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 usually transmitted because of this of the belt’s adherence to the pulley) are an economical option for industrial, automotive, commercial, agricultural, and house 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 slip and creep, resulting in inexact velocity ratios or degraded timing precision between insight and output shafts. For this reason, it is essential to choose a belt appropriate for the application accessible.
Belt drives are among the earliest power transmission systems and were widely used through the Industrial Revolution. Then, flat belts conveyed power over huge distances and were made from leather. Later, demands for better machinery, and the growth of large markets like the automobile market spurred new belt designs. 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 drive, to reduce the tension necessary to transmit torque. The top portion of the belt, known as the tension or insulation section, consists of fiber cords for improved strength as it carries the strain of traction force. It can help hold tension members in place and acts as a binder for greater adhesion between cords and various other 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 fit and structure for reliable, long-long lasting performance.
V-Belts are the most typical kind of drive belt used for power transmitting. Their primary function is definitely to transmit power from a major source, such as a motor, to a second driven unit. They offer the best mixture of traction, quickness transfer, load distribution, and extended service life. The majority are countless and their cross section is usually trapezoidal or “V” formed. The “V” shape of the belt tracks in a similarly designed groove on a pulley or sheave. The v-belt wedges in to the groove as the load improves creating power distribution and torque. V-belts are generally made of rubber or polymer or there may be fibers V Belt embedded for added power and reinforcement.
V-belts are generally within two construction groups: envelope (wrapped) and raw edge.

Wrapped belts have a higher resistance to oils and intense temperatures. They can be utilized as friction clutches during start up.
Raw edge type v-belts are better, 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 best width and circumference, find another belt with the same measurements, and slap it on the drive. There’s only one problem: that approach is about as wrong as possible get.
