行業技術資料分享:挖掘機軸承鋼的性能及要求

2017-11-16 16:56:55

挖掘機軸承對材料的基本要求在很大程度上取決于軸承的工作性能。選擇制造軸承的材料是否合適,對其使用性能和壽命將有很大影響。一般情況下,軸承的主要破壞形式是在交變應力作用下的疲勞剝落,以及由于摩擦磨損而使軸承精度喪失。此外,還有裂紋、壓痕、銹蝕等原因造成軸承的非正常破壞。因此,挖掘機軸承應具有高的抗塑性變形能力,少的摩擦磨損,良好的旋轉精度、良好的尺寸精度和穩定性,以及長的接觸疲勞壽命。而且其中很多性能是由材料和熱處理工藝所共同決定的。由于軸承對材料的基本要求是由軸承的破壞形式決定的,所以要求制造挖掘機軸承的材料經過后工序的一定熱處理后應具備下列性能:
