Ama-ringing bearings afakwe izigxivizo ze-cor kuzo zombili iziphetho.Ngesembozo sothuli kanye nesigxivizo, ukusebenza okubili okuhlukene, eyodwa iwubufakazi bothuli, enye ivaliwe.Seal iwukuba ukwenza eziveza amafutha yangaphakathi (amafutha) ekusetshenzisweni inqubo akalahlekelwa, ngaphandle amafutha angcolile akulula ukungena, ukuqinisekisa ukuthi ukuthwala esimweni lubricated;i-dustp roof iwukuvikela ingaphandle le-bearings othulini noma emagesini ayingozi angene emgodini wokuthwala, ukuze kuvinjelwe ukuthwala umonakalo.
Isibhakela.ukuthwala nokubeka uphawu
Eminyakeni yamuva, ama-bearings afakwe izinto zokuvala uphawu.Esikhathini esidlule, ama-bearings avuliwe.Ukuze kuqinisekiswe ukugcotshwa nokufakwa kothuli kwama-bearings, amadivaysi okuvala afakwe kuma-shafts emaphethelweni womabili ama-bearings.Ngokuthuthuka kwezimboni, ikakhulukazi imboni yokudla, ukuthandwa kwemishini yesimanje yasehhovisi kanye nemishini yasendlini kudinga ukwakhiwa kwemishini ehlangene ukuze kuncishiswe isisindo futhi kuvinjwe ukuvuza kwezimpawu ezine-roller ezingaxhunywanga kanye namabheringi okuvuza komoya.Lokhu kusho ukuthi ama-bearings ngokwawo anemishini yokuvala uphawu.
Imvamisa kunenjoloba noma izigxivizo zepulasitiki zobunjiniyela, nezigxivizo zamapuleti ensimbi (noma izivalo zothuli).Izindandatho zokuvala zitholakala ngezindlela ezihlukahlukene zokuvala, ezinemiphumela ehlukene yokuvala.Uma kukhona igebe phakathi kwesigxivizo ne-shaft, lokhu kubizwa ngokuthi i-non-contact seal.Ukukhishwa okuncane, umphumela wokuvala ungcono, kodwa ukwehlisa isivinini se-shaft esivunyelwe;futhi ngokuphambene.Uma kungekho imvume phakathi kwe-seal kanye ne-shaft ejikelezayo, ibizwa ngokuthi uphawu lokuxhumana.Lapho indawo yokuxhumana ye-seal contact lip inkulu, ingcono umphumela wokuvala, kodwa ijubane le-shaft liphansi, futhi ngokuphambene nalokho.
Okwesibili, indlela yokubeka uphawu yokubeka uphawu lothuli
Ukufaka uthuli ngo-Z kusho, ukuvala ngo-S kusho (ukuzwakele indandatho nge-FS yathi; uphawu lwerabha olune-LS luthi).
1.Ikhava yokuvikela uthuli
Ipuleti lensimbi eligcina indandatho elinekhava yothuli, kumabheringi amancane, ipuleti lensimbi eligxiviza elinendandatho yasentwasahlobo engagxili esakhiweni sendandatho yangaphandle.
Ipuleti lensimbi elinesitembu elinekhava yothuli, linciphisa ukuphuma kukawoyela, ipuleti lensimbi lensimbi endaweni yokunyathela indandatho yangaphandle ukuze kuqiniswe isakhiwo.
2.Indandatho yokuvala
Uhlobo lwendandatho egcina i-Teflon ephethe uphawu, esetshenziselwa ikakhulukazi ama-bearings amancane.Indandatho yangaphandle ene-glass fiber I-Teflon indandatho yokuvala indandatho, enendandatho eqinile yasentwasahlobo.
Thintana ne-rubber bearing seal, vimbela ngempumelelo ukungena komzimba wangaphandle.Isigxivizo senjoloba sishunyekwe iringi yangaphandle yeringi kanti uphawu luthintana neringi yangaphakathi.
Ngokuya ngendawo ethize lapho kusetshenziswa khona ama-bearings kanye nezimpawu, izinto ezisetshenziselwa izigqoko zothuli kanye nezimpawu ziyahlukahluka.
