Zojambula za Cylindrical Roller Bearings

Mtundu uwu wa mayendedwe a mpira uli ndi njira ziwiri zothamanga mkati ndi wamba ozungulira mpikisano mu mphete yakunja. Ili ndi katundu wodzipangira okha. pomwe kusalongosoka komwe kunabwera chifukwa cha zolakwika pakukweza kapena kupotokola kwa shaft.

Ma cylindrical roller ndi raceway ndi mizere yolumikizana ndi mizere yonyamula katundu wambiri, makamaka yonyamula katundu wa radial. Kukangana pakati pa chinthu chogudubuza ndi m'mphepete mwa mphete ndi kakang'ono. Oyenera kusinthasintha kothamanga kwambiri.

Malinga ndi kupezeka kapena kusapezeka kwa m'mphepete mwa mphete, pali mizere imodzi monga NU, NJ, NUP, N, NF, ndi mizere iwiri monga NNU ndi NN.

Chovala ichi ndi chomangika cholekanitsidwa chokhala ndi mphete zamkati ndi zakunja.

Chovala cha cylindrical chodzigudubuza chopanda malire chosungira mkati kapena kunja kwa mphete chingagwiritsidwe ntchito ngati mapeto aulere chifukwa cha kayendedwe kake ka mkati ndi kunja kwa mphete za axial. Mphepete mwa cylindrical wodzigudubuza wokhala ndi m'mphepete mwawiri wosungira mbali imodzi ya mphete yamkati kapena yakunja ndi m'mphepete umodzi wotsalira kumbali ina ya mpheteyo imatha kupirira mlingo wina wa axial katundu kumbali imodzi.

Mizere iwiri ya cylindrical roller bearings imakhala yolimba kwambiri motsutsana ndi katundu wa radial ndipo imagwiritsidwa ntchito makamaka ngati ma spindle a zida zamakina.

Nthawi zambiri, mazenera opangidwa ndi chitsulo chosindikizira kapena makola opangidwa ndi copper alloy amagwiritsidwa ntchito. Koma palinso gawo lomwe limagwiritsa ntchito makola opangidwa ndi polyamide.

Ma bearings amapangidwa ndi kukhudzana kwa mzere pakati pa odzigudubuza ndi raceways.Zomwe zitha kugwiritsidwa ntchito kunyamula katundu wokulirapo kwambiri ndipo zitha kuloledwa kuzungulira mothamanga kwambiri mu gerral. kapena nthiti yakunja imagwiridwa pamodzi ndi khola kuti apange gulu lomwe lingathe kuchotsedwa ku mphete zina komanso lomwe lili ndi nthiti imodzi kapena yopanda nthiti, ndilosavuta kukwera ndi kutsika. Zingwe zokhala ndi mphete zamkati ndi mphete zakunja zonse zokhala ndi nthiti zitha kugwiritsidwa ntchito kunyamula katundu wina wa axial ndikuletsa kusuntha kwa axial kwa tsinde kapena nyumba kumbali imodzi kapena mbali zonse.

Mizere iwiri ya cylindrical roller (mtundu wa NN3000k) yokhala ndi tapered bore (1:12) ndi yonyamula katundu wokulirapo komanso wokhazikika.
