Kodi ubwino woyika zinthu pasadakhale pa ma bearing ndi wotani? 

Kodi kuyika zimbalangondo patsogolo n'chiyani?

Kawirikawiri,mabearing ozunguliraali ndi chilolezo china chake mu mkhalidwe wogwirira ntchito. Komabe, kuti akwaniritse cholinga china chake, pamene bearing yakonzedwa, bearing imapeza katundu wina wamkati kudzera mu njira ina yosinthira, ndipo imagwiritsidwa ntchito mu mkhalidwe wochotsa woipa, ndipo njira yogwiritsira ntchito iyi imatchedwa preload.

 

Kodi ubwino woyika zinthu pasadakhale ndi wotani?maberiya?

Kwamabearing ozungulira, kuyika bwino zinthu pasadakhale kungakhale ndi ubwino wotsatira:

 

1. Konzani kulondola kwa kuzungulira. Pambuyo poti bearing yayikidwa kale, malo olowera mkati amachotsedwa, ndipo chinthu chilichonse chozungulira chimakhala ndi preload inayake, ndipo mpheteyo imathandizidwa kuchokera mbali zonse, zomwe zingathandize kulondola kwa kuzungulira, kuti shaft ikhale yoyenera mu axial ndi radial directions, ndikuwonjezera kulondola kwa kuzungulira kwa shaft, monga spindle bearing ya chida chamakina ndi chida choyezera.

 

2. Konzani kuuma. Kulumikizana pakati pa chinthu chogudubuza ndi msewu wa raceway kumakhala kosalala, ndipo chinthu chogudubuza chingawonedwe ngati kasupe. Ma bearing okhala ndi clearance amathandizidwa ndi ma spring ochepa okha omwe ali mbali ya mphamvu. Ma bearing omwe adayikidwa kale amathandizidwa ndi kasupe mbali zonse, ndipo pali kuchuluka kwa preload, ndipo chiwerengero cha ma roll omwe amatha kunyamula katunduyo ndi chochulukirapo kuposa pamene pali masewera, kotero kuuma kumatha kukonzedwa. Mu ma bearing a mpira, ubale pakati pa kusintha kwa contact ya mpira ndi njira ndi katundu si wolunjika, ndipo contact stiffness imawonjezeka ndi kuwonjezeka kwa preload.

 

3. Kukonza moyo wa bearing. Pambuyo poyika kale, chiwerengero cha zinthu zozungulira zodzaza chimawonjezeka, katundu pa chinthu chilichonse chozungulira chimachepa, ndipo katunduyo amatha kugawidwa pa chinthu chilichonse chozungulira mofanana, kotero moyo wa bearing ukhoza kusinthidwa.

 

4. Kuwongolera kunyowa kwa bearing ndikuchepetsa phokoso. Kuyika mafuta patsogolo kumakhazikitsa filimu yokhazikika pakati pa chinthu chozungulira ndi msewu wa raceway, kumawongolera kunyowa pakati pa chinthu chozungulira ndi msewu wa raceway, ndipo kumatha kusintha mawonekedwe a kapangidwe kothandizira ndikuchepetsa phokoso.

 

5. Kuwongolera magwiridwe antchito a mpira wolumikizana ndi angular. Mu ma bearing a mpira wolumikizana ndi angular ozungulira mwachangu, kuyika bwino zinthu kungalepheretse kuzungulira kwa mpira wachitsulo, kuletsa kapena kuchepetsa kutsetsereka kwa mpira wachitsulo, komanso kuwongolera kutsetsereka kwa mpira wachitsulo.

 

6. Kuletsa zizindikiro za kugwedezeka ndi kuwonongeka kwa kukangana. Chozungulira chakunja kwenikweni ndi mtundu wa chozungulira chakuya cha mpira, chomwe chimadziwika ndi pamwamba pa m'mimba mwake wakunja kwa mphete yake yakunja, yomwe imatha kufananizidwa ndi pamwamba pa chozungulira chozungulira cha mpando wonyamula kuti chigwire ntchito yolumikizana. Chozungulira chakunja chimagwiritsidwa ntchito makamaka kunyamula katundu wozungulira ndi wozungulira kutengera katundu wozungulira, ndipo nthawi zambiri sikoyenera kunyamula katundu wozungulira wokha. Chimagwiritsidwa ntchito popanga zida zamakina popanda kugwedezeka, kapena m'njira zomwe kukangana ndi kuwonongeka kuyenera kulamulidwa poyambira ndi kuyimitsa pafupipafupi.

 

7. Yang'anirani momwe zinthu zimatsetsereka komanso kuzungulira. Ma bearing akunja ozungulira omwe amaikidwa amapangidwanso kuti azidzigwirizanitsa okha, osavuta kuyika, komanso ali ndi kapangidwe kawiri ka chipangizo chotseka chomwe chingagwire ntchito m'malo ovuta. Mpando woperekera nthawi zambiri umakhala wopangidwa ndi kupangidwa. Ma bearing oikidwa ndi zinthu zolondola kwambiri zomwe zimaphatikiza ma bearing a mpira wozama wotsekedwa ndi mafuta ndi ma housings amitundu yosiyanasiyana. Cholumikizira cha bearing chikhoza kuyikidwa mwachindunji ku thupi lalikulu la makinawo ndi ma bolts angapo, ndipo n'zosavuta kuyika ndikugwiritsa ntchito, monga ntchito yodzigwirizanitsa yokha komanso kubwezeretsanso mafuta. Mwachitsanzo, imagwiritsidwa ntchito mu ma bearing a mpira wozungulira womwe umagwiritsidwa ntchito mu ma mota apamwamba komanso ma bearing a cylindrical roller pa injini za jet.

Lipirani kuwonongeka ndi kung'ambika panthawi yogwira ntchito. Kuwonjezeka kwa malo otseguka chifukwa cha kuwonongeka kwa bearing panthawi yogwira ntchito kungabwezeretsedwe poyika pasadakhale.
