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 as a result of the belt’s adherence to the pulley) are an economical option for industrial, auto, commercial, agricultural, and home appliance applications. V-belt drives are also simple to install, require no lubrication, and dampen shock load.
Here’s the catch: Standard friction drives can both slide and creep, resulting in inexact velocity ratios or degraded timing precision between input and output shafts. For this reason, it is important to choose a belt appropriate for the application accessible.
Belt drives are one of the earliest power transmission systems and were trusted during the Industrial Revolution. Then, toned belts conveyed power over large distances and were made from leather. Later, needs for better machinery, and the growth of large markets like the automobile industry spurred new belt designs. V-belts, with a trapezoidal or V shape, manufactured from rubber, neoprene, and urethane synthetic materials, replaced toned belts. Now, the improved overall surface area material of contemporary belts adheres to pulley grooves through friction push, to lessen the tension required to transmit torque. The very best V Belt section of the belt, known as the tension or insulation section, includes fiber cords for increased strength since it carries the strain of traction power. It can help hold tension members set up and acts as a binder for higher adhesion between cords and additional sections. This way, 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 match 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 to transmit power from a primary source, like a engine, to a second driven unit. They offer 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” designed. The “V” shape of the belt tracks in a similarly designed groove on a pulley or sheave. The v-belt wedges in to the groove as the strain raises creating power distribution and torque. V-belts are generally made of rubber or polymer or there may be fibers embedded for added strength and reinforcement.
V-belts are generally within two construction groups: envelope (wrapped) and raw advantage.
Wrapped belts have an increased level of resistance to oils and intense temperature ranges. They can be utilized as friction clutches during start up.
Raw edge type v-belts are more efficient, generate less heat, allow for smaller pulley diameters, increase power ratings, and provide longer life.
V-belts look like relatively benign and basic devices. Just measure the best width and circumference, discover another belt with the same measurements, and slap it on the drive. There’s only 1 problem: that approach is about as wrong as you can get.
