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 called friction drives (because power is transmitted as a result of the belt’s adherence to the pulley) are an economical 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: Standard friction drives can both slip and creep, leading to inexact velocity ratios or degraded timing precision between input and output shafts. Because of this, it is essential to select a belt appropriate for the application at hand.
Belt drives are among the earliest power transmitting systems and were trusted through the Industrial Revolution. After that, smooth belts conveyed power over large distances and were created from leather. Later, demands for more powerful machinery, and the growth of large markets like the automobile sector spurred new belt styles. V-belts, with a trapezoidal or V shape, manufactured from rubber, neoprene, and urethane synthetic materials, replaced flat belts. Now, the increased overall surface material of modern belts adheres to pulley grooves through friction power, to lessen the tension required to transmit torque. The very best area of the belt, known as the tension or insulation section, consists of fiber cords for improved strength since it carries the load of traction drive. It helps hold tension members in place and works as a v belt china binder for higher 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 structure for reliable, long-long lasting performance.
V-Belts are the most common type of drive belt used for power tranny. Their primary function is certainly to transmit power from a main source, like a motor, to a secondary driven unit. They offer the best mixture of traction, rate transfer, load distribution, and extended service life. Most are limitless and their cross section can be trapezoidal or “V” formed. The “V” shape of the belt tracks in a similarly 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 commonly manufactured from rubber or polymer or there may be fibers embedded for added strength and reinforcement.
V-belts are generally found in two construction categories: envelope (wrapped) and raw advantage.

Wrapped belts have a higher resistance to oils and severe temps. They can be utilized as friction clutches during set up.
Raw edge type v-belts are better, generate less heat, enable smaller pulley diameters, increase power ratings, and provide longer life.
V-belts appear to be relatively benign and basic devices. Just measure the top width and circumference, find another belt with the same sizes, and slap it on the drive. There’s only 1 problem: that strategy is approximately as wrong as you can get.
