COGGED V BELTS

Leave a comment

When choosing what type of cogged v belt to purchase it is important to consider which style will be best for your application. Classic on-cogged v belts are economical when it comes to the upfront cost, but this does not remain true for long-term and frequent usage. Cogged belts are designed with slots that run perpendicular to the length of the belt, this design greatly decreases bend resistance of the belt. Because they are dimensionally equivalent minus the slots cogged belts can run on the same pulleys you are already using for standard cogged v belts. This style of belt is especally useful in high-speed compact drives. USA Roller Chain and Sprockets (USARC) is a premier supplier of AX, BX, and CX single and banded cogged v belts.

BENEFITS OF COGGED V BELTS

The benefits of using a cogged v belt include longer operational life, cooler running, and around a 2% higher efficiency raring than a standard cogged v belt.

Cost Savings Analysis Example:

Let’s say we are running a 100 horsepower supply air fan motor that is rated at 93% efficient and operates at a consistent load of 75%, and it consumes 527,000 kWh annually. When switching from a 93% efficient (E1) cogged v belt to a 98% efficient (E2) cogged v-belt, with electricity priced at $0.05/ kWh here’s what the savings are and how it is calculated.

Energy Savings= annual energy use x(1 – E1/E2)

= 527,000 kWh/year x(1-93/98)= 26,888 kWh/ year

Annual Savings= 26,888 x $0.05 kWh = $1,345/ annually

What Are The Different Types Of V Belts?

Leave a comment

V belts are one of the many different types of conveyor belts available. These belts are different from the other varieties because there is only one strand of v belt found underneath the roller bed. This belt can be found on one of the sides of the rollers right next to the belt’s side-frame. These belts run in the opposite direction from that of whatever contents the v belt is conveying. These types of belts are best for light or medium duty loads and are not the best in environments that are moist or oily. One of the great things about these belts is that in order for the belt to function, only very light contact between the belt and the bed rollers is necessary.

Types Of V belts

Although there are many options available when selecting the best v belt for your business, there are two main types of belts, poly v belts and variable speed v belts. Poly v belts are ideal for those who want a flexible belt that will offer smooth performance along with a low profile design and the capability to work at high speeds. The variable speed v belt on the other hand can work with sheave drives of variable speeds and because of this it requires a great deal of lateral rigidity to help maintain a consistent speed control.

More Options

In addition to selecting between poly v belts and variable speed v belts, there are also other options you can make to customize your v belt, making it unique. These belts can come in a wide variety of surfaces depending on what is required for the function they will perform. Some of the most common types of v belts include ribbed ones, notched ones, cogged ones, banded ones, wedged ones and smooth ones, each of which is specifically designed to help serve a different purpose. The guides for the v belts can also come in several types, mostly based on shapes and surface with the most common shapes being a triangle profile, a rectangle profile, a special rectangular profile (with rounded corners) and a special v-profile (a trapezoidal shape).

Normal Uses

V belts are widely used because of their versatility as well as ability to handle directional changes that might prove challenging with other types of conveyor belts. They can be used for basic tasks such as product alignment, offsetting connections, diverting, merging and directional changes. Because of these functions, they are ideal for many industrial applications and are very common in power transmission/driving, conveying, sequencing and timing. The different types available are what make v belts so versatile.

Features

No matter which type of v belt you select or what surface you opt for, there are several features that are common for all of these belts. They will all follow a belt path which eliminates the risk of bending back the belt and because of their abilities with directional changes they are usually available in tight radius configurations. They will almost always have automatic drive pressure and true taper rollers in addition to sleeves that allow them to move the product through curves quietly while still maintaining their orientation.

What is cogged v belt?

Leave a comment

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

Leave a comment

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

Leave a comment

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

Leave a comment

General

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.

Operation

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).

Advantages

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

Leave a comment

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

Leave a comment

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

Leave a comment

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.
