Mavuto amtundu wamagalimoto obwera chifukwa cha mayendedwe osayenera

Magalimoto amagalimoto nthawi zonse amakhala mutu womwe umakambidwa kwambiri pazinthu zamagalimoto. Zogulitsa zamagalimoto zosiyanasiyana zimafunikira mayendedwe ofanana kuti zigwirizane nazo. Ngati mayendedwe sanasankhidwe bwino, pangakhale mavuto monga phokoso ndi kugwedezeka komwe kumakhudza mwachindunji ntchito ya galimoto. zimakhudza moyo wautumiki.

Mipira yozama kwambiri ndi imodzi mwa mitundu yomwe imagwiritsidwa ntchito kwambiri. Ma motors m'malo ogwiritsira ntchito apadera ali ndi zofunikira zosiyanasiyana za mayendedwe. Ngati ndi kotheka, zofunikira zenizeni ziyenera kuyikidwa patsogolo pakunyamula zida ndi njira zopangira.

Phokoso la mayendedwe a mpira wakuya groove amatha kufalikira kudzera mumayendedwe amapangidwe kapena sing'anga ya mpweya. Mpira wakuya wozungulira wozungulira wokhawokha ndiye gwero la mawu kapena kugwedezeka, kumayambitsa kugwedezeka kapena phokoso, makamaka kuchokera ku kugwedezeka kwachilengedwe kwa chimbalangondo ndi kugwedezeka komwe kumabwera chifukwa chakuyenda kwachibale mkati mwa chimbalangondo.

Pakugwiritsa ntchito kwenikweni, kusankha kwamafuta onyamula, kuchuluka kwa kudzaza, kuyika konyamula komanso kukonza pambuyo pake ndikugwiritsa ntchito zonse zimakhudzana mwachindunji pakugwira ntchito. Chifukwa chake, mu gawo la mapangidwe, gawo lopangira ndikugwiritsa ntchito kwamakasitomala ndikukonza gawo lagalimoto, kukonza koyenera komanso kokhazikika kuyenera kuchitidwa pamayendedwe kuti apewe zovuta zamagalimoto zomwe zimayambitsidwa ndi mayendedwe.

● Zida zapadera: zitsulo zazitsulo zosapanga dzimbiri zimalimbikitsidwa ngati ntchito yabwino yolimbana ndi dzimbiri ikufunika, kapena ngati ikugwira ntchito m'malo owonongeka monga madzi amchere;

● Chithandizo cha kutentha kwapamwamba: kutentha kwa ntchito ndikokwera kwambiri, ngati kupitirira madigiri a 150, kumafunika kutengera njira yopangira kutentha kwa kutentha kwa mphete. Madigiri 180 kapena madigiri 220, kapena madigiri 250 etc. amasankhidwa kwa chilengedwe.

● Chithandizo cha kuzizira: Pambuyo pozimitsa ndi musanatenthetse, onjezerani ndondomeko ya kuzizira pa kutentha kwapakati pa madigiri 70. Cholinga chachikulu ndikuchepetsa zomwe zili mu mphete ya austenite ndikuwongolera kukhazikika kwa mawonekedwe a bearing's dimensional.

Cholinga cha chisindikizo chonyamulira ndikuletsa kutuluka kwa mafuta mu gawo lonyamula, ndikuletsa fumbi lakunja, chinyezi, zinthu zakunja ndi zinthu zina zovulaza kuti zisalowe mkati mwa chonyamuliracho, kuti chonyamulacho chizitha kuyenda motetezeka komanso kosatha. pansi pa mikhalidwe yofunikira . M'mikhalidwe yotsatirayi, kusankha kwa ma bere osindikizidwa osindikizidwa kale ndi mafuta kungaperekedwe patsogolo.

●Kunyamula sikufunika kuti muziyenda mpaka kalekale.

● Pansi pa machitidwe ogwiritsira ntchito apakati ndi otsika liwiro, katundu ndi kutentha.

● Pamafunika mtengo wotsika popanga.

●Zigawo zomwe zimakhala zovuta kuwonjezera mafuta, kapena omwe safunikira kuwonjezera mafuta m'tsogolomu.

Pogwiritsira ntchito mtundu uwu, mapangidwe a chipolopolo chonyamula (bokosi) ndi chisindikizo chake chikhoza kukhala chosavuta, ndipo mtengo wopangira ukhoza kuchepetsedwa kwambiri: pamene zinthu zogwiritsira ntchito sizili zovuta, zimatha ngakhale kuthamanga kwa nthawi yaitali. Amagwiritsidwa ntchito kwambiri m'mafakitale monga zida zapakhomo, magalimoto, ndi ma mota. .

Kuphatikiza pa kugubuduza, mayendedwe a mpira wakuya amalumikizana kwambiri. Choncho, cholinga chachikulu cha kubereka ndi kuchepetsa kukangana ndi kuvala kwa mbali zosiyanasiyana za kubereka, komanso kupewa kusungunuka kwa kutentha. Kaya njira yothira mafuta ndi mafuta odzola ndi oyenera kapena ayi zidzakhudza kwambiri magwiridwe antchito ndi kulimba kwa zonyamula. Nthawi zambiri, mafuta ali ndi ntchito zotsatirazi.

● Chepetsani kukangana ndi kutha;

●Frictional kutentha conduction ndi kuchotsa Kutentha kopangidwa ndi kubala chifukwa cha mikangano kuyenera kuchitidwa kumalo ena kapena kuchotsedwa ndi mkhalapakati wa mafuta opangira mafuta, kuti kutentha kwa madontho onyamula, ndi mafuta ndi kunyamula kukhalebe kwautali. - nthawi ntchito.

●Kuchepetsa kupanikizika kwanuko.

Ma rolling bearings ndi zigawo zolondola ndipo ziyenera kukhazikitsidwa ndikugwiritsidwa ntchito moyenera. Pamene kubera kumayikidwa, mphete ya mating iyenera kutsindika, ndiko kuti, pamene kunyamula kumakanikizidwa pamtengo, mphete yamkati yazitsulo iyenera kutsindika, mwinamwake mphete yakunja ya kubereka iyenera kutsindika; ndipo pamene kusonkhana kwa shaft ndi chipinda chonyamulira kukhutitsidwa panthawi imodzimodzi, kunyamula kuyenera kutsimikiziridwa. Mphete zamkati ndi zakunja zimatsindikizidwa nthawi yomweyo. Pazifukwa zilizonse, khola lokhala ndi khola siliyenera kuperekedwa ndi mphamvu yakunja.

Phokoso la mayendedwe a mpira wakuya groove amatha kufalikira kudzera mumayendedwe amapangidwe kapena sing'anga ya mpweya. Mpira wozungulira wakuya womwe umadzinyamula wokha ndiye gwero la mawu kapena kugwedezeka. Kugwedezeka kapena phokoso la kubereka makamaka kumachokera ku kugwedezeka kwachilengedwe kwa kunyamula ndi kugwedezeka komwe kumapangidwa ndi kayendedwe kachibale mkati mwa chiberekero.

Kugwedezeka kwachilengedwe - mphete zamkati ndi zakunja za zokhala ndi mphete zokhala ndi mipanda yopyapyala, zomwe zimakhala ndi njira zawo zonjenjemera. Nthawi zambiri, ma frequency achilengedwe oyamba amayendedwe agalimoto amakhala pakati pa ma KHz ochepa.

Kugwedezeka kopangidwa ndi kusuntha kwachibale mkati mwa chimbalangondo - zenizeni zenizeni zenizeni za mphete zamkati ndi zakunja ndi malo a mpira wachitsulo, monga roughness ndi waviness, zomwe zingakhudze khalidwe la phokoso ndi kugwedezeka kwa chimbalangondo, pakati pawo chitsulo chachitsulo chimakhala ndi kukhudza kwakukulu.
