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 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 easy to install, need no lubrication, and dampen shock load.
Here’s the catch: Standard friction drives can both slide and creep, resulting in inexact velocity ratios or degraded timing precision between insight and output shafts. For this reason, it is important to choose a belt appropriate for the application accessible.
Belt drives are among the earliest power transmitting systems and were trusted 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 development of large markets such as the automobile sector spurred new belt designs. V-belts, with a trapezoidal or V shape, manufactured from rubber, neoprene, and urethane synthetic materials, replaced smooth belts. Now, the increased overall surface material of V Belt contemporary belts adheres to pulley grooves through friction force, to reduce the tension required to transmit torque. The top portion of the belt, known as the strain or insulation section, includes fiber cords for increased strength as it carries the strain of traction power. It helps hold tension members set up and functions as a binder for better 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 resistance with OE quality match and building for reliable, long-lasting performance.
V-Belts are the most typical kind of drive belt used for power transmission. Their primary function can be to transmit power from a principal source, like a motor, to a second driven unit. They provide the best combination of traction, acceleration transfer, load distribution, and extended service life. Most are endless and their cross section is definitely trapezoidal or “V” designed. The “V” shape of the belt tracks in a likewise formed 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 manufactured from rubber or polymer or there may be fibers embedded for added power and reinforcement.
V-belts are generally found in two construction categories: envelope (wrapped) and raw edge.

Wrapped belts have a higher resistance to oils and intense temps. They can be used as friction clutches during set up.
Raw edge type v-belts are better, generate less heat, allow for smaller pulley diameters, boost power ratings, and provide longer life.
V-belts appear to be relatively benign and simple devices. 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.
