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 certainly transmitted as a result of the belt’s adherence to the pulley) are an economical option for industrial, auto, 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: Regular friction drives may both slip and creep, resulting in inexact velocity ratios or degraded timing precision between input and output shafts. For this reason, it is important to select a belt befitting the application accessible.
Belt drives are among the earliest power tranny systems and were widely used during the Industrial v belt china Revolution. Then, toned belts conveyed power over huge distances and were created from leather. Later, needs for more powerful machinery, and the development of large markets like the automobile industry 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 increased overall surface area material of modern belts adheres to pulley grooves through friction force, to lessen the tension required to transmit torque. The very best section of the belt, called the strain or insulation section, consists of fiber cords for improved strength since it carries the strain of traction drive. It helps hold tension members set up and acts as a binder for greater 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 fit and structure for reliable, long-lasting performance.
V-Belts are the most typical kind of drive belt used for power transmission. Their primary function is to transmit power from a major source, like a motor, to a secondary driven unit. They provide the best mixture of traction, quickness transfer, load distribution, and extended service life. The majority are countless and their cross section is trapezoidal or “V” formed. The “V” form of the belt tracks in a likewise formed groove on a pulley or sheave. The v-belt wedges in to the groove as the strain improves creating power distribution and torque. V-belts are generally made of rubber or polymer or there could be fibers embedded for added strength and reinforcement.
V-belts are generally within two construction groups: envelope (wrapped) and raw edge.
Wrapped belts have a higher level of resistance to oils and intense temperature ranges. They can be used 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 top width and circumference, find another belt with the same measurements, and slap it on the drive. There’s only one problem: that strategy is about as wrong as possible get.
