Pab
Kev npau taws rau tus kheej yog tsim nyog rau cov khoom hnyav hnyav thiab hnyav hnyav, kev seev suab, suab paj nruag qis, tsheb, maus taus, metallurgy, dov mills, mining, roj av, ntawv, cement, qab zib thiab lwm yam lag luam thiab kev siv tshuab.
Kev xav tau
Cov ntawv qhia kev ua haujlwm ntawm cov lus qhia:
1. Raws li hom dov bearing qauv
(1) Bearings yog cais ua raws li lawv cov lus qhia sib txawv los yog cov lus sib txuas nrog lub npe:
1) Radial Bearings - Feem ntau siv cov hlua khau uas tuav cov hlua radial nrog cov lus sib txuas ntawm 0 mus rau 45.
Raws li kev sib txawv nominal hu cov ces kaum, nws muab faib ua:
Radial tiv thaiv bearings - radial bearings nrog ib tug nominal hu rau kaum ntawm 0:
Concentric angular contact bearings - Centripetal bearings nrog ib lub npe nominal loj tshaj 0 txog 45.
2) Cov kabmob khawb-feem ntau yog siv rau txoj hlua kabmob nrog axial loads, nrog nominal kev sib ceg loj tshaj 45 txog 90.
Raws li kev sib txawv nominal hu cov ces kaum, nws muab faib ua:
Axial contact bearings - ntsev bearings nrog ib tug nominal hu rau kaum ntawm 90:
Axial angular contact bearings - ntsev bearings nrog ib lub npe hu loj tshaj 45 tiam sis tsawg dua 90.
(2) Bearings yog dej num raws li lawv hom ntawm lawv cov ntsiab lus:
1) Pob Bearings-Balls yog pob:
2) Cov menyuam kis las-rollers yog rollers. Raws li cov yeeb yam, cov menyuam kis tau yog muab faib rau:
Cylindrical roller bearings - ntxig cov ntsiab lus yog cylindrical roller bearings, qhov piv ntawm qhov ntev thiab txoj kab ntawm cov cylindrical roller tsawg dua los yog sib npaug rau 3;
Koob rau cov menyuam kabmob - cov kabmob khawm koob yog cov koob txhaj, qhov piv ntawm qhov ntev thiab txoj kab uas siv qhov koob txhaj tshuaj ntau dua 3, tiam sis lub taub yog tsawg dua los yog sib npaug li 5 hli;
Tapered roller bearings ---- rolling elements yog tapered roller bearings;
Spherical menyuam bearings yog kheej kheej kheej kheej kheej.
(3) Cov kabmob tuaj yeem hloov kho raws nws txoj haujlwm, muab faib ua:
1) Kev ntsuas nws tus kheej coj tus kheej ---- Lub raceway yog spherical thiab tuaj yeem hloov mus rau qhov kev nkag siab zoo thiab qhov pib ntawm ob lub voj voog;
2) Non-aligning bearings (nruj bearings) --- bearings uas tau deflect angular misalignment ntawm raceways.
(4) Raws li tus xov tooj ntawm cov kab ntawm dov ntsiab, qhov kev coj tus kheej yog muab faib ua:
1) ib leej kabmob - kev coj tus kheej nrog ib tug kab ntawm dov ntsiab;
2) Ob chav kab bearings - bearings nrog ob kab ntawm dov ntsiab;
3) Bearings-Bearings - Bearings nrog ntau tshaj ob kab ntawm dov ntsiab, xws li peb-kab, plaub-kab bearings.
(5) Cov Bearings yuav raug sib cais raws li lawv cov khoom, faib ua:
1) Cais tau cov kabmob ---- cov kabmob nrog cov khoom ntaiv;
2) Inseparable bearing ---- bearing tom qab qhov kawg kev them nyiaj yug, lub xov tooj ntawm caj npab tsis tuaj yeem tsis muaj kev cais cov kabmob.
