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 called friction drives (because power can be transmitted as a result 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 easy to install, require 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 insight and output shafts. For this reason, it is essential to select a belt befitting the application at hand.
Belt drives are among the earliest power transmission systems and were widely used during the Industrial Revolution. After that, flat belts conveyed power over huge distances and were made from leather. Later, needs for better machinery, and the development of large markets like the automobile industry spurred new belt styles. 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 power, to lessen the tension required to transmit torque. The very best portion of the belt, called the strain or insulation section, consists of fiber cords for increased strength as it carries the load of traction push. It helps hold tension members in place and functions 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 match and construction for reliable, long-long lasting performance.
V-Belts are the most common kind of drive belt used for power transmitting. Their primary function is definitely to transmit power from a main source, such as a engine, to a secondary driven unit. They offer the best mixture of traction, rate transfer, load distribution, and extended service life. Most are endless and their cross section is usually trapezoidal or “V” designed. The “V” form of the belt tracks in a similarly designed 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 manufactured from rubber or polymer or there might be fibers embedded for added strength and reinforcement.
V-belts are generally found in two construction classes: envelope (wrapped) and raw advantage.
Wrapped belts have an increased level of resistance to oils and extreme temperature ranges. They can be utilized as friction clutches during start up.
Raw edge type v-belts are better, generate less heat, enable v belt china smaller pulley diameters, increase power ratings, and provide longer life.
V-belts appear to be relatively benign and simple 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 you can get.
