Momwe Mungakulitsire Moyo wa Mabearings Anu a Slewing Ring

 

Kulephera msanga ndi vuto lofala la mabearing akuluakulu (monga 8″ mpaka 10′) m'magwiritsidwe ntchito olemera komwe kumasintha nthawi zambiri. Mu zida zazikulu zozungulira, monga ma cranes, ma excavator ndi makina obowola ngalande, achogwirira mphete choduliraayenera nthawi imodzi kuthana ndi zovuta zonyamula katundu zomwe zimaphatikizapo mitundu yosiyanasiyana ya kutsitsa, kuyika kwa radial ndi kuyika kwa tilting moment.

 

Mwamwayi, pali njira yosavuta yotetezera ndalama zomwe mwayika mu ma bearings opangidwa mwapadera. Imatchedwa kukonza nthawi zonse, ndipo imatha kuletsa 96% yachogwirira mphete choduliraKulephera. Kuti muwonjezere nthawi yogwiritsira ntchito mabearing, ingotsatirani malangizo anayi awa - mafuta a raceway ndi magiya, kuyang'ana mphamvu ya ma bolts, ndi kuyang'anira chisindikizo - ndipo khalani tcheru ndi zizindikiro zinayi zochenjeza za mavuto omwe angakhalepo pa mabearing.

Kupaka Mafuta Opangira Zimbalangondo

Bearing iyenera kudzozedwa mafuta nthawi ndi nthawi ndi mafuta olemera komanso opanikizika kwambiri. Ikani shoti yaulere pa zolumikizira zozungulira bearing pa nthawi yomwe ikulangizidwa mu buku la woyendetsa.

 

Mafuta nthawi zambiri amauma kwa nthawi yayitali, zomwe zimapangitsa kuti madzi aziundana mkati mwa chogwirira. Mutha kupewa izi mwa kuwonjezera mafuta osachepera miyezi isanu ndi umodzi iliyonse, ngakhale zida zitakhala kuti sizikugwira ntchito.

 

Mafuta Opaka Zida

Ma bearing ambiri akuluakulu ali ndi mano a giya omwe amafunikira mafuta, ndipo zofunikira zimenezo n'zosiyana ndi zomwe zili pa bearing yokha. Popeza ntchito ya mano yolumikiza mano imakonda kutulutsa mafuta, magiya ayenera kudzozedwa maola asanu ndi atatu aliwonse pazida zozungulira pang'onopang'ono kapena zozungulira nthawi ndi nthawi, komanso nthawi zambiri pazida zozungulira mwachangu kapena mosalekeza. Mafuta ochepa ayenera kulowetsedwa pamalo olumikizirana pakati pa giya ndi pinion.

 

Zisindikizo

Zisindikizo zomwe zili pa bearing ziyenera kuyang'aniridwa nthawi ndi nthawi kuti zitsimikizire kuti zili bwino. Anthu ambiri amanyalanyaza kufunika kwa zisindikizo, koma zimathandiza kwambiri kupewa kuipitsidwa ndi ma bearing raceway.

 

Maboluti

Kuyang'ana mphamvu ya ma bolts kuyenera kukhala gawo la njira iliyonse yosamalira nthawi zonse. Kuchuluka kwa ma bolts amenewa kumadalira kuopsa kwa ntchito. Kugwedezeka ndi kugwedezeka nthawi zambiri kumamasula ma bolts, koma kuyang'ana mphamvu ya ma bolts nthawi ndi nthawi komanso kulimbitsa kudzathandiza kusunga mulingo woyenera wa preload.

 

Mabotolo omangira ayenera kukokedwa bwino ndipo ayenera kufufuzidwa nthawi ndi nthawi kuti atsimikizire kuti akumangika bwino. Mabotolo omangika bwino akhoza kulephera, zomwe zingawononge zida, komanso chofunika kwambiri, kuvulaza antchito.

 

Kusewera kapena kutseguka kwa bearing nthawi zambiri kumatanthauza kuti msewu wothamanga wasweka.chogwiriraImapangidwa ndi malo otseguka kuti igwirizane ndi kusweka pang'ono kwa kapangidwe koyikira. Kuwonongeka kumatha kuwonjezera malo otseguka kwambiri. Mu makina okhala ndi boom, kusewera kwaulere komwe kumakulitsidwa kutalika kwa boom kumalola kuti igwedezeke kumbuyo ndi kumbuyo pamene ikunyamula katundu, kuchepetsa 'kuuma' kwa boom yotalikirapo. Yang'anani malo otseguka a bearing ndi chizindikiro choyimitsa chomwe chimayesa kuchuluka kwa kapangidwe kake kamene kamapendekeka pamene boom yakwezedwa.

 

Kupera, kuphulika, kapena phokoso lomveka kuchokera ku bearing nthawi zambiri kumatanthauza kuti pakhoza kukhala mafuta osakwanira komanso/kapena kuwonongeka kwambiri mu raceway, kapena mabolts omasuka. Monga taonera kale, kudzoza mafuta pa bearing ndi kutsuka mafuta ndi njira yabwino yowunikira tinthu tachitsulo.

 

Kuvala Mochepa Kumatanthauza Kuwononga Ndalama Zochepa

Mwa kuyang'anira zizindikiro za kuwonongeka kwa mabeya ndikuchita zinthu zodzitetezera nthawi zonse, mutha kuchepetsa kwambiri mwayi woti beya ingawonongeke msanga. Izi zimachepetsa ndalama chifukwa zimapangitsa kuti zida zizigwira ntchito bwino, kupewa kuwonongeka komwe kungayambitse nthawi yopuma komanso kukonza zinthu zodula.

 

Kukhala ndi moyo wautali wa ma bearing kumatanthauzanso kuti ma bearing sangasinthidwe kawirikawiri, zomwe zimapangitsa kuti ndalama ziwonjezeke kwambiri. Ndipo nthawi ikafika yoti musinthe, ganizirani zokonzanso ma bearing anu akale m'malo mogula atsopano. Ma bearing osamalidwa bwino nthawi zambiri amatha kukonzedwa pamtengo wotsika kuposa theka la mtengo wosintha watsopano, ngati atakonzedwa asanawonongeke.
