GKN Stromag Periflex® Top Torque shaft coupling The GKN Stromag Periflex® Top Torque concept GKN Stromag Periflex® Top Torque is a highly flexible rubber-fabric coupling ideal for connecting two shafts in diesel engine and electric drives. The series covers the torque range 35 – 20500 Nm. Owing to the special design of its shaft tyre, GKN Stromag Periflex® Top Torque can absorb extremely large displacements, under low returning forces, in every direction (see specifications list) without suffering wear. On delivery, the tyre features as standard a separation joint for radial installation...

GKN Stromag Periflex® Top Torque shaft coupling Periflex Top Torque conforms to the requirements under Directive 94/9/EC (ATEX 95). From 1 July 2003, only those devices and components may be used in potentially explosive environments that comply with the requirements under the European Directive 94/9/EC. In other words, also nonelectrical equipment must be examined for compliance with these conditions before it is approved for use in potentially explosive environments. GKN Stromag Periflex® shaft couplings have been used in potentially explosive environments for many years, providing us...

GKN Stromag Periflex® Top Torque shaft coupling GKN Stromag Periflex® Top Torque assignments to electric motors GKN Stromag Periflex® Top Torque assignments to EN 50347 three phase asynchronous motors with squirrel cage, sizes 56 – 315 Motor size Motor power output at 3000 rpm (2 pole) P [kW] Motor power output at 1500 rpm (4 pole) P [kW] The assignments are based on application factor II for the usual load cases. When there are predominantly periodic vibrations on the system, the design must be based on DIN 740 Part 2. The GKN Stromag department can provide support, specifically in...

GKN Stromag Periflex® Top Torque shaft coupling Instructions for the designer General The coupling hubs and the thrust rings are of C45, St52, or similar and are provided with an anticorrosion coating. The coupling is secured with stainless steel grade A4 bolts that prevent rusting in the threads. The shaft tyre is of natural rubber with fabric inlays placed across the radius or diagonal. The torsional stiffness depends on how these fabric inlays are arranged. Flame retardant, electrically insulating, and oil resistant shaft tyres are available on request. On delivery, the shaft tyre...
