Kodi ndi zipangizo ziti zomwe zimagwiritsidwa ntchito popanga ma radial bearing?

 

Ma radial bearing, omwe amadziwikanso kuti ma radial bearing, ndi mtundu wa bearing womwe umagwiritsidwa ntchito makamaka kunyamula katundu wa radial. Ngodya yodziyimira payokha nthawi zambiri imakhala pakati pa 0 ndi 45. Ma radial ball bearing nthawi zambiri amagwiritsidwa ntchito pazochitika zogwira ntchito mwachangu ndipo amapangidwa ndi mipira yolondola, ma cage, mphete zamkati ndi zakunja, ndi zina zotero. Mtundu uwu wa bearing wakhala ukugwiritsidwa ntchito kwambiri m'makampani opanga makina, magalimoto, migodi ya simenti, makampani opanga mankhwala ndi zida zamagetsi ndi madera ena.

 

Kuti zikwaniritse zofunikira pakugwira ntchito kwa ma radial bearing, zipangizo zomwe zimagwiritsidwa ntchito popanga ma radial bearing ziyenera kukhala ndi mphamvu yolimba yonyamula katundu, kukhazikika, kutentha koyenera, kupsinjika kochepa komanso malo osalala, kuletsa kutopa, kuletsa kutopa komanso kuletsa dzimbiri. Palibe zinthu zomwe zimakwaniritsa zofunikira zonse, kotero nthawi zambiri pamakhala mgwirizano m'mapangidwe ambiri. Zipangizo zomwe zimagwiritsidwa ntchito popanga ma radial bearing ndi izi:

 

Aloyi wopangira: Aloyi wopangira, yemwenso amadziwika kuti babbitt, ndiye aloyi wopangira omwe amagwiritsidwa ntchito kwambiri. Amatha kusintha mosavuta kuti agwirizane ndi zolakwika zazing'ono kapena ma shafts olakwika, ndipo amatha kuyamwa zinyalala mu mafuta kuti apewe kuwonongeka kwa guluu wa shaft.

 

Mkuwa: Ma bearing a mkuwa ndi oyenera kugwiritsidwa ntchito pa liwiro lotsika, lolemera komanso lopanda mphamvu, ndipo makhalidwe awo angapezeke powaphatikiza ndi zinthu zosiyanasiyana zokhala ndi zinthu zosiyanasiyana.

 

Mkuwa wa lead: chogwirira chopangidwa ndi mkuwa wa lead, mphamvu yake yonyamula ndi yokwera kuposa ya aloyi wonyamula, koma kusinthasintha kwake kudzakhala kochepa, ndipo chimagwiritsidwa ntchito m'malo okhala ndi kulimba kwabwino kwa shaft komanso pakati pabwino.

 

Chitsulo chopangidwa ndi chitsulo: Ma bearing achitsulo chopangidwa ndi chitsulo amagwiritsidwa ntchito kwambiri nthawi zina zosakhwima. Komabe, kuuma kwa jenali kumafunika kukhala kokwera kuposa kwa bearing, ndipo malo ogwirira ntchito ayenera kuyendetsedwa mosamala ndi chisakanizo cha graphite ndi mafuta, ndipo kulumikizana kwa jenali ndi bearing kuyenera kukhala bwino.

 

Maberiyani Obowoka: Maberiyani obowoka amapangidwa ndi ufa wachitsulo wosungunuka ndikuuviika mu mafuta, womwe umadzipaka wokha ndipo umagwiritsidwa ntchito makamaka m'malo omwe mafuta odalirika ndi ovuta kapena osatheka.

 

Kaboni ndi pulasitiki: Ma bearing a kaboni oyera ndi oyenera kugwiritsidwa ntchito kutentha kwambiri kapena kugwiritsa ntchito komwe mafuta ndi ovuta, pomwe ma bearing opangidwa ndi PTFE ali ndi coefficient yotsika kwambiri ya kukangana ndipo amatha kupirira kugwedezeka kwakanthawi ndi katundu wolemera pa liwiro lotsika, ngakhale akamagwira ntchito popanda mafuta.
