Angular Contact Ball Bearing

Mzere umodzi umodzi wolumikizana ndi mpira
Mzere umodzi umodzi wolumikizana ndi mpira umakhala ndi mphete yakunja, mphete yamkati, mzere wa mipira yachitsulo ndi khola. Mtundu woterewu ukhoza kunyamula katundu wa radial ndi axial katundu nthawi imodzi, komanso amatha kunyamula katundu wa axial, ndipo amatha kugwira ntchito mofulumira. Single mzere angular kukhudzana mpira mayendedwe akhoza kupirira axial katundu mbali imodzi. Mukayika ma radial katundu, mphamvu zowonjezera za axial zidzapangitsidwa, ndipo kusuntha kwa axial kwa shaft ndi nyumba kungathe kuchepetsedwa kumbali imodzi. Ngakhale kunyamula kotereku kumangonyamula katundu wa axial mbali imodzi, kumatha kuphatikizidwa ndi kunyamula kwina komwe kumanyamula katundu kwina. Ngati aikidwa awiriawiri, mapeto omwewo nkhope za mphete zakunja za mayendedwe awiri amatsutsana wina ndi mzake, mapeto aakulu akuyang'ana mbali zonse.
ndi nkhope (kumbuyo-kumbuyo DB), ndipo mapeto opapatiza akuyang'anizana ndi nkhope yopapatiza (yoyang'ana maso ndi maso DF), kuti asapangitse mphamvu yowonjezera ya axial, Komanso, shaft kapena nyumba ikhoza kungokhala pa axial play. mbali zonse ziwiri.

Mzere umodzi wa angular kukhudzana ndi mpira wokhala ndi mipira yambiri kuposa yakuya groove mpira wokhala ndi kukula kofanana, kotero kuti katundu wovotera ndi waukulu kwambiri mu mpirawo, kukhazikika kumakhalanso kolimba, ndipo ntchitoyo imakhala yokhazikika. Chilolezo cha radial chingasinthidwe ndi kusamuka kwapakati ndi mphete zakunja, ndipo ma seti angapo a mayendedwe amatha kulumikizidwa mofanana kuti apangitse kusokoneza chisanadze kuwongolera kukhazikika kwa dongosolo.
Kugwiritsiridwa ntchito kwa mayendedwe a mpira wa angular sikungatheke, ndipo luso lake lodzigwirizanitsa ndilochepa kwambiri.
Makhalidwe a mtundu uwu wa kubala ndi kuti kukhudzana ngodya si ziro, ndi muyezo kukhudzana ngodya mzere umodzi ang'ono kukhudzana mpira fani ndi 15 °, 25 °, 30 °, ndi 40 °. Kukula kwa ngodya yolumikizana kumatsimikizira mphamvu ya radial ndi axial mphamvu yomwe kubereka kumatha kupirira panthawi yogwira ntchito. Kukula kolumikizana ndi ngodya, ndikokulirapo kwa mphamvu ya axial yomwe imatha kupirira. Komabe, kamene kamakhala kakang'ono kolumikizana, ndikokomera kwambiri kuzungulira kothamanga kwambiri.
Mzere umodzi wolumikizira mpira umakhala wopanda chilolezo. Zokhazokha zomwe zasonkhanitsidwa ndi mpira wolumikizana ndizomwe zili ndi chilolezo chamkati. Malingana ndi zofunikira za malo ogwira ntchito, pali njira ziwiri zoperekera mayendedwe osonkhana: preload (preload) ndi preclearance (preset clearance). Chilolezo chamkati cha ma bearing a mpira omwe adadzaza kale ndi ziro kapena zoipa. Nthawi zambiri amagwiritsidwa ntchito pa spindle ya zida zamakina kuti apititse patsogolo kulimba komanso kulondola kwa kuzungulira kwa spindle. Chilolezo (preload) cha mayendedwe ang'onoang'ono olumikizana ndi mpira chasinthidwa musanachoke kufakitale, ndipo palibe kusintha kwa wosuta komwe kumafunikira. Waukulu m'lifupi kulolerana ndi mapeto nkhope protrusion wa wamba mzere umodzi ang'ono kukhudzana mpira mayendedwe amangopangidwa malinga ndi sukulu wamba, ndipo sangathe wowirikiza ndi kuphatikiza pa chifuniro.
Kupanga kwapadziko lonse lapansi komwe kumasonkhanitsidwa kolumikizana ndi mpira kungathe kusonkhanitsidwa mwanjira iliyonse, monga kumbuyo ndi kumbuyo, maso ndi maso kapena mndandanda. Pali njira ziwiri zoperekera zofananira zapadziko lonse lapansi: kutsitsa (preload) ndi preclearance (chilolezo chokhazikitsidwa). Kupatulapo mayendedwe osonkhanitsidwa padziko lonse lapansi, ma bere omwe ali mu mayendedwe ena ophatikizidwa sasinthana.
Mizere iwiri yolumikizana ndi mizere ya mpira
Mapangidwe a mizere iwiri yolumikizana ndi mizere yolumikizana ndi yofanana kwenikweni ndi ya mzere umodzi wolumikizana ndi mizere yolumikizana, koma imangotenga malo ochepa axial. Mizere iwiri yolumikizana ndi mizere yolumikizana imatha kupirira katundu wa radial ndi katundu wa axial kuchita mbali zonse ziwiri. Makonzedwe apamwamba okhwima amapezeka ndipo amatha kupirira mphindi zogubuduza.
Mzere umodzi wolumikizana ndi mipiringidzo yolumikizana ndi mipiringidzo yophatikizika yamakona
Pofuna kukonza kusasunthika ndi kunyamula katundu wa mayendedwe ang'onoang'ono a mpira, mayendedwe a mpira wa angular omwe ali ofanana nthawi zambiri amasonkhanitsidwa pawiri quadruple (QBCQFC, QT) kapena quintuple (PBC, PFC, PT, PBT, PFT) mawonekedwe. Pawiri pawiri ngodya kukhudzana mpira mayendedwe, njira makonzedwe agawidwa mitundu itatu: kumbuyo-kumbuyo (DB), maso ndi maso (DF), ndi tandem (DT). Mipira yobwerera kumbuyo ndi yoyenera kunyamula katundu wosiyana kapena wophatikizika wa radial ndi axial, ndipo imatha kupirira bidirectional axial load. Imatha kupirira mphindi yakugubuduza kwakukulu ndipo imakhala yolimba kwambiri. Ma preloads osiyanasiyana angagwiritsidwe ntchito molingana ndi momwe amagwirira ntchito. Mipira yolumikizana ndi maso ndi maso imakhala ndi mphindi zochepa zogubuduza ndipo imapereka kuuma kwa dongosolo. Ubwino wake ndikuti sichimakhudzidwa kwambiri ndi zolakwika za kukhazikika kwa nyumba. Angular kukhudzana mpira mayendedwe anakonza mndandanda amangololedwa kunyamula katundu axial lalikulu mbali imodzi. Nthawi zambiri, kasupe amagwiritsidwa ntchito poyika preload, ndipo kuchuluka kwa radial load yomwe ingathe kuthandizidwa ndi kuuma kwa bere kumadalira mtengo wosankhidwa.
