Cylindrical Roller Bearing Nj Nu Nup
Mwachidule
Ma cylindrical rollers ndi raceways ndi mizere yolumikizana.Kuchuluka kwa katundu, makamaka kunyamula katundu wa radial.Kukangana pakati pa chinthu chogubuduza ndi nthiti ya mphete ndi yaying'ono, yomwe ili yoyenera kusinthasintha kothamanga kwambiri.Malingana ndi ngati mpheteyo ili ndi nthiti kapena ayi, ikhoza kugawidwa m'mizere imodzi ya cylindrical roller bearings monga NU, NJ, NUP, N, NF, ndi mizere iwiri ya cylindrical roller bearings monga NNU ndi NN.Kunyamula ndi dongosolo lomwe mphete yamkati ndi mphete yakunja imatha kulekanitsidwa.
Zilonda za cylindrical roller popanda nthiti pa mphete yamkati kapena yakunja, mphete zamkati ndi zakunja zimatha kuyenda molingana ndi malangizo a axial, kotero angagwiritsidwe ntchito ngati mayendedwe omasuka.Miyendo ya Cylindrical roller yokhala ndi nthiti ziwiri kumbali imodzi ya mphete yamkati ndi mphete yakunja ndi nthiti imodzi kumbali ina ya mpheteyo imatha kupirira mlingo wina wa axial katundu kumbali imodzi.Nthawi zambiri, khola lachitsulo limagwiritsidwa ntchito, kapena aloyi yamkuwa yotembenuza khola lolimba imagwiritsidwa ntchito.Komabe, palinso gawo la ntchito ya polyamide kupanga khola.
Gwiritsani ntchito
Ma motors amagetsi akulu ndi apakatikati, zotchingira zida zamakina, ma injini oyatsira mkati, ma jenereta, ma turbine a gasi, ma gearbox, mphero zogudubuza, zowonera zonjenjemera, ndikukweza ndi kunyamula makina, ndi zina zambiri.
Kapangidwe
1. Lembani N0000 popanda nthiti pa mphete yakunja ndikulemba NU0000 popanda nthiti pa mphete yamkati.Mapiritsi a cylindrical roller amatha kuvomereza katundu wamkulu wa radial, ali ndi malire othamanga kwambiri, samamanga axial kusamutsidwa kwa shaft kapena nyumba, ndipo sangathe kuvomereza axial katundu.
2. Mapiritsi a cylindrical roller NJ0000 ndi NF0000 okhala ndi nthiti pazitsulo zonse zamkati ndi zakunja amatha kuletsa kusuntha kwa axial kwa shaft kapena nyumba kumbali imodzi, ndipo akhoza kuvomereza kachidutswa kakang'ono ka axial.NU0000 + HJ0000, NJ0000 + HJ0000, ndi mayendedwe a NUP0000 amatha kuletsa kusuntha kwa axial kwa shaft kapena nyumba m'njira ziwiri mkati mwa dera la axial clearance la zotengera zomwe zimatumizidwa kunja, ndipo zimatha kuvomereza zonyamula zing'onozing'ono za axial.
