Belt conveyor common reducer failure and preventive measures
Belt conveyor common reducer failure and preventive measures 1. Belt does not turn: After the motor starts, the drive roller idle belt slips, the belt does not start up, this fault is due to insufficient belt tension, the tensioning device is not adjusted, the belt is too long, Heavy load start, belt tail coal and many other reasons.

2. Belt deviation: The reason for the deviation is that the belt has lateral force during operation. The reasons for the lateral force are as follows: the conveyor is loaded on one side instead of being placed in the center position; the roller and roller are installed. The axis is not perpendicular to the center of the conveyor belt; the height of the fuselage wire rope is inconsistent; the joint of the conveyor belt is not straight or straight; the position of the unloading drum is not adjusted well; the tail roller and the guide roller are not adjusted well to cause the belt to run off.
Adjusting the running deviation is generally carried out during the running of the belt. When adjusting, pay attention to the running direction of the belt and the direction of the deviation. If the belt is deflected to the right, move the right axis of the roller in the direction of the belt running at the beginning of the belt. End, or move the left shaft end of the roller in the direction of transport, so that the left end of the roller is slightly inclined forward. When adjusting, adjust a few rollers, each roller should be adjusted less, and the adjustment amount will be too large. It will go in the other direction, and the adjustment method when the belt is turned to the left is as described above, but the adjustment direction is reversed; if the belt deviation occurs in the guide roller, the tail roller, and the unloading roller, the head frame can be adjusted, and the tail frame can be adjusted. Before the adjustment, the bolts at both ends of the drum shaft should be loosened to facilitate adjustment. After adjustment, tighten the bolts.
3. The belt is easy to disconnect: This reason is caused by excessive belt tension, weak joint, poor belt buckle quality, long belt use time, poor maintenance quality, etc. The method is to tighten the tensioning device and reduce the tension in time. Replace the new belt and enhance the quality of the repair.
4. The sound of the reducer is abnormal: this reason is caused by the excessive wear clearance of the bearing and the gear or the looseness of the screw of the shell. The treatment method is to replace the bearing, adjust the clearance or replace the overall reducer for overhaul.
5. The speed reducer is heating too fast: This reason is caused by excessive oil quantity, poor heat dissipation performance, and the speed reducer is buried by the source coal. The treatment method is to adjust the oil quantity and remove the source coal.
6. The oil leakage of the reducer: The reason is that the seal ring is damaged, the joint surface of the reducer is not flat, and the counter bolt is not tight. The treatment method is to replace the seal ring, tighten the joint surface of the box and the bolts of each bearing cover.
7. The roller does not turn: the reason is that the roller bearing is damaged. After the sealing ring on both sides of the roller enters the coal powder, it will not block and the bearing roller will be bent too much. The treatment method is to replace the roller, raise the well to repair, reduce the height difference of the drop point, or use the anti-vibration roller at the drop point.
Measures to prevent common failures of belt conveyors:
(1) In order to ensure the normal operation of the belt conveyor, in addition to the general maintenance and repair every day, we must also pay attention to daily inspections, regular maintenance, and improve the quality of repair and maintenance.
(2) Improve the professional knowledge of maintenance personnel, operate the belt conveyor correctly, and ensure the stable operation of the conveyor.
