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 called friction drives (because power is 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 slip and creep, resulting in inexact velocity ratios or degraded timing precision between insight and output shafts. Because of this, it is essential to select a belt befitting the application accessible.
Belt drives are one of the earliest power tranny systems and were trusted during the Industrial Revolution. After that, flat belts conveyed power over large distances and were made from leather. Later, demands for better machinery, and the development of large markets like the automobile market spurred new belt styles. V-belts, with a trapezoidal or V shape, manufactured from rubber, neoprene, and urethane synthetic materials, replaced flat belts. Now, the increased overall surface 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, called the tension or insulation section, includes fiber cords for increased strength as it carries the strain of traction drive. It helps hold tension members set up and works as a binder for greater adhesion between cords and additional 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 fit and structure for reliable, long-long lasting performance.
V-Belts are the most common kind of drive belt used for power transmission. Their primary function is to transmit power from a main source, like a electric motor, to a secondary driven unit. They offer the best mixture of traction, rate transfer, load distribution, and extended service life. The majority are countless and their cross section is usually 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 in to 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 within two construction groups: envelope (wrapped) and raw edge.

belts have an increased level of resistance to oils and intense temps. They can be utilized as friction clutches during set up.
Raw edge type v-belts are more efficient, generate less heat, enable smaller pulley diameters, increase power ratings, and provide longer life.
V-belts look like relatively benign and simple devices. Just measure the best width and circumference, find another belt with the same dimensions, and slap it on the drive. There’s only one problem: that strategy is about as wrong as possible get.
