1. The polyurethane timing belt is broken.

The inertial force of the driven wheel and the passive load is not considered. The load is too large or the driven wheel stops due to an accident, which greatly increases the load force. The pulley is too small and the belt bends too hard.

2. The polyurethane timing belt is worn out.

Edge wear: The parallelism of the wheels is not accurate, the bearing rigidity is insufficient, the ribs of the pulleys are bent, and the diameter of the pulleys is smaller than the width of the belt.

Tooth surface wear: the load is too large, the belt tension is too large, the abrasive powder layer is mixed, and the teeth are rough.

3. The polyurethane timing belt tooth breaks off.

Tooth skipping, passive mechanical accident load increases.

4. The colloid on the back of the polyurethane timing belt is worn or cracked.

The rotation of the outer tensioning wheel is blocked, the positioning of the outer tensioning wheel is out of alignment, and it hits the frame of the machine, and it is in a low temperature state for a long time.

5. Loud running noise.

The tension of the polyurethane timing belt is too large, the parallel misalignment of the two shafts, the width of the polyurethane timing belt is greater than the diameter of the pulley, the load is too large, and the meshing between the polyurethane timing belt and the pulley is poor.
