Cogged Belt
When a belt is connected to a drive system, the first requirement is that it remain linked to the system and rotate in unison with it. Its secure connection guarantees that the motor will perform flawlessly without malfunctioning or errors. Early V-belt designs tended to have problems with slippage, wear, and a negative reaction to lubricants. In answer to the problems with V-belt design, engineers developed the cogged belt that securely formed a tight connection with drive systems.

The History of Cogged Belts
When cogged belts replaced V-belts, they were made with round cogs since it was felt that round ones would slide easily into the notches of a pulley. They worked perfectly, for most applications, but had problems with jumping and slipping during stressful conditions. To resolve the problem, belt manufacturers created cogs or nubs that were square and flat that could fit snuggly and tighter into the notches of the drive system and not be prone to slippage.
Benefits of Cogged Belts
As engines have developed, they have placed greater demands on every one of their parts from the gears to the drive system. These advancements have placed increased stress on the cog belts, which have to be able to withstand the greater speeds, loads, and tension. Modern cogged belts are known for their ability to withstand the demands of today’s engines and are the most reliable part.
Durability, endurance, reliability, and being lightweight are the constant demands of modern machinery. As new developments are introduced, great demands are placed on every part of machines, including drive belts. The ever growing requirements are the reason that cog belts have become such an important part of equipment development. Their ability to perform under harsh and stressing conditions has made them a major part of engine development.
Design of Cogged Belts
A cogged belt has small cogs or nubs that fit into notches or sprockets on a drive system pulley. They ensure that the belt will mesh perfectly at every rotation of the system.
The cogs, or nubs, on a cogged belt are placed on its underside and are evenly spaced to match with the pulley of the drive system. They are engineered from lightweight materials such as Kevlar, polyester, synthetic rubber, or some other form of durable material. Their design and shape is engineered to operate at peak efficiency and exceptional endurance.
There are certain things that designers want to have that they can rely on for perfect performance. In recent years, one of those parts has been the cog belt and its well-engineered design.
