对浮动油封频繁漏油及损坏的原因进行了分析,并通过对返厂大修摇臂的拆解及测量对其进行了验证。结果表明:行星减速器中双列圆锥滚子轴承磨损严重,内部游隙严重超差是造成浮动油封频繁漏油及损坏的主要原因。
The reasons for the frequent oil leakage and damage of the floating oil seal were analyzed, and the disassembly and measurement of the overhaul rocker arm were verified. The results show that the double row tapered roller bearings in the planetary reducer wear seriously and the serious internal clearance is the main cause of the frequent oil leakage and damage of the floating oil seal.
