v belt

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 house appliance applications. V-belt drives are also easy to install, require no lubrication, and dampen shock load.
Here’s the catch: Regular friction drives can both slip and creep, leading to inexact velocity ratios or degraded timing precision between input and output shafts. Because of this, it is important to select a belt befitting the application accessible.
Belt drives are among the earliest power tranny systems and were trusted through the Industrial Revolution. Then, toned belts conveyed power over large distances and were made from leather. Later, demands for more powerful machinery, and the growth of large markets like the automobile industry 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 V Belt increased overall surface material of modern belts adheres to pulley grooves through friction power, to reduce the tension required to transmit torque. The top part of the belt, known as the strain or insulation section, includes fiber cords for improved strength as it carries the strain of traction push. It can help hold tension members in place and functions as a binder for higher adhesion between cords and various other sections. This way, 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 building for reliable, long-enduring performance.
V-Belts are the most common kind of drive belt used for power transmitting. Their primary function is usually to transmit power from a principal source, such as a motor, to a secondary driven unit. They offer the best combination of traction, swiftness transfer, load distribution, and extended service life. Most are endless and their cross section is definitely trapezoidal or “V” formed. The “V” form of the belt tracks in a likewise designed groove on a pulley or sheave. The v-belt wedges in to the groove as the strain increases creating power distribution and torque. V-belts are generally manufactured from rubber or polymer or there could be fibers embedded for added strength and reinforcement.
V-belts are generally found in two construction classes: envelope (wrapped) and raw edge.

Wrapped belts have an increased resistance to oils and extreme temps. They can be used as friction clutches during start up.
Raw edge type v-belts are better, generate less heat, enable smaller pulley diameters, boost power ratings, and provide longer life.
V-belts look like relatively benign and simple devices. Just measure the best width and circumference, find another belt with the same sizes, and slap it on the drive. There’s only 1 problem: that strategy is about as wrong as you can get.
