Flywheel couplings

  • 17-Jun-2009 08:44 EDT

Seven new Arcusaflex flywheel coupling sizes by Reich Kupplungen are available from Ringfeder for larger engine applications. The couplings come in sizes AC 4.1, AC 4.9, AC 5.1, AC 6.1, AC 6.5, AC 13, and AC 13D. The additions bring the total to 21 different sizes, with torque ranges from 1770 to 973,580 lb·in (200 to 110,000 N·m), which corresponds to about 6500 kW (8720 hp) at 1000 rpm. All couplings are available in standard rubber as well as a silicone mixture to provide heat resistance in high-temperature applications. The units meet European explosion protection standards set by ATEX 95 and are also certified for use in hazardous locations (Categories M2, 2+3) according to the 64/9/EC directive. They are highly flexible to provide a torsionally soft connection between an internal-combustion engine and the driven components of generators, compressors, and pumps. A rubber disc element is vulcanized to a choice of bolt-on sleeve or taper bushing hubs, providing high torsional flexibility and shock absorption capability in reciprocating engine work environments that may undergo high angular, axial, and/or parallel misalignments.
