Kukhazikitsa ndi Kuchotsa Njira Yogwiritsira Ntchito Common Rolling Bearing

Ma bereji ozunguliraNdi zigawo zazikulu za zida zamakanika, ndipo kukhazikitsa ndi kugawa kwake kumakhudza mwachindunji kulondola kwa magwiridwe antchito, kukhazikika, ndi moyo wautumiki wa zidazo. Njira zoyenera zogwirira ntchito zimatha kupewa mavuto monga kusintha kwa mabeating ndi kuwonongeka kwa msewu wa raceway, motero kuchepetsa chiopsezo cha kulephera kwa zida. Nkhaniyi ipereka chiyambi chatsatanetsatane cha njira zoyika ndi kugawa zomwe zimagwiritsidwa ntchito kwambiri.mabearing ozungulira, pamodzi ndi malangizo enieni ogwirira ntchito.

1. Njira Yokhazikitsira ndi Kugwiritsa Ntchito Zopangira Zozungulira

Njira zitatu zokonzekera zikufunika musanayike: Choyamba, onetsetsani kutichogwiriraChitsanzocho chikukwaniritsa zofunikira pa kapangidwe kake mwa kuyang'ana zolakwika pamwamba monga dzimbiri kapena mikwingwirima, ndikuzungulira mphete yamkati kapena yakunja kuti zitsimikizire kuti ikugwira ntchito bwino popanda kumamatira. Chachiwiri, yeretsani shaft journal, bearing housing bore, ndi zida zoyikira kuti muchotse mafuta, zodulidwa zachitsulo, ndi zina zodetsa. Chachitatu, konzani zida kuphatikizapo nyundo, ndodo zamkuwa, manja, zida zotenthetsera (monga, uvuni wamafuta), ndi ma micrometer malinga ndi kukula kwa bearing ndi zofunikira pakuyikira.

1. Njira yokhazikitsa yozizira: yoyenera ma bereki ang'onoang'ono okhala ndi mainchesi amkati ≤50mm

Njirayi siifuna kutentha ndipo imafuna kugwiritsa ntchito mphamvu mwachindunji pogwiritsa ntchito zida. Njira: 1. Mangani bearing bwino pa shaft journal, kuonetsetsa kuti kumapeto kwake kukuyenda bwino ndi phewa. 2. Ikani sleeve yokhala ndi m'mimba mwake wamkati wokulirapo pang'ono kuposa shaft ndi m'mimba mwake wakunja wocheperako pang'ono kuposa mphete yakunja ya bearing, kupewa kukhudza mwachindunji mphete yakunja. 3. Ikani nyundo yofanana kumapeto kwa sleeve pamene mukuyang'anira malo a bearing mpaka bearing ikugwirizana bwino ndi phewa la shaft. 4. Zungulirani bearing ndi dzanja mutatha kuyiyika kuti mutsimikizire kuti ikugwira ntchito bwino popanda kukana.

2. Njira yoyika yotentha: yoyenera ma bere apakati ndi akulu okhala ndi mainchesi amkati> 50mm

Gwiritsani ntchito mfundo zokulitsa kutentha ndi kupindika kuti muwonjezere mphete yamkati yachogwirira, potero kuchepetsa kukana kwa kuyika. Njira: Ikani bearing mu mafuta oyera a transformer kapena mafuta apadera otenthetsera bearing, kuonetsetsa kuti yamira mokwanira ndi malo osachepera 50mm kuchokera pansi pa chidebe kuti kutentha kusamagwirizane bwino. Pitirizani kutentha pa 80-100°C (pamwamba pa 120°C), ndi kuyang'anira nthawi yeniyeni pogwiritsa ntchito thermometer. Nthawi yotenthetsera ya mphindi 20-40 imatsimikizira kufalikira kwa kutentha kofanana m'mphete zamkati ndi zakunja. Mukachotsa, pukutani nthawi yomweyo zodetsa pamwamba ndi nsalu yoyera ya thonje. Gwirizanitsani bearing ndi khosi la shaft ndikuyiyika mwachangu, pogwiritsa ntchito ndodo yamkuwa kuti mugwire nkhope yamkati ya mphete kuti muyike mpaka ifike polumikizana bwino ndi phewa. Bearing idzachepa mwachibadwa ikazizira kuti ipange chisindikizo cholimba ndi khosi la shaft. Mukamaliza kuziziritsa, onaninso kusinthasintha kozungulira.

3. Kukhazikitsa nyumba yopangira zifaniziro: poganizira momwe mphete yakunja imagwirira ntchito komanso momwe nyumba yopangira zifaniziro imagwirira ntchito

Kuti zigwirizane pakati pa mphete yakunja ya bearing ndi holo, ikani mafuta ku mphete yakunja ndikuyiyika pogogoda bwino kumapeto ndi chikwama. Kuti zigwirizane bwino, ingoikani bearing mu holo, ndikuwonetsetsa kuti mphete yakunja ikugwirizana ndi sitepe yopezera malo. Mukayika, yesani radial runout ndi axial movement pogwiritsa ntchito micrometer, ndi zolakwika zomwe zikukwaniritsa zofunikira zolondola za chipangizocho.

2. Njira Yochotsera ndi Kugwiritsa NtchitoKunyamula Zozungulira

Musanachotse bedi, yeretsani bearing ndi malo ozungulira, ndipo yang'anani malo oyika bearing ndi komwe ikuyang'ana kuti mupewe zolakwika panthawi yokonzanso. Sankhani zida zoyenera zochotsera kutengera njira yoyika bearing, monga zokokera, zida zochotsera, zida zotenthetsera, kapena makina a hydraulic.

1. Njira yochotsera Rama: njira yochotsera yomwe imagwiritsidwa ntchito kwambiri, yoyenera ma bearing okhala ndi malekezero owonekera a shaft

Sankhani chokokera chomwe chili ndi zofunikira zogwirizana kuti muwonetsetse kuti zikhadabo zake zikugwira bwino mphete yamkati ya bearing, kuletsa kusintha kwa kugundana ndi mphete yakunja. Lumikizani nsonga ya ndodo ya screw ndi pakati pa shaft, kenako zungulirani ndodoyo pang'onopang'ono kuti mugawire mphamvu yofanana pa zikhadabozo kuti bearing ichotsedwe bwino. Pa ma bearing olimba, ikani mafuta pang'ono pa mphete yamkati kapena gwiritsani ntchito mfuti yotenthetsera kuti mutenthetse mwachangu (kutentha ≤100°C). Kutambasuka kwa kutentha ndi kufupika kumeneku kumachepetsa kulimba musanachotse.

2. Njira yogogoda ndi kusokoneza: yoyenera kutsogolera pang'ono komanso kopanda kanthu

Gwiritsani ntchito ndodo yamkuwa kapena chinthu chofewa kuti mukanikize kumapeto kwa mphete yamkati ya bearing ndikugogoda mofanana kuzungulira kwake. Ikani mphamvu pang'ono kuti mupewe kuwonongeka kwa shaft journal kapena bearing. Ngati bearing ili kumapeto kwa shaft, sungani shaft ndikugogoda mwachindunji kumapeto ndi nyundo, pogwiritsa ntchito mphamvu yotsutsana kuti muchotse bearing. Pa ma bearing omwe ali pakati pa shaft, choyamba gwirizanitsani malo ogwiritsira ntchito mphamvu ndi sleeve musanagogode.

2. Njira yochotsera ma hydraulic: yoyenera kusokoneza kwakukulu ndi kwakukulu

Pamene dzenje la mafuta a hydraulic lakonzedwa kumapeto kwa shaft, lumikizani chipangizo cha hydraulic ku dzenje la mafuta ndikulowetsa pang'onopang'ono mafuta amphamvu kuti pakhale mpata pakati pa shaft ndi mphete yamkati ya bearing. Nthawi yomweyo, gwiritsani ntchito chokokera kuti chithandize kuchotsa bearing bwino. Njirayi imachepetsa kuwonongeka kwa shaft ndi bearing, kuonetsetsa kuti zigawozo zikugwiritsidwanso ntchito.

III. Malangizo Opewera

Mukakhazikitsa ndi kumasula, musagunde mwachindunji zinthu zozungulira za bearing kapena makhola ndi nyundo kuti mupewe kuwonongeka kwakukulu. Gwiritsani ntchito mafuta apadera potenthetsera mabearing kuti mupewe kuipitsidwa. Mukamasula, yeretsani bwino ndikuyang'ana mabearing. Sinthani bearing iliyonse ndi kuwonongeka, ming'alu, kapena zolakwika zina nthawi yomweyo. Kutsatira kwambiri njira zokhazikika ndikofunikira kuti muwonetsetse kuti mabearing ndi zida zikugwira ntchito bwino, ndipo zofunikira zonse za ndondomekoyi ziyenera kutsatiridwa mosamala.

Kukhazikitsa ndi kusokoneza bwino ma rolling bearings ndikofunikira kwambiri kuti zitsimikizire kuti zida zikuyenda bwino, kuchepetsa ndalama zokonzera, komanso kukulitsa nthawi yogwira ntchito. Mwa kugwiritsa ntchito njira zoyenera, kusankha zida zoyenera, komanso kusunga malamulo okhwima okhudza ntchito, mabizinesi amatha kuchepetsa kwambiri chiopsezo cha kulephera kwa makina ndi kuwonongeka kwa magwiridwe antchito.

Monga wogulitsa wodalirika wa zinthu zolondola kwambirichogwiriramayankho,TPimapereka zinthu zosiyanasiyana komanso chithandizo chaukadaulo chopangidwa kuti chigwirizane ndi mitundu yosiyanasiyana ya zinthuntchito zamafakitale. Mothandizidwa ndi luso lapamwamba lopanga zinthu, kasamalidwe kabwino kwambiri, komanso njira yoganizira makasitomala, TP yadzipereka kuthandiza ogwirizana nawo padziko lonse lapansi kuti akwaniritse bwino ntchito yawo, kuchepetsa kulephera, komanso kukhazikika kwa ntchito kwa nthawi yayitali. Kuti mudziwe zambiri kapena upangiri waukadaulo, chonde.kulumikizana TP.
