鋅基耐磨合金的特點(diǎn)
作為優(yōu)良的易損材料,,自身具有優(yōu)良的減磨,、耐磨性,、其對(duì)配磨件的磨損比銅合金小,。從而提高了機(jī)械傳動(dòng)零碎件的使用壽命,,保持了機(jī)械加工精度。延長(zhǎng)了機(jī)械維護(hù)周期,,提高了生產(chǎn)效率,,對(duì)潤(rùn)滑油的親和性好,且導(dǎo)熱率高于銅合金數(shù)倍,散熱快,,工作中保持較低的溫度,,抗咬合性能優(yōu)良。
鋅基耐磨合金的三大使用優(yōu)勢(shì)
比重小于銅合金,,花兩個(gè)的錢用三個(gè),。具有減磨性、耐磨性能好,、使用壽命高于銅合金,。散熱快、抗咬合性好,。
鋅基耐磨合金的運(yùn)用
這類軸承用于各種工程機(jī)械用來(lái)替代傳統(tǒng)的銅合金制造的軸套,、軸瓦、滑塊,、齒輪,、蝸輪等減磨材料。并在鍛壓機(jī)床,、水泵,、注塑機(jī)、軋鋼,、石油,、礦山、起重,、閥門等行業(yè)應(yīng)用,,均取得成功并得到充分肯定。
