Thaum txhim kho, tsis txhob ncaj qha rau cov kabmob kawg lub ntsej muag thiab tsis muaj kev ntxhov siab. Xovxwm thaiv, lub tes tsho lossis lwm yam khoom siv yuav tsum tau siv los ua kom cov kabmob bearing tsis sib xws. Tsis txhob nruab los ntawm dov lub cev. Yog hais tias lub mounting nto yog lubricated, nws yuav ua rau lub installation ntau du. Yog tias qhov kev cuam tshuam haum loj, cov kabmob yuav tsum tau ua kom sov rau 80 ~ 90 ℃ hauv cov roj ntxhia thiab nruab kom sai li sai tau, nruj me ntsis tswj cov roj kub tsis pub tshaj 100 ℃, txhawm rau tiv thaiv cov nyhuv tempering hardness txo thiab cuam tshuam rau loj rov qab. Thaum koj ntsib teeb meem hauv disassembly, nws raug nquahu kom koj siv lub cuab yeej disassembly rub tawm sab nraud thaum ua tib zoo nchuav cov roj kub ntawm lub nplhaib puab, cov cua sov yuav ua rau cov kabmob puab lub nplhaib nthuav dav, kom nws yooj yim dua kom poob.
Tsis yog tag nrho cov bearings yuav tsum tau qhov tsawg kawg nkaus ua hauj lwm clearance, koj yuav tsum xaiv qhov tsim nyog clearance raws li tej yam kev mob. Nyob rau hauv lub teb chaws tus qauv 4604-93, lub radial clearance ntawm dov bearings yog muab faib ua tsib pawg: pawg 2, pab pawg 0, pawg 3, pab pawg 4 thiab pawg 5. Cov clearance qhov tseem ceeb yog successively los ntawm me mus rau loj, thiab pawg 0 yog tus qauv. tshem tawm. Cov pab pawg radial clearance yog tsim rau cov kev ua haujlwm dav dav, cov pa kub thiab kev cuam tshuam zoo sib xws; Loj radial clearance yuav tsum tau xaiv rau bearings ua hauj lwm nyob rau hauv tshwj xeeb tej yam kev mob xws li kub kub, kev kub ceev, tsis muaj suab nrov thiab tsis muaj kev sib txhuam. me me radial clearance yuav tsum tau xaiv rau precision spindle thiab tshuab cuab tam spindle bearings; Kev ua haujlwm me me tuaj yeem khaws cia rau cov menyuam bearings. Tsis tas li ntawd, tsis muaj kev tshem tawm rau cov kabmob sib cais; Thaum kawg, kev ua haujlwm tshem tawm ntawm cov kabmob tom qab kev teeb tsa yuav tsum me dua qhov kev tshem tawm thawj zaug ua ntej kev teeb tsa, vim tias cov kabmob yuav tsum tau dais qee qhov kev sib hloov, nrog rau cov elastic deformation los ntawm cov kabmob haum thiab thauj khoom.
Nyob rau hauv kev pom ntawm qhov teeb meem sealing tsis xws luag ntawm bearings nrog inlaid sealing, muaj ob kauj ruam yuav tsum tau ua nruj me ntsis nyob rau hauv tus txheej txheem ntawm kev hloov.
1. Inlaid sealing bearing cover qauv hloov mus rau ob sab ntawm cov kabmob, thiab cov qauv kev teeb tsa ntawm cov kabmob yog hloov kho los ntawm cov khoom siv. Kev sib cuag ncaj qha nrog cov kabmob tsis tas yuav tsum tau, thiab cov kabmob muaj plua plav pov thawj los ntawm sab nraud ntawm cov kabmob. Cov nyhuv sealing ntawm cov qauv no yog siab dua li ntawm cov kabmob nws tus kheej muag los ntawm tus neeg sawv cev bearing, uas ncaj qha thaiv txoj kev ntxeem tau ntawm cov khoom granular thiab ua kom huv si ntawm cov kabmob sab hauv. Cov qauv no txhim kho lub tshav kub dissipation qhov chaw ntawm cov kabmob thiab ua rau muaj kev puas tsuaj me me rau kev ua haujlwm ntawm kev qaug zog ntawm cov kabmob.
2. Txawm hais tias cov txheej txheem sealing sab nraud ntawm cov kabmob muaj cov nyhuv sealing zoo, txoj kev tshav kub dissipation kuj raug thaiv, yog li cov khoom cua txias yuav tsum tau nruab. Cov cuab yeej ua kom txias tuaj yeem txo qis kev ua haujlwm kub ntawm cov roj nplua nyeem, thiab kev ua haujlwm kub ntawm cov kabmob tuaj yeem raug zam los ntawm cov cua sov ua kom sov tom qab txias.
