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 transmitted consequently of the belt’s adherence to the pulley) are a cost-effective 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: Standard friction drives can both slip and creep, leading to inexact velocity ratios or degraded timing precision between input and output shafts. For this reason, it is essential to select a belt appropriate for the application at hand.
Belt drives are one of the earliest power tranny systems and were widely used through the Industrial Revolution. Then, toned belts conveyed power over huge distances and were made from leather. Later, demands for better machinery, and the growth of large markets such as the automobile market spurred new belt styles. V-belts, with a trapezoidal or V shape, made of rubber, neoprene, and urethane synthetic materials, replaced smooth belts. Now, the improved overall surface area material of modern belts adheres to pulley grooves through friction power, to lessen the tension required to transmit torque. The very best section of the belt, known as the tension or insulation section, includes fiber cords for increased strength as it carries the load of traction power. It helps hold tension members set up and functions as a binder for better 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 resistance with OE quality match and structure for reliable, long-long lasting performance.
V-Belts are the most typical type of drive belt used for power transmission. Their primary function is certainly to transmit power from a principal source, just like a engine, to a second driven unit. They provide the best mixture of traction, acceleration transfer, load distribution, and extended service life. Most are limitless and their cross section is definitely trapezoidal or “V” formed. The “V” shape of the belt tracks in a similarly formed groove on a pulley or sheave. The v-belt wedges in to the groove as the load raises creating power distribution and torque. V-belts are generally made of rubber or polymer or there might be fibers embedded for added strength and reinforcement.
V-belts are generally within two V Belt construction groups: envelope (wrapped) and raw advantage.

Wrapped belts have an increased level of resistance to oils and intense temperatures. They can be utilized as friction clutches during set up.
Raw edge type v-belts are more efficient, generate less heat, enable smaller pulley diameters, boost power ratings, and provide longer life.
V-belts appear to be relatively benign and simple pieces of equipment. Just measure the top width and circumference, find another belt with the same measurements, and slap it on the drive. There’s only 1 problem: that strategy is about as wrong as possible get.
