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 because of this of the belt’s adherence to the pulley) are an economical option for industrial, auto, commercial, agricultural, and house appliance applications. V-belt drives are also simple to install, need no lubrication, and dampen shock load.
Here’s the catch: Standard friction drives can both slip and creep, resulting in inexact velocity ratios or degraded timing precision between input and output shafts. For this reason, it is important to select a belt befitting the application at hand.
Belt drives are one of the earliest power transmission systems and were widely used during the Industrial V Belt Revolution. Then, toned belts conveyed power over large distances and were created from leather. Later, needs 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, 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 reduce the tension necessary to transmit torque. The very best section of the belt, called the tension or insulation section, contains fiber cords for increased strength since it carries the load of traction push. It helps hold tension members set up and functions as a binder for greater adhesion between cords and additional 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 suit and construction for reliable, long-enduring performance.
V-Belts are the most typical kind of drive belt used for power transmitting. Their primary function is usually to transmit power from a main source, such as a electric motor, to a secondary driven unit. They offer the best mixture of traction, speed transfer, load distribution, and extended service life. The majority are unlimited and their cross section can be trapezoidal or “V” designed. The “V” form of the belt tracks in a likewise shaped groove on a pulley or sheave. The v-belt wedges into the groove as the strain increases creating power distribution and torque. V-belts are commonly made of rubber or polymer or there might be fibers embedded for added power and reinforcement.
V-belts are generally within two construction classes: envelope (wrapped) and raw edge.

Wrapped belts have a higher resistance to oils and intense temperature ranges. They can be utilized as friction clutches during start up.
Raw edge type v-belts are more efficient, generate less heat, allow for smaller pulley diameters, increase power ratings, and offer longer life.
V-belts appear to be relatively benign and basic pieces of equipment. Just measure the top width and circumference, find another belt with the same dimensions, and slap it on the drive. There’s only one problem: that strategy is approximately as wrong as possible get.
