How to identify the failure of V-belt?

V-belt is mainly responsible for the transmission power of machinery. As long as there is operation, V-belt is indispensable. Therefore, with the development of mechanization, it has been applied in all walks of life, such as automobile industry, agricultural machinery industry, air conditioning industry, machining industry, ship absenteeism industry, etc. At the same time, the V-belt is also a rubber product, which is a vulnerable part. The most common problem in the process of use is the failure. So, how do we identify whether it is failure? Today, Hebei Heiyi rubber manufacturer will introduce it to you.

1.Skidding, no power transmission. When the working load exceeds the pulling force of the belt drive, the V-belt and the pulley slide along the whole working face, which proves that the V-belt drive is invalid.

2. Fatigue fracture of V-belt. The stress on any cross section of the V-belt will change in two cycles with the belt running. When the stress cycle reaches a certain number of times, that is, after a certain period of movement, the local fatigue crack delamination will appear. Then the conveying state or even fracture occurs, resulting in fatigue damage and loss of transmission capacity.

3. The working face of V-belt is worn. Once the working face of the V-belt is worn, it will lead to the uneven force of the belt in the process of operation, resulting in failure.

4. Torsional vibration of driven shaft. When the crack deepens to the position of the tension line, the rubber layer will peel off, resulting in the rubber layer falling off of the V-belt, resulting in unstable transmission and torsional vibration of the driven shaft.
