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 v belt china 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 simple to install, require no lubrication, and dampen shock load.
Here’s the catch: Standard friction drives may both slip and creep, leading to inexact velocity ratios or degraded timing precision between input and output shafts. For this reason, it is essential to select a belt befitting the application accessible.
Belt drives are among the earliest power transmitting systems and were widely used through the Industrial Revolution. Then, flat belts conveyed power over huge 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 flat belts. Now, the increased overall surface area material of modern belts adheres to pulley grooves through friction pressure, to reduce the tension required to transmit torque. The very best portion of the belt, known as the strain or insulation section, contains fiber cords for increased strength since it carries the strain of traction pressure. It can help hold tension members set up and works as a binder for better adhesion between cords and various other sections. This way, heat build-up is reduced, 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-long lasting 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 primary source, like a electric motor, to a secondary driven unit. They offer the best mixture of traction, speed transfer, load distribution, and extended service life. Most are limitless and their cross section is certainly trapezoidal or “V” formed. The “V” form of the belt tracks in a similarly designed groove on a pulley or sheave. The v-belt wedges into the groove as the strain improves creating power distribution and torque. V-belts are generally made of rubber or polymer or there could be fibers embedded for added strength and reinforcement.
V-belts are generally found in two construction categories: envelope (wrapped) and raw edge.

Wrapped belts have a higher level of resistance to oils and intense temperatures. They can be utilized as friction clutches during set up.
Raw edge type v-belts are more efficient, generate less heat, allow for smaller pulley diameters, increase power ratings, and offer longer life.
V-belts look like 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 one problem: that approach is approximately as wrong as you can get.
