【摘要】：为研究某型运输机襟翼操纵机构滚动副的磨损行为,在常幅载荷下进行疲劳磨损试验。利用尺寸测量法测量不同循环次数下的磨损量,以滚动轴承磨损寿命计算公式计算滚动轴承理论寿命;根据疲劳磨损试验数据,计算可靠度R=0.99时的疲劳磨损可靠寿命的点估计,并与理论寿命进行比较。结果表明:在滚动轴承与滑轨组成的摩擦副中,滑轨磨损量较大,且存在明显磨合阶段;滚动轴承的磨损量较小,随时间基本呈线性关系,没有明显的磨合阶段。
[Abstract]:In order to study the wear behavior of the rolling pair of flap control mechanism of a certain type of transport aircraft, fatigue wear tests were carried out under constant amplitude load. The wear quantity of rolling bearing is measured by the method of dimension measurement, the theoretical life of rolling bearing is calculated by the formula of wear life of rolling bearing, the point estimation of reliable life of fatigue wear when reliability R = 0.99 is calculated according to the data of fatigue wear test. And compared with the theoretical life. The results show that, in the friction pair composed of rolling bearing and sliding rail, the wear amount of sliding rail is larger and there is obvious running-in stage, and the wear amount of rolling bearing is small, which is linear with time, and there is no obvious running-in stage.
