For our discussion here, we'll discuss two types of "Tire Couplings". In today's world, the second type (Bonded Urethane Type) is the most common and the one A.R.&E. will recommend, should your application be practical for the "Tire" type coupling solution.

Corded tire types

This design came about in the late 's as a solution for dealing with transient torque peaks and shock loads in diesel-driven pumps. Named for their resemblance to an auto tire, this design consists of two flanged hubs equipped with clamping plates, which grip the coupling's hollow, ring-shaped element, by its inner rims. Furthering the similarity, tire coupling elements usually are rubber derivative elastomers with layers of cord, such as nylon, vulcanized into the tire shape. The coupling transmits torque through the friction of the clamp applied to the inner rims of the tire and a shearing of the element. Slippage of the coupling may be expected to occur at about four times the rated torque.

The two significant limitations to the corded tire type coupling are speed and space constraints. As speed increases, the coupling exerts axial forces on the shafts due to the centrifugal forces working on the elastomer. And the geometry of the tire itself makes for a large outside diameter for its torque capability. A design variation includes an inverted tire coupling in which the tire element arcs inward toward the axis, thus overcoming the centrifugal forces at speed. This affords 10-30% higher RPM service, depending on its size.

The corded tire coupling is torsionally soft and can dampen vibration. High radial softness accommodates angular misalignment up to 4° and parallel offset up to 1/8". Rare among elastomeric couplings is its capability to allow a certain amount of axial shaft movement. These properties give corded tire designs a wide variety of applications including those driven by internal combustion engines. This coupling is offered in spacer designs as well as with hubs which can accept bushings.

Bonded Urethane Tire

This design was first marketed in the 's and has found success primarily in the process pump industry because of several features that the corded tire lacks. The design utilizes a urethane material that is bonded to two half-circle metal rings, referred to as "shoes", which are then bolted to the two hubs. Torque is transmitted from the hubs through the shoes/bonded joint and then the shear-plane of the split urethane tire.

The design offers advantages such as radial removal of the element halves, high angular misalignment capability (4°), and shock load cushioning. In its standard close coupled configuration, it can span greater BSE lengths than most in-compression couplings, and it also has the large opening in the center of the tire to allow complete flexibility in positioning shaft ends. The outside diameter (OD) of this design is also smaller than the Corded Tire type for similar shaft and torque capacities.

Spacer couplings are achieved by using the same shaft hubs and simply extending the lengths of the steel shoes onto which the elastomer is bonded. Hubs can also be reversed in their mounting orientation to further add to the BSE permutations possible. Bushings are also commonly used on this style of coupling. A heavy duty elastomer option (25% more torque) is available, but it reduces the misalignment capacity by 50%.

It has proven to be ideal in applications such as pumps, screw compressors, blowers, mixers, crushers, and general power transmission drives.

Limitations of the urethane tire type include the large number of fasteners required for installation and removal of the elastomer, and the fatigue of the element and the bond between steel and elastomer under torsional vibrations.And here's a resource for you... it doesn't have to do with just this, but instead is a general knowledge base of couplings.

I&#;d like to share with you why you should avoid coupling at all costs.

So what does coupling mean? To explain, I&#;ll need to refer to some research done in by Prelec and Loewenstein, two behavioural economists. Here are their exact words on what they learned from their study: "Coupling refers to the degree to which consumption calls to mind thoughts of payment and vice versa. Some financing methods, such as credit cards, tend to weaken coupling. Whereas others, such as cash payments, produce much tighter coupling. Sometimes this is referred to as saliency. What it means is that if we can change the way that we take money from the clients, we can reduce the association of payment pain."

Uber leads the way

I can give you a great example of how this works in practice by taking a look at the taxicab industry. I&#;m sure you&#;re aware of how it&#;s been revolutionised in the last few years by Uber.

In the past, you&#;d jump in a cab &#; perhaps a black cab in London, or a yellow one in New York &#; and sit there with no idea what the price was going to be. Then, at the end of the journey, when you got out and were told the final price, you&#;d take the cash &#; whether pound notes or dollar bills &#; out of your pocket and hand it over. That&#;s a perfect example of coupling. Of how it creates a greater association with pain through you having to physically take money out of your pocket.

In contrast, Uber provide an upfront price that you can pay by credit card. And, as Prelec and Loewenstein showed, when we pay for things by credit cards &#; because it's a piece of plastic, rather than cash from our pocket &#; the association with payment pain is less. (Perhaps that explains the huge escalation of credit card debt, too &#; people are far more willing to spend money using credit cards.) Uber have also got rid of the ticking clock on the meter, which is all part of the saliency. It's a reminder of the payment pain and that's all gone now.

How we can make clients happy to pay, too

What can we learn from this? Well, we need to make sure that when people pay for our accounting, bookkeeping or tax services, we offer methods that reduce the pain association. The worst method then would be a client having to take cash out of their pocket to give to us. Slightly better would be their writing a cheque. But best of all would be letting our clients pay by credit card.
