The wear of the Rubber Timing Belt is related to a number of factors, dust or dirty operating conditions, wear or rough pulley, varying load, insufficient tension, pulley dislocation, belt jitter, especially the engine high temperature environment will affect the belt wear , Performance will be reduced.
In the case of regular maintenance, you should check whether the V tape has the following conventional failure modes:
Side flashes or smooth
● Relaxed belt in the pulley in the friction will make the two sides of the belt becomes smooth and shiny, smooth surface makes the belt friction coefficient is reduced and easier to slip, in the pulley of oil or grease can also cause This situation.
crack
• All the belts are cracked on a small pulley after a period of time. The reason is that the bottom rubber is continuously squeezed to produce large stresses to reach the point of rupture. Early relatively small irregular cracks usually indicate the belt Has been hardened, probably due to high temperatures.
Fall off
● The loss of the belt is due to the crack deepened to the position of the tension line caused by the whole block off, the last piece of the whole piece split, can not pass the required load.
Layered
● The stratification of the belt may be due to the oil leakage of the engine. The oil will weaken the adhesion of the rubber compound, resulting in a decrease in the adhesion between the rubber, the rope and the top of the canvas, and the final belt will slip or break, The new belt to remove the source of oil pollutants.
Side sawtooth marks
• The side sawtooth marks or pits of the belt are caused by rough surfaces in the pulley, such as gravel or pulleys, and regular cleaning of the drive parts helps to prevent such problems.
Rally break
● Large foreign bodies in the pulley may be cut into the Rubber Drive Belts and cause the rupture of the tension line. It may also be forced by the external force during the installation. The tension line is damaged and not detected until the belt is finally broken and the belt is broken May be due to bear too much tension and sustained mutations caused by the load.
