Troubleshooting Hints

TROUBLE SHOOTING HINTS
PROBLEM POSSIBLE CAUSES OF PROBLEM SUGGESTED REMEDY
Fracture Plate Overloading Inspect the drive to determine the cause of high load and eliminate
Or
Redesign drive for larger pitch chain
Broken Pins Overloading Inspect the drive to determine the cause of high load and eliminate
Or
Redesign drive for larger pitch chain
Broken Pins(Centre) Loading is greater than pin’s dynamic capacity Inspect the drive to determine the cause of high load and eliminate
Or
Redesign drive for larger pitch chain
Broken Pins(Offset Pin) Overloading Single pitch offset link is to be eliminated Redesign drive using a higher capacity chain
Fatigue Failure Loading is greater than chain’s dynamic capacity Single pitch offset link is to be eliminated Redesign drive using a higher capacity chain
Cranking Stress corrosion cracking Replace chain, reduce speed Use larger sprockets or possibly redesign drive for small sprocket
Broken Roller Speed too high Sprockets too small Chain riding too high on sprocket teeth Inspect the drive to determine the cause of high load and eliminate
Or
Redesign drive for larger pitch chain
Worn Contour Chain rubbing on casing, guide or obstruction Replace chain if 5% or more height worn out Inspect and redesign casing, guide and eliminate interference
Pin or Bushing Galling Speed or load too high Inadequate lubrication Reduce speed or load Redesign drive for smaller pitch chain Provide proper lubrication system.
