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 certainly transmitted consequently of the belt’s adherence 
to the pulley) are an economical option for industrial, automotive, commercial, agricultural, and house appliance V Belt applications. V-belt drives are also easy to install, require no lubrication, and dampen shock load.
Here’s the catch: Regular friction drives can both slip 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 befitting the application accessible.
Belt drives are one of the earliest power transmitting systems and were widely used through the Industrial Revolution. After that, flat belts conveyed power over large distances and were made from leather. Later, needs for more powerful machinery, and the growth of large markets like the automobile industry spurred new belt styles. V-belts, with a trapezoidal or V shape, manufactured from rubber, neoprene, and urethane synthetic materials, replaced smooth belts. Now, the improved overall surface area material of modern belts adheres to pulley grooves through friction push, to lessen the tension necessary to transmit torque. The very best portion of the belt, called the strain or insulation section, contains fiber cords for increased strength since it carries the strain of traction push. It helps hold tension members in place and functions as a binder for greater adhesion between cords and additional sections. In this manner, 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 type of drive belt used for power tranny. Their primary function is usually to transmit power from a major source, such as a electric motor, to a second driven unit. They provide the best combination of traction, acceleration transfer, load distribution, and extended service life. Most are limitless and their cross section is definitely trapezoidal or “V” designed. The “V” shape of the belt tracks in a similarly shaped groove on a pulley or sheave. The v-belt wedges in to the groove as the load 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 severe temps. They can be used as friction clutches during set up.
Raw edge type v-belts are more efficient, generate less heat, allow for smaller pulley diameters, enhance power ratings, and offer longer life.
V-belts look like relatively benign and basic devices. Just measure the best 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 you can get.
