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 definitely transmitted because of this 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, require no lubrication, and dampen shock load.
Here’s the catch: Standard friction drives can both slide 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 befitting the application accessible.
Belt drives are one of the earliest power tranny systems and were trusted through the Industrial Revolution. After that, smooth belts conveyed power over large 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 styles. V-belts, with a trapezoidal or V shape, manufactured from rubber, neoprene, and urethane v belt china synthetic materials, replaced smooth belts. Now, the increased overall surface material of contemporary belts adheres to pulley grooves through friction pressure, to reduce the tension required to transmit torque. The very best section of the belt, called the strain or insulation section, consists of fiber cords for increased strength as it carries the strain of traction pressure. It can help hold tension members set up and functions 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 level of resistance with OE quality suit and building for reliable, long-enduring performance.
V-Belts are the most common type of drive belt used for power transmitting. Their primary function is certainly to transmit power from a primary source, such as a motor, to a second driven unit. They provide the best mixture of traction, swiftness transfer, load distribution, and extended service life. The majority are limitless and their cross section is usually trapezoidal or “V” designed. The “V” form 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 increases creating power distribution and torque. V-belts are commonly manufactured from rubber or polymer or there might be fibers embedded for added power and reinforcement.
V-belts are generally found in two construction categories: envelope (wrapped) and raw advantage.

Wrapped belts have an increased level of resistance to oils and extreme temps. 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 offer longer life.
V-belts look like 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 1 problem: that approach is approximately as wrong as you can get.
