Cause of Failure
– Tensile breaks can be caused by high shock
loads, foreign object between the bottom of the sheave and the
bottom of the belt or damage during installation.
Correction
– Maintain proper drive tension and installation
procedures. Provide guard to keep foreign material from
coming in contact with the drive.
Cause of Failure
– Tooth shear caused by belt overload
condition from improper application or shock loads.
Correction
– Consult engineering manual to proper application
and maintain proper belt tension.
Cause of Failure
– Fabric wear caused by insufficient belt
tension or pulleys which are not to the standard Pd pulley
dimensions and tolerances.
Correction
– Maintain proper tension and replace the
out-of-spec pulleys.
Cause of Failure
– Back of the belt has been rubbing on a belt
guard or other appurtenance.
Correction
– Provide adequate clearance between belt and
guard or any appurtenances.
Cause of Failure
– Web fabric wear caused by improper belt
and pulley fit.
Correction
– Check belt/pulley fit and replace worn or
out-of-spec pulleys.
Cause of Failure
– Worn sheave grooves allow the joined belt
to ride too low cutting through to the top band.
Correction
– Replace sheaves and maintain proper belt tension
and sheave alignment.
