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 certainly transmitted because of this 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 simple to install, need no lubrication, and dampen shock load.
Here’s the catch: Standard friction drives can both slide and creep, resulting in inexact velocity ratios or degraded timing precision between input and output shafts. Because of this, it is important to choose a belt appropriate for the application at hand.
Belt drives are among the earliest power transmitting systems and were trusted through the Industrial Revolution. After that, toned belts conveyed power over large distances and were created from leather. Later, demands for more powerful machinery, and the growth of large markets such as the automobile market spurred new belt styles. V-belts, with a trapezoidal or V shape, made of rubber, neoprene, and urethane synthetic materials, replaced flat belts. Now, the increased overall surface area material of modern belts adheres to v belt china pulley grooves through friction force, to reduce the tension necessary to transmit torque. The top section of the belt, called the tension or insulation section, includes fiber cords for improved strength since it carries the strain of traction force. It can help hold tension members set up and works as a binder for greater 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 suit and structure for reliable, long-lasting performance.
V-Belts are the most typical type of drive belt used for power transmission. Their primary function can be to transmit power from a principal source, like a electric motor, to a second driven unit. They provide the best combination of traction, swiftness transfer, load distribution, and extended service life. The majority are unlimited and their cross section is definitely 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 in to the groove as the strain boosts creating power distribution and torque. V-belts are generally made of rubber or polymer or there could be fibers embedded for added power and reinforcement.
V-belts are generally within two construction categories: 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 set up.
Raw edge type v-belts are more efficient, generate less heat, allow for smaller pulley diameters, boost power ratings, and offer longer life.
V-belts look like relatively benign and simple pieces of equipment. Just measure the top 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.
