CENTAFLEX-DS

2-phase coupling

The CENTAFLEX DUAL STAGE is one of a kind. The coupling has been specially developed for mounting between diesel engines and flanged reduction gearboxes. The CENTAFLEX-DS has a first phase that is very soft from a torsion point of view. This is to prevent the well-known ‘tooth hammering’ at low engine speeds. With large transferable powers, the harder, robust and anti-rotation second stage comes into operation. For mounting in areas with high ambient temperatures, different compositions for the rubber parts are available, such as silicone for example.

Application

Ship Main Drives:

  • between the diesel engine and the flanged gearbox
  • between the diesel engine and the free-standing gearbox

Ship auxiliary drives with a high percentage of idling:

  • with clutches
  • fire pumps
  • etc.

Characteristics

  • Simple, compact, reliable and economical design.
  • Extremely low torsional stiffness at low revs (idling), enabling low engine speed without tooth hammering.
  • The second stage is based on the ‘claw clutch’ type and transmits the higher powers.
  • The rubber parts are only loaded in compression; there are no rubber-metal connections and/or shear loads. In other words, the rubber parts are optimally loaded. This, in combination with the excellent internal ventilation, guarantees a long life.
  • Spin-proof.
  • A wide range suitable for mounting on SAE flywheels and almost all possible reduction gearboxes is available from stock.
  • Suitable for so-called blind mounting in flywheel housings.
  • Suitable for cylindrical and conical input shaft as well as input shaft with pline connection.
