铝40％锡的十字头轴承的试验 发展铝40％锡的目的是给予有最好的顺应性和抗粘咬性,合金的承载能力比白合金更大以避免作十字头轴承时产生疲劳。试验机试验(图30)示意了它的抗粘咬性仅稍低于白合金。硬度值暗示在发动机工作温度下它的顺应性也仅仅稍低于白合金。 由于这些原因,可以期望它的轴承特性是适合用于十字头轴承,而没有其他困难和不用表面涂层。
Testing of 40% Tin Crosshead Bearings Development of Aluminum 40% Tin is designed to give the best conformability and anti-stick bite, with an alloy that is more load-bearing than white metal to avoid fatigue when used as a crosshead bearing. The test machine test (Figure 30) showed that its anti-stick properties were only slightly lower than that of white metal. Hardness values suggest that its compliance at engine operating temperatures is only slightly lower than for white alloys. For these reasons, it can be expected that its bearing characteristics are suitable for use in cross-head bearings without any additional difficulties and without surface coating.
