Maintain of conveyor pulley

The drive pulley can be further divided into two aspects: a drive pulley that requires external force for power output, a driven pulley that only performs power transmission, and a drive transmission roller that has an internal drive. The driven drive roller has exactly the same structure as the bend pulley, so the two roller products can be replaced with each other.

The drive pulley is the main transmission component of the belt conveyor. The drive pulley transmits the powerful torque of the main motor of the belt conveyor to the conveyor belt, and drags the load to realize transportation. Its reliability and service life seriously affect the performance of the conveyor. At present, most of the drive rollers are manufactured by welding methods, and the main structures are generally divided into a cylinder body, a cylinder hub, and a drum shaft. In the normal operation of the belt conveyor, the driving drum is subjected to the circumferential shearing force and the alternating radial tensile stress and compresive stress. The crack in the welding position is easily expanded, causing fatigue damage and causing the drum to fail. Therefore, the design of the welding roller welding position is particularly important.

Maintenance method of the driving pulley:
1. Regularly clean the foreign matter such as dust on the drive pulley;
2. For the welding of the drum shell and the end cover of the drive pulley, it is necessary to ensure regular inspection;
3, to maintain the good lubrication of the drive pulley, reduce the damage of the pulley;
4, to avoid overloading the drive pulley, this is a powerful maintenance of the pulley, which is a strong guarantee to extend its service life
