FLEXIBLE ALL METAL COUPLINGS Introduction The large number of flexible couplings successfully put into service over the past few years indicates an increasing popularity for this type in any application, besides on high power and high speed applications.

It will be shown that, by careful design and choice of material, the power/weight ratio can be increased to meet the low hung weight requirements of current and future design trends in high speed machinery.

Description of the flexible element The flexible elements have driving and driven bolts on a common pitch circle diameter. Drawings A illustrate the continuous ring types; drawing B illustrate the separate link types.

The flexible elements transmit torque uniformly working on the principle of a direct pull between driving and driven bolt, and this will produce a simple tensile stress in the blade. The flexible element transmit torque by a simple tensile force between alternate driving and driven bolts on a common pitch circle diameter and flexibility, which is derived from the span between adjacent bolts, will vary as the cube of the free length. Operational Charateristics In operation the trailing blade will be in tension and the leading blade will be in compression. The applying of an axial force produce an axial deflection y and, in doing this, the free length of the blade will be stretched . It can be shown that, as a first approximation the axial force varies approximately as the cube of deflection. With a force, due to transmitted torque, applied to the driving bolts, the original length of the trailing blade is increased whilst the distance between driving and driven bolts, on the leading side, is less than the free length. As the leading blade is now slack, the trailing blade can be deflected axially without suffering further extension, so that the force required to move the blade axially will be directly proportional to the deflection, and will remain linear until the deflection is sufficient to remove all slack in the leading blade when the distance between driving and driven bolts will be equal to the original free length.

A B B


A further condition will affect the axial force is the effect of speed. Depending on the physical size of the coupling, the effect of centrifugal force will normally be small at low speed, but may have a very significant effect at high speed. Under condition of high speed there will be increase in bolt pitch circle which can be related to a strain in the blades so that the original length of all blades is increased. Consideration Laminated membrane couplings, however, are not only chosen solely on a consideration of axial thrust, but more frequently on a basis of allowable misalignment. The generated thrust being more commonly a secondary consideration and normally well within the capability of associated thrust bearings. End thrust is present in a gear coupling for a very different reason, having nothing to do with the elastic properties of the material but solely due to the loading on the teeth and the coefficient of friction between then. This thrust, the presence of which is frequently overlooked in gear couplings, can be a major cause of failure in double helical gearboxes. The most likely cause of failure in laminated membrane coupling is bending fatigue of the laminations close to their anchor points, and it is therefore important that the flexible elements should, at all times, work within the limits of allowable fluctuating stress. Stresses due to a torque and pure axial deflection can be considered as steady stress, and those due to angular misalignment as fluctuating. Parallel misalignment applied to a spacer coupling is achieved by causing both elements to tilt. In this sense, parallel shaft misalignment which may exist can, therefore, add to or subtract from the allowable parallel misallignment. Conclusions One of the virtutes of the laminated membrane coupling is its versatility an the ease with which its design can be modified to suit particular requirements.


Coupling selection The selection of coupling size and type will be dependant on several factors. The first requirement must obviously be to choose a unit of adequate size of transmit the maximum torque and for this purpose it is advisable to use the actual available power of the driving machine rather than the calculated absorbed power of the driven machine, unless this latter is known not be exceeded. Having determined the maximum HP or KW to be transmitted, this is divided by the speed to give the HP or KW/rpm so that, by comparison with the technical data, a selection can be made from any of the various coupling types. If the type of applicationdemands the use of a Service Factor this should be applied before selecting the coupling size. If the resulting specific rating falls between two coupling size, the larger should be selected. The standard coupling will withstand a short circuit torque (C.C.) of 2,5 times the nominal torque. When the C.C. exceeds 2,5 times nominal size the coupling from: HP (KW x 1,36) x 716,2 x 9,81 x C.C. x Service Factor ----------------------------------------------------------------------------------------- rpm x 2,5 x Nominal Torque For direct on line motors, where the starting torque does not exceed 2 x nominal, use a Service Factor of 1,5, unless the Service Factor already applied for the particular application is 1,5 or greater, inwich case no Service Factor need be applied; if the starting torque is greather than 2 x nominal,determine the required size from: HP (KW x 1,36) x 716,2 x 9,81 Max expected torque Nominal Torque = ------------------------------------------- x ---------------------------------- rpm 1,5 x Nominal Torque Having determined the coupling rating, the required flexibility must be considered from an assessment of the shaft movements, comparing these with relative technical data. A final check should be made to ensure that the maximum hub bore dimension is adequate for the shaft. Providing, after the selection is made, other factors such as weight, torsional stiffness etc, as given in the appropriate tables are acceptable then a standard unit can be selected. If not consult our technical department who are always willing to give advice and produce special designs outside the catalogue dimensions if required. It should be noted that, throughout the catalogue, the coupling size indicates its rated capacity in Nm: for instance coupling LSDA 1700-6 is an 6 bolt coupling with a rated capacity of 1700 Nm.

For coupling with spacer the centre section can be considered as weight (spacer) suspend between 2 springs (flexible elements) and , as such this centre section will have natural frequency which, if excited, can cause the spacer to oscillate to such a degree as to lead to the eventual failure of the flexible elements. There is nothing within the coupling to cause the spacer to vibrate so, for this to happen, an exterior exciting force of the same frequency as the natural frequency of the spacer is required. In practice this is very rarely a problem and is normally only of any significance when the driving or driven machinery is of the reciprocating type. Unfortunately it in not possible to present, in a concise form, value foe the natural axial frequency of a particular coupling due to the fact that the spring rate of the flexible element is not linear under all operating conditions and that the frequency will vary according to speed of operation and torque transmitted. To reduce the natural axial frequency it is advisable to set the flange face to face dimension 1,5 to 2 mm greater than nominal “S” in order to minimise the chance of axial spacer oscillation.

GENERAL INFORMATION The nominal power ratings (HP/rpm and KW/rpm) apply to: shock-free operating, daily operating period of 24 h, 2 start by hour, two times, the listed torque being permissible during starting, properly aligned shaft, ambient temperatures –20° to 250°. Where operating conditions differ from those listed,the service factors must be taken into consideration for mechanical stress. All GTS coupling are designed and manufactured in accordance and in conformity with the provision of the Torsional stiffness is given between hub flanges for standard dimension. Maximum speed are for standard couplings. For higher operational speed alternative materials or designs are available. Both axial and parallel misalignment must be considered in combination as one will reduce with an increase in the other. PARTICULAR INFORMATIONS To find the axial thrust (with an approximation of 20% more on less) on the grounds of axial misalignment to use the following table bearing in mind that for a percent value of the axial misalignment (x) will correspond a percent value of the axial thrust (y)

The keyless shaft hub connection “ACE” eliminates the play between the shaft and the hub and distributes the power transmissions over the entire surface while with a key con-nection the transmission is concentrated on a limited area only. Simple mounting and dis-mounting allows easy and quick changing of the hubs fitted on the shaft; the high pressure between the contact surfaces avoid rust and, years after installation , allows a quick re-moval of the hub.

Special executions

For retention and repeatability of balance in high speed couplings to adopt that illustrated: the adaptor and spacer are accurately located through the flexible element, so en-suring concentricity whilst allowing full flexibility.

Execution for high speed HSE Range

On application involving electric motor driven pumps, it is often nec-essary to insulate against eddy cur-rents. Such insulation can readily be introduced between adaptor and hub as illustrated.

EIE Range

For ease of fitting hubs to shafts it is possible to include taper bushes or the ringfedder system of attachment.

RFE Range

With shear pins

PRE Range

When fitting direct to customer’s existing shaft flangest will often be found that the attachment hole arrangement, or the di-ameter of flange, will not conveniently fit with conventional adaptor plate. In such cases special adapters are used as illus-trated.

CFE Range

In some instances, due to a very small shaft separation, it is not practicable to fit a con-ventional type of spacer. In these cases it is often possible to make the spacer portion in the form of single plate.

SRE Range

With reversed hubs and spacer in to half

GCE Range

For vertical applications, particu-larly when using long or heavy units, it is necessary to support the weight of the spacer to prevent damage to the flexible elements. This can be done by the simple method illustrated where the thrust bearing of the lower machine takes the weight.

ASSEMBLY The user is responsible for the provision of safety guards and correct installation of all equipment It is important that initial alignment should be as close as practicable, both axially and radially, to allow for changes in condition during operation and ensure a long working life.

Parallel bored hubs should be fitted so that the shaft end is flush with the flange face. The “S” dimension will them be the same as the distance between shaft ends. Hubs bored for interference fit should be heated in oil at 120° - 140° C, and quickly positioned on the shaft. Do not spot heat as it may cause local distortion. Couplings whit adaptors, LSDA, are fitted to the hubs by means of spigoto register. To assemble or dismantle the central “S” portion requires it to be compressed by an amount of at least twice the spigot depth. This can be achieved by the use of special compression caps or cradle. In the case of smaller units compression of the centre section is possible by inserting a screw driver between adaptor and hub flange taking care not to damage the mating surfaces. The “S” is therefore a pre-assembled set: so is very simple and fast to take out if for routine maintenance to the machines, without removing the alignment.

An initial and rough radial alignment can be made by laying a straight edge across the flanges of the two hubs. Remember to check in the vertical as well as the horizontal plane.

s


Having brought the two ends into a roughly correct position the centre section of the coupling can now be assembled and final alignment achieved as follows to check the angular and radial misalignment simultaneously: 1 – Attach a dial indicator to one flange and,

Assembled the coupling, establish the minimum reading. 2 – To accurately measure either over the flange or the element gap, applying minimum pressure, to obtain

the high point S2 and the low point S1:

Divide the difference between point S“ and S1 by the coupling flange diameter “E“. This procedure will give an answer in mm/mm which should not be larger than the figure given below: 4 bolt coupling 0,004 mm/mm of flange diameter “E” 6 bolt coupling 0,003 mm/mm of flange diameter “E” 8 bolt coupling 0,002 mm/mm of flange diameter “E”
