Fault detection of low speed planetary gearboxes

行星齿轮箱广泛应用于加拿大的油砂行业。它们也用于直升机，重型卡车和其他大型机械。行星齿轮箱的计划外停机具有重大的经济后果。在线评估行星齿轮箱的健康状况将为这些行业节省大量成本。该项目代表了阿尔伯塔大学和Syncrude研究中心之间的合作研究成果。其目的是开发用于检测行星齿轮箱关键部件中可能出现的早期故障的方法。将建立行星齿轮箱试验台。将对齿轮箱的牺牲部件进行机加工，以模拟现场操作中遇到的常见损坏模式。从测试台收集的数据和信号可以包括输出扭矩、旋转速度、轴承温度、声学信号和多轴振动信号。收集的数据将用统计方法和先进的信号处理技术进行分析。将建立模型来反映损坏状态与收集的数据和从数据中提取的某些参数之间的关系。从该项目中开发的结果将用于行星齿轮箱的在线基于状态的操作和维护，以防止意外故障。它们将使使用行星齿轮箱的公司受益，从而使加拿大经济受益。它们还将丰富世界齿轮箱知识库。将为加拿大工业培训高素质的人员。

Planetary gearboxes are widely used in Canada's oil sands industry. They are also used in helicopters, heavy-duty trucks, and other large-scale machinery. Unscheduled outages of planetary gearboxes have major economic consequences. On-line assessment of the health condition of planetary gearboxes will generate significant cost savings for these industries.This project represents a collaborative research effort between the University of Alberta and Syncrude Research Centre. Its objective is to develop methods for detection of early faults that may develop in key components of planetary gearboxes. A planetary gearbox test rig will be set up. Sacrificial components of the gearbox will be machined to mimic common damage modes experienced in field operations. Data and signals to be collected from the test rig may include output torque, rotational speed, bearing temperature, acoustic signals, and multi-axis vibration signals. The collected data will be analyzed with statistical methods and advanced signal processing techniques. Models will be constructed to reflect the relationship between the damage status and the collected data and certain parameters extracted from the data.The results to be developed from this project will be used in on-line condition based operation and maintenance of planetary gearboxes to prevent unexpected breakdowns. They will benefit companies using planetary gearboxes and as a result the Canadian economy. They will also enrich the world knowledge base on gearboxes. Highly qualified personnel will be trained for the Canadian industry.
