Acoustic detection of bearing anomalies present in two ways. One is the detection method based on acoustic noise, and the other is based on the vibration detection. (A), noise detection method: the noise is less than 20db silencer based environment, the use of high-quality microphones to extract a certain distance and direction of the sound pressure bearing signal, and by a certain method to extract the abnormal sound component abnormal sound is a direct measurement method.

Data show that the wear and tear caused by mechanical failure or the main reason for the early, more than half of all management and lubrication technology. Improve lubrication management, and prevention of bearings, gears and other moving parts friction abrasions or sintering, to prevent and reduce wear, friction reduction, accident prevention equipment, improve equipment efficiency; saving energy, improving energy utilization efficiency,

1: ntn bearing inner ring fixed:First, ntn lock nut bearings, ntn bearing inner ring and the locking nut from the shaft shoulder to achieve axial fixation. And have washers with anti-loose, safe and reliable, suitable for high-speed, heavy load situations. Second, ntn bearing a fixed withdrawal sleeves, withdrawal sleeves and adapter clamping sets the same way. However, because of withdrawal sleeves special nut, ntn bearing loading and unloading easy,
