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 certainly transmitted consequently of the belt's adherence to the pulley) are a cost-effective 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: Regular friction drives can both slip and creep, resulting in inexact velocity ratios or degraded timing precision between input and output shafts. For this reason, it is essential to select a belt appropriate for the application accessible.
Belt drives are one of the earliest power transmission systems and were widely used during 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 such as the automobile sector spurred new belt designs. V-belts, with a trapezoidal or V shape, made of rubber, neoprene, and urethane synthetic materials, replaced smooth belts. Now, the improved overall surface material of modern belts adheres to pulley grooves through friction drive, to lessen the tension required to transmit torque. The very best portion of the belt, called the strain or insulation section, consists of fiber cords for improved strength as it carries the strain of V Belt traction pressure. It helps hold tension members in place and works as a binder for higher adhesion between cords and various other sections. In this manner, heat build-up is decreased, extending belt life.
We’ve designed our V-belts for wear, corrosion, and heat level of resistance with OE quality suit and structure for reliable, long-lasting performance.
V-Belts are the most typical kind of drive belt used for power transmitting. Their primary function is certainly to transmit power from a main source, like a electric motor, to a second driven unit. They provide the best mixture of traction, quickness transfer, load distribution, and extended service life. Most are countless and their cross section is definitely trapezoidal or “V” formed. 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 boosts creating power distribution and torque. V-belts are generally made of rubber or polymer or there may be fibers embedded for added power and reinforcement.
V-belts are generally found in two construction groups: envelope (wrapped) and raw edge.

Wrapped belts have an increased 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, 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 best width and circumference, find 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.
