Mabearing otetezedwa: mdani wa shaft ya mota

Mu gawo laMa mota amagetsi a magawo atatu, vuto la mphamvu ya injini ya shaft ndi nkhani yodetsa nkhawa. Izi zitha kuyambitsa kuwonongeka msanga komanso kuwonongeka kwa zigawo za injini, makamaka ma bearing. Mwamwayi, ma bearing otetezedwa apezeka ngati yankho lamphamvu pa vutoli, ndikuchotsa bwino mphamvu ya injini ya shaft.

Kaya ndi ma bearing oteteza magetsi okhala ndi chophimba cha ceramic pa mphete yamkati kapena yakunja, kapena ma bearing osakanikirana a ceramic okhala ndi zinthu zozungulira za silicon nitride, mapangidwe atsopanowa adapangidwa kuti aletse kudutsa kwa magetsi. Mphamvu zoteteza magetsi za ma bearing awa ndizofunikira kwambiri poteteza umphumphu wa mota ndikuwonjezera nthawi yake yogwira ntchito.

Ma mota amagetsi oyambitsa magawo atatuNthawi zambiri amakumana ndi mafunde osochera chifukwa cha zinthu zosiyanasiyana, kuphatikizapo kusokonezeka kwa maginito ndi mavuto a nthaka. Mafunde awa akamayenda kudzera m'mabearing achizolowezi, amatha kuyambitsa maenje, ma grooves ndi kuwonongeka kwina, zomwe zimapangitsa kuti akonze zinthu mokwera mtengo komanso nthawi yopuma. Komabe, mabearing otetezedwa amapereka chotchinga chomwe chimatseka mafunde awa bwino, kuonetsetsa kuti injini ikuyenda bwino komanso moyenera.

Zophimba za ceramic zomwe zimagwiritsidwa ntchito mu ma bearing otetezedwa sizimangopereka chitetezo chamagetsi komanso zimawonjezera kukana kuwonongeka ndi dzimbiri. Ntchito ziwirizi zimapangitsa kuti zikhale zabwino kwambiri kugwiritsidwa ntchito m'malo ovuta komwe kuli kupsinjika kwamagetsi ndi makina. Momwemonso, ma bearing osakanikirana a ceramic ndi zinthu zawo zozungulira za silicon nitride zimaphatikiza ubwino wa zinthu zopepuka komanso kuuma kwapadera kuti ziwongolere magwiridwe antchito ndi kudalirika.

Pomaliza, ma bearing otetezedwa ndi omwe amasintha kwambiri polimbana ndi mafunde a shaft a mota. Mwa kugwiritsa ntchito ukadaulo wapamwamba uwu, mafakitale amatha kuteteza ma mota awo amagetsi, kuchepetsa ndalama zokonzera ndikuwonjezera magwiridwe antchito onse. Monga kufunikira kwa ma bearing odalirika komanso olimbaMagalimoto a magawo atatuMayankho akupitilira kukula, ma bearing otetezedwa mosakayikira adzakhala ndi gawo lofunika kwambiri pakupanga tsogolo la kapangidwe ka injini.
