Lub npe hu ua bearing clearance yog hais txog tus nqi ntawm kev txav mus los thaum cov kabmob kho ib sab ntawm nws lub nplhaib sab hauv lossis lub nplhaib sab nraud thaum nws tsis tau nruab rau hauv lub tog raj kheej lossis cov kabmob vaj tse, thiab tom qab ntawd sab tsis ruaj khov txav radially lossis axially. Raws li kev txav mus los, nws tuaj yeem muab faib ua radial clearance thiab axial clearance. Clearance kuj tseem ceeb heev rau kev siv cov bearings, yog li Tuam Tshoj bearing network qhia rau koj tias koj yuav tsum tsis txhob quav ntsej qhov no.
Rau kev ceev faj rau kev tshem tawm cov kabmob:
1. Qhov luaj li cas ntawm kev khiav hauj lwm clearance (hu ua hauj lwm clearance) muaj feem xyuam rau lub dov qaug zog lub neej, kub nce, suab nrov, kev co thiab lwm yam khoom ntawm cov kabmob.
2. Thaum ntsuas qhov bearing clearance, thiaj li yuav tau txais ib tug ruaj khov ntsuas tus nqi, qhov teev ntsuas load feem ntau yog siv rau cov kabmob. Yog li ntawd, tus nqi ntsuas yog loj dua qhov tseeb clearance (hu ua theoretical clearance), uas yog, nws tsub kom lub elastic deformation tshwm sim los ntawm kev ntsuas load. Rau cov menyuam bearings, elastic deformation yog me me thiab tuaj yeem tsis quav ntsej.
3. Qhov kev tshem tawm sab hauv ntawm cov kabmob ua ntej kev teeb tsa feem ntau qhia los ntawm kev tshem tawm theoretical.
4. Qhov kev tshem tawm tom qab txiav tawm qhov kev nthuav dav lossis kev cog lus ntawm ferrule los ntawm kev cuam tshuam haum thaum cov kabmob raug ntsia rau ntawm ncej lossis hauv vaj tse los ntawm kev tshem tawm theoretical hu ua "installation clearance". Qhov kev tshem tawm tom qab ntxiv lossis rho tawm qhov hloov pauv loj los ntawm qhov sib txawv ntawm qhov kub thiab txias hauv cov kabmob ntawm lub installation clearance yog hu ua "zoo clearance".
5. Cov kabmob tau nruab nrog qhov kev tshem tawm thaum nws muab tso rau hauv ib qho kev thauj khoom, uas yog, kev tshem tawm zoo ntxiv rau cov elastic deformation los ntawm cov kabmob load hu ua "ua haujlwm clearance".
6. Thaum kev ua haujlwm tshem tawm me ntsis tsis zoo, lub neej qaug zog ntawm cov kabmob ntev, tab sis lub neej qaug zog txo qis nrog qhov nce ntawm qhov tsis zoo clearance. Yog li ntawd, thaum xaiv lub bearing clearance, nws yog feem ntau tsim nyog los ua kom lub chaw ua hauj lwm clearance zero los yog me ntsis zoo. Tsis tas li ntawd, thaum lub rigidity ntawm bearing yuav tsum tau kho kom zoo dua los yog lub suab nrov yuav tsum tau txo, kev ua hauj lwm clearance yuav tsum tau muab ntxiv raws li ib tug tsis zoo nqi, thaum lub bearing kub nce sharply, kev ua hauj lwm clearance yuav tsum tau muab ntxiv raws li ib tug tshwm sim. tus nqi zoo, thiab lwm yam kev tsom xam tshwj xeeb yuav tsum tau ua raws li cov kev pabcuam.
