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 definitely transmitted because of this of the belt’s adherence to the pulley) are a cost-effective 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: Regular friction drives can both slip and creep, leading to inexact velocity ratios or degraded timing precision between input and output shafts. Because of this, it is important to select a belt befitting the application accessible.
Belt drives are among the earliest power tranny systems and were trusted through the Industrial Revolution. Then, smooth 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 industry spurred new belt designs. V-belts, with a trapezoidal or V shape, made of rubber, neoprene, and urethane synthetic materials, replaced smooth belts. Now, the increased overall surface area material of modern belts adheres to pulley grooves through friction power, to reduce the V Belt tension required to transmit torque. The top part of the belt, known as the strain or insulation section, includes fiber cords for improved strength since it carries the strain of traction push. It can help hold tension members in place and functions as a binder for higher adhesion between cords and various other sections. This way, heat build-up is decreased, extending belt life.
We’ve designed our V-belts for wear, corrosion, and heat level of resistance with OE quality fit and building for reliable, long-enduring performance.
V-Belts are the most common kind of drive belt used for power transmitting. Their primary function is to transmit power from a major source, such as a motor, to a secondary driven unit. They offer the best mixture of traction, swiftness transfer, load distribution, and extended service life. Most are countless and their cross section is usually trapezoidal or “V” formed. The “V” form of the belt tracks in a likewise designed groove on a pulley or sheave. The v-belt wedges in to the groove as the strain increases creating power distribution and torque. V-belts are generally 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 advantage.

Wrapped belts have an increased resistance to oils and extreme temps. They can be used as friction clutches during start up.
Raw edge type v-belts are more efficient, generate less heat, enable smaller pulley diameters, increase power ratings, and provide longer life.
V-belts look like relatively benign and simple devices. Just measure the best 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 you can get.
