V-belts mount to pulleys to transmit power between rotational shafts. They get their name from their V-shaped profile which fits securely in the pulley's groove. The V-belt's cross-sectional dimensions and length are key in determining the belt's proper fit and tension in a drive system. Standard and cogged V-belts are either single belts or banded, which are two or more belts fused together with a reinforced backing. Cogged V-belts run cooler than standard V-belts. Link V-belts can be sized to any length without dismantling the drive system. Metric V-belts are sized based on European standard DIN 7753 and ISO 4184. Micro-ribbed V-belts are thin and flexible and have raised ribs along the length of the belt for small, high-speed applications. Variable speed belts work with changes in drive system speeds and pulley widths.

BEHAbelt offers different versions of Twin-V-Belts. Depending on the area of use and application, the profiles can be reinforced with so-called reinforcements (polyester, aramid, steel and weldable glass fibre PU). Thanks to different Shore hardness grades, optimum transmission and conveyor properties as well as a long service life are guaranteed.


BEHAbelt uses high-quality PU (polyurethane) materials for the production of Twin-V-belts, which guarantee optimum performance and a long service life in transmission and conveyor technology applications.


Twin-V-Belts from BEHAbelt can be purchased by the metre, assembled end-to-end, delivered or welded on site.There are two ways of welding the profiles, either butt welding (for non-reinforced profiles) or overlap welding (for profiles with tension members).


For PU belts the welding temperature should be 290C; for TPE belts 240C. The welding paddle (e.g. EErgo) is held between the belt ends. Then the belt ends are pressed against the sides of the paddle by lateral pressure. The material melts. After the melting phase, the welding paddle is removed and the belt ends are pressed together with the guide clamp. After the cooling period, the belt is endlessly welded.


V-belts look like relatively benign and simple pieces of equipment. They're basically a glorified rubber band, right? Need a replacement? Just measure the top width and circumference, find another belt with the same dimensions, and slap it on the drive. There's only one problem: that approach is about as wrong as you can get.


Like their synchronous belt cousins, V-belts have undergone tremendous technological development since their invention by John Gates in 1917. New synthetic rubber compounds, cover materials, construction methods, tensile cord advancements, and cross-section profiles have led to an often confusing array of V-belts that are highly application specific and deliver vastly different levels of performance.


In this article we'll review some V-belt basics to help you make better sense of which belt to use in a given application to make your belt drives last longer, run more efficiently, and save you downtime and money.


However, notice the differences in cord materials, body compounds, cover configurations, temperature ranges and application requirements. Despite their outward similarities, each of these belts is designed for a distinct purpose. Using the wrong belt could cause equipment damage or pose serious safety issues. What is the right belt for the job? It depends on the application. Following are some environmental and application design criteria that will influence belt selection:


Unlike flat belts, which rely solely on friction and can track and slip off pulleys, V-belts have sidewalls that fit into corresponding sheave grooves, providing additional surface area and greater stability. As belts operate, belt tension applies a wedging force perpendicular to their tops, pushing their sidewalls against the sides of the sheave grooves, which multiplies frictional forces that allow the drive to transmit higher loads. (Figure 2) How a V-belt fits into the groove of the sheave while operating under tension impacts its performance.


V-belts are made from rubber or synthetic rubber stocks, so they have the flexibility to bend around the sheaves in drive systems. Fabric materials of various kinds may cover the stock material to provide a layer of protection and reinforcement.


The classical V-belt profile dates back to industry standards developed in the 1930s. Belts manufactured with this profile come in several sizes (A, B, C, D, E) and lengths (Figure 3), and are widely used to replace V-belts in older, existing applications.


V-belts with a narrow profile (3V, 5V, 8V) have more steeply angled sidewalls than classical V-belts (Figure 4), providing increased wedging action and higher load capacity (up to 3x that of comparable classical V-belts)..


Metric V-belts have profiles that adhere to international standards set by organizations such as ISO (International Organization for Standardization) and DIN (the German Institute for Standardization) (Figure 5). They are used to replace belts on industrial machinery manufactured in other parts of the world.


The fractional horsepower V-belt profile is designed for light-duty applications such as lawnmowers, snow blowers, attic or furnace fans, etc. These belts have a thinner cross-section and lighter gauge tensile cord (Figure 6), making them more flexible and able to bend around small sheaves.


Engineering a notched belt is a balancing act between flexibility, tensile cord support, and stress distribution. Precisely shaped and spaced notches help to evenly distribute stress forces as the belt bends, thereby helping to prevent undercord cracking and extending belt life (Figure 7).


For applications with vibrating or pulsating loads, especially with long center distances, joined V-belts may be the answer. A joined V-belt is, in essence, a number of single V-belts joined together with a continuous tie-band across the back (see Figure 8).


Figure 9 describes the constructional components of standard and notched V-belts. Each component has a vital role to play in how well V-belts perform and how long they last. Different materials and configurations can influence belt performance characteristics in specific applications.


The tensile cord is the load-carrying component of a V-belt. Most V-belts are made with polyester cords, although some belts are constructed with aramid or Kevlar? cords, which offer higher tensile strength, limit stretch, and can handle heavier shock loads. In a well-engineered V-belt, the tensile cords and rubber body of the belt are chemically bonded to form one unit, allowing for equal load distribution and longer belt life.


Tensile cords are supported by rubber stocks, both above (over cord) and beneath (under cord). Various synthetic rubber stocks are used by different manufacturers to provide heat resistance and reduce wear. Some high-performance synthetic rubber compounds, such as ethylene, significantly extend a belt's operating temperature range and resist hardening, cracking, and premature failure.


A well-engineered V-belt will have transverse rigidity, which means a high level of rigidity across its width so that the tensile cords will transfer the load equally. At the same time, the belt must be highly flexible along its length to reduce heat and bending stresses, which in a superior belt is accomplished by parallel alignment of fibers in the rubber compound.


Adhesion gum is the element that forms a strong chemical bond between the tensile cord and the rubber stock. It bonds the belt together so that it acts as a single unit. The gum also absorbs cord stresses and avoids cord pullout.


To protect the core of the belt from destructive environmental forces such as oil, grime and heat, as well as from general wear and tear, some V-belts have a fabric cover, or band ply. In a well-engineered belt, this flexible fabric is treated to form a chemical bond with the belt core materials, allowing it to withstand the stress of constant bending over time and prolonging cover life. 041b061a72
