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 certainly transmitted as a result of the belt’s adherence to the pulley) are an economical option for industrial, auto, 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, resulting in inexact V Belt velocity ratios or degraded timing precision between insight and output shafts. Because of this, it is important to select a belt befitting the application at hand.
Belt drives are among the earliest power tranny systems and were widely used during the Industrial Revolution. Then, flat belts conveyed power over large distances and were made from leather. Later, demands for better machinery, and the growth of large markets like the automobile industry spurred new belt styles. V-belts, with a trapezoidal or V shape, made of rubber, neoprene, and urethane synthetic materials, replaced toned belts. Now, the increased overall surface material of modern belts adheres to pulley grooves through friction push, to reduce the tension necessary to transmit torque. The very best part of the belt, called the tension or insulation 
section, consists of fiber cords for improved strength since it carries the load of traction push. It helps hold tension members in place and functions as a binder for better adhesion between cords and additional sections. In this manner, heat build-up is reduced, extending belt life.
We’ve designed our V-belts for wear, corrosion, and heat resistance with OE quality fit and construction for reliable, long-long lasting performance.
V-Belts are the most typical type of drive belt used for power tranny. Their primary function is certainly to transmit power from a principal source, like a motor, to a secondary driven unit. They offer the best combination of traction, quickness transfer, load distribution, and extended service life. The majority are unlimited and their cross section is 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 into the groove as the load increases 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 within two construction types: envelope (wrapped) and raw edge.
Wrapped belts have a higher resistance to oils and extreme temperatures. They can be used as friction clutches during set up.
Raw edge type v-belts are better, generate less heat, enable smaller pulley diameters, boost 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 measurements, and slap it on the drive. There’s only 1 problem: that strategy is approximately as wrong as you can get.
