The most typical systems for transmitting power from a drive to a driven shaft are belt, gear, and chain drives. But V-belt drive systems, also known as friction drives (because power is V Belt usually transmitted as a result of the belt’s adherence to the pulley) are an economical option for industrial, automotive, commercial, agricultural, and home appliance applications. V-belt drives are also easy to install, need no lubrication, and dampen shock load.
Here’s the catch: Standard friction drives can both slide and creep, leading to inexact velocity ratios or degraded timing precision between input and output shafts. Because of this, it is essential to select a belt befitting the application at hand.
Belt drives are among the earliest power transmission systems and were widely used during the Industrial Revolution. Then, flat belts conveyed power over large distances and were made from leather. Later, needs for more powerful machinery, and the development of large markets like the automobile sector spurred new belt styles. V-belts, with a trapezoidal or V shape, made of rubber, neoprene, and urethane synthetic materials, replaced flat belts. Now, the improved overall surface area material of contemporary belts adheres to pulley grooves through friction pressure, to reduce the tension necessary to transmit torque. The very best section of the belt, known as the strain or insulation section, contains fiber cords for improved strength since it carries the load of traction push. It helps hold tension members set up and acts as a binder for greater adhesion between cords and other sections. This way, heat build-up is reduced, extending belt life.
We’ve designed our V-belts for wear, corrosion, and heat resistance with OE quality match and building for reliable, long-enduring performance.
V-Belts are the most common kind of drive belt used for power tranny. Their primary function is certainly to transmit power from a major source, just like a engine, to a second driven unit. They offer the best combination of traction, acceleration transfer, load distribution, and extended service life. The majority are unlimited and their cross section is definitely trapezoidal or “V” shaped. The “V” shape of the belt tracks in a likewise designed groove on a pulley or sheave. The v-belt wedges into the groove as the load increases creating power distribution and torque. V-belts are commonly made of rubber or polymer or there may be fibers embedded for added power and reinforcement.
V-belts are generally within two construction groups: envelope (wrapped) and raw edge.

Wrapped belts have an increased resistance to oils and severe temps. They can be used as friction clutches during set up.
Raw edge type v-belts are better, generate less heat, allow for smaller pulley diameters, enhance power ratings, and provide longer life.
V-belts look like relatively benign and simple devices. Just measure the top width and circumference, discover another belt with the same sizes, and slap it on the drive. There’s only one problem: that approach is approximately as wrong as you can get.
