Share some troubleshooting guides for K-series bevel gear reduction motors with hard tooth surfaces
The K series reducer may experience various malfunctions during use. Here are some common faults and troubleshooting methods:Overheating of gearbox
Reason for malfunction
The load is too large, exceeding the rated bearing capacity of the gearbox.
Poor ventilation and high ambient temperature.
The internal components of the gearbox are worn, generating additional heat.
Troubleshooting
Verify the load situation to ensure it is within the rated range of the gearbox and avoid overloading operation.
Choose the appropriate lubricating oil, add or adjust it according to the specified oil level, and regularly replace the lubricating oil.
Improve ventilation conditions and lower ambient temperature, such as adding cooling fans or improving installation locations.
Check internal components such as gears, bearings, etc., and replace severely worn parts in a timely manner.
The gearbox vibrates greatly
Reason for malfunction
The installation of the motor and reducer is not concentric.
The foundation of the reducer is not firm or the anchor bolts are loose.
Gear wear, broken teeth, or poor meshing.
The bearing is damaged.
Troubleshooting
Adjust the installation position of the motor and reducer again to ensure that the concentricity meets the requirements.
Strengthen the foundation of the gearbox and tighten the anchor bolts.
Check the gears, repair or replace worn or damaged gears, and adjust the gear mesh clearance.
Replace damaged bearings.
The gearbox has abnormal noise
Reason for malfunction
Gear wear, damage to the tooth surface, or impurities entering the meshing surface.
The bearing is damaged.
There are foreign objects inside the reducer.
Insufficient lubricating oil or poor oil quality.
Troubleshooting
Check the condition of the gears, clean the impurities on the tooth surface, and repair or replace damaged gears.
Replace damaged bearings.
Open the gearbox and clean up any foreign objects inside.
Add lubricating oil to the appropriate level or replace it with high-quality lubricating oil.
Gearbox oil leakage
Reason for malfunction
Seals are aging, damaged, or improperly installed.
The pressure inside the gearbox is too high.
The oil level is too high.
Deformation or impurities on the bonding surface.
Troubleshooting
Replace the seal to ensure correct installation.
Check if the ventilation plug is blocked to ensure that the internal pressure of the gearbox is normal.
Adjust the oil level to the normal height.
Clean the joint surface, repair the deformation, and apply sealant if necessary.
Abnormal output shaft speed of reducer
Reason for malfunction
Motor malfunction, such as short circuit or open circuit in the motor winding.
The internal gears of the gearbox slip or are damaged.
Other components in the transmission chain malfunction, such as damaged couplings.
Troubleshooting
Check the motor, repair or replace the faulty motor.
Disassemble the gearbox, inspect the condition of the gears, and replace damaged gears.
Check other components in the transmission chain, such as couplings, and replace damaged parts in a timely manner.
If you encounter complex problems or cannot determine the cause of the malfunction during the troubleshooting process, it is recommended to contact professional maintenance personnel or gearbox manufacturers for consultation and repair.
