These are the most commonly used V belts for power transmission. At the same level of tension, they transmit higher power than flat belts. They are used, for example, in variable-speed drives. They offer the best combinations of traction, speed, bearing load and service life.

Advantages:

• The V-shaped section of the belt follows a groove in the pulley, which prevents the belt from slipping and improves torque transmission.
• It is less wide than a flat belt and therefore takes up less space.
• It doesn’t need to be as taut.
• The optimal speed range is between 300 and 2,130 m/min.
• For high power requirements, two or more V belts can be assembled side by side in an arrangement called a “multiple belt drive.”

V belts, also called trapezoidal belts, can be made of rubber or polymer without reinforcement, or they can have fibers incorporated into the rubber or polymer to increase strength. These fibres can be made of textile material (such as cotton), polyamide (such as nylon), polyester or, for greater strength, steel or aramid (such as Kevlar).

When a seamless belt does not meet the requirements of the application, articulated V belts can be used. Most models offer the same power and speed as endless belts of the same size and do not require special pulleys to operate. They are easy to install and have a higher environmental resistance than rubber belts. They are also adjustable in length if you choose to remove the links.
