Mabeya ozungulira a singano a PNA12/28, okhala ndi mphete yamkati
Maberiyani ozungulira singano okhala ndi mphete yakunja yokhala ndi malo ozungulira akunja. Mphete ziwiri zokhala ndi polima zokhala ndi malo ozungulira amkati zimayikidwa mu chikwama chachitsulo chokokedwa ndikuyikidwa pamwamba pa mphete yakunja. Kapangidwe kameneka kamalola beriyani kuti igwirizane ndi kusakhazikika kwa shaft poyerekeza ndi nyumbayo. Mu ntchito zomwe shaft singalimbitsidwe ndikuphwanyidwa, maberiyani okhala ndi mphete yamkati ayenera kugwiritsidwa ntchito. Kusuntha kovomerezeka kwa axial kwa shaft poyerekeza ndi nyumbayo ndi kochepa pa maberiyani okhala ndi mphete yamkati. Ngati kusuntha kovomerezeka kwa axial komwe kumaperekedwa ndi mphete yamkati yokhazikika sikukwanira, ndizotheka kugwiritsa ntchito mphete yamkati yotambasulidwa.
Maberiya opanda mphete yamkati ndi chisankho chabwino kwambiri chokonzekera maberiya ang'onoang'ono, ngati shaft ikhoza kulimba ndikuphwanyidwa.
Makhalidwe a PNA12/28 Alignment needle roller bearingers
Kugwirizana ndi kusakhazikika kwa malo: Ma bearing a singano zozungulira amadzilungamitsa okha mpaka 3° ya kusakhazikika kwa malo.
Gawo lotsika: Mu ntchito zomwe malo ochepa amapezeka, mabearing a singano zozungulira amapereka yankho laling'ono.
Kunyamula katundu wambiri: Chifukwa cha kuchuluka kwa ma rollers, ma bearings a needle roller ali ndi mphamvu zambiri zonyamula katundu.
