswa kakhulu ukusebenzisa ingubo yokukhusela ngelixa udibanisa i-bearing ukuqinisekisa ukusebenza okukhuselekileyo.
Ukuhlelwa kwe-bearing disassembly
Xa imilinganiselo yokuxhasa iqulunqwe ngokuchanekileyo, iibheringi ezinee-clean fits zingasuswa ngokulungelelanisa iibheringi, nje ngokuba zingekho i-deformed okanye i-rust ngenxa yokusetyenziswa ngokugqithiseleyo kwaye ibambelele kwiindawo ezihambelanayo. Ukuchithwa okunengqiqo kweebheringi phantsi kweemeko ezifanelekileyo zokuphazamiseka kungundoqo wokuthwala iteknoloji ye-disassembly. I-Bearing interference fit yahlulwe yaba ziindidi ezimbini: ukuphazamiseka kweringi yangaphakathi kunye nokuphazamiseka kweringi yangaphandle. Kwimihlathi elandelayo, siza kuxubusha ezi ntlobo zimbini ngokwahlukeneyo.
1. Ukuphazamiseka kwendandatho yangaphakathi yebheringi kunye nococeko olufanelekileyo lwendandatho yangaphandle
1. I-shaft ye-cylindrical
Ukuthwala i-disassembly kufuna ukusetyenziswa kwezixhobo ezithile. Idonsa idla ngokusetyenziselwa iibheringi ezincinci. Aba batsali beza kwiindidi ezimbini - i- two-claw kunye ne-three-claw, zombini inokuthungwa okanye i-hydraulic.
Isixhobo esiqhelekileyo sisitsali somsonto, esisebenza ngokulungelelanisa isikrufu esiseziko kunye nomngxuma osembindini we-shaft, ukufaka igrisi kumngxuma osembindini we-shaft, kwaye ke ukuhuka ihuku kwisiphelo sobuso beringi yangaphakathi yebheringi. Nje ukuba ihuku ibekwe kwindawo yayo, i-wrench isetyenziselwa ukujika intonga esembindini, ethi ikhuphe intonga.
Ngakolunye uhlangothi, i-hydraulic puller isebenzisa i-hydraulic device endaweni yomsonto. Xa ucinezelekile, ipiston embindini iyanda, kwaye ukuthwala kutsalwa ngokuqhubekayo. Iyakhawuleza kunomtsala wentambo yemveli, kwaye isixhobo soxinzelelo lomoya sinokuhlehla ngokukhawuleza.
Kwezinye iimeko, akukho ndawo yeenzipho zotsalo wemveli phakathi kobuso bokuphela kweringi yangaphakathi yokuthwala kunye namanye amacandelo. Kwiimeko ezinjalo, i-splint-piece-piece ingasetyenziswa. Unokukhetha ubungakanani obufanelekileyo be-splint kwaye uyikhuphe ngokwahlukileyo ngokufaka uxinzelelo. Iinxalenye zeplywood zingenziwa zibe mncinci ukuze zikwazi ukungena kwiindawo ezimxinwa.
Xa ibhetshi enkulu yeebheringi ezinobungakanani obuncinci kufuneka idityaniswe, isixhobo sokusebenza samanzi esikhawulezayo sinokusetyenziswa (njengoko kubonisiwe ngezantsi).
▲Nxiba ngokukhawuleza isixhobo sokwenziwa kolwelo olwenziwa ngamanzi
Ukutshatyalaliswa kweebheringi ezidityanisiweyo kwii-axles zesithuthi sikaloliwe, kukwakho nezixhobo ezikhethekileyo ze-disassembly mobile.
▲Isixhobo sokuqhaqha esiphathwayo
Ukuba ubungakanani bebhere bukhulu, ngoko kuya kufuneka amandla amaninzi ukuyichitha. Kwiimeko ezinjalo, abatsali ngokubanzi abayi kusebenza, kwaye umntu uya kufuna ukuyila izixhobo ezikhethekileyo zokuqhawula. Ukuqikelela amandla amancinci afunekayo ekuqhaqhekeni, ungabhekisa kumandla ofakelo afunekayo ukuze uthwale ukoyisa ukungenelela kokuphazamiseka. Ifomula yokubala imi ngolu hlobo lulandelayo:
F=0.5 *π *u*W*δ* E*(1-(d/d0)2)
F = Ukunyanzeliswa (N)
μ = i-friction coefficient phakathi kweringi yangaphakathi kunye ne-shaft, ngokubanzi malunga ne-0.2
W = ububanzi beringi yangaphakathi (m)
δ = ungenelelo olulinganayo (m)
E = Imodyuli yabaselula 2.07×1011 (Pa)
d = ethwele idiameter yangaphakathi (mm)
d0=idayamitha ephakathi yendlela yomdyarho yangaphandle yeringi yangaphakathi (mm)
π= 3.14
Xa amandla afunekayo ukuqhawula i-bearing inkulu kakhulu kwiindlela eziqhelekileyo kunye neengozi zokonakalisa ukuthwala, umngxuma weoli udla ngokuyilwa ekupheleni kwe-shaft. Lo mngxunya we-oyile udlulela kwindawo yokuthwala kwaye emva koko ungene kwi-shaft surface radially. I-groove ye-annular yongezwa, kwaye ipompo ye-hydraulic isetyenziselwa ukucinezela isiphelo se-shaft ukwandisa i-ring yangaphakathi ngexesha lokuchithwa, ukunciphisa amandla afunekayo ukuchithwa.
Ukuba ukuthwala kukhulu kakhulu ukuba kungadityaniswa ngokutsala nzima, ngoko ke kufuneka kusetyenziswe indlela yokufudumeza yokufudumala. Kule ndlela, izixhobo ezipheleleyo ezifana neejacks, i-gauge gauges, i-spreaders, njl., kufuneka zilungiselelwe ukusebenza. Indlela ibandakanya ukufudumeza i-coil ngqo kwi-raceway ye-ring yangaphakathi ukuze ikhulise, okwenza kube lula ukukhupha i-bearing. Le ndlela yokufudumala ifanayo ingasetyenziselwa iibheringi ze-cylindrical kunye neerola ezihlukeneyo. Ngokusebenzisa le ndlela, ukuthwala kunokutshatyalaliswa ngaphandle kokubangela umonakalo.

2. Ishafti enetapered
Xa uqhawula ibherethi enetapered, isiphelo esikhulu sobuso beringi yangaphakathi kufuneka ifudunyezwe kuba indawo yayo inkulu kakhulu kunobunye isiphelo. I-coil flexible medium frequency induction heater isetyenziselwa ukufudumeza iringi yangaphakathi ngokukhawuleza, ukudala umahluko wobushushu kunye ne-shaft kunye nokuvumela ukuchithwa. Njengoko i-tapered bearings isetyenziswe ngababini, emva kokususa indandatho yangaphakathi, enye iya kubonakaliswa ngokushisa. Ukuba indawo enkulu yokuphela ayikwazi ukufudumeza, i-cage kufuneka ibhujiswe, i-roller isuswe, kwaye umzimba wendandatho yangaphakathi uvele. Ikhoyili inokubekwa ngokuthe ngqo kwibala lokubaleka ukufudumeza.
▲ I-coil eguquguqukayo ephakathi kwe-frequency induction heater
Ubushushu bokufudumala bokufudumala akufuneki budlule kwi-120 degrees Celsius kuba ukuthwala ukuchithwa kufuna ukuhluka kobushushu obukhawulezayo kunye nenkqubo yokusebenza, kungekhona ubushushu. Ukuba ubushushu be-ambient buphezulu kakhulu, ukuphazamiseka kukhulu kakhulu, kwaye ukuhluka kweqondo lokushisa akwanelanga, i-ice eyomileyo (i-carbon dioxide eqinile) ingasetyenziselwa njengendlela yokuncedisa. Umkhenkce owomileyo unokubekwa kudonga lwangaphakathi lomngxuma weshafti ukunciphisa ngokukhawuleza iqondo lobushushu le-shaft (ngokuqhelekileyo kubukhulu obunjalo.iindawo zecnc), ngokwandisa umahluko wobushushu.
Ukutshatyalaliswa kweebheringi ze-tapered bore, musa ukususa ngokupheleleyo i-nati ebambezelayo okanye indlela ekupheleni kwe-shaft ngaphambi kokuba i-disassembly. Yikhulule kuphela ukunqanda ukuthwala iingozi eziwayo.
Ukuchithwa kwee-shafts ezinkulu ezinobungakanani obukhulu kudinga ukusetyenziswa kwemingxuma yeoli ye-disassembly. Ukuthatha i-rolling mill's four-row tapered bearing TQIT kunye ne-tapered bore njengomzekelo, i-ring yangaphakathi ye-bearing yahlulwe ibe ngamacandelo amathathu: amakhonkco amabini angaphakathi angaphakathi kunye ne-ring yangaphakathi ephindwe kabini phakathi. Kukho imingxuma emithathu yeoli ekupheleni komqulu, ehambelana namanqaku 1 kunye ne-2,3, apho enye ihambelana nendandatho yangaphakathi yangaphandle, ezimbini zihambelana nekhonkco elingaphakathi eliphindwe kabini phakathi, kwaye ezintathu zihambelana nomsesane wangaphakathi wangaphakathi. ubukhulu becala. Xa uqhaqha, qhaqha ngokulandelelana kwamanani e-serial kwaye ucinezele imingxuma 1, 2, kunye ne-3, ngokulandelanayo. Emva kokuba konke kugqityiwe, xa ukuthwala kunokuphakanyiswa ngelixa uqhuba, susa i-hinge ring ekupheleni kwe-shaft kwaye udibanise ukuthwala.
Ukuba ukuthwala kuya kusetyenziswa kwakhona emva kokuchithwa, imikhosi eyenziwa ngexesha lokuchithwa akufanele idluliselwe kwizinto ezijikelezayo. Kwiibheringi ezihlukeneyo, i-ring ring, kunye ne-rolling element cage assembly, inokutshatyalaliswa ngokwahlukileyo kwenye i-ring bear. Xa uchitha iibheringi ezingenakuhlukaniswa, kufuneka uqale ususe amakhonkco okuthwala kunye ne-clearance fit. Ukuqhawula iibheringi kunye nokulingana kokuphazamiseka, kufuneka usebenzise izixhobo ezahlukeneyo ngokohlobo lwazo, ubungakanani kunye nendlela efanelekileyo.
