Ndi zipangizo ziti zomwe zimagwiritsidwa ntchito popanga ma radial bearing?

 

Ma radial bearing, yomwe imadziwikanso kuti ma radial roller bearings, imagwiritsidwa ntchito makamaka kunyamula katundu wa radial. Ngodya yawo yokakamiza nthawi zambiri imakhala pakati pa madigiri 0 ndi 45.Mabeya a mpira wozunguliraamagwiritsidwa ntchito nthawi zambiri mu ntchito zothamanga kwambiri ndipo amakhala ndi mipira yolondola, khola, mphete zamkati ndi zakunja, ndi zina zotero. Maberiya awa amagwiritsidwa ntchito kwambiri mumakampani opanga makina, makampani opanga magalimoto, makampani opanga simenti ndi migodi, makampani opanga mankhwala, ndi makampani opanga zida zamagetsi.

 

Kuti zikwaniritse zofunikira pakugwiritsa ntchito zida za ma radial bearing, zipangizo zomwe zimagwiritsidwa ntchito popanga ziyenera kukhala ndi mphamvu yonyamula katundu, kukhazikika, kutentha, kusinthasintha kochepa komanso malo osalala, kukana kuwonongeka, kukana kutopa, komanso kukana dzimbiri. Pakadali pano, palibe chinthu chomwe chingakwaniritse zonsezi; chifukwa chake, njira zothetsera mavuto nthawi zambiri zimasankhidwa m'mapangidwe ambiri. Zipangizo zomwe zimagwiritsidwa ntchito kwambiri popanga ma radial bearing ndi izi:

 

Ma Bearing Alloys: Ma Bearing Alloys, omwe amadziwikanso kuti zitsulo za Babbitt, ndi ma Bearing Alloys omwe amagwiritsidwa ntchito kwambiri. Amatha kusintha mosavuta ku zolakwika zazing'ono kapena zolakwika mu shaft ndipo amatha kuyamwa zinyalala mu mafuta, zomwe zimapangitsa kuti shaft isagwedezeke.

 

Mkuwa: Ma bearing a mkuwa ndi oyenera kugwiritsa ntchito mofulumira komanso katundu wolemera komanso ntchito zomwe zimafuna kulinganizidwa bwino. Kugwira ntchito kwawo kungapezeke mwa kuwaphatikiza ndi zipangizo zosiyanasiyana kuti apange zinthu zosiyanasiyana.

 

Mkuwa Wopangidwa ndi Lead: Ma bearing opangidwa ndi mkuwa wopangidwa ndi lead ali ndi mphamvu zambiri zonyamula katundu kuposa ma alloy onyamula katundu, koma kusinthasintha kwawo ndi kochepa. Amagwiritsidwa ntchito m'malo omwe amafuna kulimba kwa shaft komanso kulinganiza bwino.

 

Chitsulo Chopangidwa: Ma bearing achitsulo chopangidwa nthawi zambiri amagwiritsidwa ntchito pazinthu zosavuta kugwiritsa ntchito. Komabe, kuuma kwa jenali kuyenera kukhala kwakukulu kuposa kwa bearing bush, ndipo malo ogwirira ntchito ayenera kuyendetsedwa mosamala pogwiritsa ntchito chisakanizo cha graphite ndi mafuta. Kugwirizana bwino pakati pa jenali ndi bearing ndikofunikira.

 

Ma Bearing Okhala ndi Mipata: Ma Bearing Okhala ndi Mipata amapangidwa ndi ufa wachitsulo wosungunuka ndikuuviika mu mafuta. Ali ndi mphamvu zodzipaka okha ndipo amagwiritsidwa ntchito makamaka pamene mafuta okhazikika ndi ovuta kapena osatheka.

 

Kaboni ndi Mapulasitiki: Ma bearing a kaboni oyera ndi oyenera kugwiritsidwa ntchito kutentha kwambiri kapena kugwiritsa ntchito komwe mafuta ndi ovuta kuwapaka. Ma bearing opangidwa ndi polytetrafluoroethylene (PTFE) ali ndi coefficient yotsika kwambiri ya kukangana, zomwe zimawalola kupirira kugwedezeka kwapakati ndi katundu wolemera pa liwiro lotsika, ngakhale popanda mafuta opaka.
