Zvakafanana zvakavakwa sebhora mabearings, roller bearings ane line contact pane point contact, zvichiita kuti vakwanise hukuru uye kukwirira kuvhunduka.Iwo ma roller pachawo anouya mune akati wandei maumbirwo, anoti, cylindrical, spherical, tapered, uye tsono.Cylindrical roller bearings inobata chete mitoro yekusunda.Spherical roller bearings inogona kugarisa kusarongeka uye kusundidzira kwakawanda, uye, kana yapetwa kaviri, inosundira kune chero nzira.Tapered roller mabearings anogona kubata akakosha ekusundidzira mitoro.Tsono mabearings, akasiyana ecylindrical roller bearings, anogona kubata yakakwira radial mitoro yehukuru hwayo, uye inogona kugadzirwa seyetsono roller thrust bearings.

Roller mabheji anowanikwa seakazara-anokwanisa dhizaini uye tsono mabhengi anenge asingachinji anozove emhando iyi.Tsono mabhengi anonyanya kushanda nekudzokedzana, asi kukwesha kunenge kwakakwira nekuda kwe roller-against-roller rubbing.

Paunenge uchishandisa cylindrical roller bearings pane shafts ine angular misalignment, inosarudzwa kushandisa maviri mapfupi roller bearings kumashure-kumashure pane imwe yakareba roller bearing.

Kusarudza Bhora kana Roller Bearing
Semutemo wakajairwa, mabhengi ebhora anoshandiswa pakumhanya kwepamusoro uye mitoro yakareruka kupfuura mabheji anomonereka.Roller bearings anoita zvirinani pasi pekuvhunduka uye kukanganisa kurodha.

Mabhengi ebhora anowanzo tengeswa semagungano uye anongotsiviwa semayuniti.Maroller mabearings anogona kuwanzo patsanurwa uye anotakura ma roller nema rollers, kana ekunze kana emukati madzinza, anotsiviwa ega.Motokari dzemashure dzinoshandisa gadziriro dzakadaro kune mavhiri epamberi.Chakanakira dhizaini iyi ndechekuti mijaho inogona kunyungudutswa yakwana pamashafts uye mudzimba kugadzira magungano echigarire pasina kuisa njodzi kune ma roller pachawo.

Single-row bhora mabearings akajairwa uye anogona kushandiswa achichinjana pakati pevagadziri.Roller mabearings ane zvishoma-zvakajairwa zvakamisikidzwa saka anofananidzira anofanirwa kubvunza kabhuku kemugadziri kuti asarudze imwe yakakodzera application.

Rolling-element bearings inogadzirwa nehumwe chiyero chemukati.Chero kusarongeka kwese kunongobvisa bhora panzvimbo uye kubvisa iyi yemukati clearance haifanire kuve nemhedzisiro pahupenyu hweberengi.Roller bearings anonyanya kunzwa kune angular misalignment.Semuyenzaniso, bhora rinenge richimhanya zvine mwero nekumhanya kwakaringana ringashanda zvinobudirira nekumisikidza kwemakona kusvika pa 0.002 kusvika 0.004 in./in.pakati pekubereka uye shaft.A cylindrical roller inotakura, mukuenzanisa, inogona kunge iri mudambudziko kana kusarongeka kwakapfuura 0.001 in./in.Vagadziri vanowanzopa mutsara unogamuchirwa weangular misalignment kune avo ega mabearings.
