Maintenance
Keeping couplings in service
A correctly sized, correctly specified gear coupling still fails early if it is lubricated, aligned or inspected incorrectly. Maintenance is where most of the avoidable failures in the failure-analysis cluster actually originate — grease starvation, alignment drift and missed inspection intervals cause more early failures than any design or standards issue.
This cluster covers in-house maintenance practice: grease specification and re-lubrication intervals by size and speed, the installation and alignment procedure used at commissioning, recommended inspection intervals by duty and industry, and a step-by-step disassembly procedure for when a coupling has to come apart.
The lubrication and installation articles are written as procedures rather than overviews.
