What are the vibration and noise problems of roller conveyors during speed regulation?

Roller conveyor may encounter vibration and noise issues during speed adjustment, which not only affect the stable operation of the equipment but may also interfere with the work environment and surrounding equipment. Below is a detailed analysis of these two issues:

1. Vibration Issues
Causes:
When adjusting the speed, if the speed changes too quickly or is unstable, it may intensify the friction and collision between the rollers and the material, or between the rollers and the supports, leading to vibration.
If the installation foundation of the roller conveyor is unstable or the floor is uneven, vibration may occur during operation.
Significant wear on the conveyor’s transmission components (such as bearings, gears, etc.) or poor lubrication can also trigger vibrations.

Solutions:
Ensure smooth speed changes during adjustment to avoid sudden acceleration or deceleration.
Strengthen the installation foundation of the roller conveyor to ensure the equipment is stable and reliable.
Regularly inspect and maintain the transmission components, promptly replace worn parts, and maintain good lubrication.

2. Noise Issues
Causes:
During speed adjustment, the friction and collisions between the rollers and the material, or between the rollers and the supports, generate noise.
Wear and poor lubrication of transmission components (such as bearings, gears, etc.) can increase noise.
Abnormal operation of driving devices such as motors and reducers may also produce noise.

Solutions:
Select appropriate materials to reduce noise, such as using high-density polyethylene to make the rollers, which reduces the friction noise between the rollers and the material.
Keep the roller conveyor clean and well-lubricated to prevent noise caused by dirt buildup or lack of lubrication.
Regularly inspect and maintain the transmission components, replace severely worn parts, and maintain good lubrication.
For motors, reducers, and other driving devices, ensure they are operating normally to prevent abnormal noise. If necessary, noise isolation or vibration reduction measures can be adopted to minimize noise.
