Vibration Reliability Evaluation of Main Fan Spindle Bearings

2019-7-22  During the operation of the main fan, the spindle bearings show the following three faults: (1) Abnormal vibration occurs in the bearing housing, and the vibration acceleration increases gradually with time, increasing until the bearings are damaged. This phase lasts approximately one month. (2) After the main fan is running for a period of time, abnormal noise occurs in the bearing housing.

Measuring Vibration: The Complete Guide Brüel Kjær

What Is Vibration? A body is said to vibrate when it describes an oscillating motion about a reference position. The number of times a complete motion cycle takes place during the period of a second is called the frequency and is measured in hertz (Hz). The motion can consist of a single component occurring at a single frequency, as with a ...
