Yuav ua li cas xaiv marine bearing dej lubricating khoom?

Lub nkoj dov bearings feem ntau muaj lub nplhaib sab nraud, lub nplhaib puab, dov cov ntsiab lus thiab lub tawb. Hais lus nruj me ntsis, lawv yog tsim los ntawm cov nplhaib sab nraud, lub nplhaib puab, dov cov ntsiab lus, tawb, cov ntsaws ruaj ruaj thiab roj nplua nyeem. Rolling bearing tuaj yeem txhais tau tias yog cov kabmob dov feem ntau yog tsim los ntawm cov nplhaib sab nraud, lub nplhaib puab thiab cov khoom dov. Raws li cov duab ntawm cov khoom dov, dov bearings thiab cov menyuam bearings. Bearings yog ib feem tseem ceeb ntawm cov tshuab thiab khoom siv niaj hnub no. Nws lub luag haujlwm tseem ceeb yog txhawm rau txhawb lub tshuab tig lub cev, txo cov kev sib txhuam coefficient hauv kev txav, thiab xyuas kom raug. Raws li kev sib txhuam cov yam ntxwv ntawm kev txav mus los, cov kabmob tuaj yeem muab faib ua cov kabmob rolling thiab zawv zawg bearings. Ntawm cov bearings no, dov bearings tau tus qauv thiab serialized, tab sis piv nrog zawv zawg bearings, lawv radial qhov ntev, kev co thiab suab nrov yog ntau dua, thiab tus nqi siab dua.

Tieli ntoo yog ib txwm siv dej-lubricated bearing khoom rau nkoj. Ironwood yog tsim nyob rau hauv tropical cheeb tsam. Kev loj hlob qeeb, cov khoom zoo heev, siab hardness thiab loj feem. Nws yog nplua nuj nyob rau hauv resin thiab muaj cov yam ntxwv ntawm dej immersion kuj, corrosion kuj thiab puas kuj. Txawm li cas los xij, deformation thiab tawg yuav tshwm sim tom qab ziab. Ntxiv nrog rau cov ntoo thiab cov resin, hlau pear ntoo kuj muaj cov cob concentrates thiab lwm yam. Cov kua qaub latex tsim los ntawm cov phev thiab dej tuaj yeem txo qhov coefficient ntawm kev sib txhuam thiab ua kom lub neej ua haujlwm. Piv txwv li, kev sib txhuam coefficient ntawm kev sib txheeb ntawm kev txav hauv dej yog 0.003-0.007. Tsis tas li ntawd, qhov coefficient ntawm kev sib txhuam nce nrog qhov nce ntawm cov dej kub. Yog tias cov dej kub (kwv yees li 50 degrees Celsius) qis thiab cov ntsiab lus dej txaus, hlau ntoo muaj kev hnav zoo dua.

Cov hlau bar ( dav dav: 15mm-35mm, dav: 60mm-80mm, ntev: 150mm-300mm) yog nruj nreem kos rau hauv lub tes tsho bearing. Txhawm rau tiv thaiv qhov tsis zoo ntawm cov qauv strips, ob lossis peb lub tooj liab nres strips (thickness 60 feem pua ​​​​ntawm cov thickness ntawm cov hlau-ntoo sawb) yog ntsia nruab nrab ntawm lub puab nto ntawm bushings, thiab lawv yog tsau nrog bolts. Qhov qis ntawm lub bushing yog ntsug (qhov kev taw qhia fiber ntau yog perpendicular mus rau hauv nruab nrab kab ntawm tus ncej ncej), thiab sab sauv yog parallel (cov kev taw qhia fiber ntau yog perpendicular mus rau hauv nruab nrab kab ntawm tus Tsov tus tw ncej). V-shaped, U-shaped lossis trapezoidal tank tank yog tsim los ntawm cov phiaj los pab txhawb kev ncig ntawm cov dej hiav txwv rau lubrication thiab txias, tab sis tsis muaj dej tank rau qis ib nrab pobzeb 90.
