Thanks to our extensive technical and application experience in the development and production of drive elements and systems for transmissions in the industrial sector, DINAMICA offers the best range of V-belts, including customized products for any specific requirement.

The availability of high-tech products, in-depth knowledge of materials and processes, combined with the ability to design and manufacture complete belt and pulley drive units, make us the ideal partner for manufacturers of industrial machinery and equipment.

What should I know about V-belts and pulleys?

Before discussingbeltsandV-belts, we should be clear about whatbelts areinthe industrial field. The first thing we need to know is thatbeltsarepowertransmissionelements made of flexible materials so that they can be fitted ontopulleys to transmit torque.

Thanks to the flexible materials usedto manufacturethebelts, installation is relatively simple. These types ofbeltsoperateby friction with thepulleysonwhich they are mounted, and they also help to reduce vibrations between the drive shafts. It should be noted that the use offlat beltsdoes notalways ensure constant transmission at all times, as we may experience slight movements of thebeltonthepulleys for various reasons, such as wear and tear during operation or incorrect initial tensioning. This problem is solved by usingV-belts.

Now that we have a clearer understanding ofbelts, let's focus onV-belts, also known asV-sectionbelts, which allow us to transmit higher torque thanflatbelts. In addition,V-beltsallow us to achievehigher linear speeds, reaching up to 30 m/s without any problems.

We should also highlight other characteristics ofV-belts, namely that they have been designed to operate without maintenance, meaning that they do not need to be retensioned or lubricated. In addition,V-belts are availablewithorwithoutribs, making them ideal for better resistance to wear, heat, and corrosion.

As forV-belts, we should know that they are specifically designed to fitV-belts and can be used in all types of machinery that have shafts. Their operation is linked to that ofV-belts, and in the same way, they are responsible for transferring power through a shaft and thecorrespondingV-belts. It should also be noted thattrapezoidalpulleysarewidely used in sectors such as the automotive industry, where in many cases they are superior to other types ofpulleys.

Types of V-belts and pulleys

When discussingV-belts, we must bear in mind that there are various types ofbelts available, and we need to understand them in order to know which one best suits our needs.

We must bear in mind thatV-belts can be classifiedintotwo main groups. On the one hand, we haveclassicV-belts,including Z, A, B, C, and Dwrapped belts, andZX, AX, BX, and CXtoothed belts. On the other hand, we havenarrowV-belts, including SPZ, SPA, SPB, and SPC wrappedbelts.

If we focus onclassicV-belts, the first thing to note is that they are themostcommontype of belt and the ones that have traditionally been used the most. Thesebeltshavebeen used in a wide variety of industrial applications, whether in sectors such as agriculture, ventilation machinery, or various types of industrial machinery. We should also note thatclassicV-belts can handle loads of up to 500 horsepower, and although they are somewhat less efficient thannarrowV-belts, they are more resistant than the latter.

When discussingnarrowV-belts, the first thing to know is that they are particularly useful for load transfer and force distribution, as they have a better depth-to-width ratio than traditional belts. This is undoubtedly the main advantage ofnarrowV-beltsoverclassic ones, as we saw earlier, butnarrowV-belts canalsoreach higher transmission speeds and can even operate at 1,000 horsepower.

Whenit comestoV-belts, we must distinguish betweenblindV-beltsandV-beltsfortaperedbushings.

Dinámica timing belt catalog

InDinámica'sextensive catalog ofV-beltsand pulleys, you will find the following options for all your needs:

• SIT EXCELITE®ES Classic and Narrow V-Belts and Pulleys,whichcan be used in a wide range of industrial and agricultural applications, and have been designed to ensure high reliability, excellent durability, and an optimal performance-to-price ratio.
• SIT TORQUE FLEX Classic Die-Cut Beltsand Pulleys, specifically designed to operate at high speeds, especially on small diameter pulleys and short center distances.
• RMA SIT V-belts and pulleys,madeof leather and featuring the Matchmaker system, which guarantees better production tolerance.
