Periflex disc type VN 66631 R3.1 flexible coupling

Description

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 di¬mensions conform as standard to the flywheel connections under the SAE standard J620. The larger couplings are basically designed with metric flywheel connections. The PVN coupling allows fast and simple connection of a flange, specifically a fly¬wheel, to a shaft. Some designs also allow the connection of two shafts. The 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 PVN size comes with a range of elastomer qualities and torsional spring stiffnesses. These allow precise configurations for drives susceptible to torsional vibrations.
