During the speed adjustment process, how to ensure the dynamic balance of the roller conveyor to reduce vibration and noise?

During the speed adjustment process, ensuring the dynamic balance of the roller conveyor is key to reducing vibration and noise. Below are some specific methods and measures:

1. Optimize the Transmission System
Select low-noise transmission components: Choose low-noise gears and chains, which significantly reduce noise during high-speed operation.
Ensure the stability of the transmission system: Transmission components should be securely installed to avoid looseness, which helps reduce vibration.
Regularly lubricate transmission components: Good lubrication reduces friction and wear, lowering both noise and vibration.

2. Adjust the Contact Between Rollers and Supports
Ensure concentricity between rollers and supports: Rollers and supports with high concentricity reduce friction and collisions, thereby lowering vibration and noise.
Adjust the gap between rollers and supports: A proper gap prevents excessive friction and collision between the roller and support during operation.

3. Perform Dynamic Balance Correction
Measure the vibration of the roller: Use specialized measuring equipment to measure the vibration amplitude (A) and phase angle (φ) of the roller at a speed of V.
Calculate and add balance mass: Using formulas derived from vibration theory, calculate the required balance mass and select an appropriate mass for correction. This helps reduce the imbalance forces when the roller rotates, thereby lowering vibration and noise.

4. Strengthen Equipment Installation and Maintenance
Ensure stable equipment installation foundation: The foundation should be level and sturdy to prevent vibration caused by uneven ground or an unstable foundation.
Regularly inspect and maintain equipment: Periodically check the wear of components such as rollers, bearings, and supports. Replace worn parts in a timely manner and maintain proper lubrication.

5. Use Soundproofing and Vibration-Damping Measures
Use soundproof materials at critical points: Materials like rubber pads and foam plastics can effectively isolate and reduce the propagation of noise.
Install vibration-damping devices: Devices like rubber vibration-damping pads and spring dampers can absorb and dissipate vibrational energy, reducing the impact of vibration on both the equipment and workers.

6. Optimize Speed Adjustment Strategy
Smooth speed adjustment: Ensure smooth speed changes during the adjustment process to avoid vibration and noise caused by sudden acceleration or deceleration.
Select the appropriate speed adjustment method: Choose the right speed adjustment method based on actual needs, such as using variable frequency drives or electromagnetic speed control for precise speed control.

By optimizing the transmission system, adjusting the contact between rollers and supports, performing dynamic balance correction, strengthening equipment installation and maintenance, employing soundproofing and vibration-damping measures, and optimizing the speed adjustment strategy, the dynamic balance of the roller conveyor during the speed adjustment process can be ensured. These measures will help reduce vibration and noise, improving the operational stability of the roller conveyor and the quality of the working environment.
