The root cause of the deviation of the belt is that the combined force of the external force of the tape in the belt width direction is not zero, or the tensile stress perpendicular to the belt width direction is uneven, resulting in the reaction force of the roller or the roller on the belt. A component force to one side, which causes the belt to shift to one side under the action of this component. The common deviation phenomenon is as follows.
1. Analysis of the reasons for belt deviation
The center of the nose, tail, and intermediate frame does not run off the belt in a straight line.
This situation is usually caused by the installation. Since the centers of the three are not in a straight line, the longitudinal centerline of the belt is not perpendicular to the axis of the drum, causing the belt conveyor to run off during operation.
The installation position of the drum does not cause the belt to run off at the drum.
A belt conveyor has multiple rollers. All rollers must be installed at a position perpendicular to the centerline of the tape and parallel to the horizontal plane. If the installation level of the roller is not enough, the roller is axially tilted, or one end of the roller is at the front end. Therefore, the installation position of the drum and the longitudinal center line of the tape are not perpendicular, or the axis of the drum is not parallel to the horizontal plane, and the combined force of the external force of the belt in the belt width direction is not zero, and the belt will deviate in the direction indicated by the resultant force.
