What Are The Advantages of Multi-V Belts? Long Life And High Transmission Power

The engine drive belt is an inconspicuous small component on the truck. Although it is small, it is responsible for transmitting power to accessories such as water pumps, generators, cooling fans, and air conditioning compressors. Without its normal operation, our trucks will be difficult to move, and may even cause serious failures such as engine scrapping. In the past, most of the transmission belts used in engines were V-belts. In recent years, with the development of technology, multi-V belts have gradually replaced V-belts and become the current mainstream. However, most people only know that multi-V belts are better than V-belts, but few people can tell where they are better. So, let's find out today why multi-V belts are more popular. V-belts are eliminated and multi-V belts become mainstream. Before the popularization of multi-V belts, V-belts were the most widely used, and they can be seen on many mechanical equipment. It has the characteristics of low price, simple process, and low technical content. In addition, it has low requirements for the precision of belt grooves. However, there are pros and cons. The ability of V-belts to transmit power is not very strong, and the life is relatively short. It is difficult to meet the use requirements of modern engines and has been eliminated. But its replacement, the multi-V belt, has many advantages:

First, the multi-V belt has a larger contact area with the pulley, the load is evenly distributed, and the transmission capacity is greater, which can transmit about 30% more power than the ordinary V-belt.

Second, the multi-V belt is thin, flexible, has low working stress, and correspondingly generates less heat, so it can work on a pulley with a small diameter. Under the same transmission power, the multi-V belt can effectively reduce the volume of the transmission components, and the space occupied can be about 25% smaller than that of the ordinary V-belt.

Third, the multi-V belt has low transmission vibration, stable operation, small elongation after long-term use, and a linear speed of up to 40 meters per second, with high efficiency and long life.

Fourth, the back of the multi-V belt can also transmit power, and a more complex transmission wheel system can be easily arranged, thereby driving more equipment in a limited space.

Although there are many advantages, maintenance is also required

The multi-V belt is advanced, but it does not mean that it will not fail. In general, most of the failures of the transmission belt are caused by neglect of maintenance. For example, too little or too much tension will cause early damage to the belt. The later inspection and maintenance have a great impact on the life of the belt. I hope everyone will pay more attention to the condition of their engine belt during driving to prevent damage during operation.

The many advantages of the multi-V belt make it replace the V-belt and become the most widely used transmission belt at present. However, we should believe that with the development and progress of technology, more advanced transmission belt systems will appear in the future, and it is even possible that future engines will not need transmission belts at all.
