Ma rolling bearings ali ndi zisindikizo zoyankhira mbali zonse ziwiri.Ndi chivundikiro cha fumbi ndi chisindikizo, machitidwe awiri osiyana, amodzi ndi umboni wa fumbi, wina amasindikizidwa.Chisindikizo ndi kupanga kubala mkati mafuta (mafuta) ntchito ndondomeko sataya, kunja mafuta odetsedwa si kophweka inflow, kuonetsetsa kuti kubala mu boma afewetsedwa;denga la fumbi ndi kuteteza kunja kwa chimbalangondo ku fumbi kapena mpweya woipa kulowa m'bowolo, kuti muteteze kuwonongeka.
Chibakera.kubala ndi kusindikiza
M'zaka zaposachedwa, ma bearings ali ndi zida zosindikizira.M'mbuyomu, ma bearings ndi otseguka.Pofuna kuonetsetsa kuti mafuta ndi kutsimikizira fumbi la ma bearings, zida zosindikizira zidayikidwa pazitsulo kumapeto kwa mayendedwe.Ndi chitukuko cha mafakitale, makamaka makampani chakudya, kutchuka kwa makina amakono ofesi ndi zipangizo kunyumba amafuna yaying'ono zipangizo zipangizo kuchepetsa kulemera ndi kupewa anayi odzigudubuza osagwirizana chisindikizo kutayikira ndi mayendedwe mpweya kutayikira.Izi zikutanthauza kuti ma bearingswo ali ndi zida zosindikizira.
Nthawi zambiri pamakhala zosindikizira za mphira kapena zauinjiniya, ndi zisindikizo zachitsulo (kapena zipewa zafumbi).Mphete zosindikizira zimapezeka mumitundu yosiyanasiyana yosindikiza, yokhala ndi zotsatira zosiyana zosindikiza.Ngati pali kusiyana pakati pa chisindikizo ndi shaft, izi zimatchedwa chisindikizo chosalumikizana.Chilolezo chaching'ono, chimapangitsa kuti chisindikizo chikhale bwino, koma chimachepetsa kuthamanga kwa shaft yololedwa;ndi mosemphanitsa.Ngati palibe chilolezo pakati pa chisindikizo ndi shaft yozungulira, imatchedwa chisindikizo cholumikizira.Kukula kwa malo okhudzana ndi milomo yosindikiza chisindikizo, kumapangitsanso kusindikiza bwino, koma kutsika kwa liwiro la shaft, ndi mosemphanitsa.
Chachiwiri, kunyamula fumbi umboni kusindikiza njira mawu
Umboni wa fumbi ndi Z adati, kusindikiza ndi S adati (chisindikizo cha mphete ndi FS chinati; chisindikizo cha rabara ndi LS chinati).
1.Chivundikiro cha fumbi
Kusunga mphete yamtundu wazitsulo yokhala ndi chivundikiro cha fumbi, ya mayendedwe ang'onoang'ono, kupondaponda chitsulo mbale yokhala ndi mphete yolimba ya masika yokhazikika pamapangidwe akunja a mphete.
Sitampu zitsulo mbale yokhala ndi chivundikiro fumbi, kuchepetsa mafuta seepage, zitsulo mbale zitsulo mu mphete yakunja sitampu kulimbitsa dongosolo.
2.Kusindikiza mphete
Kusunga mphete yamtundu wa Teflon yokhala ndi chisindikizo, yomwe imagwiritsidwa ntchito makamaka ngati mayendedwe ang'onoang'ono.Mphete yakunja yokhala ndi ulusi wagalasi Teflon yosindikiza mphete, yokhala ndi mphete yolimba ya masika.
Kulumikizana ndi mphira wokhala ndi chisindikizo, kuteteza bwino kulowerera kwa thupi lakunja.Chisindikizo cha rabara chimayikidwa mu mphete yakunja ya bere ndipo chisindikizocho chimalumikizana ndi mphete yamkati.
Malingana ndi malo enieni omwe zitsulo ndi zisindikizo zimagwiritsidwa ntchito, zipangizo zomwe zimagwiritsidwa ntchito popanga fumbi ndi zisindikizo zimasiyana.
