ASTM B271 C95500 tooj liab-raws li tus kheej-lubricating inlaid graphite bearings
ASTM B271 C95500 tooj liab-raws li tus kheej-lubricating inlaid graphite bearings yog tus kheej-lubricating thiab tu-dawb kiag li. Lawv yog tsim los ntawm ib tug centrifuge-cam khwb cia tooj liab alloy (ASTM B271 C95500), haum rau bearings nrog ib tug puab txoj kab uas hla ntau tshaj 180 hli, los yog ib tug tsis tu ncua nrum alloy (ASTM B505 C95500), haum rau bearings nrog ib tug puab txoj kab uas hla tsawg tshaj li 180 hli. . Nws yog hnav-resistant heev. Nws qhov chaw tiv tauj yog ntim nrog cov roj nplaum uas muaj cov graphite, thiab yog cov qauv raws li lub npe hu ua "macro faib txoj cai" thiab hom kev txav ntawm cov kabmob yuav ua haujlwm ntev. .
Cov bearings yog nruab nrog ib tug khiav-nyob rau hauv zaj duab xis ntawm 15 mus rau 20 µm, uas nws muaj nuj nqi yog xyuas kom meej tias cov khoom lubricant yog pauv mus rau mating khoom thaum lub sij hawm thawj lub zog.
Lawv yuav tsum muaj lub peev xwm zoo li qub thiab muaj zog, ruaj khov kev sib txhuam coefficient, tsis muaj "stick-slip" nyhuv, corrosion kuj, insensitivity rau av, thiab tsim nyog siv dej, roj los yog roj.
Rau cov kabmob uas muaj cov kab uas hla ntau dua 200mm, kev kam rau siab yuav tsum raug xam los ntawm peb pawg neeg ua haujlwm engineering raws li qhov tsis muaj ntawm txhua daim ntawv thov.
Koj daim ntawv thov tshwj xeeb yuav xav tau cov lus qhia tshwj xeeb rau kev teeb tsa.
