How it worksThrough the friction between the conveyor belt and the roller, the roller drives the roller tube body, bearing seat, bearing outer ring and sealing ring to rotate, and realizes the transmission of logistics with the conveyor belt and together with it.
Influencing factors
1. Radial runout of the roller (this index directly affects the stability of material transportation)
2. Axial string momentum (directly affects the service life of the roller)
3. Flexibility (affecting the service life of the roller and the service life of the tape, as well as the driving power of the whole machine)
4. Waterproof performance (affecting the service life of the roller)
5. Dustproof performance (affecting the service life of the roller)
6. Axial load capacity (affecting the service life of the roller)
7. Impact resistance (affecting the service life of the roller)
8. Rotational resistance (affects the service life of the tape).
Use Actions
1. Before use, the roller should be carefully checked for serious bump damage to the appearance, and the rotating roller should rotate flexibly without jamming.
2. The installation distance of the idler should be determined by scientific calculation according to the type of logistics and the characteristics of the conveyor, so as to avoid over-sparse or over-dense installation.
3. The roller installation should be adapted to avoid friction between each other.
Maintenance
1. The normal service life of the roller is more than 20000h, and it generally does not need to be maintained. However, according to the size of the place of use and the load, the corresponding maintenance date should be formulated, and the oil injection maintenance should be cleaned in time, and the floating coal should be cleaned up in time. The rollers with abnormal sound and non-rotation should be replaced in time.
2. When replacing the bearing, the bearing cage opening must be outward, and after the bearing is loaded into the roller, the appropriate clearance should be maintained and not crushed.
3. The labyrinth seals should be made of original accessories, and should be packed into the idlers separately during assembly, and should not be assembled together.
4. When using the roller, it should be strictly prevented from hitting the roller body with heavy objects.
5. In order to ensure the sealing performance and use performance of the roller, it is forbidden to disassemble the roller at will.
