Coupling Maintenance And Failure


Coupling maintenance requires periodic inspection of each coupling,which ensures proper operation of the coupling and the machine, thereby reducing downtime. It includes:

Coupling Maintenance

• Perform a visual inspection to check for signs of wear or fatigue. 
 Clean the clutch regularly. 
 If the coupling is lubricated, check and replace the lubricant regularly. 
 Most couplings require annual maintenance, and more frequently in harsh environments or harsh operating conditions. 
 Record the maintenance performed on each coupling and the date.

Coupling Failure Reason

However, even with proper maintenance, the clutch can fail. In addition to maintenance, root causes of failure include:

 Improper installation
 Improper selection of coupling
 Operation beyond design capability.

Coupling Failure

The only way to improve the life of the coupling is to understand what is causing the failure and correct it before installing a new coupling. Some external indications of a potential coupling failure include:

 Unusual noises, such as squeaks, screams, or rattles
 Excessive vibration or shaking
 Lubricant leakage or contamination indicates seal failure
