Njira zosinthira mavuto pambuyo pokhazikitsa ma bere

Mukayika, musamenyetse mwachindunji mbali ya bearing end ndi malo osapanikizika. Makina osindikizira, chigoba kapena zida zina zoyikira ziyenera kugwiritsidwa ntchito kuti bearing bearing bear ikhale ndi mphamvu yofanana. Musayike ndi thupi lozungulira. Ngati malo oyikapo apakidwa mafuta, izi zipangitsa kuti malowo akhale osalala. Ngati kusokoneza koyenera kuli kwakukulu, bearing iyenera kutenthedwa kufika 80 ~ 90℃ mu mafuta amchere ndikuyiyika mwachangu momwe mungathere, samalani kutentha kwa mafuta osapitirira 100℃, kuti mupewe kuchepetsa kuuma kwa kutentha ndikukhudza kuchira kwa kukula. Mukakumana ndi zovuta pakuchotsa, tikukulimbikitsani kuti mugwiritse ntchito chida chochotsera kuti mutulutse kunja mukutsanulira mafuta otentha mosamala pa mphete yamkati, kutentha kudzapangitsa mphete yamkati ya bearing kukula, kuti ikhale yosavuta kugwa.

Si ma bearing onse omwe amafuna chilolezo chochepa chogwirira ntchito, muyenera kusankha chilolezo choyenera malinga ndi zomwe zili. Mu muyezo wa dziko lonse 4604-93, chilolezo cha radial cha ma rolling bearing chimagawidwa m'magulu asanu: gulu lachiwiri, gulu la 0, gulu lachitatu, gulu lachinayi ndi gulu lachisanu. Ma clearance amachokera pang'ono mpaka lalikulu, ndipo gulu la 0 ndiye chilolezo chokhazikika. Gulu loyambira la radial clearance ndiloyenera kugwiritsidwa ntchito nthawi zonse, kutentha kwachizolowezi komanso kusakanikirana kofala; clearance yayikulu ya radial iyenera kusankhidwa ya ma bearing omwe amagwira ntchito pansi pazikhalidwe zapadera monga kutentha kwambiri, liwiro lalikulu, phokoso lochepa komanso kukangana kochepa. clearance yaying'ono ya radial iyenera kusankhidwa ya ma spindle olondola ndi ma spindle a zida zamakina; clearance yaying'ono yogwirira ntchito ikhoza kusungidwa ya ma roller bearing. Kuphatikiza apo, palibe clearance ya bearing yolekanitsidwa; Pomaliza, clearance yogwira ntchito ya bearing pambuyo poyiyika iyenera kukhala yaying'ono kuposa clearance yoyambirira musanayike, chifukwa bearing iyenera kukhala ndi kuzungulira kwina kwa katundu, komanso kusintha kwa elastic komwe kumachitika chifukwa cha covering fit ndi load.

Poganizira vuto la vuto la kutseka ma bearing ndi kutseka kokhala ndi inlay, pali njira ziwiri zomwe ziyenera kutsatiridwa mosamala pokonza.

1. Kapangidwe ka chivundikiro cha bearing chotsekedwa bwino kamasinthidwa mbali zonse ziwiri za bearing, ndipo kapangidwe ka bearing kamasinthidwa kuchokera ku zida. Kukhudzana mwachindunji ndi bearing sikofunikira, ndipo bearing ndi yotetezeka ku fumbi kuchokera kunja kwa bearing. Mphamvu yotsekera ya kapangidwe kameneka ndi yayikulu kuposa ya bearing yokha yomwe imagulitsidwa ndi bearing agent, yomwe imatseka mwachindunji njira yolowera ya zinthu zopyapyala ndikuwonetsetsa kuti mkati mwa bearing mumakhala oyera. Kapangidwe kameneka kamawongolera malo otenthetsera kutentha kwa bearing ndipo sikuwononga kwambiri magwiridwe antchito a bearing.

2. Ngakhale njira yotsekera yakunja ya bereji ili ndi mphamvu yabwino yotsekera, njira yochotsera kutentha nayonso imatsekedwa, kotero zigawo zoziziritsira ziyenera kuyikidwa. Chipangizo choziziritsira chikhoza kuchepetsa kutentha kwa mafuta odzola, ndipo ntchito yotentha kwambiri ya bereji ikhoza kupewedwa kudzera mu kuchotsera kutentha kwachilengedwe pambuyo pozizira.
