Kawm txog cov qauv radial clearance rau cov bearings dov

Kev TuavQhov kev tshem tawm yog hais txog qhov ntau ntawm kev txav mus los thaum cov kabmob tsis tau teeb tsa rau hauv lub ncej lossis lub thawv kabmob, ib sab ntawm lub nplhaib sab hauv lossis lub nplhaib sab nraud yog kho, thiab tom qab ntawd sab uas tsis kho txav mus los radial lossis axially. Raws li kev taw qhia ntawm kev txav mus los, nws tuaj yeem faib ua radial clearance thiab axial clearance. Qhov kev tshem tawm kuj tseem ceeb heev rau kev siv cov kabmob.

Qhov radial clearance ntawm ib lub dov bearing yog qhov nruab nrab ntawm qhov radial nrug ntawm lub nplhaib sab nraud piv rau lub nplhaib sab hauv los ntawm ib qho radial eccentric txwv txoj hauj lwm mus rau qhov txwv txoj hauj lwm rov qab hauv lub xeev tsis-preloaded. Raws li lub teb chaws tus qauv GB / T307.1-2018, radial clearance yog muab faib ua tsib qib: loj, nruab nrab, me, me heev thiab me me ntxiv. Cov nqi clearance ntawm txhua qib yog raws li nram no: C2, CN, C3, C4, C5; C0, C1, C2, CN; Me rau C0, C1, C2, CN; Qhov tsawg kawg nkaus yog C0 thiab C1; Cov me me ntxiv yog C0 thiab C1, qhov twg C0 sawv cev rau qhov me me thiab C5 sawv cev rau qhov loj clearance.

 

Tsis tas li ntawd xwb, tus qauv ISO thiab tus qauv American ABMA kuj muaj qib sib txawv rau kev tshem tawm radial. Tus qauv ISO muab faib ua plaub qib: N, P, M, thiab K, thiab tus qauv American ABMA muab faib ua tsib qib: C1, C2, C3, C4, thiab C5. Thaum xaiv cov bearings, nws yog ib qho tsim nyog los qhia cov qauv siv los txiav txim siab chav kawm tshem tawm.

 

Qhov radial clearance ntawm ib tug bearings ncaj qha cuam tshuam rau nws lub neej kev pab cuam, kub nce, suab nrov thiab kev co thiab lwm yam khoom. Qhov clearance ntau dhau yuav ua rau lub neej luv dua ntawm bearing, txo qhov tseeb ntawm kev sib hloov, kev co thiab suab nrov; Yog tias qhov clearance me dhau, nws yooj yim ua rau muaj kev sib txhuam thiab cua sov nce, kub nce, thiab txawm tias ua rau bearing xauv. Yog li ntawd, thaum xaiv qhov clearance ntawm bearing, nws yog ib qho tsim nyog los xav txog qhov nruj ntawm bearing thiab qhov haum ntawm tus ncej, qhov sib txawv ntawm qhov kub los ntawm kev ua haujlwm ntawm bearing, thiab qhov sib txawv ntawm qhov coefficient nthuav dav ntawm bearing thiab tus ncej.
