金屬【石墨軸承】的特征與使用的注意事項(xiàng)
在設(shè)計(jì)用油脂或低黏性流體潤(rùn)滑的金屬石墨軸承時(shí)應(yīng)注意的事項(xiàng)：潤(rùn)滑從流體潤(rùn)滑轉(zhuǎn)為邊界潤(rùn)滑時(shí)，軸承性能變化很大。首先要有良好的潤(rùn)滑條件①油脂的供給量均勻且充分。②負(fù)荷低較有利。③盡力減低軸承的溫度，以免油脂的性能惡化。 ④用水和低黏性流體潤(rùn)滑時(shí)，軸承的形狀和工作間隙非常重要。其次金屬石墨材料 通常采用含百分之八石墨的青銅基或鉛青銅基材料。
Precautions when designing metal graphite bearings lubricated with grease or low-viscosity fluids: When the lubrication is changed from fluid lubrication to boundary lubrication, the bearing performance varies greatly. First, there must be good lubrication conditions. 1 The supply of grease is uniform and sufficient. 2 low load is more favorable. 3 Try to reduce the temperature of the bearing to avoid deterioration of grease performance. 4 When lubricating with water and low viscosity fluid, the shape of the bearing and the working clearance are very important. Secondly, the metallic graphite material usually uses a bronze-based or lead-bronze-based material containing eight percent graphite.
