某型机分流头补偿器漏油故障分析

Fault Analysis of Oil Leakage in Distributor Head Compensator of a Certain Type of Aircraft

分流头补偿器协同前轮转弯控制系统,可实现飞机地面滑行、转弯、着陆时小角度航向修正及前轮减摆。文中针对分流头补偿器漏油故障进行分析,确定偏磨导致壳体和活塞损伤,加剧密封件磨损失效,是造成漏油故障的直接原因。通过工艺改进,有效降低了漏油故障的发生概率。

The distributor head compensator combined with the front wheel steering control system can realize the small angle course correction and front wheel Shimmy reduction when the aircraft taxiing,turning and landing on the ground.This paper analyzes the oil leakage fault and concludes that eccentric wear leads the shell and piston damage,accelerates seal wear failure,resulting in oil leakage directly.Process Improvement effectively reduces the occurrence of oil leakage failure.
