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 called friction drives (because power is 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 simple to install, need no lubrication, and dampen 
shock load.
Here’s the catch: Standard friction drives may both slide and creep, leading to inexact velocity ratios or degraded timing precision V Belt between input and output shafts. For this reason, it is important to select a belt befitting the application accessible.
Belt drives are among the earliest power tranny systems and were widely used during the Industrial Revolution. After that, flat belts conveyed power over large distances and were made from leather. Later, demands for more powerful machinery, and the growth of large markets like the automobile sector spurred new belt designs. V-belts, with a trapezoidal or V shape, made of rubber, neoprene, and urethane synthetic materials, replaced toned belts. Now, the increased overall surface area material of modern belts adheres to pulley grooves through friction power, to reduce the tension necessary to transmit torque. The top section of the belt, called the tension or insulation section, contains fiber cords for improved strength as it carries the strain of traction power. It can help hold tension members set up and acts as a binder for higher adhesion between cords and additional 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 fit and building for reliable, long-long lasting performance.
V-Belts are the most common type of drive belt used for power transmitting. Their primary function is certainly to transmit power from a principal source, just like a motor, to a secondary driven unit. They provide the best combination of traction, speed transfer, load distribution, and extended service life. Most are limitless and their cross section can be trapezoidal or “V” shaped. The “V” shape of the belt tracks in a similarly shaped groove on a pulley or sheave. The v-belt wedges into the groove as the load boosts creating power distribution and torque. V-belts are commonly manufactured from rubber or polymer or there could be fibers embedded for added strength and reinforcement.
V-belts are generally found in two construction classes: envelope (wrapped) and raw edge.
Wrapped belts have an increased resistance to oils and intense temps. They can be used as friction clutches during set up.
Raw edge type v-belts are better, generate less heat, enable smaller pulley diameters, enhance power ratings, and offer longer life.
V-belts appear to be relatively benign and basic devices. Just measure the top width and circumference, discover another belt with the same sizes, and slap it on the drive. There’s only 1 problem: that strategy is approximately as wrong as possible get.
