Dab tsi yog Low-Kub Bearing

Ib lub bearing uas kub qis tsis yog hais txog ib lub bearing uas ua haujlwm ruaj khov hauv qhov chaw kub siab (piv raucov kabmob kub siab), tab sis yog ib lub bearing tsim los ntawm cov ntaub ntawv tshwj xeeb thiab cov qauv tsim los txo qhov sib txhuam coefficient, yog li txo qhov kub ntawm kev sib txhuam. Qhov no tso cai rau lub bearing kom tswj tau qhov kub qis txawm tias thaum lub sijhawm ua haujlwm ntev.

 

Cov kabmobnrog rau qhov kub ua haujlwm qis dua -60 ℃ suav tias yog cov kabmob kub qis. Lawv feem ntau siv rau hauv ntau yam twj tso kua, xws li cov twj tso kua roj liquefied natural, cov twj tso kua nitrogen (hydrogen, oxygen), cov twj tso kua butane, cov twj tso kua rau rockets thiab missiles, spacecraft, thiab lwm yam.

 

Kev Ua Haujlwm Kub ntawm Cov Bearings Kub Qis

Qhov kub ua haujlwm ntawm cov kabmob uas kub qis qhia txog cov khoom siv thev naus laus zis thiab qib kev tsim khoom ntawm cov kabmob. Nws feem ntau ntsuas los ntawm qhov sib txawv ntawm qhov kub ntawm lub nplhaib sab nraud ntawm cov kabmob thiab cov roj txias uas txhaj thaum lub sijhawm ua haujlwm. Qhov kub ua haujlwm qis dua txhais tau tias lub neej ua haujlwm ntev dua thiab kev ua haujlwm zoo dua.

 

Pawg ntawm Cov Bearings Kub Qis

Cov kabmob kub qis feem ntau yog ib kab sib sib zog nqus pob bearings thiab cylindrical roller bearings.

 

Raucov kabmobThaum muaj kev qaug dab peg ntawm qhov kub qis, qhov tseem ceeb sab nraud yog qhov hloov pauv kub, thaum qhov tseem ceeb sab hauv yog cov coefficients thermal expansion sib txawv ntawm tus ncej, thav duab, thiab cov ntaub ntawv. Thaum qhov kub ntau, cov ntaub ntawv sib txawv ntsws ntawm cov nqi sib txawv, txo qhov chaw thiab ua rau jamming. Yog li ntawd, rau cov khoom siv nrog ntau qhov kev ua haujlwm, suav nrog cov khoom siv siv hauv qhov kub qis, nws yog qhov tsim nyog los xam cov coefficients nthuav dav ntawm cov ntaub ntawv thiab, qhov twg ua tau, siv cov ntaub ntawv nrog cov coefficients nthuav dav zoo sib xws rau cov txiaj ntsig zoo dua.

 

Tsis tas li ntawd xwb, thaum tsim qauv, nws raug nquahu kom tsis txhob siv cov kabmob conical roller bearing ntawm txhua qhov kawg ntawm tus ncej. Hauv cov qauv zoo li no, qhov ntev ntawm ob lub bearings, qhov ntau dua qhov muaj feem yuav jamming. Yog tias ob lub tapered bearings raug ntsia rau ntawm ib qho kawg ntawm tus ncej, lawv tuaj yeem ua haujlwm ua tus ncej, txwv kev txav axial. Qhov kawg ntawm tus ncej, siv nrog lub dov bearing, tsuas yog txwv cov zog radial, tso cai rau kev txav axial txwv nrog rau kev hloov pauv kub axial.

 

Kev Xaiv Khoom Siv Rau Cov Bearings Kub Qis

Kev Xaiv Cov Hlau Bearing rau Cov Bearings Kub Qis

Cov kabmob kub qis feem ntau yog ua los ntawm cov hlau tsis xeb 9Cr18 lossis 9Cr18Mo, thiab kuj tuaj yeem ua los ntawm beryllium bronze, ceramics, thiab lwm yam khoom siv. Hauv qab qhov kub ua haujlwm qis heev (kub heev -253 ℃), yog tias qhov txwv ua haujlwm xav tau -253 ℃, 6Cr14Mo cov khoom siv tuaj yeem xaiv tab sis yuav tsum tau siv rau hauv qhov chaw nqus tsev.

 

Thaum siv cov bearings uas kub tsawg, yuav tsum tau saib xyuas cov teeb meem xws li overheating los ntawm kev tsis muaj lubrication zoo, yog li nws yog ib qho tseem ceeb uas yuav tsum xaiv cov roj nplua nyeem uas tsim nyog.
