We received a failed rubber belt from a customer which illustrated a typical belt failure. In order to determine belt tensile capacity we conducted destructive testing of the belt. This determined the retained belt tensile, giving us an indication towards its failure mode.

A low tensile value would indicate possible belt reinforcement fatigue from the use of pulleys that are too small for the system or severe reverse bending.

A high retained tensile value would indicate a shock or overload situation. This could be the result of debris in the pulley groove, belt over-tensioning or a belt below the system’s required capacity.

TransDev has a range of power transmission belts that cover a wide capacity range. We would always advise to supply power, torque and speed information to your TransDev contact when ordering.
