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 called friction drives (because power is usually 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, need 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. For this reason, it is important to select a belt befitting the application at hand.
Belt drives are among the earliest power tranny systems and were trusted through the Industrial Revolution. After that, flat belts conveyed power over large distances and were made from leather. Later, needs for better machinery, and the growth of large markets such as the automobile industry 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 material of modern belts adheres to pulley grooves through friction force, to lessen the tension necessary to transmit torque. The very best area of the belt, known as the tension or insulation section, contains fiber cords for increased strength since it carries the load of traction force. It can help hold tension members set up and functions as a binder for higher adhesion between cords and various other sections. This way, 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-long lasting performance.
V-Belts are the most typical kind of drive belt used for power transmitting. Their primary function is certainly to transmit power from a major source, just like a engine, to a secondary driven unit. They offer the best combination of traction, rate transfer, load distribution, and extended service life. The majority are limitless and their cross section is definitely trapezoidal or “V” shaped. The “V” shape of the belt tracks in a likewise designed groove on a pulley or sheave. The v-belt wedges in to the groove as the strain improves 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 found in two construction categories: envelope (wrapped) and raw edge.
Wrapped belts have a higher resistance to oils and intense temps. They can be used 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 appear to be relatively V Belt benign and simple devices. Just measure the top width and circumference, discover another belt with the same dimensions, and slap it on the drive. There’s only 1 problem: that approach is about as wrong as you can get.
