Kaviri Row Cylindrical Roller Bearings
Features
Mitsara miviri cylindrical roller bearings:
NN mhando: mhete yemukati ine mbabvu, uye mhete yekunze haina mbabvu. Mhete yekunze uye musangano wemukati unogona kuiswa zvakasiyana, izvo zvisingagadzirisi axial displacement ye shaft kana imba, uye haigoni kutakura axial mutoro. Kuenzaniswa nemutsara mumwe chete cylindrical roller inotakura saizi yakafanana yeradial, inogona kumira mikuru mikuru yeradial. Chimiro chacho chakabatana, deformation pasi pemutoro idiki, uye inonyanya kukodzera kutsigirwa kwespindle yemuchina wemuchina.
Nyora NN...K:
Chimiro chacho chakafanana nemhando yeNN, asi mukati megomba rekutakura rakaderedzwa, iro rakanakira kukwenenzverwa kweradial clearance yekutakura uye yakanakira kuungana uye disassembly. Iri rudzi rwekubereka rinonyanya kushandiswa muhombe shaft yemuchina wemuchina uye yakaiswa pane tapered shaft. Iyo radial clearance inogadziriswa nehuwandu hwekutsikirira kwemhete yemukati.
Type NNU, NNU…K:
Ring yekunze ine mbabvu uye yemukati haina mbabvu. Kune marudzi maviri emakomba ecylindrical uye conical makomba. Izvo hazvidzikisire axial displacement ye shaft kana imba uye haigone kutakura axial mitoro. Kuenzaniswa nemutsara mumwechete cylindrical roller inotakura saizi yakafanana yeradial, inogona kumira mikuru mikuru yeradial.
Nyora NNCF:
Ring yemukati ine mbabvu nhatu uye yekunze rin'i ine mbabvu imwe yekumisikidza axial mune imwe nzira. Ring yekunze inoiswa rin'i inochengetedza kune rumwe rutivi rwembabvu kuti irambe yakabereka muchidimbu chimwe.
NNCL mhando:
Ring yemukati ine mbabvu nhatu, mhete yekunze haina mbabvu, uye kune zvindori zvekumira pamativi ese kuti ive fani isingaparadzanisiki.
NNCS:
Mhete yemukati ine mbabvu nhatu, mhete yekunze haina mbabvu, uye pane yepakati yekuvhara mhete pakati pekunze kwekunze, iyo inova fani isingaparadzanisiki. Iyo shaft uye chigaro chekutakura chinobvumira imwe axial kusimuka uye inogona kushandiswa seyemahara yekupedzisira inotakura.
Applications
Mabheji akadai anonyanya kushandiswa mumashini ekushandisa maspindles, injini dzinopisa dzemukati, turbines gasi, zvinoderedza, kurodha uye kuburitsa michina uye akasiyana maindasitiri muchina.
Size range:
Mitsara miviri cylindrical roller bearings:
Mukati dhayamita saizi renji: 50mm ~ 1500mm
Okunze dhayamita saizi siyana: 80mm ~ 2300mm
Upamhi saizi renji: 23mm ~ 800mm
Kushivirira: Kurongeka kwechigadzirwa kune yakajairika giredhi, P6 giredhi, P5 giredhi, uye P4 giredhi zvigadzirwa zvinogona zvakare kugadziriswa kana mushandisi aine zvakakosha zvinodiwa.
Radial clearance
Iyo yakajairwa chigadzirwa chemitsetse miviri cylindrical roller bearing ine 1 seti yekucheneswa, uye cylindrical bore mabearings anogonawo kupa 2 kana 3 seti yemvumo.
Tapered bore bearings anowanikwawo ne 2 seti yemvumo.
Bearings ane radial clearance yakakura kana idiki pane yakajairwa kukosha inogona zvakare kugadzirwa zvinoenderana nezvinodiwa nemushandisi.
keji
Kaviri mutsara cylindrical roller mabheji anonyanya kushandisa macheji endarira emuchina, uye dzimwe nguva matanga enaironi anowanikwawo.
