摘要
火箭炮大推力机电伺服作动器是以高精度行星滚柱丝杠为核心部件的直线传动机构。为研究行星滚柱丝杠副疲劳稳定特性,开展了行星滚柱丝杠无故障与有故障疲劳对比试验;通过试验数据曲线,分析了行星滚柱丝杠副轮齿缺损和有无润滑脂两种工况对丝杠副负载、位移、转速、温升的影响。研究结果表明,在部分轮齿缺损或无润滑脂两种工况下,行星滚柱丝杠副依然可以保持较为稳定的负载、位移、转速、温升曲线;火箭炮大推力机电伺服作动器行星滚柱丝杠副在轮齿受损或少润滑脂情况下可免维护或少维护使用。
The high thrust electro-mechanical servo actuator in rocket launcher is a linear transmission mechanism with high precision planetary roller screw as its core component.In order to study the fatigue stability characteristics of planetary roller screw mechanism,a fatigue comparison test of fault-free and fault is carried out.Based on the test data curve,the influence of loss of gear tooth and two working conditions with or without grease on load,displacement,speed and temperature rise of planetary roller screw mechanism are analyzed.The result shows that planetary roller screw mechanism could maintain relatively stable load,displacement,speed and temperature rise curves under two working conditions of partial tooth defect or without grease.The planetary roller screw mechanism of high thrust electro-mechanical servo actuator could be used without maintenance or less maintenance for the engineering application in case of tooth damage and little grease.
