用于监测齿轮状态的技术
摘要：
一种用于对系统(2-2)执行下述行为的方法/设备，所述系统(2-2)包括由齿轮(2-16)紧随的电动马达(2-8)和速度输出单元(2-10)，所述行为是：当系统处于已知的良好操作状态时，监测在测量周期内来自系统的第一组频率；将监测到的第一组频率或其衍生物存储在长期存储系统中作为参考数据；当系统处于未知的操作状态时，监测在测量周期内来自系统的第二组频率；在频域中将监测到的第二组频率和监测到的第一组频率相比较；在所述频域中，检测从监测到的第二组频率和监测到的第一组频率得到的对应频率之间的变化。
摘要（英）：

Method/apparatus for performing following acts on a system (2-2) that comprises an electrical motor (2-8) followed by a gear (2-16), and a speed output unit (2-10): monitoring a first set of frequencies from the system over a measurement period when the system is in a known good operating condition; storing the first set of monitored frequencies or derivatives thereof as reference data in a long-term storage system; monitoring a second set of frequencies from the system over a measurement period when the system is in an unknown operating condition; comparing the second set of monitored frequencies with the first set of monitored frequencies in a frequency domain; in the frequency domain, detecting changes between corresponding frequencies resulting from the second set of monitored frequencies and the first set of monitored frequencies.
