What is cogged v belt?

The cogged v belt is a temperature and oil resistant universal drive belt that has antistatic properties and due to its design can be used with small pulley diameters. It is suitable for industrial machinery, agricultural equipment and automotive applications.

Construction and Features

The tensile member consists of a specially treated high strength polyester cord to transmit tensile forces and withstand shock loads.

The cogged v belt compound converts tensile forces on the sidewalls into longitudinal forces in the tensile member.

The moulded cogged design provides high flexibility as well as lower operating temperatures.

The History of Drive Belts

In the very early days of the automobile, there were no accessories, which meant that there was no need for accessory drive belts. The very first use of a drive belt was to power radiator fans in early water cooling systems, and when water pumps were introduced, they were also belt-driven. These early belts were v-belts, but they were made out of leather, and as of 1916, the angle of the wedge varied widely from one application to another.

The first rubber v-belt was created in 1917 by the Gates Rubber Company, which is still one of the leading manufacturers of drive belts in the world today. Another early innovation was the multiple v-belt drive, which was patented in 1925. This setup used multiple v-belts in parallel, which is a technique that was widely used until the eventual transition to serpentine belts.

Drive belts remained relatively unchanged for decades, although production materials and techniques were incrementally improved. The next major development was the introduction of the serpentine belt, which first appeared for the 1985 model year of the Mercedes-Benz 190 series.

Today, most vehicles use a single serpentine belt. However, some engines utilize multiple serpentine belts, and there are even some examples where a serpentine belt and a v-belt are both used.

Replace V-Belts With Cogged V Belt

About one-third of the electric motors in the industrial and commercial sectors use belt drives. Belt drives provide flexibility in the positioning of the motor relative to the load. Pulleys (sheaves) of varying diameters allow the speed of the driven equipment to be increased or decreased. A properly designed belt transmission system provides high efficiency, decreases noise, requires no lubrication, and presents low maintenance requirements. However, certain types of belts are more efficient than others, offering potential energy cost savings.

The majority of belt drives use V-belts. V-belts use a trapezoidal cross section to create a wedging action on the pulleys to increase friction and improve the belt’s power transfer capability. Joined or multiple belts are specified for heavy loads. V-belt drives can have a peak efficiency of 95 percent to 98 percent at the time of installation. Efficiency is also dependent on pulley size, driven torque, under or over-belting, and V-belt design and construction. Efficiency deteriorates by as much as 5 percent (to a nominal efficiency of 93 percent) over time if slippage occurs because the belt is not periodically retensioned.

Cogged v belts have slots that run perpendicular to the belt’s length. The slots reduce the bending resistance of the belt. Cogged v belts can be used with the same pulleys as equivalently rated V-belts. They run cooler, last longer, and have an efficiency that is about 2 percent higher than that of standard V-belts.

V Belt Application and Design Considerations


V belts are the workhorse within industry, available from virtually every distributor and adaptable to practically any drive. They are presently available in a wide variety of standard sizes and types, for transmitting almost any amount of load power.


Typically, V belts drives operate best at speeds between 1500 to 6000 ft/min ( 8 and 30 m/s). For standard belts, ideal peak capacity speed is approximately 4500 ft/min (23 m/s). Narrow V belts, however, will operate up to 10,000 ft/min (50 m/s).


V belt drives permit large speed ratios and provide long life. They are easily installed and removed, quiet, and low maintenance.

Initial Selection adn Design COnsideration V belt Application

  1. How much power do you need to transmit and at what speed?
  2. Service Factor V belts your particular application.
  3. Determine theV belt design horsepower.
  4. Based on your results, determine which belt section would be appropriate for your drive – See V belt supplier. Narrow belt sheaves are more compact than Classical belt sheaves. Some belts are more appropriate for specific applications.
  5. Determine theratio of your drive application based on the Ratio formula – center distance has been pre-selected based on the drive size.
  6. Find the number of belts required by dividing the design horsepower by the belt/HP.
  7. Verify the validity of this drive by consulting the number of grooves available in these sheave sizes.
  8. Verify if dynamic balancing is needed for each sheave based on the Dynamic orTwo-Plane Balancing formula.

Basics of drive belt

Power transmission belting has been used for more than 200 years. The first belts were flat and ran on flat pulleys. Later, cotton or hemp rope was used with V-groove pulleys to reduce belt tension. This led to the development of the vulcanized rubber V-belt in 1917. The need to eliminate speed variations led to the development of synchronous or toothed belts about 1950 and the later development of fabric-reinforced elastomer materials.

Today, flat, V, and synchronous belting is still being used in power transmission. When compared to other forms of power transmission, drive belts provide a good combination of flexibility, low cost, simple installation and maintenance, and minimal space requirements.

Drive belt equipment uses readily available components. Replacement parts can be easily obtained from local distributors. This availability reduces downtime and inventory. Sheaves and pulleys are usually less expensive than chain drive sprockets and have little wear over long periods of operation.

Poly V Belts

With efficient torque drive and high ratio, Poly V Belts are ideal if you need high speed drives within small centre distances.

Poly V Belts can be used with smaller pulleys and, since there is an increase in the belt’s surface engagement, their drive width can be reduced, increasing the horsepower per inch ratio of the belt width compared to the much larger size of standard V Belts.

Poly V Belts are ideal as they provide smooth running, low noise operation, and are quick to fit and maintenance free.

Power Transmission Belts

Power transmission belts, sometimes called drive belts, gear belts, or automotive belts, transmit power between two components, such as from a motor or driver to a drive shaft or pulley. Round belts are used on serpentine drives, line shaft conveyors, and commercial sewing machines.

Connectors are used to connect two ends of a round belt that has been cut to size or needs to be installed without disassembling the drive system. Twisted O-rings are installed in V-belt and round belt pulleys and have a hook connector so they can be installed without dismantling the drive system.

Variable-speed belts are used with variable-speed pulleys and accommodate changes in speed and pulley width as the drive systems speeds up and slows down. Protect, maintain, and measure belt grooves and tension using belt accessories.

Uses of Conveyor Belting in the agricultural industry

In today’s world where transportation is perhaps one of the most elements for the business to succeed, people are always in search of better, faster and cost effective technique of transporting, tracking and processing their goods.

In the recent years, conveyor belt system has emerged as one of the best ways of transporting product. This system consists of two or more number of drums that are also referred as pulleys with a conveyor belt i.e. the carrying medium and it rotates around the drums. The belt is propelled by one or two of the pulleys. The pulley that powers the belt is called the drive pulley and the other is called idler pulley. The conveyor belt is categorized into two classes, one that transports general material and the other that is responsible for taking agricultural material such as sand, ore, coal, salt, grain and much more from one place to another.

Uses of Conveyor in the agricultural community

The uses of a conveyor belt in the agricultural community are numerous. It is used in the feeding process that processes or freezes vegetables, fruits, and other agricultural products for packing to be sent to the retailers or other process plants. Besides this, these belts are effectively being used for loading bulk quantities into trucks in order to get them transported to their final destination. Bean market is another place, where conveyor belt scales are used in a large number. Additionally, these belts are to load out the soy beans into the trucks that carry them to the end process.

These belts are designed to suit the requirements of the agricultural industry application. Sugar Cane, Cauliflower, peas, flour, rice, and grains are some of the agricultural applications that use conveyor belt scales.

Merits of using the belts in the agricultural industry

With the help of these conveyor belts, the workforce reduces and this leads to more profits and less expense. Also, the storage, drying, and processing of the products have become very efficient and easy. These processes are also easy to synchronize due to thesebelts. They have excellent turn-around time and handle the systematic materials very well.

These belts are specially designed in order to cater the needs of the agricultural world. They are not only cost effective, but also efficient. They have the ability to adjust to any type of temperature. Different conveyor belts are used to perform agriculture applications.
