Conveyor Rubber Belts

Conveyor rubber belt is the cheapest system to convey bulk solid materials over any distance. It is the topic item of a conveyor system which allows the material handling. All conveyor rubber belts are composed of two different elements:

A central resistant carcass which gives the mechanical characteristics to the product, as tensile strength and elongations. Two main belting families exist: textile conveyo rubber belts and steel cord conveyor rubber belts. See the internal part of the catalogue for a complete description.

Two rubber covers, named top and bottom covers, which protect the resistant carcass and characterize the rubber belt, as described in this page. In order to guarantee safety and long life also under hard working conditions, all type of rubber covers are antistatic and ozone protected.

Latest motion applications: Transmission belt and pulleys in new designs

Applications from consumer-grade home printers to heavy industrial conveyors use these synchronous transmission belts, because unlike V belts with trapezoidal cross-sections, they don’t slip.

Motion applications often need customized transmission belts and sprockets in urethane, double-sided, mini-pitch, and made-to-order (MTO) versions. Double-sided belts have covered teeth to transfer up to 100% of maximum-rated load from one or both transmission belt sides. These come in trapezoidal timing configurations and HTD curvilinear tooth profiles. Some run to 14,000 rpm with speed ratios to 10:1, which is enough to replace gearsets in some cases.

Double-sided belts also excel as serpentine drives in riding mowers with counter-rotating blades, printing presses, and textile machines. Urethane transmission belts maximize motion transfer, especially when incorporating polyester or aramid tensile members. Their tooth profile is a miniature version of transmission belt with standard 40° angle teeth. Speed ratios reach 8:1 and torque output is to a couple lb-in. These transmission belts excel on positioning axes, thanks to their low torque and minimal backlash — especially in printers and copiers that need clean operation.

Long belting (usually with L or H trapezoidal tooth or HTD profiles) can exceed 500 feet in some cases. They work for power transmission and axis synchronization — doing double duty as conveyors in many cases. Such transmission belts complete with rack-and-pinion sets in machine tools and X-ray equipment as a viable drive for linear strokes. One caveat: These transmission belts spliced transmit a quarter less horsepower than a comparable endless transmission belt.

How Can I Tell If My Fan Belt Is Bad?

Steering your vehicle becomes a wrestling match. If steering has become a little more challenging than it used to be, it might be a sign that your fan belt is on its way out. As the fan belt continues to lose its grip and slip, it makes power steering increasingly difficult, as your car misses the help of the water pump, which also has responsibility for driving the power steering belt.

The cabin inside your car develops disco fever. As the belt continues to lose its grip, it will struggle to turn the alternator, especially during a cold start. So you may notice that the lights inside the car, and the headlights, go dim when you start your car or whenever there’s an extra load on your battery.

Your car hits the “snooze” button when you try to start it. As your serpentine belt wears down, it has trouble turning the alternator belt consistently, which can lead to no-start problems. Sometimes it gets so bad that it kills your battery, or causes the car to intermittently fail to start, even when the battery is charged up.

Your vehicle spikes a fever. As your fan belt or serpentine belt breaks down and frays, it won’t be able to turn the water pump consistently, which slowly defeats the engine’s cooling systems and causes the temperature to rise more than it should. At first, it’ll only be a few degrees and you might just notice off hand that your temp gauge is up a few degrees more than normal. After a while, if the belt lets the water pump slide enough times, the engine will overheat.

Your serpentine belt is impersonating a snake in the grass. If you find your fan belt is no longer attached to your engine, or is lying on the ground somewhere, that is definitely a sign that it’s time to replace your fan belt.

Standards for v belt length

Length conversion table. A very important tool to work with belt specs is a v belt conversion table. That’s because the type of length for nominal length (the length to give when specifying a belt) is different for the different types of belts (for example, it is “inner length Li” for classic v belts – also the only error in the v belt conversion table linked above).

Li, Lw, La. For every v belt, one can give three lengths: inner length Li, effective length Lw and outer length La. These abbreviations are derived from German words “Innenlänge”, “Wirklänge” and “Außenlänge” respectively and might only be in use in Germany. Inner and outer length are the inner resp. outer circumference measure of the v belt, without any linear tension on the belt and in circular shape. Effective length is a fictive median length of a v belt that is the circumference at a certain depth of the belt profile. Namely, at a depth that has the “effective width” (German “Richtbreite”), for which see the corresponding column in the v belt conversion table. Lw is used as the nominal length of belts with profiles SP*, XP* and X*. Synonymous to Lw, some manufacturers use Ld or Lp.

Belt number. For classical v belts, there is another identification system in addition to the “20 x 3500 Li” type: the belt number (German “Riemen-Nr.”). It consists of the normal profile size designation letter and a number that normally corresponds to the inner length in inches (rounded, where necessary); for example, “Z 22” or “D 150”. A list of these numbers can be found on this v belt index.

Conclusions of drive belt

Drive belt and chain drives can be used for transmission of mechanical power between two rotating shafts. Drive belt drives are often cheaper than the equivalent gears and useful for transmitting power between shafts that are widely separated or nonparallel drives.

Chain drives are usually more compact than the equivalent drive belt and can be used in oily environments where the equivalent drive belt would be prone to slipping. There is a wide range of drive belt and chain drives and this chapter has served to introduce the technology and the selection and specification of wedge and flat belt, and roller chain drives.

The technology is constantly developing with new materials and surface treatments, improvements in understanding of kinematics and wear, and associated modelling procedures, and drive belts and chain drives represent an innovation opportunity area, particularly for new applications, extended life and improved reliability, as well as miniaturisation.

Timing Belts: How to Choose the Right Material For Your Next Project

Timing belts are an excellent choice for synchronization- but if the timing belt you choose isn’t in sync with the requirements of your project, it’ll make your project unstable and collide in no time.

No one wants their project to diverge from what they have pictured it to be. While timing belts is a great solution for motion control, precision, and robotics, it isn’t your typical belt easily found at a hardware. Its value extends from ensuring that every material you need is in the exact place in the exact time you want, to make sure that everything follows the right rotation, and eventually leading your industry to the direction you want to be.

There are lots of belt types. How do I know which one to choose?

With the variety of belt types out in the market, both standard and custom timing belts, not everything will work well with your project. You have to choose which one will fit your requirements the best.

Things to Consider When Choosing a Timing Belt

Aside from its type, timing belts go into a complicated series of criteria you should closely look at so as not to compromise the resulting product of your project.

Small details impact the project. From short-term effects up to the long haul. Fret not, we’ve got your backs with that one! Here are the specific things you should consider when choosing a timing belt for your next project.

Saving Energy with Efficient V Belt Drives

The cost of energy in manufacturing has a major effect on overall cost of a product. In fact, energy cost is currently one of the main drivers in reshoring, the growing movement of bringing manufacturing operations back to the United States from offshore locations. By introducing energy efficient belt drives, you can implement a simple, cost-effective solution to achieve energy savings. Proper installation and maintenance combined with the latest drive belt technology can improve efficiency through reduced energy consumption and enhance drive performance.

Regular Maintenance – Synchronous and V Belt Drives

Proper Tensioning – One third of electric motors employed in industrial and commercial applications use belt drives. The majority of these drives use wrapped (fabric covered) V belts, relying on the friction between the belt and sheave groove to transmit power. Relatively inexpensive, wrapped V belts are designed to allow for limited slippage; intended to slip only in potentially problematic situations, this slippage prevents damage to expensive driven equipment by acting as a safety fuse. The belt can slip or break rather than damaging the more expensive driven unit.

But without frequent periodic maintenance, these belt drives tend to slip excessively during normal operation and result in reduced efficiency and increased operating costs. A correctly installed wrapped V belt drive can attain 95-98% efficiency soon after installation, rapidly declining to approximately 93% efficiency during the course of normal operation. Without continued periodic tensioning maintenance, efficiency will decrease even further and components will wear more quickly. Belt drive tensioning maintenance is often neglected due to higher maintenance priorities, meaning belt drives receive attention only when a belt finally breaks. This situation can be avoided by periodically monitoring the tension and adjusting if necessary, increasing the lifespan of belts and reducing the frequency of service interruptions.

Proven Energy Saving Solutions

The U.S. Department of Energy recommends replacing V belts with proven belt drive solutions, including cogged raw edge V belts and synchronous belts, as best practice for increasing belt drive energy efficiency. Upgrading from a wrapped V belt to a raw-edge cogged belt yields an average 2% increase in efficiency, a good return for a very low-cost investment. For new drives, using synchronous belts can provide an average 5% efficiency increase compared to V belts. While increases of 2–5% may seem insignificant, when considering the energy cost savings over multiple drives and longer running times, the savings soon become substantial. The following overview of the available belt options, as well as the pros and cons of each solution, is a useful guide for evaluating and selecting the best belt for the task.

Types of timing belts

Note that a timing chain is just that – a physical linked chain, very much like a bicycle chain – as opposed to the loop of rubberised material typically found in a standard cambelt setup. There are upsides and downsides to each configuration.

The main benefit of a timing chain is of course that the metal construction makes it much more hardwearing, and far less prone to needing periodic replacement than a material belt. The drawbacks of timing chains are that they need constant lubrication to function properly, they’re a lot louder in operation than rubber or fabric-type belts, and that they can cause far more severe and widespread damage on the rare occasions that they fail catastrophically.

Moreover, the tensioners on a timing chain are controlled by the engine’s oil pressure, meaning it becomes even more critical to maintain this at the correct bar level at all times. By contrast, water pump pressure is usually what dictates the proper functioning of cambelt tensioners, which is why you’ll often get a recommendation to replace your water pump at the same time as having a new timing belt fitted.

Cambelts and timing belts provide a range of related functions in various other sorts of power transmission systems besides internal combustion engines. Common examples seen in everyday manufacturing and industrial processes include conveying belts and linear positioning belts.

Various configurations of timing belts are used in a wide range of products and processes. These might include, to name just a few:

  • Office machinery
  • Electronic data processing equipment (EDP)
  • Textile machinery
  • Wood processing machinery
  • Machine tools
  • Compressors
  • Printing machinery
  • Hydraulic gear pumps
  • Building machinery
