Kodi njira yopangira superfinishing ya bere ndi yotani?

Njira yopangira superfinishing siigwiritsidwa ntchito kokha m'makampani opanga ma bearing, komanso m'mainjini, ndipo makina ena olondola ndi zida zayambanso kugwiritsa ntchito njirayi.

Kodi kulondola kwambiri kwa bere ndi chiyani?

Kumaliza bwino kwa bearing ndi njira yosalala yomwe ndi kayendedwe ka chakudya kuti mupeze kupukusa pang'ono.

Pamwamba pake nthawi zambiri pamakhala pozungulira bwino musanamalize kupukuta. Makamaka, izi zikutanthauza njira yokonzera yosalala yomwe siikakamiza kwambiri ntchito yogwirira ntchito pogwiritsa ntchito chida chopukutira bwino (mwala wamafuta) pansi pa mafuta abwino komanso ozizira, ndipo imapanga kuyenda kwachangu komanso kwaufupi kobwerezabwereza pa ntchito yogwirira ntchito yozungulira pa liwiro linalake mozungulira mbali yowongoka yozungulira ntchito yozungulira.

Kodi ntchito ya superfinishing yonyamula katundu ndi yotani?

Mu njira yopangira ma bearing ozungulira, superfinishing ndi njira yomaliza yopangira mphete yonyamula katundu, yomwe imagwira ntchito yofunika kwambiri pochepetsa kapena kuchotsa kupotoka kozungulira komwe kumasiyidwa ndi kugaya, kukonza cholakwika cha mawonekedwe a ngalande, kukonza kukhwima kwake pamwamba, kukonza mawonekedwe ndi kapangidwe kake ka pamwamba, kuchepetsa kugwedezeka ndi phokoso la bearing, ndikukweza ntchito ya bearing.

Ikhoza kufotokozedwa m'mbali zitatu zotsatirazi

1. Zingathe kuchepetsa bwino kugwedezeka. Pomaliza ntchito, pofuna kuonetsetsa kuti mwala wamafuta nthawi zonse umagwira ntchito pamwamba pa mafunde ndipo sukhudza chimbudzi, mzere wa mwala wamafuta womwe umakhudzana ndi chimbudzi umakhudza kutalika kwa mafunde pamwamba pa chimbudzi, kotero kuti kuthamanga kwa chimbudzicho kukhale kwakukulu, ndipo nsonga yozungulira imachotsedwa, motero kuchepetsa kugwedezeka.

2. Konzani cholakwika cha groove cha msewu wothamanga wa mpira. Kumaliza bwino kwambiri kumatha kukonza cholakwika cha groove cha pafupifupi 30% ya misewu yothamanga.

3. Zingapangitse kuti pakhale kupsinjika pamwamba pa chinthu chopukutira bwino kwambiri. Pomaliza, kusintha kwa pulasitiki yozizira kumachitika makamaka, kotero kuti pambuyo pomaliza, kupsinjika kotsalira kumapangidwa pamwamba pa chinthu chopukutira.

4. Ikhoza kuwonjezera malo olumikizirana a pamwamba pa ntchito ya ferrule. Pambuyo pomaliza bwino, malo olumikizirana a pamwamba pa ntchito ya ferrule akhoza kuwonjezeka kuchoka pa 15% ~ 40% mutatha kupukuta mpaka 80% ~ 95%.

Kuchitira superfinishing ndondomeko:

1. Kudula mabearing

Pamene pamwamba pa mwala wopera pakhudzana ndi nsonga yozungulira ya malo otsetsereka a raceway, chifukwa cha malo ochepa olumikizirana ndi mphamvu yayikulu pa malo a unit, pansi pa mphamvu inayake, mwala wopera poyamba umagwiritsidwa ntchito "kudula kumbuyo" kwa chogwirira ntchito, kotero kuti gawo la tinthu tating'onoting'ono tomwe tili pamwamba pa mwala wopera limagwa ndikusweka, zomwe zimavumbula tinthu tating'onoting'ono tating'onoting'ono tomwe timadula. Nthawi yomweyo, kugundana kwa pamwamba pa chogwirira ntchito kumadulidwa mwachangu, ndipo gawo lofooka la crest ndi grinding degeneration pamwamba pa chogwirira ntchito limachotsedwa podula ndikudula kumbuyo. Gawoli limatchedwa gawo lodula, ndipo ndi gawoli pomwe gawo lalikulu lachitsulo limachotsedwa.

2. Kudula theka la mabearing

Pamene ntchito yokonza ikupitirira, pamwamba pa chogwirira ntchito chogwirira ntchito chimakonzedwa pang'onopang'ono. Panthawiyi, malo olumikizirana pakati pa mwala wopera ndi pamwamba pa chogwirira ntchito amawonjezeka, kuthamanga kwa gawo lililonse kumachepa, kuya kwa kudula kumachepa, ndipo mphamvu yodula imachepa. Nthawi yomweyo, ma pores pamwamba pa mwala wopera amatsekedwa, ndipo mwala wopera umakhala wochepa. Gawoli limadziwika kuti gawo lodulidwa theka la kumaliza bere, pomwe zizindikiro zodula pamwamba pa chogwirira ntchito chogwirira ntchito zimakhala zopepuka komanso zowala kwambiri.

3. Gawo lomaliza

Gawo ili lingagawidwe m'magawo awiri: gawo loyamba ndi gawo losinthira kugaya; lachiwiri ndi gawo lopera mutasiya kudula.

Gawo losinthira popera:

Njere zokwawa zimadzinola zokha, m'mphepete mwa njere zokwawa zimasalala, chip oxide imayamba kulowetsedwa m'malo opanda mwala wamafuta, ufa wokwawa umatseka ma pores a miyala yamafuta, kotero kuti njere zokwawa zimatha kudulidwa mofooka, limodzi ndi kutulutsa ndi kupukuta, kenako kukhwima kwa pamwamba pa ntchito kumachepa mwachangu, ndipo pamwamba pa mwala wamafuta pamamangiriridwa ndi black chip oxide.

Siyani gawo lopukutira:

Kukangana kwa miyala yamafuta ndi workpiece kwakhala kosalala kwambiri, malo olumikizirana akuwonjezeka kwambiri, kupanikizika kumatsika, tinthu tating'onoting'ono tatha kulowa mufilimu yamafuta ndikukhudzana ndi workpiece, pamene kupanikizika kwa filimu yamafuta pamwamba pa bere kumakhala kofanana ndi kupanikizika kwa miyala yamafuta, mwala wamafuta umayandama. Pakupanga filimu yamafuta, palibe chodulira chomwe chimachitika. Gawoli ndi lapadera pakumaliza kwambiri.
