Everything You Need To Know About Wedge Belts

Friday, August 5th, 2016

While the word “belt” makes many people picture clothing, in the industrial world, it means something different.

A belt is a loop of material that is used to link at least two rotating shafts together. The material that the belt is made from is always flexible, and the rotating shafts are usually parallel to one another.

There are many different kinds of belts used on various types of machinery. One example is wedge belts, which are also known as v-belts. These belts are commonly used for high powered devices.

Friday, June 19th, 2015

Do you like to have all the info?

We’re like you. We like to do the research, and know firsthand what the companies and products we work with are “all about.”

That’s why today we are shining the proverbial spotlight on the company Optibelt, part of the Arntz OPTIBELT Group. Optibelt is a successful, and well known v-belt producing corporation whose headquarters recently re-located to Carol Stream, Illinois.

Optibelt has facilities in South Carolina, Texas, and California, as well; each with the capability of making custom cut widths for timing belts, banded v-belts, cogged v-belts, and ribbed belts.

In 2014, Optibelt was recognized for their third consecutive year as a Partner-Level Supplier in John Deere’s Achieving Excellence Program. Status as a Partner-Level Supplier is Deere & Company’s highest supplier rating.

It comes as no surprise that John Deere continues to recognize this outstanding company. Optibelt was chosen for this honor for their dedication to providing products and services of outstanding quality, and for their commitment to continual improvement.

Global Key Account Manager, Louis Giles, along with OEM Product Specialist, Waldemar Giesbrect accepted the award during the ceremonies that were held in Davenport, IA. Giles remarked, “This award is a great honor as it represents Optibelt’s ability deliver the very best products and service in the industry year after year.”

We certainly agree with him on that point.

Several key performance categories are looked at including quality, cost management, delivery, technical support and responsiveness.

Does it really matter to us that Optibelt was recognized by John Deere for their commitment to being a superior supplier?

Yes. It matters, because it shows continued commitment to their customer. It also shows us that they are currently capable of giving great service. They’re not up-and-coming. They’ve “made it.”

In other news, with their new headquarters located in northern Illinois, Optibelt USA can offer its customers even better service. This was a necessary relocation in response to the continuously growing market.

There are plenty advantages to the new location:

With 2500 square meters of space, more goods can be warehoused and shipped quickly to customers, because of added personnel. Not only can they increase inventory of their main product lines, Optibelt will also be able to maintain an inventory of new products and keep them continuously in stock. Lastly, being near to the metropolis region of Chicago has its benefits in the area of excellent transportation connections.

Here’s to v-belts, and the v-belt suppliers that continually meet our needs.

Tensioning V-Belts

Friday, November 7th, 2014

We’ve all been there. One after another, we see or hear about equipment failure or breakage right under our noses.

What is the cause?  If we’re not careful, it could be neglect.  Let’s not have that happen again – at least not to our v-belts. This article will be a valuable resource for you and your team when it comes to proper v-belt care. I am going to lay out for you how to properly re-tension your v-belts. And I’ll tell you why…

Do you want to prevent premature v-belt failure?

Take this precaution to ensure long and successful operation from your v-belts. Tensioning is the single most important factor necessary for continual satisfactory performance. Without it, you will see slippage and rapid wear and tear which could be costly.

The proper tension for operation is the lowest tension at which the belts won’t slip at peak load. An under-tensioned belt will slip and cause heating and cracking. An over-tensioned belt may cause stretching and reduce belt life.

For this project, you will need a tension measuring tool. There are several on the marketplace. If you need a recommendation for your specific application, let me know

First order of business is, of course, safety! Be certain to turn off power to the motor and follow lock out procedures.

In order to re-tension your v-belt, you must first measure strand deflection. To begin, measure the belt’s span in inches – the distance from the center of the first wheel to the center of the second. The formula for deflection is then this number divided by 64, or 1/64th per inch of span length.

Then place the tension checker at the center of the belt. If this is a single belt, you will need to lay a ruler from wheel to wheel for a reference.

Push the tensiometer down until the rubber part is level with the ruler. You will then need to use the tension charts for your belt to check your tension against recommended settings. Follow the chart from left to right for the belt you have in front of you. It is recommended to re-tension each belt.

Keep in mind that tension is always changing. In an ideal situation, re-tension should occur after 20 min, 24 hours and again after 48 hours for a new belt.

If this isn’t possible for your schedule, simply run the belt a few revolutions with your hand, which will help the belt wedge down in the groove of the sheave. This is called seeding.

Once properly seeded, you will notice a decrease in deflective force, which means you will need to re-tension the belt again. Each belt should be re-tensioned after 8 hours of use, or daily, for heavily used v-belts.

Replacing V-Belts with Cogged or Synchronous Belt Drives

Friday, April 11th, 2014

Around 1/3 of the electric motors within the commercial and industrial sectors make use of belt drives. Flexibility is one of the things that belt drives boast of when it comes to the positioning of the motor relative to the load.

Pulleys (sheaves) of different diameters make it possible for the speed of the driven equipment to be adjusted. A properly designed belt transmission system comes with high efficiency, low noise, needs little if any lubrication, and is not very high-maintenance. But there are belts that offer more efficiency as compared to others. To be specific, you can have significant energy cost savings with them.

Most belt drives use V-belts. V-belts use a trapezoidal cross section so as to make a wedging action on the pulleys in order to boost friction as well as the belt’s power transfer capability. Multiple or joined belts are specifically used for heavy loads.

V-belt drives are able to reach a peak efficiency of 95% to 98% at the time of installation. Such efficiency will also be in accordance with pulley size, driven torque, under or over-belting, and V-belt design and construction. Efficiency declines (to a nominal efficiency of 93%), but can much lower with time, especially in the event slippage takes place due to the belt not being periodically re-tensioned.

Cogged belts contain slots that run perpendicular to the length of the belt. The bending resistance of the belt is reduced by the slots. Cogged belts could be utilized with the same pulleys as equally rated V-belts. They are known to run cooler and they last longer. They also have an efficiency around 2% higher as compared to that of standard V-belts.

Synchronous belts, also dubbed as timing, positive-drive, or high-torque drive belts, are toothed and they call for the installation of mating toothed-drive sprockets. Synchronous belts come with an efficiency of around 98% and they get to hold on to such efficiency over a wide load range.

On the other hand, V-belts have a sharp reduction in efficiency at high torque because of cumulative slippage. Synchronous belts need less maintenance and re-tensioning, run in wet and oily environments, as well as run slip-free. However, synchronous belts can be quite noisy, not fitting for shock loads, as well as transfer vibrations.

Classical V Belts Dimensions in Agriculture

Friday, January 31st, 2014

More than 66 different dimensions, sizes, and types of belts are utilized in the agriculture equipment industry. Such belts are being used in tractors, balers, and snow blowers, among others.

V Belts can be found in fan belts, timing belts, drive belts for mowers, as well as general pulley driven devices found in combines, mowers, balers, and other agricultural equipment.

To be able to change a V belt that has any cut or damage, it should be identified beforehand. How to identify a belt? Of course you can look at the V belt part number written on it. But, when that’s not possible you need other means.

The basic V belt has a trapezoidal cross section, with equal sides, and different lengths at the top and bottom. There are 5 common belt types (called Classical V Belt), defined as A, B, C, D and E. The five principal dimensions of a V Belt are the top width, pitch width, height, angle, and effective circumference.

  • The A model has a top width of 13mm (1/2 inch) and a height of 8 mm (5/16th of an inch).
  • The B model has a top width of 17mm (21/32nd of an inch) and a height of 11 mm (13/32nd of an inch).
  • The C model has a top width of 22 mm (7/8th of an inch) and a height of 14 mm (17/32nd of an inch).
  • The D model has a top width of 32 mm (1 1/4th of an inch) and a height of 19 mm (3/4 of an inch).
  • The E model has a top width of 38 mm (1 1/2th of an inch) and a height of 23 mm (29/32nd of an inch). All classical belts have angles of 40 degrees.

Its length is another major variant of this component. You can measure the standard outside and inside circumference of the belt, but for measuring and part number identification purposes, this is not the effective circumference.

Classical industrial belts are specified in terms of pitch length.  The pitch length is normally the length at the belt pitch line. This line is generally located at the neutral axis near the cord line and varies with cross section and construction.

The effective circumference, or effective length, is the outside diameter at a specified tension.  Such circumference is measured where the groove top width is a dimension as specified by RMA, ASAE or SAE standards.

Some manufacturers and users choose the pitch length to identify belts, but the majority opt for the effective circumference of the belt for identification purposes.
