Heavy-duty tsheb bearings

Cov tsheb hnyav hnyav yuav tsum muaj cov kabmob zoo kom ntseeg tau tias lawv ua tau zoo thiab nyab xeeb. Muaj ntau hom kabmob uas siv rau hauv cov tsheb hnyav, txhua tus tsim los tswj cov kev thauj khoom tshwj xeeb thiab nrawm. Ntawm no yog ib daim ntawv teev cov feem ntau siv hom nrog rau lawv specifications:

1. Tapered roller bearings (TRBs) - TRBs tuaj yeem tswj tau ob qho tib si radial thiab axial loads thiab feem ntau yog siv rau hauv log bearings rau tsheb thauj khoom thiab tsheb npav. Lawv yog tsim los ntawm ob lub khob thiab lub khob hliav qab, nrog lub khob nyob rau hauv lub nplhaib sab nrauv thiab lub khob hliav qab nyob rau hauv lub nplhaib puab. Lub kaum sab xis ntawm lub khob hliav qab yog tsim los tuav lub zog tawm ntawm cov kabmob thaum lub sijhawm braking thiab acceleration.

2. Pob bearings - Pob bearings feem ntau yog siv rau hauv lub kauj thiab lub log bearings rau tsheb, tsheb thauj khoom, thiab tsheb npav. Lawv tuaj yeem tuav ob qho tib si radial thiab axial loads thiab muaj kev saib xyuas qis. Lawv muaj ib lub nplhaib sab nraud, lub nplhaib sab hauv, thiab ib pawg ntawm cov pob uas yob ntawm lub nplhaib.

3. Cylindrical roller bearings (CRBs) - CRBs yog siv rau hauv cov khoom siv hnyav xws li mining, kev tsim kho, thiab kev ua liaj ua teb. Lawv tsuas muaj peev xwm tuav tau radial loads, tab sis lawv muaj peev xwm tuav tau ntau dua loads dua pob bearings. Lawv yog tsim los ntawm ob peb lub cylindrical rollers teem ib ncig ntawm lub hauv paus axis thiab feem ntau yog siv nyob rau hauv gearboxes, traction motors, thiab engine compressors.

4. Spherical roller bearings (SRBs) - SRBs yog siv rau hauv cov ntawv thov uas cov kabmob yuav tsum sib dhos nws tus kheej kom tswj tau qhov tsis zoo tshwm sim los ntawm cov ncej deflection lossis mounting yuam kev. Lawv feem ntau siv nyob rau hauv axles, gearboxes, thiab conveyor systems. Lawv muaj peev xwm tuav tau ob qho tib si radial thiab axial loads thiab muaj tus kheej-aligning tsim uas tuaj yeem lis misalignment mus txog 3 degrees.

5. Needle roller bearings (NRBs) - NRBs yog siv rau hauv cov ntawv thov uas qhov chaw muaj kev txwv, thiab cov load kuj yog lub teeb. Lawv muaj cov txheej txheem ntawm cov menyuam yaus uas nyias nyias thiab cylindrical, ua rau lawv zoo tagnrho rau kev siv qhov chaw nyob ntawm tus nqi. Lawv feem ntau siv nyob rau hauv kev sib kis, roj twj, thiab rocker caj npab pivots.

Cov kev qhia tshwj xeeb ntawm cov kabmob no txawv nyob ntawm daim ntawv thov, tab sis qee qhov kev qhia dav dav suav nrog:

- Loj: Qhov loj ntawm cov kabmob yog hais txog nws sab hauv thiab sab nraud diameters thiab dav.
- Khoom siv: Cov khoom siv los tsim cov kabmob plays lub luag haujlwm tseem ceeb hauv nws cov kav ntev thiab kev ua haujlwm. Cov khoom siv feem ntau suav nrog chrome steel, carbon steel, thiab stainless hlau.
- Lub peev xwm thauj khoom: Lub peev xwm thauj khoom ntawm cov kabmob hais txog qhov hnyav uas nws tuaj yeem ua haujlwm yam tsis muaj deforming lossis ua tsis tiav.
- Kev ntsuas ceev: Kev ntsuas ceev ntawm cov kabmob yog hais txog qhov siab tshaj plaws kev sib hloov ceev uas nws tuaj yeem ua haujlwm yam tsis muaj kev hnav lossis kev puas tsuaj ntau dhau.
- Lubrication: Lub lubrication zoo yog qhov tseem ceeb rau lub neej ntev thiab kev ua haujlwm ntawm cov kabmob. Hom thiab tus nqi ntawm lubricant siv yuav txawv nyob ntawm daim ntawv thov.

Lwm yam uas yuav raug txiav txim siab thaum xaiv cov kabmob muaj xws li ib puag ncig, qhov kub thiab txias, kev vibration, suab nrov, thiab cov kev xav tau ntawm kev teeb tsa.

Hauv kev xaus, kev xaiv ntawm txoj cai bearing rau lub tsheb hnyav yog ib qho tseem ceeb los xyuas kom meej qhov ua tau zoo tshaj plaws, kev ua tau zoo, thiab kev nyab xeeb. Hom thiab specification ntawm cov kabmob yuav nyob ntawm daim ntawv thov, lub peev xwm thauj khoom, thiab lwm yam, thiab xaiv qhov zoo yog qhov kev txiav txim siab tseem ceeb.
