已经研究了铅含量变化于10~50%(按重量计)之间的一些铝轴承合金的减摩性和抗咬合性,研究是使用一台为研究而设计的轴承试验机在不同的润滑条件下进行的。在连续油润滑的情况下,所有加铅的合金的轴承都能在边界润滑和混合润滑工况的范围内运转而不咬合,而基体合金则在加铅合金在流体动力润滑工况下会发生咬合。轴承发生咬合的载荷主要决定于轴承的摩擦状态。通常,发现只有在铅浓度是在10~25%(按重量的范围计)内,向铅合金中加入铅才能降低界面摩擦和改善它们的抗咬合能力。含铅的铝合金也显示出吸收和储存润滑油的能力,因而可以用它来减小在供油失效的情况下的摩擦。
The antifriction and seizure resistance of some aluminum bearing alloys with varying lead levels between 10 and 50% by weight has been studied using a bearing test machine designed for the study under different lubrication conditions Under In the case of continuous oil lubrication, all leaded alloy bearings can operate in the boundary lubrication and mixed lubrication conditions without bite, while the base alloy in the lead-added alloy under hydrodynamic lubrication conditions Bite. Bits bearing the main load depends on the bearing friction state. In general, it has been found that adding lead to a lead alloy only reduces the interfacial friction and improves their anti-seizure properties only at lead concentrations in the range of 10-25% by weight. Lead-containing aluminum alloys also show the ability to absorb and store lubricating oil so it can be used to reduce friction in the event of fuel failure.
