Guide to V Belt Selection and Replacement

Advances in V belt technology present users the opportunity to upgrade older drives and gain improvements in performance while saving time and money. For example, industry standard V belts subject to extreme operating conditions, such as stifling heat inside a belt guard, can fail prematurely from heat cracks, stretching or excessive wear. Frequently retensioning and replacing the belts leads to downtime, inefficiency and loss of productivity.

With today’s new technologies, however, you can upgrade to notched V belts made from an ethylene rubber material that can withstand temperature extremes from -70°F (-57°C) to +250°F (+121°C), an 88% improvement over the temperature range for industry standard V belts. These newer belts resist hardening to avoid cracking, offer improved flexibility, and run smoother in the sheaves to reduce vibration and extend the life of other drive components, such as shafts and bearings.

As another example, replacing an older, classical V belt drive with a newer, narrow profile notched V belt made with an ethylene elastomer and aramid fiber tensile cords can yield up to 3x greater load carrying capacity while reducing the weight and size of the drive, relieving stress on shafts, bearings and other components.

When it comes to V belt drives with multi-groove sheaves, consider your options. If the sheaves are not worn, you can use fewer, higher-performance belts (leaving open grooves), or fill all the grooves with higher-performance belts to increase drive load capacity and extend belt life. If the sheaves are worn and need replacement, you can upgrade to a more compact (but equally powerful) drive to save weight and space, or keep the same drive configuration while increasing drive capacity.

Timing belts guidance

The tooth profile of timing belts is based on the AT tooth profile, but the teeth are crowned. The timing belt is thus guided and self-centred, which eliminates flanges on the pulleys and eliminates lateral drift of the timing belt. The timing belt with an arched BAT profile reduces noise. The meshing of the timing belt is optimised.

Caution: it requires a perfect alignment of the pulleys and turns only in one direction. (For two directions of rotation, use BATK provided with a guide).

ADVANTAGES

> Self-steering: flangeless pulleys

> Very low noise level: less vibration when meshing

> Very weak polygonal effect

> Vibrations are suppressed when using support rollers or idlers on the tooth side (no minimum angle of wrap).

New Poly V Belts offer multiple benefits

Poly V belts are multi-V cross section belts with longitudinal v-shaped ribs, that mate perfectly with the corresponding pulley grooves.

Poly V belts combine the high flexibility of Flat belts with the first-rate power transmission of V belts. Poly V belts are ideal for serpentine drives and large transmission ratios including automotive applications (EPDM). Versions are also suitable for compact friction-locked drives in household appliances and heavy machinery.

They enable economic solutions even under difficult drive conditions, such as large transmission ratios, high belt speed ratios, small pulley diameters and back idler pulleys.

How to Replace a Fan Belt in Your Car

If you’re old enough to remember the good old days when you changed your own fan belts, then you can also remember the bruised knuckles and cursing that went along with it. And to make matters worse, there were often two or three belts to change.

Now, instead of separate belts for each component, most cars today use a single wider, multigrooved “serpentine” fan belt, named for the way it snakes around multiple pulleys.

Serpentine fan belt replacement is easy because today’s automatic drive fan belt tensioners eliminate the need to loosen bolts or pry components into position for retensioning. Just rotate the tensioner, remove the old belt and install a new one. When the fan belt ribs are seated into the pulley grooves, release the tensioner and you’re done.

What Is a Drive Belt?

What Is a Drive Belt? Here’s What You Need to Know

There are three types of drive belts:

1. Serpentine Belt

A serpentine belt is located under the hood of a car, and it “snakes” its way between various pulleys and accessories. This type of drive belt is usually found in cars produced after 1990. It also tends to last longer than other types of drive belts, is simple to install and remove, and transmits power between a car’s air conditioner compressor, water pump, alternator, and steering pump.

2. V-Belt

A V-belt runs off a crank and pulley and typically travels between one or two engine accessories. Older cars often have several V-belts used for power steering, air conditioning, and other operating essentials. V-belts can be more difficult to change than serpentine belts. Additionally, if V-belts become loose, they can cause your alternator to malfunction and lead your engine to overheat.

3. Timing Belt

A timing belt links your car engine’s crankshaft to its camshaft; the crankshaft helps the engine’s pistons rotate, while the camshaft helps open and close engine valves. It can be tough to see the timing belt due to the fact that it is likely hidden underneath a timing cover. However, the timing belt should not be ignored; otherwise, if the timing belt wears down and malfunctions, it may result in a costly, time-intensive engine rebuild.

How Often Should You Change the Belts in Your Car?

It is often beneficial to change the drive belts in your car approximately every 60,000 to 100,000 miles. By undergoing annual car inspections, you can have your drive belts evaluated. If any signs of damage or severe wear and tear are identified, the belts can be replaced.

Types of transmission belts

There are many size and shapes belts used in transmission belt but today we are describe the mostly used belts.

According to the Shape:

1. Flat belt:

This belt is mostly used in the factories and workshops, where a moderate amount of power is to be transmitted, from one pulley to another when the two pulleys are not more than eight meters apart.

2. V- belt:

The V-belt is mostly used in the factories and workshops where a moderate amount of power is to be transmitted form one pulley to another, when the two pulleys are very near to each other.

3. Circular belt or rope:

The circular belt or rope is mostly used in the factories and workshops, where a great amount of power is to be transmitted, from one pulley to another, when the two pulleys are more than eight meters apart.

4. Timing belt or toothed belt:

These belts are used for power or motion transmission with accurate timing. These belts have toothed surface with meshed with the pulley so it is not a ordinary belt works on friction. This belts required special type of pulley so it is most expensive belt. This is used to obtain accurate timing.

Are all v belts the same?

How To Measure V Belts

Belts are NOT measured by diameter nor folding the belt in half. The most accurate way to measure the circumference of a v belt is with a v belt measuring tool or using a cloth tape measure (Not a steel tape measure or ruler). An additional option is to wrap a small diameter string/rope around the v belt, then measure the length of the string. When measuring be sure to have the v belt under slight tension and the cloth tape measure is tightly against the back of the v belt. Also, keep in mind belts do stretch and unfortunately there is no specific value for how much a v belt can stretch. You’ll also need to measure the width and depth to determine which section v belt you have.

How to determine the v belt number

All A,B,C,D,E,AX,BX belts list the inside circumference measurement after the letter of the v belt part number. Example: A88 has a 88″ inner circumference, then you add 2 inches for the A Section (Listed below) to obtain the outer circumference. If you measure the outer circumference, then you would subtract the number of inches based on the section you have (Listed below) to obtain the v belt number. This is also the same for the banded belts. Measure each individual band for banded belts to obtain the correct width.

How fractional & v belt numbers are coded

All sections 3L,3V,5V,8V,3VX,5VX v belts have the outside circumference after the number and letter(s). Example: v belt # 3V600 has a 60″ outside circumference. Inside circumference are not measured for these sections. This is also for the banded belts. Measure each individual band for banded belts to obtain the correct width.
