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 can be transmitted because of this 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: Regular friction drives may 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 choose a belt appropriate for the application accessible.
Belt drives are among the earliest power transmitting systems and were widely used through the Industrial Revolution. After that, smooth 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 industry 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 improved overall surface area material of contemporary belts adheres to pulley grooves through friction force, to lessen the tension required to transmit torque. The top section of the belt, called the tension or insulation section, consists of fiber cords for improved strength since it carries the load of traction pressure. It can help hold tension members set up and functions as a V Belt binder for greater adhesion between cords and additional sections. In this manner, heat build-up is reduced, 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-lasting performance.
V-Belts are the most common type of drive belt used for power transmission. Their primary function is to transmit power from a principal source, such as a electric motor, to a secondary driven unit. They offer the best mixture of traction, quickness transfer, load distribution, and extended service life. Most are endless and their cross section is certainly 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 into the groove as the strain raises creating power distribution and torque. V-belts are commonly made of rubber or polymer or there may be fibers embedded for added strength and reinforcement.
V-belts are generally found in two construction categories: envelope (wrapped) and raw advantage.
Wrapped belts have an increased level of resistance to oils and severe temperature ranges. They can be used as friction clutches during start up.
Raw edge type v-belts are better, generate less heat, allow for smaller pulley diameters, boost power ratings, and provide longer life.
V-belts appear to be 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 one problem: that strategy is approximately as wrong as possible get.
