V-BELT

What is a V-belt?

The V-belt is a type of belt used in many applications to transmit power. As the name suggests, it is a belt in the shape of a trapezoid (V). V-belts are often used in industrial applications where large amounts of power need to be transmitted over long distances. V-belts can generally be found in the following applications:

•  

  Industrial machines: they are used in industrial machines such as compressors, machine tools, presses, conveyors and pumps. V-belts are used to transfer power from motors to the various parts of these machines.
  
• Automobiles: V-belts are used to drive accessories such as alternators, water pumps, power steering pumps and air-conditioning compressors.
  
• Household appliances: used in domestic appliances such as washing machines, tumble dryers, lawnmowers and fans. V-belts help transmit motor power to the various parts of these appliances.
  
• Agricultural equipment: V-belts are used in agricultural machinery, such as combines, tractors and irrigation equipment, to transmit power to the various components.
  
• General power transmission applications: V-belts are also used in a variety of other power transmission applications, such as textile machinery, ventilation systems and air-conditioning equipment.Comme vous pouvez le constater, ce type de courroies joue un rôle primordial dans les machines et applications qui nous entourent.

What are the different types of V-belts?

There are different types of V-belts, which you can find here:

Smooth V-belt :

A smooth V-belt, as the name suggests, has a smooth, V-shaped cross-section. This shape enables it to follow the groove in the pulley, thus preventing slippage. This type of belt transmits power mainly by adhesion and friction between the belt surface and the pulley.

Toothed V-belt :

A V-belt has a V-shaped cross-section and a series of notches. These notches fit into the corresponding grooves on the pulleys, creating a positive and precise connection between belt and pulley. This composition ensures efficient, precise power transmission and prevents slippage during transmission.

Multi-strand V-belt :

A multi-strand V-belt, also known as a multiple, is a belt made up of several V-belts. These individual V-belts are connected in parallel by a strong connecting band. This shape ensures high reliability, load capacity and strength.

PolyFlex V-belt :

PolyFlex V-belts are trapezoidal belts with a ribbed top. These belts are narrower and thinner than conventional V-belts. This product is designed to save space while transmitting high loads at high speeds.

How to choose your V-belt?

To identify the belt you need, you'll need to know its part number and/or dimensions. The part number is usually written directly on the belt if it's not too damaged. If the part number is not visible, you'll need to take the dimensions. For smooth, notched and PolyFlex V-belts, you need to know the cross-section (width x height) and length. For multi-strand V-belts, you need to determine the cross-section of one strand, the number of strands and the length.
