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 known as friction drives (because power is transmitted because of this of the belt’s adherence to the pulley) are an v belt china economical option for industrial, auto, commercial, agricultural, and home appliance applications. V-belt drives are also easy 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. For this reason, it is essential to choose a belt appropriate for the application at hand.
Belt drives are among the earliest power transmission systems and were widely used through the Industrial Revolution. Then, toned belts conveyed power over huge distances and were created from leather. Later, needs for better machinery, and the development 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 toned belts. Now, the increased overall surface area material of contemporary belts adheres to pulley grooves through friction power, to reduce the tension necessary to transmit torque. The top section of the belt, called the strain or insulation section, contains fiber cords for increased strength since it carries the load of traction pressure. It can help hold tension members set up and works 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 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 transmitting. Their primary function is certainly to transmit power from a principal source, like a motor, to a second driven unit. They provide the best combination of traction, acceleration transfer, load distribution, and extended service life. Most are unlimited and their cross section is trapezoidal or “V” shaped. The “V” shape of the belt tracks in a similarly designed groove on a pulley or sheave. The v-belt wedges into the groove as the strain raises creating power distribution and torque. V-belts are generally made of rubber or polymer or there might be fibers embedded for added power and reinforcement.
V-belts are generally within two construction classes: envelope (wrapped) and raw edge.
Wrapped belts have a higher level of resistance to oils and intense temps. They can be used as friction clutches during set up.
Raw edge type v-belts are better, generate less heat, allow for smaller pulley diameters, boost 
power ratings, and provide 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 dimensions, and slap it on the drive. There’s only 1 problem: that approach is about as wrong as you can get.
