Kodi n’chiyani chimayambitsa phokoso la bearing?

Phokoso mu bearing lingayambitsidwe ndi zinthu zingapo, koma pafupifupi zonse zimagwirizana ndi kugwedezeka.Lolani'kambirananimomwe ubwino, kuyenerera, ndi kusankha mafuta kungakhudzire kuchuluka kwa kugwedezeka ndi phokoso mu bearing.

 

Phokoso lochokera ku bearing nthawi zambiri limagwirizanitsidwa ndi ma wheel bearing owonongeka m'magalimoto. Ma wheel bearing akawonongeka, phokoso lochulukirapo mwina ndiyo njira yosavuta yodziwira kuti bearing yasweka. Koma, bwanji za ma bearing m'magwiritsidwe ena?

 

Mphete zoperekera mabearing ndi mipira sizili zozungulira bwino. Ngakhale zitaphwanyidwa bwino kwambiri, mipira ndi misewu yothamangira mabearing sizimakhala zosalala bwino. Zolakwika zimenezi zingayambitse kugwedezeka kosafunikira, zomwe zingawononge bearing nthawi yonse ya moyo wake.

 

Kawirikawiri, pamakhala zolakwika pamakina monga malo okhwima kapena osafanana zomwe zimapangitsa kuti mphete imodzi isunthe kapena kugwedezeka mozungulira poyerekeza ndi inayo. Kuchuluka ndi liwiro la kayendedwe kameneka zimathandiza kuti pakhale kugwedezeka kwa bearing ndi phokoso la bearing.

 

Mipira yoyipa kapena yoonongeka kapena njira zoyenderamo, kuzunguliridwa bwino kwa mpira kapena njira yoyenderamo, kuipitsidwa mkati mwa bearing, mafuta osakwanira, shaft kapena malo olowera osayenerera komanso kusewera kolakwika kwa radial zonse zingapangitse kuti bearing igwedezeke ndipo, zingayambitse phokoso lochulukirapo.

 

Pofunafuna bearing yokhala ndi phokoso lochepa, bearing yabwino idzakhala ndi mawonekedwe abwino kwambiri pa mipira ndi malo oimikapo magalimoto. Panthawi yopanga, kuzungulira kwa mipira ndi mphete zoikira zidzayang'aniridwa bwino kwambiri. Kusalala kapena bata la bearing kumatha kuwonedwa ndi ma accelerometer omwe amayesa kugwedezeka kwa bearing pa mphete yakunja, nthawi zambiri ndi mphete yamkati ikuzungulira pa 1800 rpm.

 

Njira ina yowongolera phokoso ndi kusankha radial play yomwe imalola bearing kugwira ntchito popanda radial play iliyonse ikagwiritsidwa ntchito. Ngati shaft kapena housing tolerances sizolondola, bearing ikhoza kukhala yolimba kwambiri, zomwe zingayambitse phokoso lochuluka. Mofananamo, shaft kapena housing rounding yosauka ingasokoneze mphete za bearing, zomwe zingakhudzenso kugwedezeka ndi phokoso la bearing.

 

Kuyika ma bearing fitting ndi chinthu china chofunikira kuganizira. Kuchita zinthu molakwika poyika ma bearing fitting kungayambitse mabala m'misewu ya ma bearing fitting zomwe zingawonjezere kugwedezeka kwambiri. Mofananamo, zinthu zodetsa zomwe zili m'ma bearing fittings zingayambitse kugwedezeka kosafunikira.

 

Kuti phokoso likhale lochepa, bearing iyenera kukhala yopanda zodetsa. Ngati bearing sigwiritsidwa ntchito pamalo oyera kwambiri, chitetezo ku dothi, monga zomatira zolumikizana, chiyenera kuganiziridwa.

 

Mu bearing yabwino, mafuta opaka phokoso lochepa amalimbikitsidwanso. Monga momwe dzinalo likusonyezera, mafuta osefedwa bwinowa amalola bearing kuyenda mwakachetechete chifukwa chosakhala ndi tinthu tating'onoting'ono tolimba. Tsopano pali zosankha zambiri zokhudzana ndi mafuta opaka phokoso lochepa, ndipo pali zosankha zingapo pamsika.
