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 is transmitted as a result 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, need no lubrication, and dampen shock load.
Here’s the catch: Standard friction drives may both slide and creep, resulting in inexact velocity ratios or degraded timing precision between insight and output shafts. For this reason, it is essential to select a belt appropriate for the application at hand.
Belt drives are one of the earliest power transmission systems and were widely used during the Industrial Revolution. After that, smooth belts conveyed power over huge v belt china distances and were created from leather. Later, needs for better machinery, and the growth of large markets such as the automobile sector spurred new belt styles. V-belts, with a trapezoidal or V shape, manufactured from rubber, neoprene, and urethane synthetic materials, replaced smooth belts. Now, the improved overall surface area material of contemporary belts adheres to pulley grooves through friction push, to lessen the tension necessary to transmit torque. The top portion of the belt, known as the tension or insulation section, consists of fiber cords for increased strength since it carries the load of traction force. It helps hold tension members set up and functions as a binder for greater adhesion between cords and additional sections. In this manner, heat build-up is reduced, extending belt life.
We’ve designed our V-belts for wear, corrosion, and heat resistance with OE quality suit and building for reliable, long-long lasting performance.
V-Belts are the most typical kind of drive belt used for power tranny. Their primary function can be to transmit power from a major source, just like a engine, to a second driven unit. They offer the best mixture of traction, velocity transfer, load distribution, and extended service life. Most are unlimited and their cross section is certainly trapezoidal or “V” shaped. The “V” shape of the belt tracks in a similarly formed groove on a pulley or sheave. The v-belt wedges into the groove as the load improves 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 categories: envelope (wrapped) and raw advantage.

Wrapped belts have a higher level of resistance to oils and severe 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 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 one problem: that approach is approximately as wrong as possible get.
