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 usually transmitted consequently of the belt’s adherence to the pulley) are a cost-effective option for industrial, automotive, commercial, agricultural, and home 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 slide 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 befitting 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 made from leather. Later, needs for better machinery, and the growth of large markets like the automobile industry 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 v belt china 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 portion of the belt, called the tension or insulation section, contains fiber cords for increased strength since it carries the strain of traction force. It helps hold tension members in place and works as a binder for higher 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 level of resistance with OE quality fit and building for reliable, long-lasting performance.
V-Belts are the most typical kind of drive belt used for power transmitting. Their primary function can be to transmit power from a principal source, just like a electric motor, to a second driven unit. They provide the best mixture of traction, swiftness transfer, load distribution, and extended service life. The majority are countless and their cross section is certainly trapezoidal or “V” designed. The “V” shape of the belt tracks in a likewise shaped groove on a pulley or sheave. The v-belt wedges into the groove as the strain boosts creating power distribution and torque. V-belts are commonly manufactured from rubber or polymer or there could be fibers embedded for added power and reinforcement.
V-belts are generally found in two construction types: envelope (wrapped) and raw advantage.

Wrapped belts have a higher resistance to oils and intense temps. They can be utilized as friction clutches during start up.
Raw edge type v-belts are more efficient, generate less heat, allow for smaller pulley diameters, enhance power ratings, and provide longer life.
V-belts look like relatively benign and simple pieces of equipment. Just measure the top width and circumference, find another belt with the same measurements, and slap it on the drive. There’s only one problem: that strategy is approximately as wrong as you can get.
