Kuyambira kapangidwe kake, zipangizo mpaka malo ogwiritsira ntchito, zikuthandizani kumvetsetsa chifukwa chake oponya amatha "kunyamula kulemera" komanso momwe mungasankhire.
Anthu ambiri akuda nkhawa ndi kulemera kotani komwe kavalo uyu angapirire posankha mawilo?
Pamwamba, mphamvu yonyamula katundu ingawoneke ngati chinthu chosavuta, koma kwenikweni, sikokwanira kupanga ziganizo kutengera nambala imodzi yokha. Mphamvu yonyamula katundu ya ma casters imakhudzana ndi kapangidwe kake, mtundu wa zinthu, kukula kwa mawilo, kapangidwe ka mabearing, ndi malo enieni ogwiritsira ntchito. Mawilo a diameter yofanana akhoza kukhala ndi mphamvu yotsika kwambiri yonyamula katundu ngati kapangidwe kothandizira, zinthu za pamwamba pa mawilo, kapena mtundu wa mabearing ndi osiyana.
Chifukwa chake, kuti mudziwe malire a oponya katundu, munthu sayenera kungodalira deta yotsatsa, komanso kuisanthula mogwirizana ndi mikhalidwe yeniyeni yogwirira ntchito.
1. Kapangidwe ka kapangidwe kake kamatsimikizira maziko onyamula katundu
Kutha kwa ma caster kunyamula katundu kumadalira kapangidwe kake konse. Ma caster opepuka amagwiritsidwa ntchito kwambiri pazida monga mipando yaofesi, makabati osungira mafayilo, ndi ngolo zazing'ono. Ali ndi kapangidwe kosavuta ndipo amasinthasintha komanso kupepuka, ndipo nthawi zambiri amanyamula katundu kuyambira pa ma kilogalamu makumi angapo mpaka pafupifupi 100.
Ngati njira yogwiritsira ntchito isinthidwa kukhala mafakitale, malo osungiramo katundu, zida zoyendetsera zinthu, kapena makina olemera, ma casters amafunika mabulaketi olimba, matupi okhuthala, ndi maulumikizidwe apamwamba. Ma casters olemera kapena onenepa kwambiri amatha kunyamula kulemera kamodzi kwa makilogalamu mazana angapo, ndipo mitundu yapadera imatha kufika matani angapo.
Izi zikutanthauza kuti, kulemera komwe chida chopopera chingapirire sikudalira kukula kwake, koma ngati chapangidwira zinthu zolemera. Mphamvu ya kapangidwe kake siyokwanira, ndipo ngakhale zipangizo zabwino kwambiri sizingathe kupirira katundu wolemera kwa nthawi yayitali.
2. Zipangizo zosiyanasiyana zimapangitsa kuti ntchito yonyamula katundu ikhale yosiyana
Zipangizozo zimatsimikiza mphamvu, kukana kuwonongeka, kukana kugwedezeka, ndi nthawi yogwira ntchito ya ma casters. Ma core a mawilo achitsulo wamba, chitsulo chosungunuka, ndi mabulaketi achitsulo ndi oyenera malo okhala ndi katundu wambiri komanso wamphamvu, ndipo mphamvu zawo zonyamula katundu nthawi zambiri zimakhala zolimba.
Nayiloni, polyurethane, mapulasitiki osinthidwa ndi zinthu zina zimapezekanso m'malo ogwirira ntchito apakatikati komanso olemera. Ubwino wawo ndi kulemera kopepuka, kugwiritsa ntchito mopanda phokoso, kosavuta kugwiritsa ntchito pansi, komanso kukana kuwonongeka ndi dzimbiri.
Kapangidwe kena kofala ndi pakati pa gudumu lachitsulo lokulungidwa ndi rabara kapena polyurethane. Mtundu uwu wa caster sumangokhala ndi mphamvu yonyamula katundu ya pakati pa gudumu, komanso umaganiziranso kuyamwa kwa shock, kuchepetsa phokoso, ndi chitetezo cha nthaka, kotero umagwiritsidwa ntchito kwambiri m'mafakitale, zipatala, masitolo akuluakulu, ndi zida zoyendetsera zinthu.
Choncho, sitingangoganiza kuti zitsulo zopopera zitsulo nthawi zonse zimakhala zabwino ndipo zitsulo zopopera zapulasitiki sizolimba. Chinsinsi chimadalirabe mtundu wa zinthu, fomula, komanso ngati zili zoyenera kugwiritsidwa ntchito.
3. Kukula kwa gudumu kukakhala koyenera, mphamvu yonyamula katundu imakhala yokhazikika
M'lifupi ndi m'lifupi mwa mawilo zimakhudza mwachindunji mphamvu zawo zonyamula katundu. Kawirikawiri, m'lifupi mwa mawilo, kumakhala kosavuta kudutsa m'mipata ya pansi, m'mathireyi a chingwe, ndi m'zopinga zazing'ono, ndipo zimathanso kuchepetsa kukana panthawi yogubuduza. Pazida zolemera, m'lifupi mwa mawilo nthawi zambiri zimakhala zopulumutsa ntchito komanso zokhazikika.
Kuchuluka kwa mawilo n'kofunika kwambiri. Gudumu likakula, malo okhuzana ndi nthaka amakula, ndipo kulemera kwake kumagawika mofanana, zomwe zimachepetsa kupanikizika pa dera lililonse. Izi sizothandiza kokha ponyamula katundu, komanso zimachepetsa chiopsezo cha mawilo kukodwa pansi kapena kuphwanya pansi.
Chifukwa chake, ma caster omwe amagwiritsidwa ntchito kwambiri ponyamula katundu wolemera nthawi zambiri samangokulitsa zinthuzo, komanso nthawi yomweyo amakulitsa kukula kwa mawilo ndi m'lifupi, kuti magwiridwe antchito onse onyamula katundu akhale odalirika kwambiri.
4. Kapangidwe ka bereji kangakhudze luso lonyamula katundu ndi kuyendetsa galimoto
Anthu ambiri amangoyang'ana kwambiri mawilo okha, koma amanyalanyaza mabearing. Ndipotu, mabearing ndi zinthu zofunika kwambiri zomwe zimatsimikizira ngati ma casters amatha kuzungulira bwino, kusuntha ndikugwiritsidwa ntchito kwa nthawi yayitali.
Maberiya a manja ali ndi kapangidwe kosavuta, mtengo wotsika, ndipo ndi oyenera kugwiritsidwa ntchito mopepuka kapena pafupipafupi. Koma pansi pa katundu wolemera, kukana kukangana kudzawonjezeka kwambiri, zomwe zimapangitsa kuti zikhale zovuta kukankhira, ndipo kugwiritsidwa ntchito kwa nthawi yayitali kumakhala kosavuta kusweka.
Ma bearing a mpira ndi ma roller bearing ndi oyenera kwambiri pazochitika zapakati mpaka zolemera. Angasinthe sliding friction kukhala roll friction, kusunga magwiridwe antchito abwino ozungulira pomwe bearing weight, osati kungopangitsa kuti kukankha kukhale kosavuta, komanso kukulitsa moyo wonse wa ma casters.
Pazida zomwe zimafuna kuyenda kwa nthawi yayitali, kusankha ma bearing apamwamba nthawi zambiri ndikofunikira kwambiri kuposa kungowonjezera kuuma kwa mawilo.
5. Malo ogwiritsira ntchito ndiye chinsinsi choyesera mphamvu yonyamula katundu
Deta yokhudzana ndi kunyamula katundu ya akatswiri oponya miyala nthawi zambiri imapezeka m'malo abwino kwambiri. Komabe, pogwiritsira ntchito kwenikweni, momwe nthaka ilili, liwiro la kuyenda, kuchuluka kwa momwe imagwiritsidwira ntchito, komanso kutentha kwa malo onse zimatha kukhudza momwe makina oponya miyala amagwirira ntchito.
Mwachitsanzo, pansi pa epoxy kapena simenti, ma casters nthawi zambiri angagwiritsidwe ntchito pafupi ndi malo onyamula katundu; Koma ngati pali mabowo, mipata, miyala, malo otsetsereka pansi, kapena ngati zida ziyenera kuzunguliridwa pafupipafupi ndikuyenda mwachangu, ma casters adzakhala ndi mphamvu zambiri komanso mbali.
Kuphatikiza apo, malo monga kutentha kwambiri, kutentha kochepa, chinyezi, ndi zinthu zowononga zimathanso kukhudza momwe zinthu ndi mabearing amagwirira ntchito pamwamba pa mawilo zimagwirira ntchito. Ma casters ena amakhala ndi magwiridwe antchito abwino onyamula katundu kutentha kwa chipinda, koma mawonekedwe awo amatha kusintha m'malo otentha kwambiri kapena otsika, zomwe zimapangitsa kuti mphamvu yonyamula katundu ichepe komanso moyo wawo ukhale wautali.
Choncho, posankha ma caster, simuyenera kungoganizira za mphamvu zawo zonyamula katundu zosasinthasintha, komanso ngati zili zoyenera kugwiritsidwa ntchito.
6. Momwe mungasankhire njira yabwino kwambiri yonyamulira katundu kwa oponya
Posankha, ndi bwino kuwerengera kaye kulemera konse kwa chipangizocho, komwe ndi kulemera kwa chipangizocho kuphatikiza kulemera kwa katundu wolemera. Kenako gawani katunduyo kutengera kuchuluka kwa makina oponyera, koma sangagawanidwe ndi kulemera konse ndi kuchuluka kwa makina oponyera. Chifukwa chipangizocho chikayenda, chikuzungulira, kapena chili pansi pa nthaka yosagwirizana, si makina onse oponyera omwe amagwidwa ndi mphamvu yofanana.
Mu ntchito zenizeni, zida zamagudumu anayi nthawi zambiri zimafuna kuti malire achitetezo asungidwe kutengera kulemera kwa magudumu atatu. Izi zitha kuchepetsa chiopsezo cha kusinthika, kugwedezeka, kapena kuwonongeka ngakhale nthaka ili yosagwirizana kapena ikukhudzidwa ndi mphamvu zosagwirizana.
Ngati zipangizozo zili ndi katundu wolemera, ma frequency ambiri, komanso momwe zimakhudzira anthu, chitetezo chiyenera kukonzedwanso kuti mawilo asakule kwambiri kwa nthawi yayitali.
Mapeto
Malire a ma casters onyamula katundu si chinthu chokhachokha, koma zotsatira za zotsatira za kapangidwe kake, zinthu, kukula, ma bearing, ndi malo ogwiritsidwa ntchito. Kusankha mawilo oyenera sikuti kungokhudza kutha kuyenda kokha, komanso kusunga zidazo kukhala zotetezeka, zokhazikika, komanso zosavuta kugwiritsa ntchito nthawi yayitali.
Ngati mukufuna kusankha mawilo oyenera, njira yotetezeka sikuti kungoyang'ana manambala onyamula katundu omwe ali pa kabukhu ka zinthu, koma kupanga chigamulo chokwanira kutengera kulemera kwa zida, momwe nthaka ilili, kuchuluka kwa kayendedwe ka zinthu, komanso zofunikira pa chilengedwe. Ma casters osankhidwa mwanjira imeneyi ndi oyenera kugwiritsidwa ntchito kwa nthawi yayitali.
