Ntchito ya chonyamulira cha mawilo akumbuyo a galimoto
Ntchito yaikulu ya hub bearing ndi kunyamula kulemera ndikupereka chitsogozo cholondola cha kuzungulira kwa hub. Imanyamula katundu wa axial ndi radial ndipo ndi gawo lofunika kwambiri. Ma bearing achikhalidwe omwe amagwiritsidwa ntchito pamawilo agalimoto amapangidwa ndi magulu awiri a ma roller bearing opindika kapena ma ball bearing. Kukhazikitsa, kuyika mafuta, kutseka ndi kusintha kwa clearance ya ma bearing kumachitika pamzere wopanga magalimoto. Kapangidwe kameneka kamapangitsa kuti zikhale zovuta kusonkhanitsa opanga magalimoto, okwera mtengo komanso osadalirika. Kuphatikiza apo, galimoto ikasamalidwa pamalo okonzedwa, ma bearing amafunikanso kutsukidwa, kupakidwa mafuta ndikusinthidwa. Ma Hub bearing units apangidwa potengera ma bearing a mpira olumikizana ndi ma tapered roller bearing. Amaphatikiza ma seti awiri a ma bearing kukhala amodzi, okhala ndi magwiridwe antchito abwino, osafunikira kusintha clearance, kulemera kopepuka, kapangidwe kakang'ono, mphamvu yayikulu yonyamula katundu, kuyika mafuta kale ngati ma bearing otsekedwa, osafunikira kutseka kwakunja kwa hub, komanso osafunikira kukonza. Agwiritsidwanso ntchito kwambiri m'magalimoto. Palinso chizolowezi chokulitsa pang'onopang'ono ntchito yake m'magalimoto olemera.
Kale, ma hub bearing a magalimoto ankagwiritsidwa ntchito kwambiri m'magawo awiriawiri ngati ma roller kapena ma ball bearing a mzere umodzi. Chifukwa cha chitukuko cha ukadaulo, ma hub unit a magalimoto akhala akugwiritsidwa ntchito kwambiri m'magalimoto. Kukula kwa ntchito ndi kuchuluka kwa ma hub bearing unit akuwonjezeka tsiku ndi tsiku, ndipo tsopano akukula mpaka m'badwo wachitatu: m'badwo woyamba unali ndi ma double-row angular contact bearing. M'badwo wachiwiri uli ndi flange panja pa raceway yokonzera bearing, yomwe imatha kuyikidwa pa axle ndikukhazikika ndi nati. Izi zimapangitsa kuti kusamalira magalimoto kukhale kosavuta. Hub bearing unit ya m'badwo wachitatu imagwiritsa ntchito bearing unit pamodzi ndi anti-lock braking system (ABS). Hub unit idapangidwa ndi flange yamkati ndi flange yakunja. Flange yamkati imalumikizidwa ku drive shaft ndi ma bolts, pomwe outer flange imayika bearing yonse pamodzi. Ma hub bearing kapena ma hub unit osweka kapena owonongeka angayambitse kulephera kosayenera komanso kokwera mtengo kwa galimoto yanu poyendetsa, komanso kuopseza chitetezo chanu.
Chonde samalani ndi zinthu zotsatirazi mukamagwiritsa ntchito ndikuyika ma hub bearing:
Kuti muwonetsetse kuti galimotoyo ndi yotetezeka komanso yodalirika kwambiri, tikukulimbikitsani kuti muziyang'ana ma hub bearing nthawi zambiri mosasamala kanthu za msinkhu wa galimotoyo - samalani ndi zizindikiro zoyambirira za kuwonongeka kwa ma bearing: kuphatikizapo phokoso lililonse la kukangana panthawi yozungulira kapena kuchepa kwa liwiro la mawilo osakanikirana osakanikirana mukatembenuka. Pa magalimoto oyendetsa mawilo akumbuyo, tikukulimbikitsani kuti ma hub bearing akutsogolo azipaka mafuta pamene galimotoyo yayenda makilomita 38,000. Mukasintha makina oletsa mabuleki, yang'anani ma bearing ndikusintha ma seal a mafuta.
Ngati mumva phokoso losazolowereka kuchokera ku malo operekera mpweya, chinthu choyamba komanso chofunikira kwambiri ndikupeza komwe phokosolo limachitika. Pali zinthu zambiri zosuntha zomwe zingayambitse phokoso, kapena zitha kukhala kuti zinthu zina zozungulira zakhudzana ndi zinthu zosazungulira. Ngati zatsimikiziridwa kuti phokosolo ndi lochokera ku pereka mpweya, pereka mpweyawo ukhoza kuwonongeka ndipo uyenera kusinthidwa.
Popeza mikhalidwe yogwirira ntchito yomwe imayambitsa kulephera kwa ma bearing mbali zonse ziwiri chifukwa cha malo ogwirira mawilo akutsogolo ndi yofanana, tikukulimbikitsani kuti muwasinthe awiriawiri ngakhale bearing imodzi yokha yawonongeka.
Ma Hub bearing ndi osavuta kugwiritsa ntchito, ndipo mulimonsemo, njira zoyenera ndi zida zoyenera ziyenera kugwiritsidwa ntchito. Pakusunga, kunyamula ndi kukhazikitsa, zigawo za bearing siziyenera kuwonongeka. Ma bearing ena amafunika kupanikizika kwakukulu kuti akanikizidwe, kotero zida zapadera zimafunika. Onetsetsani kuti mwawerenga buku lothandizira kupanga magalimoto.
Mukayika ma bearing, ayenera kuchitidwa pamalo oyera komanso aukhondo. Tinthu tating'onoting'ono tomwe timalowa m'ma bearing tidzafupikitsanso nthawi yawo yogwira ntchito. Ndikofunikira kwambiri kusunga malo oyera posintha ma bearing. Sikuloledwa kugunda bearing ndi nyundo. Samalani kuti musagwetse bearing pansi (kapena kuigwira molakwika mwanjira yofanana). Musanayike, mkhalidwe wa shaft ndi bearing housing ziyeneranso kuyang'aniridwa. Ngakhale kuwonongeka pang'ono kungayambitse kusakwanira bwino, zomwe zimapangitsa kuti bearing iwonongeke msanga.
Pa ma hub bearing units, musayese kusokoneza ma hub bearing kapena kusintha ma sealing rings a ma hub units; apo ayi, ma sealing rings angawonongeke, zomwe zingalole madzi kapena fumbi kulowa. Ngakhale njira zothamangira za sealing ring ndi mkati mwake zinawonongeka, zomwe zinapangitsa kuti bearing isagwire ntchito kwamuyaya.
Pali mphete yolumikizira maginito mkati mwa mphete yotsekera ya bearing yokhala ndi chipangizo cha ABS. Mphete yolumikizira iyi siyenera kugwedezeka, kukhudzidwa kapena kukhudzana ndi maginito ena. Musanayike, ichotseni m'bokosi lolongedza ndikuisunga kutali ndi maginito, monga ma mota amagetsi kapena zida zamagetsi zomwe zikugwiritsidwa ntchito, ndi zina zotero. Mukayika ma bearing awa, yang'anani singano ya alamu ya ABS pa dashboard kudzera mu mayeso a road condition kuti musinthe momwe ma bearing amagwirira ntchito.
Pa ma hub bearing okhala ndi mphete za ABS magnetic thrust, kuti mudziwe mbali yomwe mphete ya thrust yayikidwapo, mutha kubweretsa chinthu chaching'ono komanso chopepuka pafupi ndi m'mphepete mwa bearing. Mphamvu ya maginito yopangidwa ndi bearing idzachikopa. Mukayika, lozani mbali yokhala ndi mphete ya magnetic thrust mkati, moyang'anizana mwachindunji ndi zigawo zomvera za ABS. Kuyika kolakwika kungayambitse kulephera kwa ntchito ya braking system.
Ma bearing ambiri amakhala otsekedwa ndipo safuna mafuta nthawi yonse ya moyo wawo. Ma bearing ena osatsekedwa, monga ma bearing a roller okhala ndi mizere iwiri, ayenera kudzozedwa ndi mafuta panthawi yoyika. Chifukwa cha kukula kosiyanasiyana kwa mabowo amkati mwa ma bearing, zimakhala zovuta kudziwa kuchuluka kwa mafuta oti muwonjezere. Chofunika kwambiri ndikuwonetsetsa kuti pali mafuta mu ma bearing. Ngati pali mafuta ambiri, ma bearing akazungulira, mafuta ochulukirapo adzatuluka. Chidziwitso chonse: Pakuyika, mafuta onse ayenera kukhala 50% ya malo olowera.
Mukayika mtedza wotsekera, kukula kwa mphamvu ya torque kumasiyana kwambiri chifukwa cha kusiyana kwa mitundu ya mabearing ndi ma bearing housings.
Panthawi yokonza, nthawi zambiri zimapezeka kuti magalimoto ena amakhala ndi phokoso lalikulu loyendetsa. Pambuyo poyang'ana, matayala sawonongeka kwambiri. Mukatembenuza mawilo pa lift, palibe phokoso lodziwika bwino. Izi nthawi zambiri zimachitika chifukwa cha kuwonongeka kosazolowereka kwa hub bearing. Chomwe chimatchedwa abnormal chimatanthauza kuwonongeka kwa bearing komwe kumachitika chifukwa cha kukhazikitsa. Ma bearing akutsogolo a galimoto nthawi zambiri amakhala ma bearing a mizere iwiri. Mukakhazikitsa ma bearing, ngati nyundo ikugwiritsidwa ntchito kuwagunda kapena mphete yamkati ya bearing ikakanikizidwa powayika m'nyumba yosungiramo ma bearing, izi ziwononga msewu wa raceway mbali imodzi ya bearing. Galimoto ikayenda, phokoso limachitika. Komabe, mawilo akachoka pansi, chifukwa cha mbali yabwino ya msewu wa raceway, palibe phokoso lomveka bwino lomwe lingamveke. Kukhazikitsa ndi kugwiritsa ntchito bwino ndiye chinsinsi cha moyo wautali wa ma bearing.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
