Common Causes of Gear Failure in Industrial Machinery

Unexpected gear breakdown increases production loss and maintenance expenses. Most failures occur due to lubrication issues, overload or improper installation.

1. Improper Lubrication

• Metal to metal contact
• Rapid heat generation
• Surface cracking

2. Overloading

Operating beyond design torque causes bending stress and sudden tooth breakage.

3. Shaft Misalignment

• Noise increase
• Vibration
• Uneven wear

4. Poor Material Quality

Improper heat treatment and low hardness lead to premature gear failure.

5. Contamination

• Dust particles
• Metal debris
• Moisture

Conclusion

Regular inspection and correct gear selection significantly reduce breakdown risk.
