Sealing roller 07R

The roller is an important part of the belt conveyor. There are many types and large quantities, which can support the weight of the conveyor belt and the material. It accounts for 35% of the total cost of a belt conveyor and generates more than 70% resistance, so the quality of the roller is particularly important. It is available in steel and plastic.

The role of the roller is to support the weight of the conveyor belt and the material. The operation of the roller must be flexible and reliable. Reducing the friction between the conveyor belt and the rollers plays a key role in the life of the conveyor belt, which accounts for more than 25% of the total cost of the conveyor. Although the roller is a small part in the belt conveyor and the structure is not complicated, it is not easy to manufacture high-quality rollers.

There are several criteria for judging the quality of the idler: the amount of radial runout of the idler; the flexibility of the idler; the amount of axial movement.

The roller drives the roller tube, the bearing seat, the outer ring of the bearing, and the seal ring to rotate through the friction between the conveyor belt and the roller, and realizes the transmission of logistics together with the conveyor belt.

Influencing factors:

1. Roller radial runout (this index directly affects the stability of material conveying)

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 roller)

5. Dustproof performance (affecting the service life of rollers)

6. Axial bearing capacity (affecting the service life of roller)

7. Impact resistance (affecting the service life of rollers)

8. Rotation resistance (affecting the service life of the tape)
