Chero ani anowanzo shandisa mabhero achaziva kuti kune marudzi maviri ekuzora mabheri: mafuta ekuzora uye girizi. Mafuta ekuzora uye girizi anoita basa rakakosha mukushandiswa kwemabheya. Vamwe vashandisi vangashamisika, ko mafuta uye girizi zvinogona kushandiswa kuzora mabheji nekusingaperi? Mafuta anofanira kuchinjwa rini? Mafuta akawanda anofanira kuwedzerwa sei? Nyaya idzi inyaya yakaoma mukutakura tekinoroji yekuchengetedza.
Chinhu chimwe chechokwadi ndechekuti mafuta ekuzora uye girisi hazvigone kushandiswa zvachose, nekuti zvakanyanya kushandisa mafuta ekuzora zvinokuvadza zvakanyanya kubereka. Ngatitarisei mapoinzi matatu ekutarisisa mukushandiswa kwemafuta ekuzora uye girisi yekutakura:
1.Lubricating mafuta uye girisi zvine adhesion yakanaka, kupfeka kuramba, tembiricha kuramba, ngura kuramba uye lubricity kune mabearings, anogona kuvandudza tembiricha oxidation kuramba, kunonoka kuchembera, kunyungudutsa carbon accumulation, uye kudzivirira simbi marara uye mafuta Chigadzirwa, kunatsiridza mechanical kupfeka kuramba, pressure resistance uye corrosion resistance.
2. Iyo yakawanda yekuzora girisi yakazadzwa, iyo yakakura friction torque inova. Pasi pehuwandu hwakafanana hwekuzadza, friction torque yemabhengi akavharidzirwa yakakura kupfuura iyo yemabhengi akavhurika. Kana iyo girizi yekuzadza iri 60% yenzvimbo yemukati vhoriyamu yekutakura, iyo torque yekukwenya haiwedzere zvakanyanya. Mazhinji emafuta ekuzora mumabhengi akavhurika anogona kusvinwa kunze, uye girizi yekuzora mumabhengi akavharidzirwa inodonha nekuda kwekukwesha torque kudziyisa.
3. Nekuwedzera kwehuwandu hwekuzadza kwemafuta ekuzora, kutonhora kwekukwira kwekutakura kunokwira mutsara, uye kutonhora kunokwira kwechisimbiso chakavharwa chakakwirira kudarika chebheji yakazaruka. Huwandu hwekuzadza kwegirisi yekuzora kune yakavharwa rolling mabhengi haifanire kudarika 50% yenzvimbo yemukati.
Iyo lubrication purogiramu yemabheri inobva pane nguva. Vatengesi vezvishandiso vanogadzira marongero ekuzora zvichienderana nemaawa ekushanda. Pamusoro pezvo, mutengesi wemidziyo anotungamira huwandu hwemafuta anowedzerwa panguva yekuronga kugadzirisa. Zvakajairika kuti vashandisi vemidziyo vachinje mafuta ekuzora munguva pfupi, uye kudzivirira kuwedzera mafuta ekuzora akawandisa.
