Kapangidwe ka kugwedezeka kwa ma bereti Nthawi zambiri, mayendedwe odzigudubuza okha sapanga phokoso."Phokoso lokhala ndi phokoso" lomwe nthawi zambiri limamveka limakhala phokoso la kugwedeza mwachindunji kapena mosadziwika bwino ndi mawonekedwe ozungulira.Ichi ndichifukwa chake nthawi zambiri vuto laphokoso limatha kuwonedwa ngati vuto la vibration lomwe limakhudza ntchito yonse yonyamula.
(1) Kugwedezeka kwachisangalalo komwe kumachitika chifukwa cha kusintha kwa kuchuluka kwa zinthu zogubuduza: Pamene katundu wa radial amagwiritsidwa ntchito pamtundu wina, kuchuluka kwa zinthu zonyamula katundu kudzasintha pang'ono panthawi yogwira ntchito, zomwe zimayambitsa kupatuka kwa kayendetsedwe ka katundu.Kugwedezeka komwe kumachitikako sikungalephereke, koma kumatha kuchepetsedwa ndi axial preloading, yomwe imayikidwa pazinthu zonse zogubuduza (zosagwirizana ndi mayendedwe a cylindrical roller).
(2) Kuwonongeka pang'ono: chifukwa cha zolakwika za opareshoni kapena kukhazikitsa, gawo laling'ono lanjira zonyamula ndi zinthu zogubuduza zitha kuwonongeka.Pogwira ntchito, kugubuduza zida zowonongeka kumatulutsa ma frequency a vibration.Kusanthula pafupipafupi kwa vibration kumatha kuzindikira zida zowonongeka zowonongeka.Mfundoyi yakhala ikugwiritsidwa ntchito pazida zowunikira kuti ziwone kuwonongeka.Kuti muwerenge kuchuluka kwa ma frequency, chonde onani pulogalamu yowerengera "Bearing Frequency".
(3) Kulondola kwa zigawo zogwirizana: Pankhani yogwirizana kwambiri pakati pa mphete yonyamula ndi mpando wonyamula kapena shaft yoyendetsa galimoto, mphete yonyamulira ikhoza kusokonezeka pofananiza mawonekedwe a mbali yoyandikana nayo.Ngati yapunduka, imatha kunjenjemera panthawi yogwira ntchito.
(4) Zoipitsa: Ngati zikuyenda m’malo oipitsidwa, zonyansa zingaloŵe m’mbali ndi kuphwanyidwa ndi zinthu zogubuduzika.Mlingo wa kugwedera opangidwa zimadalira chiwerengero, kukula ndi zikuchokera wosweka wodetsedwa particles.Ngakhale kuti sichimapanga mawonekedwe afupipafupi, phokoso losokoneza limatha kumveka.
Zomwe zimayambitsa phokoso lopangidwa ndi kugudubuza mayendedwe ndizovuta kwambiri.Chimodzi ndi kuvala kwa malo okwerera mkati ndi kunja kwa mphete.Chifukwa cha kuvala kotereku, mgwirizano wofananira pakati pa kunyamula ndi nyumba, ndi kunyamula ndi tsinde kumawonongeka, zomwe zimapangitsa kuti olamulira achoke pa malo oyenerera, ndipo phokoso losazolowereka limachitika pamene shaft ikuyenda mofulumira kwambiri.Pamene kubereka kumatopa, chitsulo pamwamba pake chidzatuluka, chomwe chidzawonjezeranso kutulutsa kwamtundu wa kubereka ndi kutulutsa phokoso losazolowereka.Kuphatikiza apo, kusakwanira kwamafuta onyamula, kupanga kukangana kowuma, ndi kusweka kwapang'onopang'ono kumayambitsa phokoso lachilendo.Pambuyo pa kubereka ndi kumasulidwa, khola limamasulidwa ndikuwonongeka, ndipo phokoso lachilendo lidzapangidwanso.
Ma bearings ayenera kugwiritsidwa ntchito mosamala m'moyo watsiku ndi tsiku.Tiyeni tione zinthu zisanu ndi zinayi zimene tiyenera kuziganizira.
1. Zigawo zong'ambika mu chotuta zili ngati cholumikizira mipeni.Ma rivets nthawi zambiri amapangidwa ndi kuzizira kozizira ndipo sayenera kutenthedwa panthawi yothamanga.Kutentha kudzachepetsa mphamvu ya zinthu.Pambuyo pa riveting, kupanga nkhonya kumagwiritsidwa ntchito kulimbitsa kulimba kwa tsamba ndi tsinde la mpeni.
2. Zigawo zowonongeka, makamaka pin shafts, kukanikiza zidutswa, manja, ndi nyanga sizingasinthidwe ndi kukonzedwa ndi batala wochuluka panthawi yokonza, monga kugwiritsa ntchito nthawi yaitali ziwalo zomwe zimavala mpaka malire zidzachititsa kuti moyo wa makina ena ukhalepo. kufupikitsidwa .
3. Kukonza ma shafts opanda makina olinganiza.Pokonza ma shafts osiyanasiyana omwe amafunikira kukhazikika, cholumikizira chimatha kuyikidwa kumapeto kwa shaft, kumangirira pansagwada zitatu za lathe, ndipo mbali inayo imatha kuthandizidwa ndi pakati.Ngati lathe ndi lalifupi, pakati angagwiritsidwe ntchito.Chimango chimangirira chonyamula cha SKF choyikidwa pa shaft kumapeto kwina mpaka kusanja kukonzedwa.Koma polinganiza kulemera kwake, gwiritsani ntchito zomangira kuti mukhwime, ndipo yesetsani kuti musagwiritse ntchito kuwotcherera kwamagetsi kuti muchepetse kulemera kwake.
4. Pokonzekera, chifukwa cha mitundu yosiyanasiyana ya zipangizo zonyamulira, sizili zophweka kugula, ndipo zimatha kukonzedwa ndi zinyalala shafts.Pakalipano, zitsulo zambiri m'dziko lathu zimapangidwa ndi 45 # carbon steel.Ngati kuzimitsidwa ndi kutentha kuli kofunikira, kungagwiritsidwe ntchito pazikhalidwe zoipa.Oxygen ndi ng'anjo yapadziko lapansi zimatenthetsa mbali zofunika kuti zikhale zofiira ndi zakuda ndikuziyika m'madzi amchere, malingana ndi kufunikira.
5. Pamene mukukonza zida za manja, kokerani poyambira mafuta mu dzenje la manja momwe mungathere.Chifukwa ndizovuta kwambiri kuthira mafuta mbali zina za chotungira, batala ndi mafuta olemera a injini amatha kugwiritsidwa ntchito komwe kumakhala kovuta kuthira mafuta, kupatula manja a nayiloni.Kumene manja a nayiloni amagwiritsidwa ntchito, ndibwino kuti musawasinthe ndi chitsulo chosungunula, mkuwa kapena aluminiyamu, chifukwa manja a nayiloni amalimbana ndi vuto linalake ndipo sangawonongeke.
6. Kukonzekera kwa fungulo ndi keyway pa pulley lamba ndi shaft ziyenera kuonetsetsa kuti kukula kwake sikumasintha pasadakhale.Osawonjezera kukula kwa kiyi, apo ayi zidzakhudza mphamvu ya shaft.Msewu wopita ku shaft ukhoza kukonzedwa ndi chowotcherera chamagetsi ndikugaya mbali ina ya kiyi yakale.Njira yayikulu, njira yayikulu pa pulley imatha kukhazikitsidwa ndi njira yamanja (kusintha koyenera).Mukamaliza kukonza, gwiritsani ntchito screw ya countersunk kuti mugwire m'manja kuti mumangitse kiyi.
7. Konzani gawo la hydraulic la chokolola.Chotsani wogawa ndi valavu yochepetsera, ndipo gwiritsani ntchito pampu ya mpweya kukakamiza mapaipi.Mafuta a hydraulic ayenera kusefedwa ndi kutha pamene mafuta a hydraulic amatsitsimutsidwa.Kukonzekera kwa msonkhano wa hydraulic makamaka chisindikizo.Ndi bwino kusintha chisindikizocho mutachichotsa.
