The most typical V Belt systems for transmitting power from a drive to a driven shaft are belt, gear, and chain drives. But V-belt drive systems, also called friction drives (because power is transmitted as a result of the belt’s adherence to the pulley) are an economical option for industrial, auto, commercial, agricultural, and house appliance applications. V-belt drives are also easy to install, require no lubrication, and dampen shock load.
Here’s the catch: Standard friction drives may both slide and creep, resulting in inexact velocity ratios or degraded timing precision between input and output shafts. Because of this, it is essential to select a belt appropriate for the application at hand.
Belt drives are among the earliest power transmitting systems and were trusted through the Industrial Revolution. After that, smooth belts conveyed power over huge distances and were created from leather. Later, demands for better machinery, and the development of large markets like the automobile sector spurred new belt styles. V-belts, with a trapezoidal or V shape, manufactured from rubber, neoprene, and urethane synthetic materials, replaced flat belts. Now, the improved overall surface material of modern belts adheres to pulley grooves through friction drive, to lessen the tension required to transmit torque. The very best area of the belt, known as the tension or insulation section, includes fiber cords for improved strength since it carries the strain of traction force. It helps hold tension members set up and acts as a binder for higher adhesion between cords and other sections. This way, heat build-up is decreased, extending belt life.
We’ve designed our V-belts for wear, corrosion, and heat resistance with OE quality suit and structure for reliable, long-long lasting performance.
V-Belts are the most common kind of drive belt used for power tranny. Their primary function is to transmit power from a main source, just like a engine, to a second driven unit. They offer the best mixture of traction, rate transfer, load distribution, and extended service life. Most are unlimited and their cross section is trapezoidal or “V” formed. The “V” shape of the belt tracks in a likewise shaped groove on a pulley or sheave. The v-belt wedges into the groove as the strain improves creating power distribution and torque. V-belts are generally made of rubber or polymer or there may be fibers embedded for added strength and reinforcement.
V-belts are generally found in two construction categories: envelope (wrapped) and raw advantage.

Wrapped belts have an increased level of resistance to oils and extreme temps. They can be utilized as friction clutches during set up.
Raw edge type v-belts are better, generate less heat, enable smaller pulley diameters, increase power ratings, and offer longer life.
V-belts appear to be relatively benign and basic devices. Just measure the top width and circumference, find another belt with the same measurements, and slap it on the drive. There’s only 1 problem: that strategy is approximately as wrong as possible get.
