Analysis of eight major faults of gear reducer

According to the staff's summary,Gear reducerThere are eight common faults in operation, which are the eight common problems, what are the causes of the faults, and how to deal with them? The following are analyzed one by one.

1: The sound of the gear reducer is abnormal or there is noise
Reason: There are many impurities in the lubricating oil; the gear meshing part is damaged, the gear gap increases, and the bearing gap is large; the bearing is damaged or worn seriously.
Remedy: Check the meshing parts. Damaged parts may need to be replaced. Adjust the bearing clearance. Replace damaged bearings.

2: Bearing temperature is too high
Reasons: the oil level in the reducer is too low; there is too little lubricating oil and the lubricating oil has aged; the bearing is damaged.
Remedy: Check the oil level at room temperature, you may need to add lubricating oil. Check when the oil was last changed. Lubricating oil may need to be changed. Check the bearings, they may need to be replaced.

Three: oil seal seepage, oil leakage
Reason: oil seal failure
Remedy: replace the oil seal. Check the wear of the shaft at the oil seal, it may need to be replaced.

4: Reducer working temperature is high
Reason: The oil level in the reducer is too high or the amount of oil is small, the oil is aging, and the lubricating oil is seriously polluted.
Remedy: Check the oil level, it may need to be corrected. Increase the lubricating oil. Check when the last oil was changed. Lubricating oil may need to be changed.

Five: tooth surface wear or corrosion
Reason: The lubricating oil is of unqualified quality or contains impurities.
Remedy: Replace worn gears and change lubricants.

Six: broken gear teeth
Reason: overload work, gear quality problem.
Remedy: Replace parts and recalculate the load to see if the selection is correct.

Seven: The input shaft is broken
Reason: The radial force is too large, the installation error of the coupling is too large, and the quality problem.
Remedy: Replace parts. When the user uses the pulley to input power, check whether the radial force exceeds the specified maximum value. Check whether the angle error of the coupling installation is out of tolerance.

Eight: the deceleration case body is cracked
Reason: Too much radial force, broken gear teeth, quality problems.
Remedy: When the user uses a chain drive to output power, it is necessary to check the radial force. If the radial force exceeds the specified maximum value, it is recommended that the user use a welded box or an enlarged model.

Through the introduction of the above eight major faults, everyone learns that they can have some simple fault analysis and resolution capabilities, and they will not be in a hurry when facing problems. More troubleshooting issues will be explained in the follow-up articles of GM, welcome to pay attention.
