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 usually transmitted consequently of the belt’s adherence to the pulley) are an economical option for industrial, automotive, 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: Standard friction drives can both slip and creep, resulting in inexact velocity ratios or degraded timing precision between input and output shafts. Because of this, it is important to choose a belt befitting the application at hand.
Belt drives are one of the earliest power transmitting systems and were widely used during the Industrial Revolution. After that, toned 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 sector spurred new belt designs. V-belts, with a trapezoidal or V shape, made of rubber, neoprene, and urethane synthetic materials, replaced smooth belts. Now, the increased overall surface material of contemporary belts adheres to pulley grooves through friction pressure, to reduce the tension required to transmit V Belt torque. The very best area of the belt, called the tension or insulation section, includes fiber cords for improved strength since it carries the strain of traction pressure. It can help hold tension members set up and works as a binder for better adhesion between cords and additional sections. In this manner, 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 match and structure for reliable, long-long lasting performance.
V-Belts are the most common kind of drive belt used for power tranny. Their primary function can be to transmit power from a major source, such as a electric motor, to a secondary driven unit. They provide the best mixture of traction, speed transfer, load distribution, and extended service life. Most are limitless 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 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 within two construction types: envelope (wrapped) and raw advantage.

Wrapped belts have an increased level of resistance to oils and extreme temperatures. They can be used as friction clutches during start up.
Raw edge type v-belts are more efficient, generate less heat, enable smaller pulley diameters, enhance power ratings, and offer longer life.
V-belts look like relatively benign and basic devices. Just measure the top width and circumference, find another belt with the same dimensions, and slap it on the drive. There’s only 1 problem: that approach is about as wrong as possible get.
