基于油液磨粒分析的变速箱磨损损伤评估

Wear Damage Assessment of Gearbox Based on Oil Particle Analysis

为了有效地评估变速箱的磨损状态,提出将铁谱分析技术与激光粒度分析技术综合应用于变速箱磨损磨粒的分析。首先运用分析式铁谱仪判断故障的磨损类型,并初步判断该磨损磨粒的粒径大小;然后根据激光粒度分析得到的粒径分布图判断该种故障的磨损程度。实例分析表明,该方法能较为准确地判定变速箱磨损初期的故障类型和磨损程度。

In order to effectively assess the wear state of the gearbox, ferrography and laser particle size analysis were applied to analyze the wear particle of gearbox.Ferrography was used to judge the types of wear faults firstly, and the size of wear particles was preliminarily judged.According to the distribution of particle size that was obtained by laser particle size analysis, the degree of wear was determined. The engineering application shows that the method can accurately judge the fault type and wear degree of the gearbox in the initial stage of wear.
