Chizvarwa chekuzunguzika mumabhengi Kazhinji, mabheji anokunguruka pachawo haaburitse ruzha.Iyo "inotakura ruzha" iyo inowanzo nzwikwa inonyatso kurira kweiyo kurira kwakananga kana zvisina kunanga kuzunguza neyakatenderedza chimiro.Ichi ndicho chikonzero nguva zhinji dambudziko reruzha richigona kutorwa sedambudziko revibration rinosanganisira iyo yese kutakura application.
(1) Kudengenyeka kwemufaro kunokonzerwa nekuchinja kwehuwandu hwezvinhu zvakatakurwa zvinotenderedzwa: Kana radial mutoro ukaiswa kune imwe fani, huwandu hwezvinhu zvinotenderedza zvinotakura zvinoshanduka zvishoma panguva yekushanda, izvo zvinokonzeresa kutsauka kwenzira yekuremedza.Kudengenyeka kunoguma hakudzivisiki, asi kunogona kuderedzwa neaxial preloading, iyo inotakurwa pane zvese zvinotenderedza zvinhu (zvisingashande kune cylindrical roller bearings).
(2) Kukuvadzwa kwechikamu: nekuda kwekushanda kana kukanganisa kwekuisa, chikamu chidiki chekutakura mijaho uye zvinhu zvinotenderedza zvinogona kukuvara.Mukushanda, kukunguruka pamusoro pezvakakuvadzwa kutakura zvinhu kunoburitsa chaiyo vibration frequency.Vibration frequency ongororo inogona kuona yakakuvadzwa inotakura zvikamu.Iyi nheyo yakashandiswa kune mamiriro ekutarisisa michina kuti ione kukuvara kwekutakura.Kuti uverenge kutakura frequency, ndapota tarisa kune yekuverenga chirongwa "Bearing Frequency".
(3) Kururama kwezvikamu zvakabatana: Muchiitiko chekuvhara kwepedyo pakati pemhete yekutakura uye chigaro chekutakura kana dhiraivha shaft, mhete yekutakura inogona kukanganiswa nekufananidza chimiro chechikamu chiri pedyo.Kana ikaremara, inogona kudengenyeka panguva yekushanda.
(4) Zvinosvibisa: Kana zvichimhanya munzvimbo ine tsvina, tsvina inogona kupinda muberengi yopwanywa nezvinhu zvinokunguruka.Iyo dhigirii yekuzunguza inogadzirwa zvinoenderana nenhamba, saizi uye kuumbwa kweakapwanyika tsvina yetsvina.Kunyange zvazvo isingabudisi chimiro chefrequency, ruzha runokanganisa runogona kunzwika.
Zvikonzero zveruzha rwunogadzirwa nekukunguruka mabhengi zvakanyanya kuoma.Imwe ndeyekupfekedzwa kwekusangana kwezvindori zvemukati nekunze zvekutakura.Nekuda kwerudzi urwu rwekupfeka, hukama hwehukama pakati pekutakura neimba, uye kubereka uye shaft zvinoparadzwa, zvichiita kuti axis ibve panzvimbo chaiyo, uye ruzha rusina kujairika runoitika kana shaft iri kufamba nekumhanya kukuru.Kana kutakura kwakaneta, simbi iri pamusoro payo inoputika, iyo inowedzerawo kujekesa kwemavara ekubereka uye kuburitsa ruzha rusina kujairika.Pamusoro pezvo, kusakwana kwekutakura lubrication, kuumbwa kweganda rakaoma, uye kutakura kuputsika kunokonzeresa ruzha rusina kujairika.Mushure mokunge kutakura kwapera uye kusunungurwa, keji inosunungurwa uye yakakuvadzwa, uye ruzha rusina kujairika ruchabudiswawo.
Bearings dzinoda kunyatsoshandiswa muhupenyu hwezuva nezuva.Ngatitarisei zvinhu zvipfumbamwe zvatinofanira kupa ngwariro kwazviri.
1. Mativi anotsemuka ari mucheki akafanana nebanga rinofambiswa.Iwo ma rivets anowanzo gadzirwa nekutonhora extrusion uye haafanire kupiswa panguva yeriveting.Kupisa kunoderedza kusimba kwezvinhu.Mushure mokunge riveting, punch yekugadzira inoshandiswa kusimbisa kusimba kweblade uye shaft yebanga.
2. Zvikamu zvinotapukira, kunyanya mapini mapini, zvidimbu zvekutsikirira, maoko, uye nyanga hazvigone kutsiviwa uye kugadziridzwa neruta rakawanda panguva yekugadzirisa, sekushandisa kwenguva refu kwezvikamu zvakapfekwa kusvika pakugumira kuchaita kuti hupenyu hwemimwe michina huvepo. shortened .
3. Kugadziriswa kweshafts pasina kuenzanisa muchina.Paunenge uchigadzirisa mashaft akasiyana-siyana anoda kuenzana, simbi inopinza inogona kuiswa kune imwe mugumo we shaft, yakasungirirwa pashaya nhatu dze lathe, uye imwe mugumo inogona kutsigirwa nechepakati.Kana lathe iri pfupi, nzvimbo yacho inogona kushandiswa.Iyo furemu inosunga iyo SKF inotakura yakaiswa pane shaft kune imwe magumo kusvika chiyero chagadziriswa.Asi kana uchienzanisa huremu, shandisa screws kuomesa, uye edza kusashandisa welding yemagetsi kuenzanisa huremu.
4. Mukugadzirisa, nekuda kwemhando dzakasiyana-siyana dzekutakura zvinhu, hazvisi nyore kutenga, uye zvinogona kushandiswa nemarara shafts.Parizvino, mazhinji ematanda munyika yedu anonyanya kugadzirwa ne45 # kabhoni simbi.Kana kudzima uye kupisa kunodiwa, inogona kushandiswa mumamiriro ezvinhu akaipa.Okisijeni nechoto chepasi zvinopisa zvikamu zvinodiwa kune zvitsvuku uye zvitema uye zviise mumvura ine munyu, zvichienderana nezvinodiwa.
5. Paunenge uchigadzirisa zvikamu zve sleeve, dhonza groove yemafuta mugomba re sleeve zvakanyanya sezvinobvira.Nekuda kwekuti zvakanyanya kunetsa kuwedzera mamwe mativi emukohwi, bota nemafuta einjini inorema zvinogona kushandiswa pazvinenge zvakaoma kuwedzera mafuta, kunze kwemaoko enaironi.Iko kunoshandiswa maoko enylon, zviri nani kuti usatsive nesimbi yakakandwa, mhangura kana aluminium, nekuti mapfumo enylon anomira nekukanganisa uye haazoregi.
6. Kugadziriswa kwekiyi uye keyway pane bhanhire pulley uye shaft inofanira kuve nechokwadi kuti ukuru hahuna kuchinja mberi.Usambofa wakawedzera saizi yekiyi, zvikasadaro zvinokanganisa simba re shaft.Iyo kiyi pa shaft inogona kugadziriswa nemagetsi welding filler uye yakanyungudutswa yakatarisana nekiyi yekare.A keyway, kiyi pa pulley inogona kuiswa ne sleeve (transition fit) nzira.Mushure mekugadzirisa kwapera, shandisa siruunk ye countersunk kuti ubate mu sleeve kuti usimbise kiyi.
7. Gadzirisa hydraulic chikamu chemukohwi.Bvisa muparadzi uye vharafu yekudzikisa, uye shandisa pombi yemhepo kumanikidza mapaipi.Iyo hydraulic mafuta inofanirwa kusefa uye kupera simba kana iyo hydraulic oiri ichiiswazve.Kugadziriswa kweiyo hydraulic assembly inonyanya kuve chisimbiso.Zvakanakisisa kutsiva chisimbiso mushure mokuchibvisa.
