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 certainly transmitted as a result of the belt’s adherence to the pulley) are a cost-effective option for industrial, auto, 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: Regular friction drives can both slide and creep, resulting in inexact velocity ratios or degraded timing precision between input and output shafts. For this reason, it is essential to select a belt befitting the application at hand.
Belt drives are among the earliest power transmitting systems and were trusted during the Industrial Revolution. Then, smooth belts conveyed power over huge 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 designs. V-belts, with a trapezoidal or V shape, manufactured from rubber, neoprene, and urethane synthetic materials, replaced flat belts. Now, the improved overall surface area material of modern belts adheres to pulley grooves through friction push, to lessen the v belt china tension necessary to transmit torque. The very best section of the belt, called the tension or insulation section, includes fiber cords for increased strength as it carries the load of traction push. It can help hold tension members in place and works as a binder for greater adhesion between cords and other sections. This way, heat build-up is reduced, extending belt life.
We’ve designed our V-belts for wear, corrosion, and heat resistance with OE quality suit and building for reliable, long-enduring performance.
V-Belts are the most typical kind of drive belt used for power tranny. Their primary function can be to transmit power from a main source, like a engine, to a secondary driven unit. They provide the best mixture of traction, velocity transfer, load distribution, and extended service life. The majority are limitless and their cross section is usually 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 strain increases creating power distribution and torque. V-belts are generally made of rubber or polymer or there could 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 a higher resistance to oils and extreme temperature ranges. They can be utilized as friction clutches during set up.
Raw edge type v-belts are more efficient, generate less heat, allow for smaller pulley diameters, enhance 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 dimensions, and slap it on the drive. There’s only 1 problem: that strategy is about as wrong as you can get.
