1.When there is severe roller eccentricity
There always occurs abnormal noise with periodic vibration when belt conveyor rollers runs, especially the return roller. The reason is that its length is bigger, weight is heavier and the noise is bigger .There are two main reasons of the noise:
1. the seamless steel tube wall thickness is not even which generates large centrifugal force;
2. the center of two bearing ends hole center and the outer circle center has big deviation which leads to large centrifugal force.
The coupling of high speed motor of driving device and reducer or coupling with brake wheel occurs the abnormal noise, along with the vibration same with motor rotation frequency. Please adjust the motor and gearbox position timely in order to avoid fracture of gearbox input shaft.
3.Bend pulley and abnormal noise of the driving drum
During operation, the noise of turnabout pulley and driving pulley is small, the bearing usually damages when there is noise, please replace the bearing timely.
