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 as a result of the belt’s adherence to the pulley) are a cost-effective option for industrial, automotive, commercial, agricultural, and house appliance applications. V-belt drives are also simple to install, require no lubrication, and dampen shock load.
Here’s the catch: Standard friction drives may 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 select 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, smooth belts conveyed power over huge distances and were made from leather. Later, needs for more powerful machinery, and the growth of large markets such as the automobile market spurred new belt designs. V-belts, with a trapezoidal or V shape, manufactured from rubber, neoprene, and urethane synthetic materials, replaced smooth belts. Now, the improved overall surface area material of contemporary belts adheres to pulley grooves through friction force, to reduce the tension v belt china required to transmit torque. The very best portion of the belt, called the tension or insulation section, contains fiber cords for improved strength since it carries the strain of traction power. It helps hold tension members in place and acts as a binder for better adhesion between cords and additional sections. This way, 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 construction for reliable, long-enduring performance.
V-Belts are the most typical type of drive belt used for power transmission. Their primary function is definitely to transmit power from a major source, just like a engine, to a second driven unit. They offer the best combination of traction, swiftness transfer, load distribution, and extended service life. The majority are limitless and their cross section is certainly trapezoidal or “V” designed. The “V” form of the belt tracks in a likewise designed groove on a pulley or sheave. The v-belt wedges in to the 
V-belts are generally within two construction groups: envelope (wrapped) and raw advantage.
Wrapped belts have an increased level of resistance to oils and severe 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 simple pieces of equipment. Just measure the best width and circumference, find another belt with the same dimensions, and slap it on the drive. There’s only one problem: that approach is about as wrong as you can get.
