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, automotive, 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 slide and creep, leading to inexact velocity ratios or degraded timing precision between input and output shafts. Because of this, it is essential to choose a belt befitting the application at hand.
Belt drives are among the earliest power tranny systems and were trusted through the Industrial Revolution. Then, flat belts conveyed power over large distances and were created from leather. Later, demands for more powerful machinery, and the growth 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 flat belts. Now, the increased overall surface area material of modern belts adheres to pulley grooves through friction push, to lessen the tension required to transmit torque. The top area of the belt, known as the tension or insulation section, consists of fiber cords for increased strength as it carries the strain of traction power. It helps hold tension members set up and works as a binder for higher 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 match and building for reliable, long-long lasting performance.
V-Belts are the most common kind of drive belt used for power tranny. Their primary function is certainly to transmit power from a principal source, such as a motor, to a secondary driven unit. They offer the best mixture of traction, quickness transfer, load distribution, and extended service life. Most are limitless and their cross section is usually trapezoidal or “V” designed. The “V” shape of the belt tracks in a likewise designed groove on a pulley or sheave. The v-belt wedges into the groove as the load increases creating power distribution and torque. V-belts are generally manufactured from rubber or polymer or there might be fibers embedded for added power and v belt china reinforcement.
V-belts are generally within two construction groups: envelope (wrapped) and raw advantage.
Wrapped belts have a higher level of resistance to oils and severe temps. They can be utilized as friction clutches during start up.
Raw edge type v-belts are better, generate less heat, enable smaller pulley diameters, increase power ratings, and provide longer life.
V-belts look like relatively benign and basic 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 approach 
is approximately as wrong as possible get.
