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 usually 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, require no lubrication, and dampen shock load.
Here’s the catch: Regular friction drives may both slip and creep, resulting in inexact velocity ratios or degraded timing precision between insight and output shafts. Because of this, it is essential to select a belt befitting the application at hand.
Belt drives are among the earliest power transmitting systems and were trusted through the Industrial Revolution. After that, smooth belts conveyed power over large distances and were created from leather. Later, needs 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 increased overall surface area material of contemporary belts adheres to pulley grooves through friction drive, to reduce the tension required to transmit torque. The very best portion of the belt, known as the tension or insulation section, consists of fiber cords for improved strength as it carries the strain of traction push. It helps hold tension members set up and acts as a binder for greater 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 level of resistance with OE quality suit and building for reliable, long-long lasting performance.
V-Belts are the most typical type of drive belt used for power transmission. Their primary function is to transmit power from a primary source, just like a electric motor, to a second driven unit. They provide the best combination of traction, speed V Belt transfer, load distribution, and extended service life. Most are endless and their cross section is trapezoidal or “V” formed. The “V” form of the belt tracks in a likewise shaped 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 may be fibers embedded for added power and reinforcement.
V-belts are generally found in two construction types: envelope (wrapped) and raw advantage.
Wrapped belts have a higher level of resistance to oils and intense temps. 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, enhance power ratings, and offer longer life.
V-belts look like relatively benign and basic 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 strategy is about as wrong as you can get.
