What are the advantages of V-ribbed belts over traditional V-belts

The engine belt is an invisible small part of the truck engine. Although it is small, it is responsible for transmitting power to accessories such as water pumps, generators, cooling fans, and air-conditioning compressors. It can be said that the actions of various components in the engine are connected. Without it, our truck can't walk a step, and it may also cause serious failures such as engine scrapping. Let's learn about it together.multi-wedge beltWhat are the advantages compared to the traditional triangle belt!

So far, almost all the V-belt used in the engine, but with the development and progress of technology in recent years, the V-ribbed belt has replaced the V-belt as the mainstream now. However, although most people know that the V-ribbed belt is better than the V-belt, we are not sure what is good, so today we will take a look at why the V-ribbed belt can replace the V-belt.

Before the popularity of the multi-wedge belt, the V-belt was widely used, and its shadow can be seen on many mechanical devices. It has the characteristics of low price, simple process and low technical content, and the precision of the belt groove is also very low. However, there are advantages and disadvantages. The transmission capacity of the V-belt is relatively low, and the service life is relatively short. It is difficult to meet the needs of modern engines. Although it has begun to be gradually eliminated, its substitute V-ribbed belt has many advantages.

The 1.V-ribbed belt has a large contact area with the pulley, the load distribution is uniform, and the transmission capacity is stronger. It has about 30% more transmission power than the ordinary V-belt.

The 2.V-ribbed belt drive has relatively small vibration, stable operation, small elongation for long-term use, long life, belt speed of 40 meters per second, and high power.

The 3.V-ribbed belt has a thin body, good flexibility, low working stress and low heat generation, and can work through a small diameter pulley. Under the same power, the V-ribbed belt can effectively reduce the volume of the transmission parts, and the occupied space is about 25% smaller than that of the traditional V-ribbed belt.

4. the V-ribbed belt is also a favorite of engine manufacturers, but because the back of the V-ribbed belt can also be driven, a more complex transmission system can be configured in a smaller space, and more equipment can be driven in a limited space. In addition, the use of automatic tension adjuster can make the transmission more safe and reliable.

As described above, the V-ribbed belt is advanced, but it does not mean that the V-ribbed belt will not fail. Generally speaking, the failure of the V-ribbed belt In most cases, if the tension is too small or too large, it will cause the belt to be damaged. Inspection and maintenance have a great influence on the life of the belt. I hope to pay attention to the state of my engine belt in the gap of the car to prevent damage caused by damage during operation.

The above introduction ismulti-wedge beltCompared with the traditional V-belt, many advantages of V-ribbed belt have replaced the V-belt. Of course, with the increasing development of science and technology today, we believe that more advanced transmission systems will appear in the future, and future engines may not need belts.

Cut three samples with a length of 250 mm from one PJ V-ribbed belt, and mark a marking line with a spacing of 100mm at the middle position of the PJ V-ribbed belt. When more than three samples cannot be taken from one PJ V-ribbed belt, samples can be cut from the same batch of PJ V-ribbed belt, but must be indicated in the report. 7.4.2 High temperature resistance test method
Place the sample at 100 ℃ ± 2 ℃ for 96 h ± 1 h and then take it out. After standing at laboratory temperature for more than 2h, bend it along a cylinder with a diameter of 20 mm at a contact angle of at least 90 °.
