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 usually transmitted as a result of the belt’s adherence to the pulley) are a cost-effective option for industrial, auto, commercial, agricultural, and home appliance applications. V-belt drives are also simple to install, require no lubrication, and dampen shock load.
Here’s the catch: Regular friction drives can both slide and creep, resulting in inexact velocity ratios or degraded timing precision between insight and output shafts. Because of this, it is essential to select a belt befitting the application at hand.
Belt drives are among the earliest power transmission systems and were widely used during the Industrial Revolution. Then, smooth belts conveyed power over huge distances and were made from leather. Later, demands for more powerful machinery, and the development of large markets like the automobile industry spurred new belt designs. V-belts, with a trapezoidal or V shape, manufactured from rubber, neoprene, and urethane synthetic materials, replaced toned belts. Now, the increased overall surface material of modern belts adheres to pulley grooves through friction drive, to lessen the tension necessary to transmit torque. The very best portion of the belt, known as the strain or insulation section, includes fiber cords for increased strength since it carries the strain of traction drive. It can help hold tension members set up and works as a binder for greater adhesion between cords and various other sections. In this manner, heat build-up is reduced, extending belt life.
We’ve designed our V-belts for wear, corrosion, and heat level of resistance with OE quality suit and construction for reliable, long-long lasting performance.
V-Belts are the most typical type of drive belt used for power transmission. Their primary function is certainly to transmit power from a principal source, just like a engine, to a secondary driven unit. They provide the best mixture of traction, speed transfer, load distribution, and extended service life. Most are endless and their cross V Belt section is definitely trapezoidal or “V” designed. The “V” shape of the belt tracks in a likewise designed groove on a pulley or sheave. The v-belt wedges in to the groove as the load increases creating power distribution and torque. V-belts are commonly made of rubber or polymer or there might 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 a higher level of resistance to oils and severe 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 look like relatively benign and simple pieces of equipment. Just measure the top width and circumference, find another belt with the same measurements, and slap it on the drive. There’s only one problem: that approach is about as wrong as possible get.
