Nā hiʻohiʻona kumu o Zinc{0}}Aluminum Alloy Bushings

Zinc -aluminium alloy bushings he mau mea hoohehee ia i haku nui ia me ka zinc (Zn) a me ka aluminika (Al), me na mea i hoohuiia e like me ke keleawe (Cu) a me ka magnesium (Mg). Hoʻohana nui ʻia lākou i nā ʻāpana pale -ʻaʻahu e like me nā bearings sliding a me nā pahu.

Hana Koʻikoʻi a me nā ʻano
Ka ikaika a me ka paakiki:
ʻO ZA27-2 (ma kahi o 27% aluminika, 2% keleawe) he 400–430 MPa ikaika a me ka paʻakikī Brinell o 100–120 HBS, hoʻohālikelike a ʻoi aku paha ma mua o kekahi mau keleawe alumini.

ʻAʻahu maikaʻi loa:
Haʻahaʻa friction coefficient (ʻano maʻamau ma kahi o 0.2–0.3, hiki ke hoʻemi ʻia i 0.06–0.12 me nā graphite inlays), ʻoi aku ka haʻahaʻa haʻahaʻa ma mua o ke keleawe keleawe, me ke ola lawelawe 3-5 mau manawa lōʻihi.

Māmā:
Ma kahi o 5.0 g/cm³ ka mānoanoa, 40%–45% ka māmā ma mua o ke keleawe keleawe, e kōkua ana e hōʻemi i ke kaumaha o nā lako.

Maikaʻi ka hoʻolei ʻana a me ka hana mīkini:
Ka helu heheʻe haʻahaʻa (ma kahi o 385 degere ), maikaʻi ka wai, kūpono no ka hoʻolei ʻana i nā ʻāpana paʻakikī paʻakikī -pā.
He maʻalahi ka ili i ka electroplate, spray, a anodize paha.

Hiki iā ʻoe iho-lubricating:
Hiki ke hoʻokō i ka mālama ʻana-ka hana manuahi ma o ka graphite inlays, kūpono no nā wahi ʻino me ka nele o ka aila, ka lepo, a i ʻole nā ​​kūlana lalo o ka wai.

ʻO ke kumu kūʻai:
ʻO ke kumu kūʻai waiwai ma kahi o 30% -40% o nā ʻāpana keleawe, a hiki ke hoʻemi ʻia ke kumukūʻai hana holoʻokoʻa ma mua o 50%.
