Lapho ukhetha i-bearing, kufanele ucabangele izici ezimbalwa ezibalulekile.Isici sokuqala okufanele sicatshangelwe umthwalo ongawuthwala.Kunezinhlobo ezimbili zemithwalo.
-Umthwalo we-axial : uhambisana ne-eksisi yokujikeleza
-Umthwalo weRadial: perpendicular to the axis of rotation
Uhlobo ngalunye lokuthwala luklanyelwe ngokukhethekile ukusekela imithwalo ye-axial noma ye-radial.Amanye ama-bearings angakwazi ukuthwala zombili izinhlobo zemithwalo: sikubiza ngokuthi imithwalo ehlanganisiwe.Isibonelo, uma ukuthwala kwakho kufanele kuthwale umthwalo ohlangene, sincoma ukuthi ukhethe i-roller ene-tapered.Uma udinga i-bearing engakwazi ukumelana nemithwalo ephezulu ye-radial, sincoma i-cylindrical roller bear.Ngakolunye uhlangothi, uma ukuthwala kwakho kudinga ukusekela imithwalo elula, ukuthwala ibhola kungase kwanele, njengoba lawa mabhodi ngokuvamile eshibhile.
Isivinini sokujikeleza singesinye isici okufanele sicatshangelwe.Amanye ama-bearings angakwazi ukumelana nesivinini esiphezulu.Ngakho, ama-cylindrical roller bearings kanye ne-needle roller bearings ane-cages anesivinini esiphezulu sokujikeleza uma kuqhathaniswa nama-bearings ngaphandle kwamakheji.Nokho, ngezinye izikhathi isivinini esiphezulu siza ngezindleko zomthwalo.
Kudingeka futhi ucabange ngokuphambuka okungenzeka;amanye ama-bearings awafanele lokhu, isibonelo ama-double-row ball bearings.Ngakho-ke, ukunakwa kufanele kukhokhwe ekwakhiweni kwe-bearing: ama-bearings ahlehlisiwe kanye nama-spherical bearings athambekele ekungaqondisweni kahle okuthile.Sincoma ukuthi usebenzise ama-bearings aziqondanisayo ukuze ulungise , ukuze ulungise ngokuzenzakalela ububi bokuqondanisa obubangelwa ukugoba kwe-shaft noma amaphutha okukhweza.
Futhi, izimo zokusebenza zibaluleke kakhulu lapho ukhetha i-bearing efanelekile.Ngakho-ke, kuyadingeka ukuhlaziya indawo yokusebenza lapho ukuthwala kuzosebenza khona.Ama-bearings akho angase abe ngaphansi kokungcola okuhlukahlukene.Ezinye izinhlelo zokusebenza zingaholela ekuphazanyisweni komsindo, ukushaqeka kanye/noma ukudlidliza.Ngakho-ke, ama-bearings akho kufanele akwazi ukumelana nalokhu kushaqeka ngakolunye uhlangothi futhi angabangeli ukuphazamiseka ngakolunye.
Esinye isici esibalulekile okufanele sicatshangelwe ukuzala.Izinto ezihlukahlukene, njengejubane noma ukusetshenziswa okuphindaphindiwe, zingathinta impilo yokuzala.
Ukukhetha uhlelo lokuvala uphawu kuyisihluthulelo sokuqinisekisa ukuthi ama-bearings akho asebenza ngendlela efanele futhi isikhathi eside;ngakho-ke, kubalulekile ukuqinisekisa ukuthi ama-bearings ahlala evikelekile kahle kunoma yikuphi ukungcola nezici zangaphandle ezifana nothuli, amanzi, uketshezi olubolayo noma ngisho nezinto zokugcoba ezisetshenzisiwe.Lokhu kukhetha kuncike ohlotsheni lwe-lubricant, izimo zemvelo (ngakho-ke futhi ohlotsheni lokungcoliswa), ingcindezi yoketshezi kanye nesivinini.
Ukukunikeza indawo enhle yokuqala, ukucindezela koketshezi kuyisici esinqumayo ekukhetheni uhlelo lokuvala.Uma ingcindezi iphezulu ngokwanele (isb ebangeni le-2-3 bar), uphawu lomshini lulungile.Uma kungenjalo, ukukhetha kuzohlotshaniswa ngokuqondile nohlobo lwe-lubricant, amafutha noma amafutha.Isibonelo, ngokugcotshwa kwamafutha, izixazululo ezivame kakhulu yilezi: ama-deflectors noma ama-gaskets, iziteshi zomshini noma ezincane ezinemifula;endabeni yokugcoba kwamafutha, uhlelo lokuvala uphawu ngokuvamile
ephelezelwa grooves for uwoyela recovery.
Izimo zokusetshenziswa zizophinde zibe nomthelela ekukhetheni kwakho, ikakhulukazi lapho uhlanganisa ama-bearings.Kumelwe futhi kucatshangelwe ukuqina nokunemba okudingekayo lapho i-bearing isetshenziswa.Kwezinye izimo, ukulayisha kuqala kungasetshenziswa kumhlangano othwalayo ukuze kwandiswe ukuqina kwawo.Ngaphezu kwalokho, ukulayisha kuqala kuzoba nomthelela omuhle ekuthwaleni ukuphila namazinga omsindo wesistimu.Sicela uqaphele ukuthi uma ukhetha ukulayisha kuqala (i-radial noma i-axial), uzodinga ukwazi ukuqina kwazo zonke izingxenye ngesofthiwe noma ukuhlola.
Phakathi kwezinqubo zakho zokukhetha, kufanele futhi ucabangele izinto ezifanele zokuthwala.Ama-Bearings angenziwa ngensimbi, ipulasitiki noma i-ceramic.Izinto ezithwalayo zincike ekusetshenzisweni kwayo okuhlosiwe.Sincoma ukuthi ukhethe i-bearing elimelana kakhulu nokucindezelwa.Kodwa-ke, izinto ezisetshenzisiwe zizothinta intengo ye-bearing.
