The frequency of early failure of the bearing is generally 25 ~ 60kHz, belonging to the range of 20 ~ 100kHz ultrasonic frequency, the frequency of failures in the late often than 5kHz. 而振动探头的响应范围一般在10kHz以下，也就是说振动监测只能发现中后期的轴承故障，这时轴承已经进入较明显的磨损阶段，最早期的故障如润滑不良、很轻微的磨损等是很难监测到的，而超声波检测符合要求。 The vibration of
