If it is used for material transportation, such as in factory workshops, mines, or logistics warehouses, conveyor belts are the main choice. For the food industry with light loads and high hygiene requirements, PVC or PU conveyor belts can be selected. In heavy – load environments like mines, steel – cord conveyor belts are more suitable because they can withstand greater tensile forces.
When it comes to power transmission, transmission belts are crucial. V – belts are commonly used for general power transmission due to their simple structure and low cost. Timing belts, on the other hand, are suitable for equipment with high requirements for transmission accuracy, such as printing machinery and CNC machine tools, as they can ensure an accurate transmission ratio.
- Rubber belts: The advantages are good flexibility and wear – resistance, which can adapt to a variety of complex working environments and are widely used in various industrial scenarios. The disadvantage is that in high – temperature and high – humidity environments, aging may be accelerated, shortening the service life.
- PVC conveyor belts: They have good chemical corrosion resistance, a smooth surface for easy cleaning, and are often used in industries such as food and electronics. However, their strength is relatively low, and they are not suitable for heavy – load and high – speed operation occasions.
- PU transmission belts: They have excellent wear – resistance, as well as high oil – resistance and hydrolysis – resistance. However, their cost is relatively high, and they may harden in low – temperature environments, affecting the transmission performance.
- Nylon flat belts: They have good flexibility and high transmission efficiency, and can maintain stability at high – speed operation. However, their load – bearing capacity is relatively limited, and they are not suitable for heavy – load transmission.
First of all, ensure that the installation environment is clean to avoid debris entering the belt system, which may affect the operation. During installation, strictly follow the installation guide provided by the equipment manufacturer to ensure that the tension of the belt is appropriate. An overly tight belt will increase wear and energy consumption, while an overly loose belt may cause slipping, affecting the transmission effect. At the same time, pay attention to the alignment of the pulleys. If the pulleys are not aligned, the belt will be unevenly stressed, shortening the belt life.
Regularly check the wear condition of the belt. If severe local wear or cracks are found, replace it in a timely manner. Keep the belt and pulleys clean to avoid the accumulation of oil, dust, etc. For components that need lubrication, lubricate them according to the specified cycle and lubricant. In addition, control the temperature and humidity of the working environment to avoid exceeding the applicable range of the belt, which helps to extend the service life of the belt.
Slipping may be due to insufficient belt tension. You can increase the tension of the belt by adjusting the tensioning device. In addition, the presence of oil on the surface of the belt or pulley can also cause slipping. In this case, clean the surfaces of the belt and pulley. If the load suddenly increases and exceeds the transmission capacity of the belt, the load should be appropriately reduced. If the belt is severely worn and the friction decreases, a new belt needs to be replaced.
Abnormal noise may be caused by uneven belt tension. Re – adjust the tension to make the stress of each part uniform. An uneven pulley surface or the presence of foreign objects can also cause noise. Check and clean the pulley surface and repair the uneven parts. In addition, interference between the belt and other components can also generate noise. It is necessary to check and adjust the positions of the relevant components to ensure smooth belt operation.
