Periflex VN Disc Couplings: Features/Applications | Stromag

Stromag Periflex VN is a highly flexible elastomer coupling with linear spring characteristics ideal for diesel engine drives. It allows a fast and simple connection of a flange, especially a flywheel, to a shaft. Some designs also allow the connection of two shafts. Hubs are made of steel or ductile cast iron. The connection ring is made of aluminum. 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. The Series covers the torque range of 160 – 63,000 Nm. The external companion dimensions conform to the flywheel connections under the SAE standard J620. The larger couplings are designed with metric flywheel connections. Stromag Periflex® VN coupling allows a fast and simple connection of a flange, specifically a flywheel, to a shaft. Some designs also allow the connection of two shafts.

 

Features 

 

• Highly flexible rubber couplings
• Ambient temperatures up to 120 °C where continuous operation permitted
• Sizes according to SAE standard
• Improved media resistance to oil and ozone
• Good abrasion resistance

 

Applications

 

• Block heat and power plant
• Pump-Set applications (diesel-pump)
• Marine applications
• Gen-Set applications (diesel-generator
• Agriculture and construction machinery
• Compressor-Set applications (diesel-compressor)

 

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 based on torsional vibrations transferred via a torsionally rigid structure.
