[ Flat belt conveyor manufacturers] Abnormal noise of belt conveyor :
When the belt conveyor is running, its driving device, driving rollers, redirecting rollers, and supporting roller groups will emit abnormal noise when it is abnormal. According to the abnormal noise, the failure of the equipment can be judged.
1) Noise when the roller is heavily eccentric.
When the belt conveyor is in operation, abnormal noise often occurs in the rollers, and it is accompanied by periodic vibration. The main cause of the noise is the uneven thickness of the seamless steel pipe used to make the support rollers. The centrifugal force generated is large and the sound is emitted. The position of such support rollers can be adjusted during maintenance to reduce the noise.
2) Noise when the two axes of the coupling are not concentric.
Abnormal noise emitted at the coupling between the high-speed end of the drive motor and the reducer, or the coupling with the brake wheel, this noise is also accompanied by vibration with the same frequency as the motor.
When this kind of noise occurs, the position of the motor and reducer should be adjusted in time to avoid the break of the reducer input shaft.
3) Abnormal noise of redirecting rollers and driving rollers.
When the redirecting roller and the driving roller work normally, the noise is very small. When abnormal noise occurs, the bearing is usually damaged. The main reasons are too large or too small clearance, shaft shifting, oil leakage or poor oil quality, and the bearing end cap is not tightly sealed. Debris can cause bearing wear and temperature rise. At this time, the leakage point should be eliminated, the lubricant should be replaced, and the bearing should be replaced in the heavy case.
4) Reducer noise.
The cause of the vibration or sound abnormality of the reducer is that the ground screw is loose, the center of the wheel is not correct or the screws of the wheel are loose, the gear is out of gear or worn seriously, or the reducer is short of oil. You should repair or replace the parts in time.
5) Noise from the motor.
There are several reasons for the abnormal vibration and sound of the motor: excessive load; low voltage or two-phase operation; foundation bolts or loose wheels; bearing failure; short circuit between the turns of the motor.
Should stop inspection, reduce the load, check the loosening of the screws, check the bearing damage.
