BENEFITS INCLUDE
STROMAG PERIFLEX® VN DISC COUPLINGS
• Periflex® VN Couplings are highly flexible elastomer couplings with
linear spring characteristics ideal for diesel engine drives.
• Allow fast and simple connection of a flange, especially a flywheel,
to a shaft. Some designs also allow the connection of two shafts.
• Periflex® VN Couplings are couplings that features an axial plug-
in connection for easy installation and removal, for both the entire
coupling and the flexible element.
• Come with each with a range of elastomer qualities and torsional
spring stiffnesses. These allow precise configurations for drives
susceptible to torsional vibrations.
• Cover the torque range 160 – 63,000 Nm. The external companion
dimensions conform as standard to the flywheel connections under the
SAE standard J620.
The larger couplings are basically designed with metric flywheel
connections.
• At the fully intermeshing teeth on the connection ring, the disc tire can
be displaced along its axis by several millimetres when no torque is
applied.
• On request, high temperature mixture available for stationary systems
up to 8000 Nm.

APPLICATIONS AREAS
• Stromag Periflex® VN couplings are designed for use on piston engines. The connection ring can be bolted directly to the flywheel of an engine or compressor.
• Its axial plug-in design presents particular advantages e.g. for installations under bell covers.
• Other application fields are electrical assemblies, compressors, construction machinery, engine and shipbuilding and general machinery.
FAIL-SAFE DEVICE
The Stromag Periflex® VN coupling is available with a fail-safe device. A rupture in the flexible element causes claws to intermesh, forming a torsionally rigid, backlash connection between the drive and output sides. Temporary emergency operation is possible with limited torque. The permissible torques and speeds must be calculated separately on the basis of torsional vibrations transferred via a torsionally rigid structure.

TORQUE RANGE
• 160 up to 63,000 Nm
For survey of the coupling by a classification society, the regulations of the society have to be adhered to. The coupling characteristics may differ from the definitions given in this catalogue. Accordingly prepared data sheets are available on request.
A number of classification societies prescribe fail-safe devices on ships main drives.
CLASSIFICATIONS
INSTRUCTION FOR THE DESIGNER
The Stromag Periflex® VN coupling hubs are made of steel or ductile cast iron. The connection ring is made of aluminium. The disc tires consist of a steel or ductile cast iron angular ring with a volume of vulcanized elastomer. The variants of natural rubber (NR) can be used at temperatures of -50°C to +80°C. The high temperature Coupling variant can be used from -30 °C up to 120 °C.
Damping work may cause the flexible element to reach temperatures higher than ambient. This must be considered when the coupling is to be fitted with a guard or cowl, and adequate ventilation and heat dissipation must be provided.
The Stromag Periflex® VN coupling can be delivered with EN 10204 acceptance as defined in the classification societies rules.
The coupling complies with the requirements under API 671 with consideration to our list of deviations TM 800.0010.
This list of deviations is available from the Stromag GmbH departments.
USE IN POTENCIALLY EXPLOSIVE ENVIROMENTS
The coupling conforms to the requirements under Directive 2014/34/EU and can be used as follows:
a. Zone 1 (gas, Category 2G) in Groups IIA, IIB, and IIC, T4
b. Zone 2 (gas, Category 3G) in Groups IIA, IIB, and IIC, T4
c. Zone 22 (dust, Category 3D) for dusts with a minimum ignition energy > 3 mJ, T 125 °C
The Stromag Periflex® VN coupling compliance with the requirements for each of these zones / categories is documented in the form of the following codes on our products:
Use in gas atmospheres:
II 2G Ex h IIC (T4) Gb
Use in potentially explosive environments must be based on the request form annexed to this catalogue.
Use in dust atmospheres:
II 3D Ex h IIIC T120°C Dc

Stromag‘s Know-how in Torsional Vibration Analysis (TVA) constitutes the core of each coupling design. It provides a comprehensive analysis of loads in the crankshaft, cou-pling and driven side to ensure that no critical speeds occur during operation.
Unevenly rotating systems can severely degrade product quality and cause great harm to the powertrain. On a daily basis, the TVA experts at Stromag work on the challenge of detecting such deviations by measuring them and protecting the entire powertrain with ideal product selection. Stromag is capable of calculating stationary and transient operating conditions considering the stiffness and damping of the elastomers.

1) The values listed in the tables refer to the disc tire characteristics.
2) For: TW = 0,2 • TKN; T = 0,8 • TKN; f = 10 Hz; ϑ = 30°C
3) This value must be reduced by the temperature factor when the coupling temperatures are higher than 30°C.
4) Tolerances on the materials may be as high as ±15%.
5) PKV 60 value represents the damping power that can be absorbed over a period of 60 minutes.
The damping power that can be absorbed permanently is PKV∞ = 0,5 • PKV 60.

TKN
The coupling’s nominal torque can be permanently transferred over the whole permitted speed range.It must be higher than the system’s nominal torque TN
TKN ≥ TN
An application factor of 1.2 is recommended for the simple design of a drive system based exclusively on the nominal torque. TKN ≥ TN • 1,2
TKmax
The coupling´s max torque TKmax can be endured as a peak load and may not be exceeded by peak torques Tmax1 when the system is operating in normal, nonstationary mode.
A system’s normal nonstationary modes are unavoidable and occur repeatedly (e.g. starting/stopping, resonance passes, switchovers, accelerations, etc.).
TKmax ≥ Tmax1
Overloading the Stromag Periflex® VN coupling with peak torques Tmax2 in a system’s anomalous nonstatio-nary mode shortens the service life and is tolerated in individual cases.
A system’s anomalous nonstationary modes are avoidable and are not part of the planned operating sche-me (e.g. emergency stops, sync failure, short circuits, etc.).
TKmax
• 1,5 ≥ Tmax2
TKw
The admissible permanent alternating torque indicates the amplitude of the admissible permanent periodic torque variation. This torque may be superimposed on a base load of TKN.
In this process, the maximum damping power PKV must also be checked.
Ψ
The relative damping is a measure of the ability of the coupling to convert part of the vibration energy into heat.
The Ψ data relate to a coupling torque of 0.8 • TKN, an alternating torque of 0.2 • TKN, and a frequency of 10 Hz on a coupling at operating temperature, with a surface temperature of about 30°C.
Pkv
The admissible damping power indicates how much damping (heat) the coupling can permanently absorb resp. dissipate.The sum of the damping power of each vibration order (i.e. ΣPVi)) must be less than the damping power of the coupling.
Pvi =π

PKV ≥ ΣPVi
The stated value PKV60 describes the damping power which can be absorbed over the period of 1 hour. To determine the damping power which can be permanently absorbed (PKV ∞),the value PKV60 has to be multiplied by the factor 0.5. With an ambient temperature TU higher than 30ºC, the admissible damping power must be reduced by the temperature factor SϑPKV.

Temperature factors SϑPKV
Temperature factors shall take into consideration the reduction of the physical characteristics of rubber-flexible material caused by heating.
The coupling temperature is determined by the ambient temperature plus an internal heating caused by internal material friction in the rubber volume, resulting from alternating torques and alternating loads due to shaft offsets.
With higher ambient temperatures the coupling characteristic value PKV must be reduced through the corresponding temperature factor SϑPKV.
∆Ka
Maximum axial displacement of the coupling. The shafts’ axial displacement ∆Wa must be less than ∆Ka.
The axial displacement for Stromag Periflex® VN couplings depends on the installed connection ring. The disc tire must always lie over its full width in the connection ring.
∆Ka ≥ ∆Wa
∆Kr
Maximum radial displacement of the coupling.The shafts’ radial displacement ∆Wr must be less than ∆Kr.
∆Kr ≥ ∆Wr
∆Kw
Maximum angular displacement of the coupling. The shafts’ angular displacement ∆WW must be less than ∆KW.
A ∆KW value of 0.5° is permitted for Periflex® VN couplings. This value, however, may be utilised to the full only when there are no other options for shaft displacement.

Ca
The axial spring stiffness represents the ratio of axial reaction force to axial displacement.
Stromag Periflex® VN couplings do not generate axial forces when the disc tire lies over its full width in the connection ring.
Ca = 0
Cr
The radial stiffness represents the ratio of radial reaction force to radial displacement. The specified values apply to the coupling at operating temperature, with a surface temperature of about 30°C.
CTdyn
The dynamic torsional spring stiffness represents the ratio of torque amplitude to torque angle during an oscillation.
The torque amplitude is superimposed on an initial load (coupling torque). The Stromag Periflex® VN coupling’s CTdyn value remains constant over the coupling torque (linear characteristic curve), but changes with the amplitude, frequency, and temperature of the flexible element.
The specified nominal values for CTdyn are based on a coupling torque of 0.8 • TKN, an alternating torque of 0.2 • TKN, and a fre-quency of 10 Hz on a coupling at operating temperature, with a surface temperature of about 30°C.
CTdyn warm
takes into account that high power dissipation causes the coupling to heat up.CTdyn warm = 0.7 • CTdyn
CTdyn A
takes into account the effects of a small alternating torque amplitude.CTdyn A = 1.35 • CTdyn
Calculations of torsional vibrations in the system are recommended to include CTdyn warm (0.7), und CTdyn A (1.35)
