Kufotokozera Zamalonda
Ma cylindrical roller bearings ndi oyenerera bwino ntchito zokhala ndi zolemetsa zolemetsa komanso mphamvu zowoneka bwino. Ndi kulumikizana kwa mzere pakati pa odzigudubuza ndi ma raceways, ma bere awa amatha kunyamula katundu wokulirapo bwino. Chimodzi mwazabwino zawo zamapangidwe ndikupatukana kwa mphete zamkati ndi zakunja, zomwe zimathandizira kukwera ndi kuphatikizika.
Ma bere awa amapangidwa m'magulu angapo apangidwe, monga N, NU, NN, NNU, NJ, NF, NUP, ndi NH. Malingana ndi zofunikira zolemetsa ndi kuyika, ma cylindrical roller bearings amapezeka mu mzere umodzi, mizere iwiri, ndi mizere inayi.
Single Row Cylindrical Roller Bearing
Mzere umodzi wodzigudubuza wa cylindrical wodzigudubuza amadziwika chifukwa cha kukhazikika kwawo, mphamvu zazikulu zonyamula ma radial katundu komanso kusinthasintha kwachangu kwa ntchito. Mapangidwe ake osiyanasiyana amaphatikizapo mitundu yosiyanasiyana yodziwika bwino, yomwe mndandanda wa N, NJ, NU ndi NUP wakhala chisankho choyamba pamafakitale chifukwa cha kusiyana kwawo kwa nthiti.
| Chitsanzo | Kapangidwe ka m'mphepete | Axial udindo luso | Mawonekedwe |
| Mtundu wa NU | mphete yakunja imakhala ndi nthiti ziwiri zolimba, pomwe mphete yamkati ilibe nthiti | Palibe malo axial omwe amaperekedwa | Oyenera malo oyandama onyamulira, kulola kuti shaft ikule ndikulumikizana momasuka |
| Mtengo wa NUP | nthiti ziwiri zolimba mbali zonse ndi makina ochapira a nthiti otayirira pa mphete yamkati | pezani shaft mbali zonse ziwiri | Kusamuka kwa axis bidirectional kuti mukwaniritse malo enieni |
Chovala cha Double Row Cylindrical Roller Bearing
· Chifukwa cha mizere iwiri ya cylindrical roller bearings yonyamula katundu komanso kuuma kwake, mizere iwiri ya cylindrical roller bearings ndi yabwino kwambiri ponyamula katundu wolemetsa.
· Mapangidwe a ma cylindrical roller bearings a mizere iwiri amalola kusinthasintha kosavuta, komwe kumathandizira kukhazikitsa, kuchotsa, ndi kukonza mwachizolowezi kapena kuyendera.
· Mizere iwiri ya cylindrical roller bearings imapezeka nthawi zambiri pamapulogalamu ovuta kwambiri monga mphero, ma gearbox, ma shear a mbewu, ndi zida zamakina olondola, pomwe kulimba komanso kulondola ndikofunikira.
Four Row Cylindrical Roller Bearing
· Pokhala ndi zinthu zambiri zogubuduza, zonyamula zozungulira zinayi za mizere inayi zimamangidwa kuti zizitha kunyamula katundu wolemetsa kwambiri pamafakitale ovuta.
· Ma fani awa amapangidwa kuti azinyamula katundu wa radial okha ndipo samathandizira katundu wa axial paokha. Kuwongolera mphamvu za axial, nthawi zambiri amagwiritsidwa ntchito limodzi ndi mitundu ina ya mayendedwe-monga mayendedwe a mpira wakuya, mayendedwe amipira olumikizana, kapena mayendedwe odzigudubuza (mwina ma radial kapena thrust mitundu).
· Chifukwa cha mphamvu zawo zomanga ndi kunyamula katundu, zonyamula zodzigudubuza za mizere inayi zimagwiritsidwa ntchito makamaka pa ntchito zolemetsa, kuphatikizapo makina osindikizira, ma calender, ndi makina osindikizira.
Kugwiritsa ntchito Cylindrical Roller Bearings
Chifukwa cha uinjiniya wawo wokhazikika komanso kapangidwe kake kolimba, ma cylindrical roller bearings ndi abwino kwa mapulogalamu omwe amafunikira kuthamanga kwambiri komanso kutha kupirira katundu wolemetsa. Amagwiritsidwa ntchito kwambiri m'mafakitale monga kupanga zitsulo, kupanga magetsi, kupanga magalimoto, ndi magawo ena olemera a mafakitale.
Makamaka, mizere inayi ya cylindrical roller bearings nthawi zambiri imagwiritsidwa ntchito poyimitsira mphero, makina owerengera, ndi zida zosindikizira, pomwe mphamvu yayikulu yonyamula ma radial ndi kukhazikika kwa magwiridwe antchito ndikofunikira.
TP cylindrical roller bearings imapezeka mumiyeso yokhazikika komanso yokhazikika, ndipo timaperekanso mayankho a OEM/ODM potengera zojambula zaukadaulo kapena zofunikira pakugwiritsa ntchito.
