Kev sib raug zoo ntawm bearing vibration thiab suab nrov

Cov kabmob suab nrov yog ib qho teeb meem feem ntau ntsib hauv cov txheej txheem ntawm kev tsim lub cev muaj zog, kev sim thiab siv.Tsuas yog tham txog qhov teeb meem bearing yog ib txoj hauv kev tsis yooj yim heev.Qhov teeb meem yuav tsum tau txheeb xyuas thiab daws los ntawm qhov kev xav ntawm kev koom tes raws li txoj cai ntawm kev sib raug zoo.

Rolling bearing nws tus kheej feem ntau tsis tsim suab nrov.Dab tsi yog qhov "kev coj tus kheej lub suab nrov" yog qhov ua tau lub suab ua thaum cov qauv nyob ib puag ncig cov kabmob vibrates ncaj qha lossis tsis ncaj.Yog li ntawd, cov teeb meem suab nrov feem ntau yuav tsum tau txiav txim siab thiab daws teeb meem ntawm kev vibration teeb meem nrog rau tag nrho daim ntawv thov bearing.Kev vibration thiab suab nrov feem ntau nrog.

Rau ib khub ntawm cov khoom, lub hauv paus ua rau lub suab nrov tuaj yeem raug ntaus nqi rau kev vibration, yog li kev daws teeb meem rau lub suab nrov yuav tsum pib nrog txo kev co.

Cov kabmob vibration tuaj yeem raug ntaus nqi los ntawm cov yam ntxwv xws li kev hloov pauv ntawm tus lej ntawm cov khoom dov, kev sib raug zoo, kev puas tsuaj ib nrab thiab muaj kuab paug thaum thauj khoom.Qhov cuam tshuam ntawm cov xwm txheej no yuav tsum raug txo kom ntau li ntau tau los ntawm kev teeb tsa tsim nyog ntawm cov kabmob.Cov hauv qab no yog qee qhov kev paub dhau los hauv daim ntawv thov los qhia rau koj, raws li kev siv thiab siv hauv kev tsim cov kabmob.

Exciting quab yuam yam tshwm sim los ntawm kev hloov nyob rau hauv tus naj npawb ntawm loaded dov ntsiab

Thaum lub radial load ua rau ntawm cov kabmob, tus naj npawb ntawm cov kabmob dov bearing lub load yuav hloov me ntsis thaum lub sij hawm kev sib hloov, uas yuav ua rau cov bearings muaj ib tug me ntsis hloov nyob rau hauv cov kev taw qhia ntawm lub load.Qhov tshwm sim ntawm kev vibration tsis tuaj yeem zam tau, tab sis nws tuaj yeem dhau mus rau hauv Axial preload yog siv rau txhua lub ntsiab lus dov kom txo kev co (tsis muaj feem xyuam rau cylindrical roller bearings).

Qhov tseeb yam ntawm mating qhov chaw

Yog tias muaj kev cuam tshuam zoo ntawm lub nplhaib bearing thiab lub rooj zaum los yog ncej, lub nplhaib bearing yuav deformed raws li cov duab ntawm qhov txuas.Yog tias muaj qhov sib txawv ntawm qhov sib txawv ntawm ob, nws yuav ua rau muaj kev vibration thaum ua haujlwm.Yog li ntawd, cov phau ntawv xov xwm thiab lub rooj zaum yuav tsum tau machined raws li qhov yuav tsum tau ua kom haum rau cov qauv.

Local puas yam

Yog hais tias cov kabmob raug tuav tsis raug lossis raug teeb tsa tsis raug, nws yuav ua rau muaj kev puas tsuaj ib nrab rau kev sib tw thiab cov khoom dov.Thaum cov kabmob puas muaj kev sib cuag nrog lwm cov khoom, cov kabmob yuav ua rau muaj kev vibration tshwj xeeb.Los ntawm kev txheeb xyuas cov kev vibration zaus, nws tuaj yeem txiav txim siab seb cov kabmob twg puas raug puas, xws li lub nplhaib sab hauv, lub nplhaib sab nraud lossis cov khoom dov.

Pollution factor

Cov kabmob ua haujlwm nyob rau hauv cov kab mob tsis huv, thiab nws yooj yim rau impurities thiab cov khoom nkag mus.Thaum cov pa phem no tsoo los ntawm cov khoom dov, lawv yuav vibrate.Qhov kev vibration theem tshwm sim los ntawm cov khoom sib txawv hauv cov impurities, tus naj npawb thiab qhov loj ntawm cov khoom yuav txawv, thiab tsis muaj cov qauv ruaj khov hauv qhov zaus.Tab sis nws kuj tuaj yeem tsim cov suab nrov nrov.

Kev cuam tshuam ntawm bearings ntawm kev vibration yam ntxwv

Nyob rau hauv ntau daim ntawv thov, lub rigidity ntawm cov kabmob yog kwv yees li tib yam li lub rigidity ntawm ib puag ncig cov qauv.Yog li ntawd, qhov kev vibration ntawm tag nrho cov cuab yeej tuaj yeem raug txo los ntawm kev xaiv cov kabmob uas tsim nyog (xws li preload thiab clearance) thiab configuration.Txoj hauv kev los txo kev vibration yog:

● Txo cov excitation quab yuam uas ua rau kev co hauv daim ntawv thov

● Ua kom cov damping ntawm cov khoom uas ua rau kev co kom txo tau resonance

● Hloov qhov rigidity ntawm cov qauv los hloov qhov tseem ceeb zaus.

Los ntawm cov kev paub tiag tiag, nws pom tau tias kev daws teeb meem ntawm cov kabmob yog qhov kev sib txuas ntawm cov chaw tsim khoom thiab cov neeg siv khoom.Tom qab rov ua haujlwm-hauv thiab txhim kho, qhov teeb meem tuaj yeem daws tau zoo dua.Yog li ntawd, nyob rau hauv kev daws teeb meem ntawm cov kabmob system, peb Ntau tus neeg tawm tswv yim rau kev koom tes thiab kev sib raug zoo ntawm ob tog.
