Momwemonso amapangidwa ngati mayendedwe a mpira, mayendedwe odzigudubuza amalumikizana ndi mzere m'malo molumikizana ndi mfundo, zomwe zimawathandiza kukhala ndi mphamvu zambiri komanso kukana kugwedezeka kwakukulu.Zodzigudubuza zokha zimabwera m'mawonekedwe angapo, monga, cylindrical, spherical, tapered, ndi singano.Ma cylindrical roller bearings amangoyendetsa zolemetsa zochepa.Zozungulira zozungulira zimatha kulolera molakwika ndi kukankhira kochulukirapo, ndipo, zikawirikiza, kukankhira mbali iliyonse.Mapiritsi odzigudubuza amatha kuyendetsa katundu wambiri.Zonyamula singano, zokhala ndi ma cylindrical roller bearings, zimatha kunyamula katundu wokulirapo wa kukula kwake, ndipo zitha kupangidwa ngati mayendedwe a singano.

Ma Roller Bearings amapezeka ngati mapangidwe okwanira komanso zonyamula singano nthawi zonse zimakhala zamtunduwu.Kunyamula singano kumakhala kothandiza kwambiri poyenda mobwerezabwereza, koma kukangana kumakhala kokulirapo chifukwa cha kusisita kwa ma roller-anti-roller.

Mukamagwiritsa ntchito ma cylindrical roller bearings pamiyendo yokhala ndi misalignment yokhota, ndibwino kugwiritsa ntchito ziboliboli ziwiri zazifupi kumbuyo ndi kumbuyo m'malo mokhala ndi chodzigudubuza chimodzi chachitali.

Kusankha Mpira kapena Roller Bearing
Monga lamulo, mayendedwe a mpira amagwiritsidwa ntchito pa liwiro lapamwamba ndi katundu wopepuka kuposa ma mayendedwe odzigudubuza.Ma Roller Bearings amachita bwino kwambiri akamagwedezeka komanso kukhathamiritsa.

Zonyamula mpira nthawi zambiri zimagulitsidwa ngati misonkhano ndipo zimangosinthidwa kukhala mayunitsi.Zimbalangondo zodzigudubuza nthawi zambiri zimatha kupasuka ndipo chonyamulira chodzigudubuza ndi zodzigudubuza, kapena mitundu yakunja kapena yamkati, m'malo mwake.Magalimoto oyendetsa kumbuyo amagwiritsira ntchito makonzedwe otere a mawilo akutsogolo.Ubwino wa kapangidwe kameneka ndikuti mitunduyo imatha kuphwanyidwa kuti ifike pamiyendo ndikukhala m'nyumba kuti apange misonkhano yokhazikika popanda kuwononga odzigudubuza okha.

Mizere ya mpira wa mzere umodzi imakhala yokhazikika ndipo imatha kugwiritsidwa ntchito mosiyana pakati pa opanga.Ma rola amakhala osakhazikika bwino kotero kuti wofotokozera amayenera kuyang'ana kalozera wa opanga kuti asankhe yoyenera kugwiritsa ntchito.

Mapiritsi a ma rolling amapangidwa ndi chilolezo chamkati.Kuyika kolakwika kulikonse komwe kumangosuntha mpira kuchoka pamalo ake ndikuchotsa chilolezo chamkatichi kusakhale ndi mphamvu pa moyo wa berelo.Zodzigudubuza zimakhudzidwa kwambiri ndi kusalinganika kwa angular.Mwachitsanzo, mpira wonyamula kuthamanga pa liwiro locheperako komanso womasuka kwambiri utha kugwira bwino ntchito ndi ma angle olakwika okwera mpaka 0.002 mpaka 0.004 in./in.pakati pa nthiti ndi shaft.Chozungulira chozungulira chozungulira, poyerekezera, chikhoza kukhala m'mavuto ngati kusalinganiza bwino kupitilira 0.001 in./in.Opanga nthawi zambiri apereka mitundu yovomerezeka ya ma angles olakwika pamayendedwe awo.
