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 known as friction drives (because power is transmitted consequently 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 simple to install, need no lubrication, and dampen shock load.
Here’s the catch: Standard friction drives can both slip and creep, resulting in inexact velocity ratios or degraded timing precision between insight and output shafts. Because of this, it is important to choose a belt befitting the application at hand.
Belt drives are one of 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, needs for more powerful machinery, and the development of large markets like the automobile market spurred new belt designs. V-belts, with a trapezoidal or V shape, manufactured from rubber, neoprene, and urethane synthetic materials, replaced toned belts. Now, the improved overall surface material of modern belts adheres to pulley grooves through friction push, to lessen the tension required to transmit torque. The top part of the belt, called the strain or insulation section, includes fiber cords for increased strength as it carries the load of traction power. It can help hold tension members in place and acts as a binder for better adhesion between cords and other 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 suit and construction for reliable, long-lasting 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 principal source, just like a electric motor, to a second driven unit. They provide the best combination of traction, speed transfer, load distribution, and extended service life. The majority are limitless and their cross section can be trapezoidal or “V” formed. The “V” shape of the belt tracks in a likewise shaped v belt china groove on a pulley or sheave. The v-belt wedges into the groove as the strain increases creating power distribution and torque. V-belts are commonly made of rubber or polymer or there could be fibers embedded for added strength and reinforcement.
V-belts are generally within two construction classes: envelope (wrapped) and raw edge.

Wrapped belts have a higher level of resistance to oils and extreme temperatures. They can be used as friction clutches during set up.
Raw edge type v-belts are more efficient, generate less heat, allow for smaller pulley diameters, boost power ratings, and provide longer life.
V-belts appear to be relatively benign and simple devices. Just measure the top width and circumference, discover another belt with the same measurements, and slap it on the drive. There’s only 1 problem: that approach is approximately as wrong as possible get.
