Broken shaft problem of popular belt speed reducer for popular belt conveyor manufacturers:
Reducer shaft breakage occurs on the high speed shaft of the reducer. The most common is the use of high-speed shafts with the first stage of the reducer being a vertical bevel gear shaft. There are two reasons for the broken shaft.
1) The high speed shaft of the reducer is not strong enough in design.
This situation usually occurs at the shoulder of the shaft. Because there are transitional fillets here, fatigue damage is very easy. If the fillet is too small, the reducer will break the shaft in a short time. Qi.
When this happens, the reducer should be replaced or the design of the reducer should be modified.
2) The motor shaft is not concentric with the high speed shaft of the reducer.
When the motor shaft is not concentric with the high speed shaft of the reducer, it will increase the radial load of the reducer input shaft and increase the bending moment of the shaft. Long-term operation will cause shaft breakage. During installation and maintenance, its position should be adjusted carefully to ensure that the two axes are concentric. In most cases, the motor shaft does not break, because the material of the motor shaft is generally 45 steel. The shaft is relatively thick and the stress concentration is better.
Correct installation, operation and reasonable maintenance can maximize the performance of the belt conveyor. Please leave a message to communicate your problems.
