When the belt conveyor is running, its driving device, driving roller, reversing roller and idler group will make abnormal noise when they are abnormal. The equipment fault can be judged according to the abnormal noise.

1. Noise when the idler is seriously eccentric

During the operation of the belt conveyor, abnormal noise often occurs to the idler, accompanied by periodic vibration, especially to the return idler. Because of its large length, self weight, and high noise, there are two main reasons for the noise. One is that the wall thickness of the seamless steel pipe used to manufacture the idler is uneven, and the centrifugal force generated is large. The other is that the deviation between the center of the bearing holes at both ends and the center of the outer circle is large during processing, If the centrifugal force is too large, the bearing can be used continuously without damage and noise.

2. Noise when two shafts of the coupling are not concentric

Abnormal noise from the coupling between the motor and the reducer at the high speed end of the drive device or the coupling with the brake wheel. This noise is also accompanied by vibration with the same rotating frequency as the motor. When this noise occurs, the position of the motor reducer should be adjusted in time to avoid the fracture of the input shaft of the reducer.

3. Abnormal noise of reversing drum and driving drum

The turning drum and drive drum make little noise during normal operation. In case of abnormal noise, the bearing is generally damaged and the bearing seat makes a gurgling noise. At this time, the bearing should be replaced.
