Xa ukhetha i-bearing, kufuneka uqwalasele izinto ezininzi ezibalulekileyo.Inkalo yokuqala efanele iqwalaselwe ngumthwalo onokuwuthwala.Kukho iindidi ezimbini zemithwalo.
-Umthwalo we-axial : uhambelana ne-axis yokujikeleza
-Umthwalo weRadial: perpendicular to the axis of rotation
Uhlobo ngalunye lokuthwala luyilelwe ngokukodwa ukuxhasa imithwalo ye-axial okanye ye-radial.Ezinye iibheringi zinokuthwala zombini iindidi zemithwalo: sizibiza ngokuba yimithwalo edibeneyo.Umzekelo, ukuba ukuthwala kwakho kufuneka kuthwale umthwalo odibeneyo, sincoma ukuba ukhethe i-tapered roller bear.Ukuba ufuna i-bearing enokumelana nemithwalo ephezulu ye-radial, sincoma ukuthwala i-cylindrical roller.Kwelinye icala, ukuba ukuthwala kwakho kufuna ukuxhasa imithwalo elula, ukuthwala ibhola kunokwanela, njengoko ezi bheringi zihlala zingabizi kakhulu.
Isantya sokujikeleza yenye into ekufuneka iqwalaselwe.Ezinye iibheringi zinokumelana nezantya eziphezulu.Ngaloo ndlela, iibheringi ze-cylindrical roller kunye neebheringi zeenaliti ezinamakhagi zinesantya esiphezulu sokujikeleza xa kuthelekiswa neebheringi ezingenazo iikheji.Nangona kunjalo, ngamanye amaxesha izantya eziphezulu ziza ngeendleko zomthwalo.
Kufuneka kwakhona uqwalasele ukutenxa okunokwenzeka;ezinye iibheringi aziyilungelanga le nto, umzekelo iibheringi zebhola ezinemiqolo emibini.Ngoko ke, ingqalelo kufuneka ihlawulwe ekwakhiweni kwebherethi: iibheringi ezihlaziyiweyo kunye neebheringi eziziingqukuva zithande ukungahambi kakuhle.Sicebisa ukuba usebenzise iibheringi ezizilungelelanisayo ukulungelelanisa , ukuze ulungise ngokuzenzekelayo iziphene ezibangelwa kukugoba kweshaft okanye iimpazamo zokunyuka.
Kwakhona, iimeko zokusebenza zibaluleke kakhulu xa ukhetha ukuthwala okufanelekileyo.Ngoko ke, kuyimfuneko ukuhlalutya indawo yokusebenza apho ukuthwala kuya kusebenza.Iibheringi zakho zinokuba phantsi kongcoliseko olwahlukeneyo.Usetyenziso oluthile lungakhokelela kuphazamiso lwengxolo, ukothuka kunye/okanye ukungcangcazela.Ke ngoko, iibheringi zakho kufuneka zikwazi ukumelana nezi zothuso kwelinye icala kwaye zingabangeli ukuphazamiseka kwelinye.
Enye inkalo ebalulekileyo ekufuneka iqwalaselwe kukuthwala ubomi.Izinto ezahlukeneyo, ezifana nesantya okanye ukusetyenziswa ngokuphindaphindiweyo, zinokuchaphazela ukuthwala ubomi.
Ukukhetha inkqubo yokutywina kungundoqo ekuqinisekiseni ukuba iibheringi zakho zisebenza ngokuchanekileyo kwaye ixesha elide;ngoko ke, kubalulekile ukuqinisekisa ukuba iibheringi zisoloko zikhuselwe kakuhle kuzo naziphi na izinto ezingcolileyo kunye nezinto zangaphandle ezifana nothuli, amanzi, ulwelo oludliwayo okanye izithambiso ezisetyenzisiweyo.Olu khetho luxhomekeke kuhlobo lwe-lubricant, iimeko zokusingqongileyo (kwaye ngoko ke kunye nohlobo lokungcola), uxinzelelo lwe-fluid kunye nesantya.
Ukukunika isiqalo esihle, uxinzelelo lwe-fluid yinto ethatha isigqibo ekukhethweni kwenkqubo yokutywina.Ukuba uxinzelelo luphezulu ngokwaneleyo (umzekelo kuluhlu lwe-2-3 bar), isitywina somatshini sifanelekile.Ngaphandle koko, ukhetho luya kuhambelana ngokuthe ngqo nohlobo lwe-lubricant, igrisi okanye ioli.Ngokomzekelo, kwi-lubrication yegrisi, izisombululo eziqhelekileyo zezi: i-deflectors okanye i-gaskets, i-channel machined okanye encinci ene-grooves;kwimeko yokuthambisa ioli, inkqubo yokutywina iqhelekile
ekhatshwa yimijelo yokubuyisela ioyile.
Iimeko zokusetyenziswa ziyakuchaphazela ukhetho lwakho, ngakumbi xa uhlanganisa iibheringi.Kufuneka kuqwalaselwe kwakhona ukuqina kunye nokuchaneka okufunekayo xa i-bearing isetyenziswa.Kwezinye iimeko, ukulayishwa kwangaphambili kungasetyenziswa kwindibano yokuthwala ukunyusa ukuqina kwayo.Ukongeza, ukulayisha kwangaphambili kuya kuba nefuthe elihle ekuthwaleni ubomi kunye namanqanaba engxolo yenkqubo.Nceda uqaphele ukuba xa ukhetha ukulayisha kwangaphambili (i-radial okanye i-axial), kuya kufuneka ukwazi ukuqina kwawo onke amalungu ngesoftware okanye uvavanyo.
Phakathi kweekhrayitheriya zokukhetha kwakho, kuya kufuneka uthathele ingqalelo izinto ezifanelekileyo zokuthwala.Iibheringi zingenziwa ngentsimbi, iplastiki okanye i-ceramic.Izinto ezithwalayo zixhomekeke ekusetyenzisweni kwayo.Sincoma ukuba ukhethe ukuthwala eyona nto ixhathisayo kuxinzelelo.Nangona kunjalo, izinto ezisetyenzisiweyo ziyakuchaphazela ixabiso lokuthwala.
