Highly flexible Stromag Periflex® VN Disc Coupling The Stromag Periflex® Disc Coupling concept Stromag Periflex® VN 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. Stromag Periflex® VN coupling allows fast and simple connection of a flange, specifically a flywheel, to a shaft. Some designs...

Highly flexible Stromag Periflex® VN Disc Coupling Instructions 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 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...

Highly flexible Stromag Periflex® VN Disc Coupling Fail-safe device The 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 permissible torques and speeds must be calculated separately on the basis of torsional vibrations transferred via a torsionally rigid structure. Instructions on choosing the coupling size The static and dynamic characteristics of Stromag Periflex®...

Highly flexible Stromag Periflex® VN Disc Coupling Installation instructions and scope of delivery The 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 tire (2) is secured to the machine with bolts (4). The drive and output sides are moved together to the prescribed distance (maybe blind installation), in this situation the tire’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...

1) The values listed in the tables refer to the disc tire characteristics. 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 PKVTO = 0,5 • PKV 60.

Highly flexible Stromag Periflex® VN Disc Coupling Stromag Periflex® VN coupling characteristics 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 An application factor of 1.2 is recommended for the simple design of a drive system based exclusively on the nominal torque. 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...
