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 definitely 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 easy to install, need no lubrication, and dampen shock load.
Here’s the catch: Regular friction drives may both slide and creep, resulting in inexact velocity ratios or degraded timing precision between insight and output shafts. Because of this, it is essential to choose a belt appropriate for the application at hand.
Belt drives are among the earliest power transmitting systems and were widely used through the Industrial Revolution. After that, flat belts conveyed power over huge distances and were created from leather. Later, needs for better v belt china machinery, and the development 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 flat belts. Now, the increased overall surface material of contemporary belts adheres to pulley grooves through friction power, to lessen the tension necessary to transmit torque. The top section of the belt, called the strain or insulation section, consists of fiber cords for improved strength as it carries the strain of traction power. It can help hold tension members set up and functions as a binder for better adhesion between cords and other 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 fit and structure for reliable, long-lasting performance.
V-Belts are the most typical type of drive belt used for power tranny. Their primary function is to transmit power from a major source, such as a engine, to a second driven unit. They offer the best combination of traction, swiftness transfer, load distribution, and extended service life. Most are endless and their cross section is trapezoidal or “V” shaped. 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 boosts creating power distribution and torque. V-belts are generally made of rubber or polymer or there may be fibers embedded for added power and reinforcement.
V-belts are generally within two construction groups: envelope (wrapped) and raw edge.

Wrapped belts have a higher level of resistance to oils and severe temps. They can be used 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 look like relatively benign and basic devices. Just measure the best width and circumference, discover another belt with the same measurements, and slap it on the drive. There’s only one problem: that strategy is approximately as wrong as possible get.
