Cov Lus Nug Feem Ntau (FAQ)
Q1: Qhov txawv ntawm tus qauv thiab Electric Motor Quality (EMQ) bearings yog dab tsi?
Cov kabmob EMQ raug kuaj xyuas kom nruj dua rau kev co thiab suab nrov dua li cov qib txheem. Thaum cov kabmob txheem tsom mus rau qhov muaj peev xwm thauj khoom, cov qauv EMQ tau tshwj xeeb kom txo qhov raceway waviness thiab dov qhov roughness ntawm qhov chaw, kom ntseeg tau tias kev ua haujlwm ntsiag to hauv kev siv lub cev muaj zog hauv tsev thiab kev kho mob.
Q2: Qhov kev tshem tawm sab hauv cuam tshuam li cas rau qib suab nrov ntawm cov kabmob sib sib zog nqus?
Qhov chaw sab hauv txiav txim siab qhov chaw ntawm cov khoom dov thiab cov raceways. Yog tias qhov chaw sib txawv nruj dhau, kev sib txhuam thiab cua sov ua rau muaj suab nrov. Yog tias xoob dhau, kev co tshwm sim. Kev xaiv qhov chaw sib txawv kom raug, xws li C3, tso cai rau kev nthuav dav thermal thaum tswj hwm lub kaum sab xis zoo tshaj plaws rau kev ntsiag to.
Q3: Cov bearings suab nrov qis rau cov motors puas siv tau rau hauv qhov chaw kub siab?
Yog, tab sis lawv xav tau cov hlau tshwj xeeb uas ruaj khov thaum tshav kub thiab cov roj ua los ntawm cov khoom siv kub siab. Cov roj uas tsis muaj suab nrov ib txwm yuav nyias nyias thaum kub siab, ua rau hlau sib chwv. Cov kev daws teeb meem tshwj xeeb uas muaj cov pob ceramic lossis cov txheej tshwj xeeb tuaj yeem tswj tau cov suab nrov qis txawm tias nyob rau hauv qhov kub heev.
Q4: Vim li cas cov bearings thiaj li nrov nrov tom qab kev teeb tsa hauv lub cev muaj zog tshiab?
Lub suab nrov tam sim ntawd feem ntau yog qhov tshwm sim ntawm "brinelling" (indents ntawm lub raceway los ntawm lub zog mounting tsis raug) lossis misalignment. Yog tias lub zog siv los ntawm cov ntsiab lus dov thaum lub sijhawm nias-fitting, qhov chaw raug puas tsuaj. Kev ua kom lub qhov thiab lub tsev kam rau siab yog qhov tseem ceeb rau kev tiv thaiv suab nrov.
Q5: Yuav tsum tau rov ua kom cov bearings uas raug tiv thaiv lossis kaw kom zoo li cas kom tsis txhob muaj suab nrov?
Feem ntau cov bearings uas muaj suab nrov tsawg yog "greased for life," txhais tau tias lawv tau kaw thiab tsis tas yuav rov ua kom lubrication dua. Kev sim ua kom lubrication ntawm cov bearings uas kaw lawm tuaj yeem ua rau muaj cov pa phem. Yog tias suab nrov nce ntxiv, nws feem ntau qhia tias cov roj nplua nyeem tau oxidized lossis txoj kev sib tw tau qaug zog, uas yuav tsum tau hloov cov bearings.
