v belt

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 transmitted because of this of the belt’s adherence to the pulley) are a cost-effective option for industrial, automotive, 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: Regular friction drives can both slide and creep, resulting in inexact velocity ratios or degraded timing precision between input and output shafts. For this reason, it is essential to V Belt choose a belt appropriate for the application at hand.
Belt drives are among the earliest power transmission systems and were trusted through the Industrial Revolution. After that, toned belts conveyed power over large distances and were made from leather. Later, needs for better machinery, and the development of large markets such as the automobile sector spurred new belt designs. V-belts, with a trapezoidal or V shape, manufactured from rubber, neoprene, and urethane synthetic materials, replaced flat belts. Now, the increased overall surface area material of contemporary belts adheres to pulley grooves through friction power, to reduce the tension required to transmit torque. The top section of the belt, called the tension or insulation section, includes fiber cords for increased strength since it carries the load of traction drive. It helps hold tension members in place and acts as a binder for greater adhesion between cords and additional sections. In this manner, heat build-up is decreased, extending belt life.
We’ve designed our V-belts for wear, corrosion, and heat resistance with OE quality match and construction for reliable, long-enduring performance.
V-Belts are the most common type of drive belt used for power tranny. Their primary function can be to transmit power from a main source, just like a motor, to a second driven unit. They provide the best mixture of traction, speed transfer, load distribution, and extended service life. Most are countless and their cross section is usually trapezoidal or “V” shaped. The “V” shape of the belt tracks in a likewise 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 commonly manufactured from rubber or polymer or there might be fibers embedded for added power and reinforcement.
V-belts are generally within two construction types: envelope (wrapped) and raw edge.

Wrapped belts have an increased level of resistance to oils and extreme temperatures. 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 look like relatively benign and basic 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 strategy is approximately as wrong as possible get.
