GENERAL DESCRIPTION

1

With decades of experience and thousands of applications onTransfluid fluid couplings the BT flexible coupling line has beenexpanded to include couplings for shaft-to-shaft application. Thenew series has been studied to provide an exceptionally robustcoupling with excellent misalignment capabilities and easyinstallation and assembly. The B3M/BM/BMS couplings highquality flexible elements provide reliable performance whileprotecting the coupled machines.

The B3M/BM/BMS require minimal maintenance except for aperiodical inspection and replacement of the rubber elements.To simplify in this check, especially in alignment free drives, theB3M was developed. This version allows for inspection andremoval of the rubber elements while preserving alignment.

Manufactured with the highest quality materials in Transfluid'snew factory in Gallarate Italy the new B3M/BM/BMS series isavailable in 17 different sizes with torque capability exceeding33100Nm (24,494 lbs-ft)

ADVANTAGES:– Compensation of misalignments– Shocks and vibrations damping– Fail - safe and capable of withstanding high overloads – Quick and easy change of flexible elements– Maintenance free

COUPLING SIZE SELECTION


The coupling must be selected so that the operating conditionsof the coupling, do not exceed the maximum allowable load ofthe coupling itself. For driving machines not generating cyclictorque loads the selection of the coupling can be performedusing the driving torque and the corresponding service factor.When the driving machine generates cyclic torque loads (e.g.internal combustion engines) the selection of the coupling mustbe checked by a torsional analysis of the complete system.Steps to be followed are as follows.

1) Using the power and rotational speed, calculate the torque ofthe driving machine TAN:

where:P = power of driving machine (kW) - n = rotational speed ofdriving machine (rpm)TAN = torque of driving machine (Nm)

2) Once the torque of the driving machine TAN has beencalculated, determine the service factor and check that thetorque of the driving machine times the service factor,temperature factor and starting factor is lower than thecharacteristic torque of the chosen coupling TKN:

where:TKN = characteristic torque of the chosen coupling (Nm)- Sm =service factor from table Tab. 4 and Tab. 6St = temperature factor from table Tab. 3 -Sz = starting factorfrom table Tab. 5SAtex = 1,2 in case of use in hazardous zones acc. to 94/9/EC(Atex). In normal zones, SAtex = 1

Load classifications and service factors of Tab. 6 are referred toturbines and hydraulic or electric motor as the prime mover. If theprime mover is a single or multi cylinder engine, the servicefactor from the Tab.6 must be replaced by its correspondingvalue from Tab. 4

3) Known the maximum possible torque during operation Tmax,check that the maximum torque times the temperature factor islower than the maximum characteristic torque of the chosencoupling TKmax:

Calculation example

1) Application dataA torsionally elastic coupling type BM installed between anelectric motor and a rotary pump gear type.Power of the electric motor: P = 160 kWRotational speed: n = 1490 rpm2) Calculation of driving torque TAN

The driving torque TAN of the driving machine is:

3) Check of the nominal TKN

From table Tab. 6 the service factor corresponding to the drivenmachine load classification is: Sm = 1.5. Because the primemover is an electric motor, it is not necessary to use conversiontable Tab. 4From table Tab. 3 for an ambient temperature of 40 °C, thetemperature factor is: St = 1.1From table Tab. 5 for starting frequency per hour of 60 thestarting factor is: Sz = 1.1The nominal torque TKN of the driving machine is:

4) Selection of the couplingFrom table Tab. 1, with torque values TKN > = 1861 Nm thechoice is for coupling size BM 50.

5) As final selection step, check compatibility betweenequipment shaft and max allowable bore of selected coupling

TAN = 9550 x P / n

TKN >= TAN x Sm x St x Sz x SAtex

TKmax >= Tmax x St

TAN = 9550 x 160 / 1490 = 1025 Nm

TKN >= 1025 Nm x 1.5 x 1.1 x 1.1 = 1861 Nm

Max shaft misalignment (up to 1800 rpm)

TAB. 10

Flexible couplings BM series can withstand radial, axial, angular misalignment values according to Tab. 10; such values are justapproximate values because the coupling compensation capability depends on applied load and rotational speed values. It isrecommended anyway to perform the best possible alignment during installation.

Y

H1

H2

For operating rotational speed higher than 1800 rpm, it isrecommended to reduce by 50% the max allowablemisalignment.Maximum rotational speed cannot exceed the allowable valuesindicated at Tab. 1 pag. 3.

BALANCINGAll couplings are balanced according to ISO 1940 G16 as astandard which is suitable for normal speed range. Higherbalancing quality according to G6.3 is available upon request.

MAINTENANCEReplace rubber elements when total thickness is lower than 90%of its nominal dimension (see dimension data on Tab. 13).ATTENTION: the rubber elements must never get in contact withpaint thinner, petrol or other chemicals.

SAFETYThe couplings must be installed complete with proper protectionguards in order to provide complete safety for personnel duringoperation. The installer and the end user are responsible toassure adequate protection of the rotating parts and to comply tothe required standards of the Country where the equipment isinstalled.
