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 known as friction drives (because power is usually transmitted consequently of the belt’s adherence to the pulley) are a cost-effective option for industrial, automotive, 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 can both slip and creep, leading to inexact velocity ratios or degraded timing precision between input and output shafts. For this reason, it is important to select a belt befitting the application accessible.
Belt drives are among the earliest power transmitting systems and were widely used through the Industrial Revolution. After that, toned belts conveyed power over large distances and were created from leather. Later, needs for better machinery, and the development of large markets such as the automobile sector spurred new belt designs. V-belts, with a trapezoidal or V shape, manufactured from 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 pressure, to lessen the tension necessary to transmit torque. The top part of the belt, known as the tension or insulation section, consists of fiber cords for improved strength as it carries the load of traction push. It helps hold tension members in place and works as a binder for higher adhesion between cords and various other sections. In this manner, heat build-up is decreased, extending belt life.
We’ve designed our V Belt V-belts for wear, corrosion, and heat resistance with OE quality suit and construction for reliable, long-long lasting performance.
V-Belts are the most common type of drive belt used for power transmission. Their primary function is usually to transmit power from a main source, just like a electric motor, to a secondary driven unit. They provide the best combination of traction, rate transfer, load distribution, and extended service life. The majority are countless and their cross section is definitely trapezoidal or “V” formed. The “V” shape of the belt tracks in a similarly formed 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 commonly made of rubber or polymer or there may be fibers embedded for added strength and reinforcement.
V-belts are generally within two construction types: envelope (wrapped) and raw edge.
Wrapped belts have an increased resistance to oils and severe temperatures. 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, enhance power ratings, and offer longer life.
V-belts look like relatively benign and simple pieces of equipment. 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 about as wrong as possible get.
