Ngaba kukho naziphi na iimfuno kwindawo yofakelo kunye nendawo yokufakela?

Ewe.Ukuba kukho iifayili zentsimbi, i-burrs, uthuli kunye nezinye izinto zangaphandle ezingena kwi-bearing, ukuthwala kuya kuvelisa ingxolo kunye nokungcangcazela ngexesha lokusebenza, kwaye kunokonakalisa i-raceways kunye nezinto ezijikelezayo.Ngoko ke, ngaphambi kokufaka i-bearing, kufuneka uqinisekise ukuba indawo yokunyuka kunye nendawo yokufakela icocekile.

Ngaba iibheringi kufuneka zicocwe phambi kofakelo?

Umphezulu wokuthwala ufakwe ngeoli echasene ne-rust.Kufuneka uyicoce ngononophelo ngepetroli ecocekileyo okanye i-kerosene, kwaye emva koko ufake igrisi yokuthambisa ecocekileyo, ekumgangatho ophezulu okanye enesantya esiphezulu kunye nobushushu obuphezulu phambi kokufakwa kunye nokusetyenziswa.Ukucoceka kunempembelelo enkulu ekuthwaleni ubomi kunye nokungcangcazela kunye nengxolo.Kodwa singathanda ukukukhumbuza ukuba iibheringi ezivaliweyo ngokupheleleyo akufuneki zicocwe kwaye zongezwe.

Indlela yokukhetha igrisi?

Ukuthambisa kunempembelelo ebaluleke kakhulu ekusebenzeni kunye nobomi beebheringi.Apha sikwazisa ngokufutshane imigaqo jikelele yokukhetha igrisi.Igrisi yenziwe nge-oyile yesiseko, i-thickener kunye ne-additives.Iipropati zeentlobo ezahlukeneyo zegrisi kunye neempawu ezahlukeneyo zohlobo olufanayo lwegrisi ziyahluka kakhulu, kwaye imida yokujikeleza evumelekileyo iyahluka.Qiniseka ukuba unikela ingqalelo xa ukhetha.Ukusebenza kwegrisi ikakhulu kunqunywe yioli yesiseko.Ngokuqhelekileyo, i-oyile yesiseko se-viscosity ephantsi ifanelekile kwiqondo lokushisa eliphantsi kunye nesantya esiphezulu, kwaye i-oyile yesiseko se-viscosity ephezulu ifanelekile kwiqondo lokushisa eliphezulu kunye nomthwalo ophezulu.I-thickener nayo inxulumene nokusebenza kwe-lubrication, kwaye ukunyanzeliswa kwamanzi kwe-thickener kumisela ukuxhathisa kwamanzi kwegrisi.Ngokomgaqo, iigrisi zeempawu ezahlukeneyo azikwazi ukuxutywa, kwaye iigrisi ezine-thickener efanayo ziya kuba nemiphumo emibi omnye komnye ngenxa yezongezo ezahlukeneyo.

Xa uthambisa iibheringi, ngaba kokukhona uthambisa igrisi kokukhona kungcono?

Xa uthambisa iibheringi, yimbono ephosakeleyo eqhelekileyo ukuba okukhona usebenzisa igrisi, kokukhona kungcono.Ukugqithiswa kwegrisi kwiibheringi kunye namagumbi okuzala kuya kubangela ukuxubana okugqithisileyo kwegrisi, okukhokelela kumaqondo obushushu aphezulu kakhulu.Ubungakanani be-lubricant ezaliswe kwi-bearing kufuneka ibe ngokwaneleyo ukuzalisa i-1/2 ukuya kwi-1/3 yendawo yangaphakathi yokuthwala, kwaye kufuneka iyancipha ukuya kwi-1/3 ngesivinini esikhulu.

Indlela yokufaka kunye nokuqhaqha?

Ngethuba lokufakela, musa ukubethelela ngokuthe ngqo ubuso bokuphela kunye nomgangatho ongagxininisi wokuthwala.Cinezela iibhloko, imikhono okanye ezinye izixhobo zokufakela (izixhobo) kufuneka zisetyenziswe ukugxininisa ngokulinganayo ukuthwala.Musa ukufaka ngokusebenzisa izinto eziqengqelekayo.Ukuba indawo yokunyuka ifakwe i-lubricated, ukufakela kuya kuhamba kakuhle.Ukuba ukuphazamiseka okufanelekileyo kukhulu, ukuthwala kufuneka kufakwe kwi-oyile yamaminerali kwaye kushushu kwi-80 ~ 90°C phambi kofakelo ngokukhawuleza.Lawula ngokungqongqo ubushushu be-oyile ukuba bungadluli kwi-100°C ukunqanda umphumo wokuthomalalisa ekunciphiseni ubulukhuni kunye nokuchaphazela ukubuyiswa kwe-dimensional.Xa uhlangabezana nobunzima kwi-disassembly, kucetyiswa ukuba usebenzise isixhobo sokuqhawula ukukhupha ngaphandle ngelixa ugalela ngokucophelela ioli eshushu kwindandatho yangaphakathi.Ubushushu buya kwandisa indandatho yangaphakathi yokuthwala, okwenza kube lula ukuwa.

Ngaba incinci i-radial clearance ye-bearing, ingcono?

Ayizizo zonke iibheringi ezifuna ubuncinci bemvume yokusebenza, kufuneka ukhethe imvume efanelekileyo ngokwemiqathango.Kumgangatho kazwelonke we-4604-93, ukuchithwa kwe-radial of rolling bearings ihlukaniswe ngamaqela amahlanu - iqela le-2, iqela le-0, iqela le-3, iqela le-4 kunye neqela lesi-5. Amaxabiso okucoca alandelelana ukusuka kwincinci ukuya enkulu, phakathi kweliphi iqela. 0 lusulelo olusemgangathweni.Iqela elisisiseko le-radial clearance lifanelekile kwiimeko zokusebenza ngokubanzi, amaqondo obushushu aqhelekileyo kunye nokuphazamiseka okuqhelekileyo okusetyenziswayo;iibheringi ezisebenza phantsi kweemeko ezikhethekileyo ezifana nobushushu obuphezulu, isantya esiphezulu, ingxolo ephantsi kunye nokukhuhlana okuphantsi kufuneka kusebenzise ukukhutshwa kweradial enkulu;iibheringi ezisebenza phantsi kweemeko ezikhethekileyo ezifana nobushushu obuphezulu, isantya esiphezulu, ingxolo ephantsi, ukukhuhlana okuphantsi, njl. njl.iibheringi ze-roller zinokugcina inani elincinci lemvume yokusebenza.Ukongeza, akukho mvumelwano yeebheringi ezahlukeneyo;ekugqibeleni, ukucocwa kokusebenza kokuthwala emva kokufakwa kuncinci kunokukhutshwa kokuqala ngaphambi kokufakwa, kuba ukuthwala kufuneka kuxhathise ukujikeleza komthwalo othile, kwaye kukho ukukhuhlana okubangelwa ukuthwala kunye nomthwalo.Isixa se-elastic deformation.
