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 usually transmitted because of this 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, need no lubrication, and dampen shock load.
Here’s the catch: Regular friction drives may both slip and creep, leading to inexact velocity ratios or degraded timing precision between insight and output shafts. Because of this, it is important to select a belt befitting the application at hand.
Belt drives are among the earliest power tranny systems and were widely used through the Industrial Revolution. After that, flat belts conveyed power over huge distances and were created from leather. Later, demands for more powerful machinery, and the development of large markets such as the automobile sector spurred new belt styles. V-belts, with a trapezoidal or V shape, made of rubber, neoprene, and urethane synthetic materials, replaced smooth belts. Now, the improved overall surface material of contemporary belts adheres to pulley grooves through friction force, to lessen the tension necessary to transmit torque. The top portion of the belt, called the strain or v belt china insulation section, contains fiber cords for increased strength since it carries the load of traction push. It helps hold tension members in place and functions as a binder for better 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 level of resistance with OE quality suit and structure for reliable, long-enduring performance.
V-Belts are the most common type of drive belt used for power tranny. Their primary function is definitely to transmit power from a principal source, just like a motor, to a secondary driven unit. They provide the best combination of traction, rate transfer, load distribution, and extended service life. The majority are countless and their cross section is 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 increases creating power distribution and torque. V-belts are generally manufactured from rubber or polymer or there could be fibers embedded for added power and reinforcement.
V-belts are generally found in two construction categories: envelope (wrapped) and raw advantage.

Wrapped belts have a higher level of resistance to oils and severe temperatures. They can be used as friction clutches during start up.
Raw edge type v-belts are better, generate less heat, enable smaller pulley diameters, enhance power ratings, and offer longer life.
V-belts appear to be relatively benign and simple 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 strategy is approximately as wrong as possible get.
