Ma cylindrical roller bearings amagubuduza opangidwa kuti azitha kunyamula katundu wambiri. Zinthu zazikuluzikulu zomwe zimagubuduza ndi ma cylindrical rollers omwe amalumikizana ndi mzere wothamanga. Mapangidwe awa amawapangitsa kukhala ogwira mtima kwambiri pakugwiritsa ntchito mphamvu zowoneka bwino za radial, zomwe zimakhala zofunikira kwambiri pamafakitale ambiri. Poyerekeza ndi mayendedwe a mpira omwe ali ndi kukula kofanana, amapereka mphamvu zonyamula ma radial apamwamba kwambiri.

Mapangidwe a Cylindrical Roller Bearings
- Mtundu wodzigudubuza wa cylindrical umakhala ndi zigawo zikuluzikulu izi:
- Mphete Yakunja:Nthawi zambiri amakhala ndi nthiti zokhazikika kapena ma flange mbali imodzi kapena mbali zonse kuti apereke chitsogozo cha axial kwa odzigudubuza.
- Mphete Yamkati:Komanso nthawi zambiri imakhala ndi nthiti kapena ma flanges owongolera ma roller. Kutengera kapangidwe kake, mphete yamkati imatha kukhala yophatikizika ndi nthiti kapena kupatukana (kuwongolera kukwera).
- Zodzigudubuza za Cylindrical:Precision-ground cylindrical rolling elements zomwe ndizomwe zimanyamula katundu. Kutalika kwa roller nthawi zambiri kumakhala kocheperako kuposa m'mimba mwake.
- Cage (Wosungira):Amalekanitsa odzigudubuza mofanana, kuwaletsa kuti asakhudze wina ndi mzake, ndikuwatsogolera molondola mkati mwa mipikisano. Zida za khola zimaphatikizapo chitsulo, mkuwa, kapena ma polima (mwachitsanzo, polyamide/nayiloni).
Makhalidwe a Cylindrical Roller Bearings
- Kuthekera Kwambiri kwa Ma Radial:Mapangidwe olumikizana ndi mizere amawathandiza kuti azigwira zonyamula ma radial apamwamba kwambiri kuposa ma fani ampira ofanana.
- High Radial Rigidity:Kuuma kwabwino kwambiri pamawonekedwe a radial, zomwe zimapangitsa kuti pakhale mapindikidwe ochepa pansi pa katundu.
- Low Friction:Kukana kugubuduza kochepa kumathandizira kuti pakhale mphamvu zambiri.
- Kuthamanga Kwambiri:Ma bere opangidwa bwino (makamaka okhala ndi mazenera opepuka) ndi oyenera kuthamanga kwambiri kozungulira.
- Kupatukana:Mitundu yambiri (mwachitsanzo, mapangidwe a NU, NJ) imakhala ndi mphete zolekanitsa (zamkati ndi/kapena zakunja), kuyika mosavuta, kutsika, ndi kukonza.
- Mphamvu Zochepa za Axial Load:Nthawi zambiri amatha kunyamula katundu wochepa kwambiri wa axial (kutengera kapangidwe ka nthiti), kapena kufunikira kophatikizana ndi ma axial mphamvu.
Kugwiritsa ntchito Cylindrical Roller Bearings
Ma cylindrical roller bearings amagwiritsidwa ntchito kwambiri pamapulogalamu omwe amafunikira kuchuluka kwa ma radial katundu ndi kukhazikika:
- Magetsi amagetsi ndi ma jenereta:Chithandizo cha rotor.
- Ma gearbox ndi Reducers:Thandizo la shaft ya gear.
- Rolling Mills:Mipukutu yogwira ntchito ndi zosunga zobwezeretsera.
- Mapampu ndi Compressors:Thandizo la shaft.
- Makanema Ogwedezeka:Kusamalira katundu vibratory.
- Makina Omanga:Kuwombera mphete muzofukula, cranes.
- Zopangira Mphepo:Main shaft bearings.
- Zida Zopangira Makina:Kumene kukhazikika kwakukulu ndi kulondola ndizofunikira.
- Makina Osindikizira:Thandizo la Cylinder.
Ma cylindrical roller amtundu wa premium amatsimikizira kudalirika kofunikira komwe kutha kwamphamvu kwa ma radial sikungakambirane.
