THE GKN STROmAG PERIflEx® DISC COUPlING CONCEPT > GKN Stromag PVN couplings are highly flexible elastomer couplings with linear spring characteristics ideal for diesel engine drives. The Series covers 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.The GKN Stromag PVN coupling allows fast and simple connection of a flange, specifically a flywheel, to a shaft. Some designs also allow the connection of two shafts. The GKN Stromag PVN coupling is a coupling that features an axial plug-in connection for easy installation and removal, for both the entire coupling and the flexible element.At the fully intermeshing teeth on the connection ring, the disc tyre can be displaced along its axis by several millimetres when no torque is applied.Each GKN Stromag PVN size comes with a range of elastomer qualities and torsional spring stiffnesses. These allow precise configurations for drives susceptible to torsional vibrations.
application fieldsGKN Stromag PVN 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.

INSTRUCTIONS fOR THE DESIGNER >The GKN Stromag Periflex® VN coupling hubs are of steel or ductile cast iron. The connec-tion ring is of aluminium. The disc tyres consist of a steel or ductile cast iron V ring with a lining of vulcanised elastomer. The variants of natural rubber (NR) can be used at tem-peratures of -50 °C to +80 °C. The variants of temperature resistant material (ECO) can be used at temperatures of -40 °C to +120 °C. In addition, ECO is resistant to ozone and oil. Damping work may cause the flexible element to reach temperatures higher than ambi-ent. 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 GKN 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 GKN Stromag AG departments.
use in potentially explosive environmentsThe coupling conforms to the requirements under Directive 94/9/EC (ATEx 95) and can be used as follows:a. Zone 1 (gas, Category 2G) in Groups IIA, IIB, and IIC, T4b. Zone 2 (gas, Category 3G) in Groups IIA, IIB, and IIC, T4c. Zone 22 (dust, Category 3D) for dusts with a minimum ignition energy
> 3 mJ, T 125 °C
The GKN 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 prod-ucts:
Use in gas atmospheres:
II 2G c T4
Use in dust atmospheres:
II 3D c 125 ºC
Use in potentially explosive environments must be based on the request form annexed to this catalogue.
classification rulesThe acceptance of a coupling by a classification society must observe the rules issued by this society. Under certain circumstances, the coupling characteristics may differ from the definitions provided in this catalogue. In such events, prepared data sheets are available on request. A number of classification societies prescribe fail-safe devices on ships’ main drives.

The static and dynamic characteristics of GKN Stromag Periflex® VN couplings are available. These can help in the choice of a coupling size suitable for the specific application. The key factors are the loads induced by the transferred power and torsional vibrations. Stationary operating modes must be based on T
KN, T
KW, and P
KV, nonstationary operating
modes on the TKmax
values.GKN Stromag AG departments can provide support, specifically in calculating the torsional vibrations. We therefore ask you to complete and send us the question sheet annexed to this catalogue. As a rule, flexible couplings are a safety feature in the form of a predetermined breaking point on a drive train. Hence, overloading a drive train generally leads to failure of the flexible coupling element. This behaviour is intentional and protects the entire system from unforeseen damage. Any consequential damage arising from this safety function of the coupling must be considered in advance by the system designer and monitored or eliminated with suitable measures.
INSTRUCTIONS ON CHOOSING THE COUPlING SIZE >
fail-safe deviceThe Stromag Periflex® VN coupling is available with an 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 maximum torques and speeds must be calculated separately on the basis of torsional vibrations transferred via a torsionally rigid structure.

INSTAllATION INSTRUCTIONS AND SCOPE Of DElIVERy >
The GKN Stromag Periflex® VN coupling is fitted with a connection ring (1) that allows it to be bolted directly to the engine’s flywheel. The hub (3) of the disc tyre (2) is secured to the machine with bolts (4).The drive and output sides are moved together to the prescribed distance (blind installation), whereby the tyre’s teeth must engage over the entire length of the connection ring.The maximum displacements can be taken from the dimensions and ratings tables.
Delivery of the standard version includes:
1 = connection ring2 = disc tyre3 = hub4 = bolts
Storing flexible rubber elementsWhen stored properly, flexible rubber elements retain their properties over several years. It is essential here that the stored parts are protected against oxygen, ozone, light, heat, moisture, and solvents. Solvents, fuels, lubricants, chemicals, acids, disinfectants, and similar may not be stored in the same room. The storage temperature should not be lower than +10 °C and no higher than +25 °C.All UV light sources are harmful and must be avoided. Equipment that generates ozone, e.g. light sources and electric motors, must be kept away from the storage location. The relative air humidity should not exceed 65 %.
further details can be taken from the DIN 7716 sheet.

GKN Stromag Periflex® VN Disc Coupling
32
∆kw
Max 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.
∆Kw ≥ ∆Ww
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
Tkw
The admissible permanent alternating torque describes the amplitude of the max permanent periodic torque fluctuation. This torque may be superimposed on a base load equal to TKN. This requires in addition an analysis of the max damping power PKV.
∆ka
Max axial displacement of the coupling. The shafts’ axial displacement ∆Wa must be less than ∆Ka.
The axial displacement for GKN Stromag Periflex® VN couplings depends on the installed connection ring. The disc tyre must always lie over its full width in the connection ring.
∆Ka ≥ ∆Wa
∆kr
Max radial displacement of the coupling. The shafts’ radial displacement ∆Wr must be less than ∆Kr.
∆Kr ≥ ∆Wr
GKN STROmAG PERIflEx® VN COUPlING CHARACTERISTICS >
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 GKN Stromag Periflex®VN coupling with peak torques Tmax2 in a system’s anoma-lous nonstationary 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 scheme (e.g. emergency stops, sync failure, short circuits, etc.).
TKmax • 1,5 ≥ Tmax2
33
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 GKN Stro-mag 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 frequency of 10 Hz on a coupling at operating temperature, with a surface temperature of about 30 °C.
CTdyn =
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) and CTdyn A (1.35).

Ca
The axial spring stiffness represents the ratio of axial reaction force to axial displacement. GKN Stromag Periflex® VN couplings do not generate axial forces when the disc tyre 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 50 °C.
