The Structure of the Drive Pulley and the Reversing Pulley

The structure of the drive pulley and the reversing pulley should be selected based on the load capacity.

The selection of the drum surface type should meet the following requirements:
1. The surface type of the drive roller should be selected based on factors such as the transmitted tangential force and working conditions.
When the transmitted circumferential force is large, the working environment conditions are poor, and the ambient temperature is low, rubber-covered drive rollers should be used.
For small conveyors with relatively low circumferential force transmission and good working environment conditions, smooth-surface drive rollers can be used;
In case of special requirements, other surface types can be used;
2.  The rubber-covered drive roller should have V-shaped grooves or diamond-shaped grooves. The drive rollers that operate in both directions should have diamond-shaped grooves;
3.  For redirect rollers that are exposed to poor working conditions or in contact with the conveyor belt's load-bearing surface, rubber-covered rollers should be used;
4.  The rubber surface properties of drive rollers and reversing rollers used in coal mines or cold environments should meet the requirements of the working environment.

The load conditions of the drum should comply with the following requirements:
The load on the drive roller can be calculated based on the torque and combined tension experienced by the drive roller during the stable operation of the conveyor.
For important conveyors with large transport capacity, high lifting height, and complex layouts, the drive rollers should be selected based on the most adverse load conditions in various operating scenarios.
The load on the 2-way transfer roller can be calculated based on the load conditions of the conveyor's stable operating state to determine the combined tension. For important high-tension conveyors, the maximum value should be taken from various operating conditions.

The diameter of the electric roller, the surface type of the roller, and the load conditions can be selected according to the specifications for the drive roller.
