Special rollers can be divided into buffer rollers, self-aligning rollers, and anti-off rollers. If it is supported by the roller, it can be divided into bracket type and hanging type. Below, for the analysis of the reasons for the failure of the conveyor roller and the elimination method:
1. In places with corrosive substances such as salt spray, the surface of the outer cylinder is severely corroded, and surface corrosion will accelerate the wear of the conveyor belt. In order to solve this problem, a 160mm anti-static reinforced nylon outer cylinder was developed to prevent a new road from rusting the outer cylinder.
2. The idler often works under dusty conditions. The idler sometimes runs in the slime water. The sides of the grooved idler of the outdoor conveyor will also seep into the gap along the shaft end due to rainwater, causing the bearing dust cover and its retention. Rust, grease deterioration. An effective measure to improve the sealing structure and improve the life of the roller.
3. The roller should use lithium-based grease, the dropping point is high, the grease is not easy to be lost, and it is not easy to deteriorate and agglomerate, which can extend the service life of the roller and reduce the friction resistance.
4. Bearing failure is mainly caused by moisture, dust or foreign matter intrusion, causing corrosion of the bearing and deterioration of the grease. Increase the diameter of the ball, use a single-sided open nylon cage, and increase the axial clearance of the roller bearing can effectively prevent a bearing jam. Its life is more than five times that of ordinary bearings, and power consumption can be reduced by about 18%.
