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 an economical option for industrial, auto, commercial, agricultural, and house 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, leading to 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 accessible.
Belt drives are among the earliest power transmission systems and were trusted through the Industrial Revolution. Then, flat belts V Belt conveyed power over huge 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 toned belts. Now, the increased overall surface area material of modern belts adheres to pulley grooves through friction power, to lessen the tension necessary to transmit torque. The top portion of the belt, called the strain or insulation section, contains fiber cords for increased strength as it carries the load of traction power. It helps hold tension members in place and acts as a binder for higher 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 resistance with OE quality fit and construction for reliable, long-enduring performance.
V-Belts are the most typical type of drive belt used for power transmission. Their primary function is certainly to transmit power from a principal source, such as a motor, to a second driven unit. They offer the best combination of traction, rate transfer, load distribution, and extended service life. The majority are countless and their cross section is trapezoidal or “V” designed. The “V” shape of the belt tracks in a likewise formed groove on a pulley or sheave. The v-belt wedges in to the groove as the load raises creating power distribution and torque. V-belts are commonly manufactured from rubber or polymer or there may be fibers embedded for added strength 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 intense temps. They can be utilized as friction clutches during set up.
Raw edge type v-belts are better, generate less heat, allow for smaller pulley diameters, increase power ratings, and provide longer life.
V-belts appear to be relatively benign and simple pieces of equipment. Just measure the best width and circumference, discover another belt with the same sizes, and slap it on the drive. There’s only one problem: that strategy is about as wrong as you can get.
