V-belts are belts used very frequently to transmit the desired power, solving the problem of slippage and alignment, and guaranteeing the system the right combination of traction, speed, tension on the supports and durability. One of the reasons for this advantage lies precisely in the particular shape of the belt, housed in the V-shaped groove of the pulley, capable of guaranteeing an excellent contribution in terms of protection against radial slippage. Furthermore, as the load increases, the belt is able to sit more in the hole, increasing friction and improving power transmission.
Ribbed belts, on the other hand, are certainly more complex and are made by joining a group of V-belts (5 or more). In this way, with the same friction, it will be possible to obtain a thinner and more flexible belt, increasing its efficiency, reducing overheating and consequently obtaining significant advantages in terms of increased durability over time.
In addition to the above, the flexibility achieved through this type of belts allows the use of a single belt to transmit the desired power to multiple accessories, creating complex routes.
In other words, these specific straps can guarantee all typical advantages of flat belts and V-belts, but at the same time, with the same width, they can present a height of approximately half compared to normal V-belts. In extremely synthetic words, they are an intermediate solution between belts and chains, and are made from highly resistant elements such as Kevlar: the toothed part is coated with other materials (such as polyamide) to increase wear resistance.
Still different from the belts presented in our study today are those synchronous , which have grooves running transversely along the length: this specific category of belt operates differently from traditional belts, as it acts through contact between the sides of the grooves and the seats of the pulley. Normally, the teeth of synchronous belts have a trapezoidal or curved profile, and generally the traction elements and teeth are made differently.
In conclusion, we can only make a final reference to the first type of belt available on the market, which is flat , used to a greater extent to transmit energy in factories, pumps and generators, allowing the transmission of even high powers and even at high speed. On the other hand, this type of belt typically requires high pretension.
Furthermore, as they tend to run up the highest side of the pulley, these belts are usually made with a slightly convex surface, which can allow for high centralization. Made from rubber or plastic, they are joined after half a turn to distribute wear on both sides: the union can be carried out using some easy-to-apply systems (it is not excluded that they are made already closed).
