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 can be transmitted consequently of the belt’s adherence to the pulley) are a cost-effective option for industrial, automotive, commercial, v belt china 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 input and output shafts. Because of this, it is important to select a belt appropriate for the application accessible.
Belt drives are among the earliest power transmitting systems and were widely used during the Industrial Revolution. After that, toned belts conveyed power over huge distances and were made from leather. Later, demands for better machinery, and the growth of large markets like the automobile market 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 modern belts adheres to pulley grooves through friction drive, to lessen the tension necessary to transmit torque. The top area of the belt, known as the strain or insulation section, contains fiber cords for increased strength since it carries the load of traction power. It can help hold tension members in place and works 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 resistance with OE quality match and structure for reliable, long-lasting performance.
V-Belts are the most typical kind of drive belt used for power transmission. Their primary function is definitely to transmit power from a major source, like a electric motor, to a secondary driven unit. They offer the best mixture of traction, rate transfer, load distribution, and extended service life. The majority are endless and their cross section is certainly trapezoidal or “V” shaped. The “V” shape of the belt tracks in a likewise shaped groove on a pulley or sheave. The v-belt wedges in to the groove as the load raises creating power distribution and torque. V-belts are generally manufactured from rubber or polymer or there may be fibers embedded for added power and reinforcement.
V-belts are generally found in two construction classes: envelope (wrapped) and raw edge.

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