How to avoid the lock-up of the reducer

When we encounter the situation that the granulator cannot be started during the production process, if it is confirmed that it is not a power problem, it may be caused by the locking problem of the granulator reducer, and the main reason for this phenomenon is the lubrication system. The problem is that there is no or lack of lubricating oil. Another reason is that the long-term overload operation of the equipment causes the high temperature of the reducer, resulting in lockup.

How to confirm whether the gear reducer of the ring die pellet machine is locked?

Usually, we need to remove the coupling between the motor and the reducer first, observe whether the motor can run normally, eliminate the fault of the motor, and then move the input shaft of the reducer. If it is found that it cannot rotate, the reducer can basically be identified. If there is a lock, the reducer must be repaired or replaced.

1. Usually observe the oil pressure, oil temperature, and flow rate of the reducer of the ring die pellet machine. If it is found to be abnormal, it needs to be shut down, and the filter and nozzle should be cleaned. After cleaning, check the lubrication before it can be used.

2. The bearing lubrication of the reducer of the ring die pellet machine should be in the form of splash lubrication. When disassembling, washing and reinstalling, it is necessary to add appropriate grease, which is about 1/3 of the bearing space volume.

3. When it is found that the air hole of the reducer of the ring die pellet machine is blocked, the power of the equipment should be turned off, and the filter should be removed and replaced for gas cleaning, and then turned on for operation.

4. When the damaged area on the tooth surface exceeds 20% along the tooth length direction and the tooth height direction, the gears should be replaced in pairs. After the replacement, the running-in and load test should be carried out. The tooth length touching 60% and the tooth reaching 40% can be officially used.

5. When the ring die pellet machine is working, if it is found that the temperature of the reducer oil has risen above 80°C or 100°C, and abnormal noise occurs, the power of the main engine should be turned off, checked, and the lubricating oil should be replaced to eliminate the fault before continuing. run.

6. The output shaft of the reducer of the ring die pellet machine does not rotate when it is rolling. It may be that the key coupling of the reducer is damaged, and the reducer must be disassembled for inspection.
