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 called friction drives (because power is definitely transmitted consequently of the belt’s adherence to the pulley) are a cost-effective option for industrial, automotive, commercial, agricultural, and house appliance applications. V-belt drives are also easy to install, require no lubrication, and dampen shock load.
Here’s the catch: Regular friction drives can both slip and creep, leading to inexact velocity ratios or degraded timing precision between input and output shafts. For this reason, it is essential to choose a belt appropriate for the application accessible.
Belt drives are one of the earliest power transmission systems and were trusted during the Industrial Revolution. Then, smooth 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 market 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 area material of modern belts adheres to pulley grooves through friction drive, to lessen the tension required to transmit torque. The top area of the belt, called the strain or insulation section, contains fiber cords for improved strength as it carries the strain of traction force. It can help hold tension members in place and acts as a binder for greater adhesion between cords and other 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 structure for reliable, long-enduring performance.
V-Belts are the most typical kind of drive belt used for power transmission. Their primary function is definitely to transmit power from a main source, such as a electric motor, to a second driven unit. They offer the best combination of traction, acceleration transfer, load distribution, and extended service life. Most are endless and their cross section can be 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 into the groove as the load boosts creating power distribution and torque. V-belts are generally made of rubber or polymer or there might be fibers embedded for added power and reinforcement.
V-belts are generally found in two construction groups: envelope (wrapped) and raw advantage.

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