Mphete yokhazikika MTE19201216
Mphete yokhazikika ndi gawo lofunika kwambiri la chitetezo ndi chitetezo lomwe limagwiritsidwa ntchito kwambiri m'mafakitale ndi magetsi osiyanasiyana, ndipo ntchito yake yayikulu imayang'ana kwambiri kuchepetsa zoopsa zamagetsi zomwe zingasokoneze umphumphu wa zida ndi chitetezo chogwira ntchito. Ntchito yake yayikulu yopatutsa mafunde otuluka ndi yosiyana kwambiri kuposa kusuntha kwa mafunde otuluka - mafunde otuluka, omwe nthawi zambiri amabwera chifukwa cha kuwonongeka kwa matenthedwe, kuwonongeka kwa zigawo, kapena zolakwika zamagetsi zosayembekezereka m'makina monga ma mota, majenereta, kapena zida zamagetsi zamphamvu, zimayambitsa zoopsa zazikulu ngati sizingathetsedwe. Mafunde otayika awa sangangoyambitsa machenjezo abodza m'makina owunikira komanso angayambitse kutentha kwambiri kwa zigawo zamagetsi, kuwonongeka kwa matenthedwe mwachangu, komanso zoopsa zamoto zomwe zingachitike. Mphete yokhazikika imagwira ntchito ngati njira yodzipereka, yolimba ya mafunde otuluka awa, kuwatsogolera mosamala pansi kapena makina okhazikika m'malo mowalola kuti ayende m'njira zosayembekezereka (monga zotchingira zitsulo, mawaya, kapena zida zapafupi), motero kuteteza makina amagetsi okha ndi antchito omwe angakhudze malo owonekera.
Mphete yokhazikika imathetsa vutoli mwa kukhazikitsa kulumikizana kwamagetsi kolunjika, kotsika, pakati pa shaft yozungulira ndi chimango chosasuntha cha chipangizocho (kapena makina okhazikika). Mwa kupereka njira yodzipereka iyi, mphete yokhazikika imalinganiza bwino mphamvu zamagetsi kudutsa shaft ndi ma bearing, kuletsa kusonkhana kwa magetsi a shaft omwe angayambitse ma bearing currents oopsa. Ntchito yoteteza iyi ndi yofunika kwambiri pamachitidwe amagetsi ogwira ntchito kwambiri kapena amphamvu kwambiri—monga omwe amagwiritsidwa ntchito popanga, kupanga magetsi, kapena makina olemera—kumene ngakhale kuwonongeka pang'ono kwa ma bearing kumatha kubweretsa kusokonekera kwakukulu kwa ntchito kapena zoopsa zachitetezo.
