Due to long-term compression, the belt will be permanently deformed and stretched, and the belt will change from tension to relaxation, and the tension will gradually decrease, and the transmission capacity will be reduced, or even it will not be able to drive. Therefore, the belt must be re-tensioned.
Adjust the pre-tightening force of the belt by changing the center distance regularly, so that the belt can be re-tensioned. In horizontal or slightly inclined transmission, the motor with pulley can be installed on the bottom plate with slideway as shown in the following figure. Push the motor to the required position on the right by turning the adjusting screw on the left, and then tighten the motor mounting screw to achieve tension.

Precautions:
When installing pulleys, the axes of the two wheels must be parallel; The center line of the wheel groove must also be aligned, otherwise it will lead to premature wear on one side of the V-belt working face.
When selecting the belt, the model and nominal length should not be mistaken to ensure the correct position in the groove of the V-belt section.
When there are a large number of V-belts in the same transmission, belts with different lengths and old belts cannot be used to avoid uneven load distribution and accelerate belt wear.
It is forbidden to contact the tape with mineral oil, acid, alkali and other media to avoid deterioration. It is also not suitable for exposure to the sun.
