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 — 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 — Excessive dust and rough sheaves combine
to cause severe envelope wear and early belt failure.
Correction — Maintain sheave condition, alignment and attempt to
protect drive from excessive dust exposure.
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.
Cause of Failure — Flange wear on PD synchronous belt.
Correction — Adjust and maintain proper pulley alignment.
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 — 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.
