Qhov sib sib zog nqus groove pob bearings yog hom dov bearings uas nrov tshaj plaws, feem ntau tsim los tswj cov radial loads. Txawm li cas los xij, lawv muaj peev xwm ua tau ob qho tib si radial thiab axial loads zoo. Thaum tsuas yog rau radial loads, lub kaum sab xis ntawm kev sib cuag tseem nyob ntawm xoom. Interestingly, yog hais tias qhov sib sib zog nqus groove npas bearing muaj ib tug considerably loj radial clearance, nws muaj cov yam ntxwv zoo sib xws rau ib tug angular hu bearing thiab muaj peev xwm tiv taus ntau yam axial loads. Ib qho tseem ceeb kom zoo dua ntawm qhov sib sib zog nqus groove pob bearings yog lawv cov kev sib txhuam me me, uas ua rau lawv muaj peev xwm ua tiav qhov kev txwv siab.
Feem ntau siv hom dov bearings yog qhov sib sib zog nqus groove pob bearings, uas feem ntau muaj lub nplhaib puab, ib lub nplhaib sab nraud, txheej steel pob, thiab tawb. Cov kabmob no tuaj yeem muab faib ua ob pawg: ob kab thiab ib kab. Tsis tas li ntawd, lawv muaj nyob rau hauv ob qho kev tsim, qhib thiab kaw. Nyob rau hauv cov nqe lus ntawm qhib tsim, tsis muaj sealing qauv. Raws li qhov sib sib zog nqus groove pob bearings, muaj ob hom, nrog rau cov roj pov thawj thiab plua plav pov thawj. Plua plav seals feem ntau yog tsim los ntawm cov hlau phaj uas tiv thaiv cov kabmob txoj kev sib tw los ntawm cov plua plav. Hloov pauv, hom roj pov thawj yog cov roj sib txuas uas tiv thaiv cov roj lubricating hauv cov kabmob los ntawm kev ntws tawm.
txoj cai ua haujlwm
Lub luag haujlwm tseem ceeb uas qhov sib sib zog nqus groove pob bearings undergo yog radial, tab sis lawv muaj peev xwm ua tau ob qho tib si radial thiab axial loads. Yog hais tias tus kabmob tsuas yog dhau radial loads, ces lub kaum sab xis ntawm kev sib cuag yog xoom. Txawm li cas los xij, nrog rau qhov loj dua radial clearance, qhov sib sib zog nqus groove pob bearing tuaj yeem ua haujlwm zoo li cov kabmob sib tiv tauj thiab tuav tawm tsam qhov tseem ceeb axial loads. Tsis tsuas yog qhov sib sib zog nqus groove pob bearing muaj qhov sib txhuam coefficient tsawg, tab sis nws kuj muaj qhov txwv ceev. Kev hloov me ntsis ntawm cov ntsiab lus tseem ceeb qhia tau tias cov ntaub ntawv no tuaj yeem xa mus rau ntau txoj hauv kev thaum khaws cov lus tseem ceeb.
Kev tsim kho kabmob
Qhov sib sib zog nqus groove pob bearing yog ib qho zoo kawg nkaus ntau yam thiab dav siv hom kabmob vim nws cov qauv yooj yim thiab siab raug precision, uas ua rau nws yooj yim rau huab hwm coj-tsim ntawm tus nqi qis. Qhov tseeb, nws muaj ntau yam uas muaj ntau yam hloov kho muaj, txhua tus muaj lawv tus kheej cov txiaj ntsig thiab cov yam ntxwv.
Qee qhov kev hloov kho nrov ntawm cov kab sib sib zog nqus pob bearings suav nrog cov plua plav npog, roj hmab ntsaws ruaj ruaj, snap grooves, lub peev xwm loj ntawm lub pob, thiab ob chav kab teeb tsa. Cov kev hloov kho no tso cai rau qhov sib sib zog nqus groove pob bearing kom haum rau ntau qhov xwm txheej thiab ib puag ncig, ua rau nws muaj txiaj ntsig zoo dua li kev xaiv mus rau kev coj tus kheej rau ntau qhov kev lag luam thiab kev siv.
Zuag qhia tag nrho, qhov sib sib zog nqus groove pob bearing yog ib qho kev xaiv txhim khu kev qha thiab pheej yig uas yooj yim los tsim thiab kho, ua rau nws yog ib qho tseem ceeb ntawm ntau lub tshuab tshuab.
