Lub plhaub bearing yog ib feem ntawm cov kabmob zawv zawg uas hu rau phau ntawv xov xwm. Nws yog ib nrab-cylindrical nto zoo li lub pobzeb, du heev, thiab feem ntau ua los ntawm hnav- cov ntaub ntawv tiv taus xws li tooj liab lossis los tiv thaiv- txhuam alloys. Hauv tshwj xeeb, nws tuaj yeem ua los ntawm ntoo, engineering yas, lossis roj hmab.
Bearing shells tuaj nyob rau hauv ob hom: integral thiab split. Integral bearing shells feem ntau hu ua bushings. Integral bearing shells muaj nyob nrog lossis tsis muaj roj grooves. Cov kabmob plhaub thiab phau ntawv xov xwm siv qhov kev sib tw kom haum thiab feem ntau tsis tig nrog cov ncej.
Thaum lub zawv zawg bearings ua haujlwm, cov roj nyias nyias yuav tsum tau nruab nrab ntawm cov kabmob thiab cov ncej rau lubrication. Yog tias lubrication tsis zoo, kev sib txhuam ncaj qha tshwm sim ntawm lub plhaub bearing thiab ncej. Qhov kev sib txhuam no ua rau muaj qhov kub thiab txias heev. Txawm hais tias lub plhaub bearing yog ua los ntawm tshwj xeeb siab - kub resistant alloy cov ntaub ntawv, lub siab kub generated los ntawm kev sib txhuam ncaj qha tseem txaus los hlawv nws tawm. Cov kabmob plhaub kuj tseem tuaj yeem hlawv tawm vim qhov hnyav dhau, kub dhau, impurities hauv cov roj lubricating, lossis txawv txav viscosity. Kev kub hnyiab tawm ntawm lub plhaub bearing ua rau tsis ua haujlwm ntawm cov kabmob zawv zawg.
