Key Sub-assemblies of Conveyors

1. Belt

The belt is the most critical component of a conveyor system. It is responsible for transporting materials from
one point to another. Proper maintenance and inspection of the belt is crucial for ensuring the efficiency and longevity of the conveyor system.

2. Rollers and Idlers

Rollers and idlers are responsible for supporting the weight of the conveyor belt and materials. They should be inspected regularly for wear and tear and replaced if necessary.

3. Bearings

Bearings are responsible for supporting the load of the conveyor system. They should be lubricated regularly to prevent wear and tear and ensure smooth operation of the system.

4. Gear Reducers

Gear reducers are responsible for reducing the speed of the conveyor motor and increasing torque. They should be inspected regularly for wear and tear and replaced if necessary.

5. Electrical Components

Electrical components, such as motors and sensors, are responsible for the operation of the conveyor system. They should be inspected regularly for proper functioning and replaced if necessary.

Top 10 Most Common Conveyor Problems

1. Belt Tracking Problems

Belt tracking problems occur when the conveyor belt starts to veer off-center, causing it to rub against other components and eventually wear down. This can be caused by a misaligned belt, incorrect tension, or worn components.

2. Belt Tension Issues

Belt tension issues can cause the belt to slip or loosen, which can result in reduced performance and increased wear and tear. This can be caused by incorrect belt tensioning or worn components.

3. Chain Wear

Chain wear occurs when the chains that drive the conveyor system become worn down, causing the system to lose efficiency and eventually fail. This can be caused by lack of lubrication, incorrect tension, or worn components.

4. Motor Overheating

Motor overheating can occur when the motor that drives the conveyor system becomes too hot, causing it to fail. This can be caused by overloading, lack of ventilation, or worn components.

5. Bearing Problems

Bearing problems occur when the bearings that support the conveyor system become worn down, causing the system to lose efficiency and eventually fail. This can be caused by lack of lubrication, incorrect tension, or worn components.

6. Gear Reducer Issues

Gear reducer issues can occur when the gear reducers that reduce the speed of the conveyor motor and increase torque become worn down, causing the system to lose efficiency and eventually fail. This can be caused by lack of lubrication, incorrect tension, or worn components.

7. Sensor Problems

Sensor problems occur when the sensors that control the operation of the conveyor system become faulty, causing the system to malfunction. This can be caused by wiring issues, incorrect calibration, or worn components.

8. Control System Issues

Control system issues can occur when the control system that manages the operation of the conveyor system becomes faulty, causing the system to malfunction. This can be caused by wiring issues, incorrect calibration, or worn components.

9. Material Handling Issues

Material handling issues occur when the materials being transported by the conveyor system become stuck, causing the system to lose efficiency and eventually fail.
This can be caused by incorrect loading, worn components, or inadequate lubrication.

10. Noise Problems

Noise problems occur when the conveyor system becomes excessively noisy, causing disruptions and discomfort for workers. This can be caused by worn components, inadequate lubrication, or incorrect tensioning.

Pre-Troubleshooting Steps

Before troubleshooting your conveyor system, there are several steps you can take to prepare and ensure your safety.

Conducting an Initial Assessment

Conducting an initial assessment can help you identify potential problems and hazards before starting troubleshooting.
