摘要研究了直升机主旋翼传动系统中行星齿轮和轴承故障的检测能力。这项工作支持了美国陆军航空应用技术局（AATD）和贝尔直升机德事隆的作战支持和维持（OSST）计划。OH-58 C行星系统的振动数据是在健康的变速箱以及各种种子故障部件上收集的。行星故障检测算法与收集的数据，以评估故障检测的有效性。行星齿轮齿裂纹和剥落是检测使用振动分离技术。太阳轮轮齿裂纹在振动分离过程中无法检测到。太阳轮齿剥落缺陷是可检测的。齿圈齿裂纹只能通过位于裂纹位置附近或裂纹正对面的加速度计清楚地检测到。包络法为行星轴承内外圈剥落故障的检测提供了一种有效的方法。
Abstract Studies were performed to demonstrate the capability to detect planetary gear and bearing faults in helicopter main-rotor transmissions. The work supported the Operations Support and Sustainment (OSST) program with the U.S. Army Aviation Applied Technology Directorate (AATD) and Bell Helicopter Textron. Vibration data from the OH-58C planetary system were collected on a healthy transmission as well as with various seeded-fault components. Planetary fault detection algorithms were used with the collected data to evaluate fault detection effectiveness. Planet gear tooth cracks and spalls were detectable using the vibration separation techniques. Sun gear tooth cracks were not discernibly detectable from the vibration separation process. Sun gear tooth spall defects were detectable. Ring gear tooth cracks were only clearly detectable by accelerometers located near the crack location or directly across from the crack. Enveloping provided an effective method for planet bearing inner- and outer-race spalling fault detection.
