The most common 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 as a result 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, need no lubrication, and dampen shock load.
Here’s the catch: Regular friction drives may both slip and creep, leading to inexact velocity ratios or degraded timing precision between insight and output shafts. For this reason, it is essential to choose a belt befitting the application at hand.
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 created from leather. Later, demands for more powerful machinery, and the growth 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 smooth belts. Now, the improved overall surface material of contemporary belts adheres to pulley grooves V Belt through friction pressure, to lessen the tension required to transmit torque. The top part of the belt, known as the strain or insulation section, contains fiber cords for increased strength since it carries the load of traction push. It can help hold tension members set up and works as a binder for greater adhesion between cords and other sections. In this manner, 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 structure for reliable, long-enduring performance.
V-Belts are the most typical type of drive belt used for power tranny. Their primary function can be to transmit power from a principal source, such as a engine, to a secondary driven unit. They provide the best combination of traction, velocity transfer, load distribution, and extended service life. Most are countless 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 load increases creating power distribution and torque. V-belts are generally made of rubber or polymer or there could 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 a higher level of resistance to oils and extreme temperatures. They can be used as friction clutches during start 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 simple devices. Just measure the best width and circumference, find another belt with the same sizes, and slap it on the drive. There’s only one problem: that strategy is approximately as wrong as possible get.
